The main cause of the cold in houses and overpayment for heating - heat loss through the enclosing structures. Basically, construction is conducted from brick and concrete. They do not keep warmly warm. Facade of houses unprotected from atmospheric phenomena are quickly destroyed, their appearance spars. These problems are solved using a wet facade technology with their own hands.

Wet facade at home

Wet facade is the basic technology of insulation of houses, protect facades from negative impact ambient. Includes cladding of walls insulation and subsequent plaster.

The plastering solution is prepared on a water basis, so in the title there is the word "wet". The standard variant of the wet facade consists of 6 layers:

• glue mix;
• insulation sheets;
• plastic anchor;
• plastering stack;
• layer of facade plaster;
• decorative plaster or facade paint.

The technology has several advantages and disadvantages compared to other facade facing options.

Benefits:

• Good thermal insulation. The wet facade, with a thickness of the insulation layer of 50-100 mm is equivalent to two rows of ceramic bricks.
• Ease. Absence metal carcass makes it possible to apply this technology in residential, public and production buildings. Stress on bearing walls minimum.
• Soundproofing. The insulation devastates most of the sounds and shock waves.
• Integrity. The device of the wet facade, in contrast to the framework, does not provide for the installation of profiles. Cold bridges are absent. Heat does not leave the interior.
• The correct dew point. If you follow the recommendations on installation, then condensate will fall out beyond the building. Interior walls Do not get wet.
• Strength and durability. Wet facade reliably protects building construction from destruction. The term of its operation is 15-20 years.
• Maintainability. All the care of the facade surface is to update the color and putting on cracks.
• Easy installation of construction. Each homeowner will be able to master the facade insulation rules wet method And do it with your own hands.

Disadvantages:

• Restriction for work when negative temperatures air. Cannot be performed finishing work on the street wet late in autumn And in winter.
• The need to use only high-quality building materials of the factory production and follow the instructions for their use. Violation of work technology, poor-quality material may cause peeling of the plastering layer or the destruction of the facade.

We select insulation

This is the basis of the facade. It should be durable, easy and fire-resistant, to remove the excess moisture (vapor permeability). The most common materials are polystyrene foam and basalt mineral wool.

Compare what insulation is suitable for it:

• Strength - expanded polystyrene has an average indicator for strength. Density stone wati much higher.
• Easy - the mass of basalt mineral wool is slightly higher than that of polystyrene foam. This is leveled by its stock in strength.
• Parry permeability - mineral wool is an order of magnitude to polystyrene foam, which practically does not conduct moisture.
• Fire resistance - unlike foaming, stone wool does not burn and does not emit harmful substances.

Mineral wool

Based on comparative analysis, we conclude that mineral wool - the best way For insulation using a wet facade technology. She is stronger and more reliable. Its vapor permeability allows you to well evaporate the condensed moisture. Mineral wool corresponds to modern fire standards and rules.

The thickness of the insulation depends on several factors:

• Climate district. For different areas there are different norms on the thermal conductivity of the enclosing structures. From this depends the thickness of the insulation layer.
• Wall base material. Brick, concrete, foam block have different thermal conductivity. With the same wall thickness of these materials, a different amount of insulation is needed.

Excess insulation is also harmful, as well as disadvantage. Excessive heat provokes constant ventilation. Condensate is formed around open windows, which flows through the insulation. As a result, the wall flogs and begins to collapse.

Required building materials and rules for their calculation

Before the beginning mounting work It is necessary to prepare all the materials and tools. The disadvantage of the material will slow down the course of work, the oversupprance - will lead to the appreciation.

• Basalt mineral wool. After determining with a layer thickness, you need to calculate necessary volume. There are two sizes of plates 1000 × 600 and 1200 × 600 mm. First, the walls are calculated and 10% is added (stock for trimming and marriage). Then the area of \u200b\u200bone sheet of mineral wool is calculated. The total area is divided into one. As a result, it turns out required amount Heat sheets.

The walls of the walls are calculated without taking into account window and doorways.

• Guide profile. It is measured by straight meters. Its amount is equal to the perimeter of the building plus a 10% stock. The profile width must coincide with the basalt wool sheet width. The number of connector for the profile is calculated from the norm of 4 pcs. For one craving.

Ground profile

• Dowel - nails. These are fasteners for the guide profile. The size depends on the material of the wall. Long - for loose materials (aerated concrete, foam block), short - for solid (brick, concrete). Consumption rate - 1 pc. By 30-50 cm profile.
• Conconduct. It serves to improve adhesion between glue and the wall. Consumption rate of 300-500 ml / m 2.
• Adhesive mixture for stone wool. There are universal compositions for all types of insulation, but it is recommended to select a specific material. Consumption rate of 4-8 kg / m 2.
• Speed \u200b\u200bdowels. Additionally fasten the mineral wool. Their length depends on the thickness of the insulation. Consumption rate 5-6 pcs / m 2.
• Facade plaster. The thickness of the layer is 4-8 mm. Consumption rate of 4-8 kg / m 2.
• Facade mesh. There is plastic, metal, fiberglass. Consumption rate of 1.1 ppm 1 m 2 surfaces.

Facade mesh

• Plastic Corners for Plasterings window slopes. Measured in the route meters. The total length is equal to the perimeter of the windows plus 10% of the stock.
• Priming. Consumption rate of 200-300 g / m 2.
• Decorative plaster or facade paint. Selected depending on the wishes and preferences of the client. The cost of consumption is greatly different. It is better to clarify the specific manufacturer.

Works on the device of the wet facade do it yourself

After completion of the calculations, the preparation of all materials and tools begins the main stage - finishing the facade. It is performed sequentially, adhering to certain rules:

Preparatory work

The surface of the facade is carried out, problem areas are determined and eliminated:

Preparatory work

• Old paint. Hinders the clutch of the wall with facade glue. The surface is inspired by an iron brush or a grinder.
• Old stucco. Weak areas are fought off, the cracks are expanded and zamaznated by cement mortar.
• Slops of the solution. Fell up with a hammer, chisel or spatula.
• Small irregularities. Close up with facade glue or cement-sandy mixture.

The surface of the wall surface is greater than 2 cm on 2 m are aligned with cement-sandy solution.

• Extraneous elements. Cut or hubs cement mortar.

Installation of the guide profile

This is a foundation that the insulation will be ashamed for a wet facade. The load is uniformly distributed. No overloaded sections are formed.

First of all, the horizon is littered. Horizontal line draws around the perimeter of the facade with laser level, Leveling and ropes. Height from Earth 300-400 mm. It will not give mineral wool to get on a wet soil.

Then the profile is fixed. It is mounted strictly along the battered line with a dowel-nail or dowel-samphs. Step installation of fastening elements 300-500 mm. The profile combines with special fasteners with a deformation gap of 2-4 mm.

If the profile width is less than 80 mm, then 2 fasteners are enough. If more than 80 mm, then 4 pcs.

The ends of the angular profiles are cut under 45 °. Then connect. The deformation clearance is left 2-4 mm.

Installation of insulation

The glue is mixed. It is better to use plastic container, for example, buckets from facade paint. A part of the water is poured into the bucket. Then the glue is hurt, and water residues are poured. The solution is mixed with a mixer.

It is better to use a special knife for sawing sheets of stone wool. Another tool "Rivets" the cut line.

The glue is applied by mineral plate Ribbed spatula throughout the area. Then the leaf of the insulation with an effort is pressed against the wall. Installation begins from the corner of the bottom row.

The first row of the insulation should be tightly standing on the guide profile.

Sheets glue in a checker order. Seam in the seam glue is strictly prohibited. Minimum size The element of the insulation, which is attached to the corner of 200 mm. All angles are tied to the castle rule (similar to the dressing of brickwork).

Installation of insulation

Special attention should be paid to the slopes. They are separated by stone wool sheets less thickness.

It is prohibited to match the vertical and horizontal seams of the insulation with the lines of slopes. There is a gleaming between them.

• The verticality of the facade plane is checked using a construction level of 2-2.5 m.
• The glue mixture will dry 72 hours. Then the insulation is additionally attached to the wall with plastic dowels. For each sheet you need 5 pcs.
• Holes under fasteners are drilled with a perforator and a boome of concrete. The depth is set at the calculation of the size of the dowel plus 20-100 mm.

The depth of drilling depends on the material of the wall. For foam concrete - 100 mm. For bricks - 20 mm.

• All the slots between the sheets are closed with rock wool slices carved in the form of a wedge.

Plastering

A special plaster composition for facades is used. It is divorced in water and is stirred by a mixer.

Plastering

First reinforce the angles and slopes. Strips of the solution are applied along the gear spatula and plastic corners are attached.

Then the main surface of the facade is placed. Work is better to start from the corner. The first layer of plaster 2-3 mm is applied. The front grid is pressed into it. After 20-30 minutes. Preliminary grout is held. For this, a plaster grater is used.

The plaster grid is stacked 100 mm.

At the end of the preliminary grout, the second layer of plaster with a thickness of 2-3 mm is applied. The surface is aligned and rubbed with a grater and half-tree.

If you need to stack your facade with decorative plaster, then the second layer can not be applied. He is applied only under painting.

Finish finish

The facade is discharged with decorative plaster and paint.

The wet facade will protect building structures, keep warm and decorate the appearance of your home.

Remember - the success of the work of work with their own hands depends on 30% of the quality of materials and by 70% of the correct technology.

In our country, two facades mounting systems were most common: hinged ventilated and so-called "wet". The latter are characterized by a simpler design, but preserve the excellent thermal insulation characteristics. The name "wet" considered type of facade received from builders due to the fact that it is applied various solutions and water-based compositions. The outer decoration in wet facades, as a rule, use fine-layer plaster. The resulting design perfectly copes with a changeable Russian climate and helps to significantly save on heating in autumn-winter period.

Remember that you can start any outdoor finish only after the building shrinkage (in the case of a new building). In addition, to build "wet" facade Specialists are recommended solely after completing the installation of the roof, decoration of rooms, installation of doors with windows, as well as all electrical installation works.

Structural scheme of "wet" facade

Let's start, perhaps, with flaws. The insulation of facades of buildings according to the technology under consideration requires a serious approach in compliance with the requirements for the ambient temperature and its moisture during the installation. In mandatory, all work should be carried out at a temperature of + 5 ° C and higher, with a low humidity level. Failure to comply with this rule can subsequently lead to fairly sad results, such as the disposal of plaster.

It should be noted that the construction of the wet-type facade is possible at minus temperatures. To do this, the facade itself is first covering special polyethylene filmand then start to pump under it air layer With the help of heat guns. The use of the film also helps protect the walls from dust with mud capable of leaving forever the trace on the dried facade. Thus, thanks to this simple reception, favorable conditions are achieved.

Technology "Wet" facade

But, despite all the existing restrictions, the facade systems of the "wet" type have many advantages:

• Guarantees high level Noise and thermal insulation at home.
• Allows you to ensure energy savings in the winter period by about 2 times. In addition, significantly increases the efficiency of air conditioning systems in summer time of the year.
• Allows you to shift the "dew point" to the outside of the building, which helps to achieve the most optimal heat exchange and avoid the accumulation of moisture inside the heat insulating layer.
• Promotes the formation of a balanced microclimate indoors due to ventilated external facade trim. This has a positive effect on the health of people living in the house, prevents the reproduction of pathogenic microorganisms and the emergence of fungal formations on the walls.
• Reliably protects the facade and carrier elements of the building of the building from negative influence Weather conditions.
• Mounting the "wet facade" can be installed on structures with any type of main building material.
• With this technology, you can make sealing seams in panel houses.
• Installation of the facade of the "wet" type requires smaller financial costs and allows you to significantly save on construction work.
• Thanks to a wide range of colors and textural solutions, the use of this technique allows you to implement a wide variety of design projects. And use modern technologies Application of finishing decorative plasters makes it possible to obtain truly unique and aesthetically exclusive results.
• "Wet" finish is easily amenable to both full and partial upgrade, repair and restoration. After many years, you can easily patch the facade in those places where it will be necessary.
• This type of installation significantly reduces the load on the foundation.

Comparison of the technologies "wet" finishing and mounted installation

Naturally, any technology in construction is not perfect and has its own characteristics. Since at the beginning of the article we pointed out that we are most popular with two facade installation systems, we will not extend their brief comparative analysis.

	Hinged ventilated facade	Facade system "Wet" type
Durability	Depending on the materials used, it may be stopped to half a century without the need for repair work.	Adverse atmospheric effects are able to lead to phased destruction of the external layer of finishing. After 3-5 years, partial repairs may be required. However, when using appropriate material standards and compliance with the technological norms, the "wet" facade will be calmly function and 25 years.
FEATURES OF MONTAGE	Installation of the mounted facade can be done all year round.	Requires a special temperature regime (\u003e + 5 ° C) and low humidity. During cold weather, installation work will be associated with excessive expenditures of time and means.
Service and facade service	The mounted facade can be easily and relatively quickly cleansed from pollution and dust.	Often, dirt with dust is entrusted inside the external layer of plaster, complicating the cleaning process.
Exposure to greenhouse effect	Thanks to the air ventilation layer inside the facade, the pressure drop occurs, which contributes to the removal of excessive moisture. This avoids the appearance of the greenhouse effect.	Errors in the process of selection of finishing materials are able to lead to the occurrence of the greenhouse effect. As a result, the plaster layer can begin to collapse.
Price	Installation of the ventilated facade costs quite expensive, but it is less soared in operation compared to "wet".	The facade of the "wet" type is cheap, but requires competent care, periodic cleaning and updates.
Scope of application	Used to finish structures with medium and large area of \u200b\u200bfacades. As a rule, these are urban structures: business centers, supermarkets, offices of firms, administrative buildings.	Perfectly established himself when finishing cottages, cottages and other buildings, which are erected outside the city feature.

Installation instructions

The process of finishing the facade of the "wet" type occurs in six main stages. Let's look at each of them in more detail.

Preparatory work

At this stage of work, it is necessary to estimate the foundation, on top of which all technological layers will be applied. The wall without finishing should first be cleaned of any contaminants present. In the event that the "wet" facade will be erected above the existing outer finish, before starting the installation work, check its carriers and agsell characteristics. If the facade is covered outside the material, which is inclined to absorb moisture, it is predefined to be well primed. It should also be carefully inspecting the external finish for damaged areas or surface curvatures. When such flaws are detected, it is necessary to fix everything, chopping them with a solution of plaster. In addition, before the start of construction work, the old plaster with the slopes of the door, as well as window Operactions It is advisable to remove in general.

Arrangement of the base profile

At this stage, we will need to install a profile plank. Its function is to ensure a more uniform distribution of the mechanical pressure generated by thermal insulating plates. In addition, the profile allows you to protect the lower row of insulation from moisture exposure.

Fastening the profile framework must adhere to the following recommendations:

• Metal profile must be located at an altitude of about 40 centimeters above the ground. At the same time, up to the plane of the floor of the insulated room should remain at least 20-30 cm.
• Before installing the profile using a thread, stretched between the buildings of the building by self-drawing, markup is performed.
• The profile must be attached strictly parallel to the ground, so the correctness of the thread tension and the correctness of its subsequent installation must be checked using a level.
• Between individual profile plars, you need to leave small gaps (about 3 mm) in which special connecting plugs insert. They are intended to compensate for the possible temperature expansion of materials.
• Fix the profile of dowels and self-drawing in a step of 20 to 50 centimeters. The choice of interval depends on the weight of the heat insulating material, which the facade will be covered. For light foam plastic, one fastener is enough for every half meter. But for severe mineral wool, it is necessary to place the attachment points much more dense.
• The decoration of the corners of the building is performed using a special angular profile or oblique cut. For stroke stupid and acute corners The profile bar cuts up accordingly.

Laying plates of thermal insulation

The insulation of the facade structures of the "wet" type is usually carried out using foam (expanded polystyrene) or mineral wool plates. Fixing and fastening of the insulation is performed using glue, following the next sequence of actions:

1. We apply a wide strip along the perimeter of the heat insulating plate of the adhesive solution, after having completed the edge from the edges of about three centimeters. Inside the formed perimeter also applied glue, a point method. Upon completion of this step construction solid Must be covered at least half of the entire plates of the insulation.

Note: If you use lamella mats for insulation, it is necessary to wear all the entire fastener with glue.

1. We perform fixing the plates. Starting should be started, starting from the base profile. Tightly press the heater to the wall treated with a solution, not forgetting during the installation process immediately remove any excess adhesive solution. Stay heat insulating layer The spreading method (by analogy with brick masonry) rows, that is, the joint of any two plates of the top row we have on the central line of the bottom.

1. We are waiting for about three days while the glue dries and proceed to the next step. Now we need to additionally fix the plates with spacel dowels. Their length should be calculated, based on the three main parameters:

• plate thickness.
• the thickness of the layer formed by the adhesive solution.
• the required depth of the entry of a dowel into the wall. This parameter depends on the type of the outer decoration of the wall. IN solid Wall It is enough to fasten a dowel on 5 centimeters, but the porous surface requires that the fasteners entered into it centimeters by 9-10.

Accordingly, the required length of the dowel will be equal to the sum of the above parameters.

Fixing insulation with plate dowels

The density of the location of the fasteners per square meter can also vary. Depending on the mass of thermal insulation plates, the diameter of the dowels themselves and the height of the range of the series, this number will be from 5 to 15 pieces.

1. Immediately before installing the dowel, the nest is drilled for it. The clamping bushings fix the flush relative to the plane of the heat insulating plate.

Installation of the reinforcing mesh of fiberglass

Between the completion of laying thermal insulation and the installation of the reinforcing layer must pass from one to three days. On top of the insulation, we apply a special adhesive solution, in which we will draw the reinforcing network of fiberglass. Start off this species The work should be performed from the corners of the building and the angular beeps of door and window openings. The recessed mesh after installation on top is coated with another layer of adhesive composition. The thickness of the resulting layer in general should be within six millimeters. The optimal depth of the mesh arrangement under the upper layer of glue, in turn, will be about one and a half years.

Conducting outdoor finishing works

Waiting for the complete drying of the reinforcing layer, the period of which can range from three to seven days, we can proceed to the next stage of work. Remember that the application of the final plastering layer requires the relevant conditions, namely:

• Ambient temperature from +5 to +30 0 s
• Low air humidity
• No influence of direct sun ray (work is better to carry out in a natural or artificially created shadow)
• Favorable weather conditions, lack of strong wind and atmospheric precipitation

Naturally, it is possible to achieve their implementation and artificially with the help of heat guns, the cover of the facade with a special film, but professionals are still recommended to carry out final work in the warm season.

Stucco for outdoor work should be chosen very carefully. From its quality will largely depend on the durability of the resulting finish.

Plaster must have a number of important characteristics:

• Excellent stealing.
• Moisture resistance.
• Strength, resistance to mechanical damage and atmospheric conditions.

Arrangement of waterproofing and decoration of the base part of the walls

Prior to the start of work on the arrangement of the base, it is necessary to perform waterproofing the adjacent area and the lower part of the walls of the building using the cabinet. The sequence of actions is similar to general Technology Finishes with small additions:

• Additional fixation of the plates of the insulation dowels is allowed at an altitude of 30 centimeters above the ground.
• The reinforcing layer of the base part of the wall is made double.
• The exterior decoration of the base is performed using ceramic or stone (including from artificial stone) Plates, as well as mosaic plaster.

Before you consider the question of the merits, you should deal with the terminology. The fact is that in many articles are the incorrect definitions of the wet facade, which is why inexperienced developers arises confusion. The amateurs are called a wet facade such insulation, which uses water-based adhesive. Once this material is "wet", then the facade, respectively, also "wet". For persuasiveness, they talk about the dew point (it, they say, in this case it is carried out beyond the walls) and the information acquires a "scientific" view. What really?

According to the currently existing construction regulations, all buildings must meet the requirements for heat saving. It is impossible to achieve this without using insulation. For example, even the wooden walls in the middle lane of our country should have a thickness of at least 60 cm, only such parameters guarantee the necessary thermal conductivity.

If the walls are made of brick, then their thickness increases to 120 cm and more. Of course, no one has such houses, and efficient insulation is used to improve heat surfactants, most often mineral wool or foam.

Warming can be done both internal and external surfaces of the facade walls. Let's stop by external surfacesThey are insulated in two ways.

As for the dew point, it is in all cases without exception, it is believed beyond the premises. The only exception is the walls of the house are so thin that the rooms are cooled to the dew point. Such cases are in old panel shrushchev.

We specifically took your time to clarify the terminology, only knowing this can be correctly understood the process of insulation of facades on various technologies.

Technically, such facades should be called a heat-insulating composite system of insulation of facade walls with outdoor plaster layers. As insulation, foam plates or extruded mineral wool plates are used, the thickness is chosen taking into account the climatic zone and the initial characteristics on the thermal conductivity of the facade walls. But in most cases you need at least ten centimeters. Extruded mineral wool use very rarely and only special species. The reason is insufficient indicators of physical strength, partial shrinkage during operation. What layers is the wet facade?

1. The base is the facade wall. May be brick, wooden, foam blocks, monolithic concrete or OSP sheets. The requirement - the surface must be smooth. IN otherwise Between the surface of the wall and foam plates will circulate air, due to this phenomenon, the effectiveness of insulation decreases at times.
2. Heat insulation layer. Foam polystyrene facade brands (non-combustible). Fixed with glue and plate dowels.
3. Flusket. It is desirable to acquire grids resistant to alkalis.
4. Ordinary under painting or decorative plaster. It is allowed to make the finish finish to make light facing facade plates.

Before proceeding with the description of the installation technology of a wet facade, we want to stay in more detail on the requirements for the facade plaster. The quality in this case is directly proportional to the number of years during which in the original form will be saved:

• facade integrity;
• his novelty.

So, it is best to stop the choice on elastic front plasters. Silicone compounds are ideal, for example, the plaster of the new generation "Coroed". Consider the main advantages of this facade coating.

Elasticity.Due to the presence of a flexible and elastic in the composition of silicone, "cored". Such properties of the coating prevent the formation of microscopic cracks on the dried plaster. This is an important quality, because any building after the end of construction work is subject to:

• vibrations affecting the structure in the process of shrinkage;
• expansion and narrowing materials from which the building is manufactured when changing temperatures.

All listed circumstances lead to the formation of small and frequent cracks on the usual plaster. The elastic silicone composition will be able to protect your facade from this trouble.

The texture of silicone plaster "Coroed", grain 2 mm

Moisture resistance.Another unique feature of the "Coroed" plaster from the Farbe plant is one hundred percent resistance to humidity and full vapor permeability. For this, you can again thank the unusual composition of the mixture. The finished plaster fits tightly to each irregularity of the wall covered, and creates protection, through which the water leaked is guaranteed.

Long color saving.As part of the plaster from Farbe, there are silicone resins that give the following effects:

• the surface does not fade - protection against ultraviolet rays is ensured;
• it warns the effect of any other phenomena affecting the loss of brightness of the facade.

If, as a result of the mechanical exposure, the plaster was somewhere scratched or lost, you will not even notice. All the mass of plaster is shocked in color and neither scratching or scratching are visible on it.

Self-cleaning.Thanks to the technology of "clean facade", the facing plaster "Coroed" is independently cleaned. This is due to the following factors:

• when distributing and frozen, the elastic composition forms a smooth, solid film;
• if there is even a small rain, the dust messengers on the facade is easily flushed off from it without help.

In other words, if you lazy to independently follow the appearance of the dwelling, and I would like "it yourself", the "Coroed" plaster from the factory "Farbe" is your option.

Record service life.The service life of the "Coroed" is on average five times higher than the indicators for similar goods presented today on the market. If using conventional plasterYou update facade coating Once every 5 years, with Coroned, it needs to be done once a quarter of a century.

Tinting.According to the manufacturer's statements, the Silicone Plaster "Coroed" that interests you is as much as 2,500 different shades. Such a variety is due to the use of computer tinting and pigments from leading global manufacturers.

Options for shades of silicone plaster "Cooked" Farbe

Little consumption.Dry plaster implies the consumption of material with a cladding equal to about 5 kilograms per 1 m². However, the product of the Farbe plant due to the quality and high density of the composition offers on the same unit of the area to use no more than 3 kilograms, which the cavity is enough to form an ideal coating.

The production of silicone plaster for facades is certified according to international Standard. By purchasing silicone plaster, you provide reliable protection to the walls of your own home.

Wet Facade Mounting Technology

Calculate the number of building materials with a margin of about 10%, prepare the tools. As a heater, we recommend using foam plates, it is the cheapest and very effective option. The lack of foam - the complete impenetability of moisture, but this will have to put up. Especially since brick or concrete surfaces and so hardly breathe.

For the finishing of the facades, forests will need, it is better to use metallic. If not - do yourself from sawnwood. Pay attention to the safety technique, set them on stable surfaces. Check the position in the level if the building has more than two floors, then you need to tie the vertical racks to the facade walls with special metal hooks.

Important. During the installation of forests, assign the gap between them and the wall, the size of the gap should provide convenient work with the hand during plastering or painting of the insulating layer. Otherwise, the forest will have to be dismantled and re-installed, and this is an extra loss of time and money.

Step 1. Check the surfaces of the front walls, the irregularities of more than 1 cm should be cut down, everyone else can be fired due to glue. Do not be afraid that the cost of work will increase. If you calculate the time for additional plaster walls, the price of materials, the use of glue as an aligning solution will be much more profitable.

Step 2. Special rope with blue sweep the lower horizontal line, make it in a strict horizontal position. If you are afraid that the first row of foam plates will go down, then the line should be fixed a flat wooden or metal rail. Bold it with dowels or nails, it all depends on the material of the manufacture of the facade wall.

Practical advice. Tarbed dowels must fit the ground, they have differences for wooden, foam blocks and brick walls, Keep this in mind during the purchase of materials. Dowels can be screwed into a tree or drive into a prepared hole. The length of the dowel should be equal to the thickness of the sheet of foam and glue plus about 60 mm on fixation in the wall.

Step 3. Porous surfaces should be primed, use the primer deep penetration. Apply the solution abundantly for maximum impregnation of porous bases. For smooth cement or brick facade walls, make a spray from cement milk. Such operations will increase the adhesion coefficient of glue with surfaces.

Step 4. Measure the deviation from the horizontal corners of the house and check the wall plane. You can do it with a plumb and rope.

1. In the corners of the house, install the plumbs throughout the height of the wall. At the top and bottom of the rope tie to a specially installed metal bar, tensioning it well.
2. Fasten the horizontal cord to the stretched ropes, do not tighten the nodes.
3. Gradually stretch the horizontal cord along the vertical ropes and measure the distance between it and the wall.

This data will be allowed to assess the status of the wall. If deviations exceed a centimeter, they will have to be elapsed.

Step 5. Prepare according to the manufacturer's instructions adhesive mixture. Quantity depends on your performance. During the preparation of a mixture into the tank of water, and then pour dry ingredients.

Practical advice. If the walls of the facade are covered with old paint, then do not rush to remove it, it is long and difficult. First, check the clutch strength with the base. To do this, ride in the paint a grid of a groove of about 1 × 1 cm in size, stick to the surface of the greasy tape and tear it off. If the paint remained on the wall - excellent, the insulation of the facade can be done on it. If not, you will have to remove from the surface of the walls.

Step 6. The glue must be applied to the surface of the foam. If the wall is smooth (irregularities do not exceed 5 mm) - use the ridge. But this happens extremely rarely. In most cases, the solution will have to be shifted by a trowel or a beacon spatula. One sheet should be up to eight lighthouses up to two centimeters around the perimeter and in the center, the diameter is about 10 cm. Due to this height, foam plates are easy to align. At the edges of the slab glue should be applied at an angle to prevent it in the seam.

Important. After one or two rows, eliminate the possibility of natural air convection between the insulation and facade wallOtherwise, natural traction will appear and insulation will be ineffective. Not just bad, namely ineffective, have it in mind. To eliminate traction, the solution on these stoves must be solid one line, the slot between the plates is completely absent.

Step 7. Immediately after spreading, apply the slab to the surface. Cress and align the foam with a long wooden half-line or rail, control the level.

Important. Inexperienced builders can deviate vertically, it is difficult for them to control the position of the level. We recommend to make a template from ropes. Tension them at the desired distance from the wall and lock. Ropes will need to be installed at a distance of about 2-3 meters. Such simple devices will allow constantly controlling the position of all foam sheets in the height of the facade wall.

The difference in the height of the planes of two adjacent plates can not exceed two millimeters. If deviations were found, then after cooling the adhesions, the protrusions need to be carefully cut into a very sharp knife and make the transition invisible. If there are wide joints between the butt plates - anything terrible, they will then be played mounting foam. The second and subsequent ranks are recommended to start from inner corners And move to the outer, the internal customized is harder.

Step 8. To increase fire stability of buildings between each floor, fire jumpers must be made. This requirement of new legislation is aimed at improving the safety and fireproof buildings. Fire litters are made from extruded mineral wool of the same thickness as foam plates. The width of the dissection is at least twenty centimeters. Jumpers are installed throughout the perimeter of buildings and windows and door openings.

Step 9. Finishing window and doorways. Remove the size of the slopes, cut the plates on them. Do not hurry, all the joints must be as smooth as possible. The insulation is better to use mineral wool, but the choice is yours. If the finish finish is relatively massive, then take the foam. The insulation must close the frame of the windows and the door, due to this decrease heat losses And the appearance of the facade wall is improved.

Important. In the place where the window sump will be installed, the foam must be cut off at an angle to ensure the unobstructed stack of water. One more thing. Stove seams should not be a continuation of slopes. In these places you need to use whole plates and make the appropriate cutout cuts in them. This method eliminates the random injection of water in the gap between the facade wall and the foam. The minimum allowable distance from the seam to 15 cm slopes.

On the part of the plate adjacent to window block, glue is not applied. In the future, the gap is fought by construction foam.

Get all the cracks with the mounting foam, after its cooling gently cut the remnants. Foam foam empties on the entire thickness of the plates, it is recommended to moisten the surface before the faving.

Step 10. After the final solidification of glue, fixation strength increase special dowels with large heads. It is necessary to install them in places of adjusting the corners and in the center of each sheet. We have already mentioned that no technology recommends mounting the insulation slabs without a dowel, no most expensive glue gives such a reliability of fixation as a dowel. For each square meter, the slab must be at least four pieces.

This is completed on this process of insulation, you can proceed to further finish.

Watching insulation

A very important process, not only the appearance of the facade wall, but also the durability of the entire finish depends on the quality of its execution. To increase the strength of the adhesion and protect foam sheets from mechanical damage, it is necessary to use a plastic mesh, the cell size is about 5 mm. Before starting work, check the surface of the wall with a long rule or rack.

Initially, it is necessary to separate the corners. Metal applies to strengthen the corners perforated profiles. Cut the grid strips of about 30-40 cm. Apply glue at the corners of the buildings of the same width, climb the reinforcing grid into it, align it. Install the corners metallic profile And again we climb it into the solution. Conduct the surface. From above, the corners will close the new mesh during the finishing of the facade walls.

Step 1. Apply a layer of solution with a thickness of a solid with a wide spatula with a solid metal grater or a wide spatula along the plates, immediately align it. There is no need to try, the main thing is that it is well glued to the surface of the foam. The glass was easier to lay down from top to bottom, the backstage must be made at least ten centimeters.

Important. Never apply the grid to a dry wall, and then smear glue, you only make frank halchiers. The fact is that this method of finishing significantly reduces the strength of gluing materials, further on the plaster there will be cracked. pay attention to finished housesMany of them have this disadvantage - the consequences of unfair masters.

Step 2. Thoroughly align the surface of the grid, the fibers must be completely covered with glue. Check the wall plane with a long rail and smoke all irregularities. To do this, carefully attach a flat rack to the wall and immediately take away. On the fingerprint of the track will be visible sections that need alignment.

The surface must be as smooth

Step 3. If the facade is planned to be painted, then the second layer of plaster should be applied, the thickness is in the range of 2-3 mm. The main condition is the maximum alignment of the walls. The technology is the same, do not be discouraged if traces remain after the spatula, then they can be carefully lined with an ordinary grater. If decorative plaster is chosen for the finishing finish, it is possible to apply it on the first layer. The same applies to gluing thin front plates.

If the base is insulated, then here you need to adhere to the recommended technologies to the maximum extent. The surface of the base should be placed, before gluing the plates, hesitate to soak the hydraulic displacement. The fact is that concrete absorbs a lot of moisture, it will fall on glue. And the foam excludes the possibility of evaporation, the water accumulates under it, during freezing it is expanding and the plates will fall off, they will only hold on the dowels. If the base is then placed rather heavy finishing materials, they deform their weight foam plates. At best, the surface will be uneven, at worst it will have to take the materials and repeat the insulation of the house first.

In the absence of experience of doing such work, it is difficult to find out whether the foam was secured reliably. We recommend to make a trial glue. Apply the solution around the perimeter and in the center, adjust the sheet to the facade wall and align its position. Immediately take the foam and look at the traces of glue on the wall. They should be uniform throughout the area, and the total area is at least 40% of the magnitude of the sheet. Such a simple test will provide an opportunity to further focus on the number and place of glue. In addition, you will feel with how the foam sheet should be pressed to the facade wall.

Installing a row always start with angle and with a whole plate. If the opposite corner does not fit the plate, then it should be trimmed in size and use the penultimate, and the latter should be a whole. In the extreme case, the spanning area of \u200b\u200bfoam should be doubled the area serving the corner of the house. Do not forget that the stove must be over the angle of the building on its thickness, in this place insulation from two walls should lie on the vents. Better make a protrusion with a margin, surplus will penetrate. A solution should not fall on the protruding part of the plate. The following rows of foam on the previous ones are installed in the gear gear. The more dense they will lay down, the more reliable the mount. In external corners, the largest load, and you cannot progress in the dowels, remember this and accurately perform all operations. The plates on the wall should be aimed, the coincidence on the wall of the vertical seams is prohibited.

Especially carefully check the position of the first row, it is he who sets the level for the whole wall. It is recommended to put the subsequent ranks only after complete rejection of glue on the first and fixation by his dowels.

Do not allow glue into the joints between the stoves. Why? Cement mixtures have high thermal conductivity and form cold bridges. They will become noticeable on the facade walls in the form of wet strips. There are cases when such disadvantages cannot be hidden even with decorative plaster. The bands are non-permanent, depending on climatic conditions appear or disappear.

The main task of the reinforcing grid is the protection of foam from mechanical damage. Experienced builders They know that it is impossible to clean the foam from dried quality glue without damage to the surface. This means that the role of the grid in holding the plaster is minimal. If the mass falls off, then the repair is still not avoided, the plaster will be saved on the grid. Hence the conclusion - reinforcement must be made in those areas of the facade wall, which may be damaged from mechanical effort, as a rule, not higher than 1.5 m from the base. All that is higher - to your personal discretion.

Cut foam plates can be cut with small teeth. But this is not the most good option. Much smaller cut after cutting heated nichrome wire. It can be bought in specialized stores, the length of the wire depends on the diameter. Tension the wire in a convenient location and connect to the outlet. Uneven cutting faces after hacksaw can be submitted by a special grater.

Extruded expanded polystyrene has a very low adhesion with adhesive compositions. Before use, be sure to clean it on both sides of the grater until the shallow groove appears.

Do not use this material as the main heat insulation, it can only be used to finish the base. And then only in cases where the finishing finish of these surfaces is made heavy materials.

Video - Wet Facade Mounting Technology

Frame house. But for outdoor work, in addition to the traditional design with a crate and ventilated gap, only one technology is used. We are talking about the "wet" facade. He received its name due to the technological features of the installation.

Features of wet facades

Finishing wet facade is a "pie" from several materials consistently laid on wall trimming or CSP. IN general It looks like this:

• a layer of adhesive composition based on;
• thermal insulation material;
• glue;
• reinforcing mesh;
• glue;
• facade plaster;
• paint (if necessary).

All these building materials are easy to use, so you can cope with the facade device on your own.

But is it worth choosing such an outdoor finish for frame house? Answer this question will help assess the advantages and disadvantages.

Advantages and disadvantages of technology

The wet facade is fundamentally different from the ventilated. This applies not only to the structure of the wall "cake", but also its operational properties.

To the advantages of technology You can attribute:

• Effective heat maintenance by minimizing the number of "cold bridges". In the ventilated design they are formed a large number of Fasteners of the crate.
• Saving finance and time.
• Aesthetic appearance at home.
• Additional insulation, high-quality sound and vapor insulation of walls.
• Lowering the load on the foundation.

Disadvantages of the insulation of the facade of the facade wet in the way there is also. They are associated with the conditions for laying materials, applying adhesive compositions. So, permissible air temperature In the process of operation, there must be no lower than +5 ° C, and the humidity is not more than 40%.

If these conditions are not followed, the likelihood is that glue and plaster will be sinking unevenly. This negatively affects the quality of the final coating, the period of its operation.

Wet facade materials

The competent device of the wet facade of the insulation, the technology of which is quite simple, is largely based on proper choice Materials.

The insulation is used by foam or mineral wool in the form of rigid plates. They prevent the formation of condensate, keep warmly well.

Wherein polyfoam loses Minvat According to the degree of environmental friendliness and flammability, but surpasses it by convenience in work, price, strength. It is also not subject to shrinkage during the operation of the house.

Note: when choosing slab insulation It is important to its thickness. It is calculated based on climatic conditions, insulating characteristics of frame walls.

For the reinforcement of the wet facade, the grid of fiberglass resistant to alkalis is used.

The best option for fixing foam - glue-foam in cylinders. It is also called liquid foam. It is quickly grasped, does not pass warm, resistant to moisture. The disadvantages include only a high price.

An alternative can perform universal facade glue in dry form. For the best adhesion, it is imposed by the primer of the same brand. But mineral wool is better fixed on a special reinforcing glue.

Wet facade device on a skeleton house

Installation of the wet facade of the frame house implies the consistent performance of a number of works taking into account the characteristics of the materials used. If you do not want to invite third-party masters, take care to have several reliable assistants.

Stage of preparatory work

The wet facade is a good solution for the skeleton house built from scratch. The walls of the wall, which is the basis for laying the insulation, has a smooth and clean surface. Its not necessarily even primer. However, some preparatory work Nevertheless need.

For gluing a layer of insulation, it is clearly distinguished by the surface of the base and walls. This is done using a special G-shaped profile. The short side (perforated) is fixed with a dowel to the wall, withsting a step of 300 mm. The long side serves as a support and limiter for thermal insulation plates, so there should be no less than their thickness.

Note: during the installation process the profile is aligned horizontallyusing the construction level.

Instructions for laying insulation

Except for a few moments, the technology of installation of a wet facade for foam and minorvate is the same.

A fundamental difference is to apply adhesive composition. Glue-foam on the foam is applied around the perimeter of the plates, retreating from the edges of 20-30 mm, and in the middle - point. On the plates of mineral wool, the reinforcing glue is applied with a solid layer with a toothed spatula. The point distribution of the composition is unacceptable due to the high weight of the insulation.

After applying glue, the insulation plate is pressed against the wall and clutch. First row put close to starting. Each subsequent fasten so that the joints between the plates were "rotary", by analogy with brick masonry. At the same time, the evenness of the ranks are verified using a construction level.

The foam sheets are pointed quite tight, but if the gaps are formed somewhere, they can be melted with adhesive composition or fill in the mounting foam.

After complete drying of glue additional fixation The insulation is performed using plastic plate dowels. Their length is equal to the thickness of the insulating material plus 55-60 mm.

Laying the reinforcing layer

Before mounting the reinforcing mesh, the shafts of the dowels and the building level are tested by the level of thermal insulating layer. After that, proceed to strengthen the corners.

Their surface is covered with a layer of glue, in which the mesh of fiberglass and a metal angular profile over it takes over. The glue is then uniformly distributed over the surface of the insulation. The optimal layer thickness is 3 mm. For work is suitable as a building grater and a wide spatula.

On the glue layer, the reinforcing mesh is placed in the bottom upward direction. In the joints of the junction of the canvas make a total of 100-120 mm. All cells must be completely recessed in glue, and irregularities are eliminated.

For finishing, the outer walls on top of the grid of fiberglass are applied another layer of glue. Its thickness should be 2-3 mm.

Finish finish facade

The finishing finish of the wet facade of plaster can also be performed with your own hands. To do this, the base layer of the glue layer is allowed to dry. Then a layer of primer, which improves the adhesion between the piston and basic coating is applied to it.

After grafting the wall also must dry. Depending on the solution used, it may be necessary to be needed 5-8 hours.

Facade plaster can be purchased both in the form of a finished solution and in the form of a dry mix that should be shuffled with water. Apply it with a layer, the thickness of which is about 5 mm. Nuances of working with concrete material manufacturer reflects in instructions for use.

The design of wall openings is one of the most difficult stages of work. And here it is important to pay attention to the following:

• For the purpose of fire safety around the perimeter of openings, there are lashes from non-combustible mineral wool. They must have a width of at least 200 mm, and the thickness is equal to the thickness of the main insulation.
• In plates heat insulating material Cut holes equal to the perimeter of discovery openings.
• Along the window and doorways, the insulation is better not to glue, but to blew the formed gaps by mounting foam.
• The joints of the insulating material should be at a distance of at least 150 mm from the slope.

Accounting for these nuances - the guarantee of the fire safety of your home and effective drainage From its outer walls.

Thus, the technology of a wet facade is a good solution for those who want to economically insulate the outer walls of the house without losing them in their aesthetics.

Warming and installation of facades in "wet" type with thin plaster

New look at the facades

The most commonly used structures of facades in Russia are hinged ventilated facades and the so-called "wet" facades. Wet facades, in contrast to hinged, have a simplified design, but at the same time adequately perform the function of the external thermal protection of the building. Wet facades are usually decorated with a thin layer of plaster. This design allows to operate the building in the changeable Russian climate, as well as save on heating and facing.

The definition of "wet" builders, contractors and consumers have been introduced into use because water and other solutions and compositions are used to build this type of facade. Unlike its ventilated female, this facade has putty, primers, paints in its design.

The indisputable advantage of the use of plaster is a wide range design solutions When embodiment modern projects And the finishes of the buildings "under ancient", because with the help of plaster you can create a variety of textures. And the color accents are placed with special finish paints for outdoor work.

The use of insulation on the outer wall of the building allows you to move the dew point from the inside. Thus, all internal structures are reliably protected from penetration of atmospheric moisture and precipitation, which, during freezing, contribute to premature mechanical destruction of materials and / or activate corrosive processes.

Buildings with outdoor insulation are not only more durable, but also much more comfortable for accommodation due to the savings of optimal temperatures in the interior. As well as less energy-cost during operation.

Preparation of facade to insulation

The construction of a wet facade is possible only with complete protection against minus temperatures and precipitation. This requires instructions for the use of building mixtures. If the facade with the insulation, covered with plaster, is built in an unfavorable time of the year (autumn-winter), it is recommended to build forests covered with wind pressure film and provide a thermal circuit.

Before you do a wet facade to close interior (roofing, windows, doors) and spend everything internal workassociated with the pouring of the screeds, the construction of monolithic walls, rough plaster plaster. On the outer walls, the necessary brackets for wastewater, video cameras, signs, air conditioners, sings and other are fixed in advance.

Of great importance is the preliminary preparation of the draft facade under the decoration. So the outer walls are rushing from old sprinkling coatings, washed thoroughly with water under high pressure and dried. Then the cracks are put off and align the surfaces in such a way that the error is not more than 10 mm per square meter. It is important at this stage to use putty materials and plaster compatible with the materials that will be used later.

Physico-chemical characteristics of the insulation

Two types of plates are commonly used as the insulation layer: polystyrene or mineral wool.

The polystyrene foam plates have high rates Heat shields. This is comparative inexpensive material. It is easy by weight, and therefore quite easy to install.

Mineral wool plates preferably choose basalt or diabase. The material should have sufficient gap strength (from 15 kPa and higher) and not to react with plastering compositions. In this regard, the use of fiberglass plates is completely unacceptable for the construction of a wet facade. Despite other positive characteristics, fiberglass does not have sufficient tensile strength, and also collapses under the influence of alkalis. Therefore, it will not only be able to resist the variable exposure to the impacts of the wind, but can also join the reaction with alkaline-containing construction mixtures.

The destruction of the fiberglass facade is inevitably under the influence of alkali contained in the base (reinforced) layer of mineral plaster and adhesive mixtures (the average pH of such compositions is 12.5 units). Usually the reaction enters into full force for 2-3 years, however, such a poor-quality facade may be collapsed significantly earlier under the influence of storm winds. Therefore, the first supply company recommends that it is fundamentally responsible for the selection of the insulation layer in the design of the wet facade.

We also recommend paying special attention to the density of the insulation of mineral wool. 90 kg / m 2 is a bar, below which should not be descended. Indeed, otherwise, difficulties will arise when applying the finish plaster, and the risk of separating too "soft" insulation in just a couple of years of operation increases sharply. The recommended maximum density of the insulation under the plaster is 180 kg / m 2.

Follow an important point When choosing a heater for a wet facade is the coefficient of moisture absorption. It should be very low (not more than 1.5%). This requirement is due primarily to the fact that absorbent water deform material, and also worsens thermal conductivity. Plates capable of greater moisture absorption cannot provide monolithization of the design, such a facade will not be able to simult more than 1-2 years.

All materials used for the construction of the MF should be selected so that the vapor permeability of the layers increases from the inside to the external trim. This design will make it possible to create optimal conditions for preventing condensate falling in the thickness of the wet facade. The climate in many regions of the Russian Federation is such that most of the time the temperature inside the room significantly exceeds this indicator outside. In view of which the risk of condensate falling sharply increases. The task of the builders to move away the dew point as possible from the inside of the building. After all extra moisture It has a big destructive force. Therefore, for the finishing decoration of wet facades, they use only those types of plasters that easily skip steam.

When installing plates of the insulation, it is necessary to strictly comply with the requirement for the inadmissibility of the error (difference in height) more than 3 mm for adjacent plates. Otherwise layer decorative plaster Will not be able to absorb this flaw. It is necessary to use either too thick layer of plaster, which is impossible by its instructions for applying, or to put up with the fact that the "face" of the building will be visible. In any case, this is a construction marriage.

As already mentioned above, cheaper and easy (by weight) insulation are polystyrene foam plates. This material is popular. The only argument is not in his favor serves the fact that polystyrene foam fuel material. However, there are special technologies that allow you to reduce this minus to almost zero. The processing of a special chemical composition (antipiren) ensures that the combustion process will be suspended, and the flame will fall down with a high degree of probability.

Another way to combat fire safety is the device of special dissection from non-combustible materials. This method is sometimes called even combined, because in addition to the main insulation of polystyrene foaming, mineral wool slabs are used for dissection.

The polystyrene insulation for the arrangement of the wet facade must have the following physical characteristics: tensile strength from 100 kPa and above, density from 15 to 25 kg / m 2.

The quality of polystyrene foam insulation is determined, including external signs. Separate granules of the substance must be approximately the same in size, their adjacent to each other ideally is quite dense. Otherwise, such a insulation will not only be problematic when installing, but during operation, most likely, it will become too much moisture. And this, as has already been declared, leads to deformation, reduction of thermal properties and premature destruction of the facade

The insulation plates must have the correct rectangle shape: allowable deviations of any measurement of not more than 2 mm per m.

Delta thickness polystyrene foam plates should not exceed 1 mm. A disturbance of the facial plane should not be more than 0.5%. Otherwise, it will be impossible to establish the upper structures of the wet facade without marriage, expressing both in aesthetic inconsistency and in the reduction of the service life of the entire structure.

Mounting insulation to supporting design

The thermal insulation plates are installed with the lining of the vertical junctions - like ordinary brick masonry. This principle is important to observe when removing the corners. Dense fitting of each other moth-mounted material is achieved by grinding the irregularities of the essay machine. If the width of empty joints still exceeds the permissible norm, they are filled with cut-off stripes of the same insulation. The outer corners of thermal insulation are mounted by the Van. Recommended thickness of overhearsow 2-3 cm. This allows you to align the external corners of the building and keep heat inside. Extra centimeters of the insulation are cut into a knife after complete drying of the glue.

In the wet facade system, the fastening of the heat insulating layer is carried out in two ways in two ways. Initially, the plates plant on a special construction glue, and then add dowels adding. It is such a two-stage mount that allows the design of the desired strength and immobility. The highest loads of the facade is experiencing under the influence of wind gusts capable of separating poorly fixed materials and lead to the formation of emptiness between the layers of the facade. In addition, thermal insulation carries its weight and facing plaster - this load takes on itself mostly dowel. It is the plate dowels that hold the weight of the wet facade design and provide a dense fit of relatively soft plates to the base. The adhesion of glue additionally gives the possibility of hanging the draft facade, the surface of which is most often not distinguished by perfect smoothness.

The time gap between the step of gluing and tightening the dowels is usually about 24 hours.

When installing thermal insulation plates in the places of door and window openings, they are customized in shape and size with a knife on the place of gluing. Wherein horizontal seam Between the plates should not fall on one line with slope.

Reinforcement

Reinforcement is carried out after strengthening plates with glue and dowels. It is necessary to give a completely dry constructions before entering the device of the reinforced layer. Thus, it is projected not earlier than a day after gluing thermal insulation plates.

The reinforcement procedure implies the application of the adhesive composition on the insulation, and the construction reynching grid is inflicted, the execution of the upper covering layer. The total thickness of the reinforced layer is 4-6 mm, while the concerning layer should be thinner than about 2 times, and the mesh itself should be located 1-2 mm from the surface.

Typically, a fiberglass (fiberglass) grid is used for reinforcement. It is still covered by special composition, which prevents the occurrence of alkaline reactions.

When the wet facade is erected on buildings experiencing increased loads, as well as base floors, it is recommended to use a stronger and rigid shell reinforcing grid. Such meshs are able to withstand large mechanical effects compared to fiberglass.

The quality of the reinforcing layer plays a very important role in the strength of the entire wet facade. It is this layer that should ensure the stability of the facade to the wind and other mechanical impacts. Therefore, the grid should be not only durable, but also resistant to the action of alkalis contained in plastering solutions. Properly selected grid is the key to the durability of the wet facade.

Reinforcement starts with the corners of the building, then give them to stand and dry out for 24 hours. After that, you can proceed to the reinforcement of other surfaces. Unlike insulating plates, which begin to mount the bottom, the reinforced layer is equipped, moving away from the upper levels of the structure to the bottom.

Two important rules should be remembered:

1. With adhesive compositions work in the shade or under cloud weather.
2. The reinforcing grid should not come into contact with thermal insulation, there must be at least 2 mm glue between them.

Finish

Over the reinforcing layer in the wet facade system uses plaster under further painting or facing with special materials. Before these finishing works, it is necessary to be established and dry the reinforcing layer for at least three days.

The quality of plaster and the duration of its operation will directly depend on what conditions this stage of construction was performed. Therefore, in the autumn-winter period, it is recommended not to carry out these works or build protective structures. After all optimal conditions are: air temperature from +5 degrees Celsius, shadow, lack of impetuous wind and precipitation.

Special facade plasters should be selected for outdoor work. Only they are able to take full load of adverse effects. Exactly upper layer Plasters should have sufficient steamwilling, moisture resistance, mechanical damage strength, resistant to chemical reagents and other influences of the natural and environmental medium. In addition, in the context of the Russian climate, these plasters must withstand minus temperatures, as well as frequent thaw and high humidity.

Doborny elements

The bearing base of the wet facade, as a rule, is a rather complex design, including many external and internal angles, window and doorways, connections with the roof and basement, and sometimes external decorative elements In the form of semi-colonne, stupid and sharp corners, rounded parts. Also special attention Requires deformation seams and places of adjoining the building to other buildings.

Window and doorways are constantly subjected to vibration and shock effects during the operation of the building. And the places of adjoining to the roof, the base, other buildings cause difficulties during operation during a change in temperature, since the expansion and compression coefficient under the influence of heat and cold in different materials differs significantly. Large in the area of \u200b\u200bthe facade (if at least one linear dimension exceeds 24 meters) require laying of deformation seams.

To solve these problems in the structure of the wet facade, special profiles are provided that can eliminate these adverse factors. These profiles are straight and corner. They are a polyvinyl chloride base with a fiberglass mesh and an elastic waterproofing membrane.

Let's summarize

Wet facades have a number indisputable advantages: They differ in the use of the most modern insulation materials, their service life of at least a quarter of a century, the features of the external finish (fine plaster) allow you to build wet facades for both the restoration of buildings - architectural monuments and modern construction.

In order for the facade to serve for many years and successfully performed protective and heat-saving functions, it must be certified. Important role Also plays selection of materials in many signs. First of all, they must be compatible with each other. Do not join unwanted chemical reactions, each subsequent layer must have greater steam conductivity with respect to the previous, supporting structures and materials should have sufficient strength and density. Also building materials for the wet facade should be responsible for fire and environmental safety standards.

Technologiststhe advantages of the facades on wet type

Saving heat, which means energy saving, and reducing financial losses, ultimately, is an important issue for most regions of the Russian Federation. Simple measuring work has shown that the greatest heat loss in panel and block houses happens just through the walls.

A couple of dozen years ago, this question was practically not solved. Today, with the propagation of wet and ventilated facades, you can provide highly efficient protection from the cold, placing the insulation outside the structure. Note that at the same time the dew point is not only shifted, but also the internal space is saved.

Design of buildings with a wet facade system assumes that the walls are separated by the heat saving function with this outdoor design. Thanks to this, you can now build thinner walls, which means to spend less material on them. Moreover, the "lightweight" thus walls create a smaller load on the foundation, which in turn now can also be less massive. But the foundation for experts is estimated to be one of the most costly elements of construction.

The use of modern high-tech materials in the wet facade system allows you to create a more favorable room indoor climate. Couples are free to outwardly, the condensate does not accumulate, which is so loved by mold and mushrooms, harmful to human health. The temperature indoors is aligned, there are no cold zones near the walls and windows. And in hot weather, the wet facade is capable of more efficiently maintaining coolness indoors, because the thermal conductivity of the design is minimal.

It is impossible to forget about the high sound-proof properties of the materials used. The wet facade significantly improves the soundproof of the premises, both outside and in the opposite direction.

A positive impact is also on the service life of the building, the safety of its walls, which are reliably protected by a wet facade from atmospheric and mechanical effects from outside. The facade protects the inner structures of the building from the wind, dust, dirt, frost, sun rays, moisture drops.

In addition to the above, it should be noted that the technology of the wet facade you can make a facing of a building for a wide variety of design projects, both for construction on an industrial scale and for private house-building.

The only relative disadvantage of the wet facade is that most of the work on its construction should be carried out under special favorable conditions: T +5 or more, the absence of precipitation and rigid solar radiation.

Repair of the facade of wet type with proper approach You can postpone 20-30 years. Cosmetic defects (wear of the upper plaster layer) will have to be carried out more often, but it does not require large financial and labor costs.
