The insulation of facades with a heavy method is made without the use of glue, the plates of thermal insulation are attached with hooks and dowels. They are attached to the wall, after which the material is mounted to provide heat insulation.

Also, installation technology implies the installation of a metal grid before applying the facade plasters.

The use of such technology requires an independent arrangement of the insulation from the wall. It is somewhat simpler, this kind of construction without much difficulty absorb various processes that are associated with deformation.

Moisture and the action of seismic activity will also not cause any inconvenience. The device of the wet facade of such attachment is called floating.

In addition, you should select the next moment: mask metal gridWhat is used in this technology by manufacturing and performing thick plaster layers, the width of which varies from 20 mm and up to 40 mm. Great cerepes as plaster.

That is why such a wet facade is called heavy. It follows from this that the need to prepare the surface of the wall to future warming is missing, which is its advantage.

It is important that moment that the insulation of the building wet method It is advisable to use only if the main components of the wall are brick, a cellular concrete or a clay-concrete block.

One of the substantial minuses of this technology is the price. Of this kind of insulation methods cost more than more expensive than the same light facadewe will tell about next.

Easy Mounting Wet Facade

Such a method of insulation is intended by one of the most accessible and lungs. The small weight of the design makes it easy to make installation.

The only basic requirement is equal Wall. Otherwise, it is worth carrying out additional preparatory work with the help of plaster.

The insulation is fixed to the wall using special plastic dowels, and the glue contains cement. This is a fairly rigid method of fastening the insulation.

The supporting structures of buildings do not carry the tasks to ensure sufficient thermal protection of the premises. Brick, slagoblock, tree, reinforced concrete panels Or the monolithic elements of the fence can not withstand the requirements for this parameter. Therefore, they need additional processing insulation.

This is one of the methods of lightweight insulation, which allows:

1. Add additional thermal protection to wall panels.
2. Increase the heat saving of the premises.
3. Give an attractive appearance to the building.

The fundamental system of the Wet insulation device using the "Wet Facade" technology

The outer decorative layer is the plaster, thanks to which the facades acquire attractiveness. Insulation facades wet method It assumes the use of thermal insulation. The list of layers of the system from the inner to the outer looks like this:

• actually wall;
• glue composition;
• insulation;
• reinforced starting plaster layer;
• decorative finish plaster For outdoor work.

The main advantage of the technology is that wet facade can be mounted in any climatic zones. Minus - work should be made at temperatures ambient At least +5 0 С and no more than +30 0.

In the cold period, the place of work should be heated and hidden from the environment by the Shatter. The wet facade This technology is referred to because binding substances are binding to water and at the time of application are wet.

What insulation are used in the wet facade systems?

Glasswater and minvat are categorically prohibited. It is associated with insufficient strength of these insulation. They are not able to withstand a lot of plaster. In view of this, they are prone to resolving. Polyfoam is also not included in the number of thermally insulation.

Typical insulation for wet facade - polystyrene foam and basalt wool

By mounting the wet facade with your own hands, involuntarily asked the question "What thickness should the insulation?" Construction market It is represented by a wide range of basalt wool with different thickness (from 2.5 to 20 cm). Among the proposed need to choose the one that will fully satisfy the requirements. If there is a project available, then in it this parameter must be specified.

If the work is performed without project documentation, then the climatic conditions of the region must be taken into account. The indicator of the total heat transfer parameter can be found in reference books. The help of a climate map of the Russian Federation, which is easy to find on the Internet.

It is necessary to compare the indicators of the resistance of the material heat transfer wall panels with specified numbers on the map. The difference must be compensated for insulation. When calculating, you need to consider and characterize outdoor plaster. Too overestimate the indicators of the warmed structure is not worth it. The balance of humidity and temperature must be respected.

What else will required in addition to the insulation?

Full list essential materials as follows:

• glue for fastening the insulation to the wall;
• aluminum profile;
• dowels for fastening profile;
• plastic dowels for fixing the insulation;
• insulation;
• primer;
• plastering arms;
• dowels for fastening insulation and arms (plastic);
• starting plaster (basic);
• finish decorative plaster.

Tool kit for a wet facade device

In addition, devices will be required:

• perforator (for concrete, brick, reinforced concrete panels);
• drill (for wooden walls);
• screwdriver (for screwing the dowels);
• special spatula for applying glue;
• set of spatulas for overlaying and smuggling plaster;
• containers for mixing construction mixtures;
• nozzle on a drill for mixing;
• brushes for stripping a wall surface before applying glue.

Perform works on your own, but for this it requires elementary construction skills and routing on the device of the insulated facade on the "wet method". This is especially true of plastering.

Work on insulation wet facade gradually

Step-by-step instructions of the wet facade technology looks like this:

1. Preparation of the wall surface.

   

   Grinding of insulated walls - an important stage of surface preparation

   This procedure involves cleaning the surface from any existing contaminants. In addition, it is necessary that it be smooth. Maximum difference On 1 m 2 of the area should not exceed 1 cm. Rights, sinks should be aligned with plaster. If the wall has places with swept fragments, you need to use the fastening soil. Primary preferably the entire surface. This will serve for the wall of additional protection.

2. Installing the base profile.

   

   It will perform two functions: levels and node taking the load of the upper plates of the insulation.

3. Applying glue.

   

   This procedure is performed by a special gear spatula. The adhesive composition is applied on the plates of the insulation, not on the wall.

4. Gluing.

   

   The procedure is performed from the bottom up belts. Plates located above the base profile must rely on it. When the door and window Operactions, Plates should be glued so that the opening angles are located within one solid slab. For this, there are special cuts in the insulation.

5. Fastening the insulation plates with plastic dowels with a wide hat.

   

   Work is performed after complete drying of the glue.

6. Apply the base plaster layer, 3-5 mm thick.

   

   The key stage of the wet facade - applying a plastering layer with reinforcement

7. Laying the reinforced grid. Work is performed before setting plaster. It is important that the grid is recessed into the plaster layer.
8. Alignment finish plaster.
9. Painting.

   

   Finishing Stage Finishing - Surface Coloring

Armed with knowledge, materials and necessary technical Inventory can be started at the installation of a wet facade.

Heavy and Light Wet Facades

There are two varieties of wet facades:

Heavy wet facade is used in seismic union zones, as well as in cases where thermal deformations occurring during the temperature differences are required. Thanks constructive features, Plaster remains holistic (not cracking).

But there are cons. Such is high compared to the light facade cost. It is associated with the fact that the amount of consumed plaster may increase at times, since its thickness of its layer can reach 20-40 mm. The army also pulls the rise in price, because it must be metallic, unlike a light wet facade, where polymer materials are used.

Another minus is a big weight. If the building is dilapidated and subject to reconstruction, the use of a heavy facade without special strength calculations may result in collapse. For most cases, a lightweight system is suitable. Moreover, companies are now present on the market, which can comply with high-quality materials.

Wet Facade Cerezite - Popular System

Brand Mark Cerezit has developed a complex of products for mounting facades on the technology of wet. The complex includes all components of the insulating cake:

• glue;
• military insulators based on Minvati or polystyrene foam;
• plastering mixes.

Those who decide to take advantage of the unified system of the wet facade of Cerezite, do not have to check the components of incompatibility. All components were developed with a loan to this parameter. Moreover, each component complements the functions of another and compensates for its disadvantages.

Let's sum up

Based on the above, it can be seen that the technology of the wet facade remains the most reliable and best way Heat the building. Having a description necessary actionsEveryone can independently perform work and make the house warm, cozy and beautiful outwardly.

You can insulate the walls of your home both from the inside and outside. But the wedding owner will always give preference to systems with the outer arrangement of the insulation. Vault of the SP Rules 23-101-2004 "Design of thermal protection" It says: "It is not recommended to apply thermal insulation from the inside." In addition, in favor of such a decision, you can also be called at least three arguments:

The "Wet Facade" method implies the following stages of work:

1. Preparatory process.
2. Warming of walls with mineral wool or expanded polystyrene from the outside of the structure.
3. Application to the surface of the insulation layer of adhesive mixture, followed by styling onto it reinforcing, alkalic fiberglass mesh.
4. Watching the surface.
5. Finish layer finishing material.

Externally, "wet facade" in the photo looks like this:

Warming facade on the "Wet Facade" technology

About the technology of laying this method of insulation you will learn a little later, and in this section I would like to mention his advantages and disadvantages.

The effective method of "wet facade" has established itself as one of the cheapest inexpensive facades in the "top 3 inexpensive facades", this can be found in the article, therefore it is used everywhere. But for the listed benefits of you only pleased, it should be done by technology, choose qualitative material And observe the necessary conditions When performing work.

Types of facades and their scope

The "wet facade" is a plastering finish, which is used to insulate administrative-household structures, residential buildings, office, commercial and industrial buildings. This type of facade is suitable for both low-rise and high-rise construction.

The outer walls of the structure can be insulated in two ways. One of them is called "Dry facade", And the other - "Wet facade."When the device of the first type of cladding disappears the need to use various solutions and compositions having liquid consistencies. To such a type of finishing facades include all types of ventilated facades, learn about which it is possible in the article ". Due to the existing space, the insulation is ventilated, the material is not moistened.

As for the second method, the "wet facade", or wet facade plaster, has nothing to do with moisture. The name implies that the heat insulator will be mounted on the wall, and then the surface with special solutions is plastered.

During operation, plastering and adhesive compositions are used, which are diluted with water, so the method is called "wet facade".

Classification of facade systems having outer thin plaster layers GOST R 53786-2010 "Facade heat insulating composite systems with outdoor plaster layers. Terms and Definitions",presented in Table:

Technology of the device "Wet facade"

All technological phases are performed at a temperature of at least + 5 ° C and not higher than + 25 ° C according to SNiP 3.04.01-87 "Insulating and finishing coatings». The quality of work carried out and the service life depends on the accuracy of the conditions.

Violating the temperature regime and using materials that are not intended for the "wet facade" system, you risk getting a cracked coating or a creased plaster.

Do not forget about your safety, because work will be made on top. Most likely, you use forests, according to Snip 12-03-2001 "Safety in construction" Part 1their installation is performed on tiers, and the height of each tier should be at least 2 m. The step, depending on the height, can be a multiple of 0.5; 1 and 2 m. From the outer plane of the forest walls are set at a distance of 300-400 mm.

Preparatory work

It is necessary to start work with an inspection of the surface and visual determination of its strength and carrier ability. If there are influx on the wall from the solution - we remove the excess with the help of the hammer or the other undergraduate tool, and the cracks with a solution.

According to standards Snip 3.04.01-87 "Insulating and finishing coatings" The base should be durable, rough, pure and having open pores. More than 10 mm drops should be eliminated.

Suppose the wall has a small portion of 200 x 200 mm, concave on a couple of centimeters, and if you close it with insulation, the emptiness is formed in this place. A random blow to the finished facade in this place will prolomit the insulation. Laying the plate on the discovering places is also fraught with an internal defect material.

If, by spending the palm on the surface, you saw a "chalk track" or from the wall something like small sand rolls - clean the wall more thoroughly. Sometimes you have to fully stucked the base.

The treated surface can be cleaned from dirt and uploaded by a special composition called "Primer", this intermediate layer will improve physico-technical indicators of the base. We do it with a roller or a wide painting brush.

Primer for foam should be applied only for foam, and not for mineral wool plates.

If the surface strongly absorbs the composition, then we apply a soil 2 times. This operation will increase the adhesion of the base and reduce the delaying of water from the adhesive mixture.

Installation of insulation

Using the "wet plaster" method, it is necessary to understand that most of the load will have to lay the insulation layer. We offer a drawing on which the design of this technology is clearly visible using decorative plaster as the finish layer.

"Wet facade"

Therefore, the choice and installation of the insulation material to the wall surface is a responsible torque in the "Wet Facade" device.

The selection of the material used in the work depends on the following indicators:

The technology of manufacturing works on the "wet facade" device allows the use of a synthetic polymer group of insulation, mineral thermal insulation materials and their combination. Materials must match Gostam: 10140-2003. "Plates of heat-insulating from mineral wool on a bitumen binder. Technical conditions", 16136-2003" Plates are pelitochitume heat-insulating. Specifications ", 22950-95" Plates mineral wool increased rigidity on a synthetic binder. Technical conditions. "

The thickness of the heat insulator is chosen depending on the existing standards of heat engineering of buildings and structures that are registered in Sniped 23-02-2003 " Heavy protection buildings. " It says that for the insulation of facades for residential premises, polystyrene foam, having a thickness of 10-250 mm or a mineral wool plate 25-180 mm, should be used.

Having taken to work extruded polystyrene foam, which has a smooth surface, should be made by Her Shhawa. To do this, you can buy the factory shutter for aerated concrete, as in the photo, or make homemade plans of metal profile, punched nails.

To work, purchase the tools necessary to perform the construction process:

• building level;
• a hammer;
• perforator with nozzles under a dowel (most often D8);
• electric drill;
• cutter for profiles;
• spatula: 80-100 mm and 350 mm;
• capacity for the dilution of adhesive composition;
• construction mixer;
• toothed culma, the size of a tooth is 8-10 mm, stainless steel;
• smooth edge of a smooth edge;
• grater with sandpaper or with a grid;
• long wooden seaterary;
• wide brush, roller for primer surface;
• construction knife for cutting the grid;
• polyurethane grater 300-400 mm for the formation of a structure.

Approximate consumption of materials is indicated in the table:

The fastening of the insulation begins on the base of the building to its roof, within one vertical capture, and is performed in the following chronology:

1. Fastening the base profile of the insulation layer from mechanical damage is protected using a base profile, which is installed above the base at 400-600 mm using a level. He also keeps the lower (first) range of the insulator, and the profiled dripper takes the rain drops. The base profiles are suitable for different thickness of thermal insulation material, they correspond to GOST 22233-2001 "Profiles pressed from aluminum alloys For translucent enclosing structures. Technical conditions »and the stove in them should accurately enter - without gaps. In the wall we drill holes for the dowels, at least 3 pcs per 1 m profile. We lean your profile to the wall, insert plastic dowels into the holes and drive into the wall with the help of a hammer. Sometimes the lining washers from polyethylene for lining between the profile and the wall are used.
   

   The location of the base profile in the established form should be on one line, in the locations of the connection are not provided for adhesive or deformation of the part.

   When the profile continues along the adjacent base, it is cut off at an angle of 45 °. In houses with cellars and technical underground, polystyrene foam slabs must overlap the slab ends are no less than 200 mm from the lower marker overlapping the first floor and the basement.

   

2. The coating with a glue solution of the surface of the insulation that the polystyrene foam is suitable for you to work better, you can learn in the article "", and for its installation we use adhesive mortar to cement basedBut only for outdoor work. The cellery solution is prepared manually using the construction electromyxer. How to do it, written on the package. Fill the tank with water in the amount of 5-5.5 liters per 25 kg of the mixture and slowly pour out a dry solution from the bag, thoroughly stir the content on low revs. There should be a homogeneous mass, it is left for 10 minutes, and then again stirring. The box should be mixed up to a homogeneous mass without lumps and remember that it only saves its properties for 4 hours.

   We apply an adhesive mass on the plate with strips of 30-40 mm wide at a distance of about 30 mm from the edge, so during installation it is not extruded behind the edges of the material. In the central part of the slab we apply about 6-8 slides, a thickness of 30-40 mm. The amount of solution is selected in such a way that a large half of the insulation surface has a contact with the base through it. The band of glue along the contour should have breaks, they make them with a spatula, thus excluded the formation of air traffic jams.

   

3. The gluing of the insulation to the base of the glue application immediately apply the slab to the wall, the long side of which lies horizontally, fixing it with a fist through the long wooden seach, or with the help of a color. In this case, control the vertical and horizontal position of the plate level. Glue, squeezed behind the contour of the insulation, immediately remove.
   

   You can not press the heat insulator to re-either shift it even in a few minutes. If it is incorrectly glued, carefully pull it out, remove the solution, only then re-apply the mass on the stove and press it to the surface.

   Plates are placed in horizontal scheme, Bottom up, keeping the chess location of the order of the seams, and at the corners of the "Vangest". At the corners we use the "gear" engagement.

   First, the stove is stacked with the corresponding protrusion on one wall, and then another is applied to it. The band that remains is cut off.

   Sews vertical and horizontal should not be more than 2 mm. If it came out that they are much more, you can not completely fill them with a solution. In the gap, you need to introduce a narrow strip of the insulation and pressed into the seam, no longer using the glue composition. When the gap is small and you can not insert heat insulation material, experts recommend to expand it and insert the insulation with effort, but without applying adhesive solution, but using mounting foam.

   To lay the glue on the insulation, it is better to use a toothed grater, such a method ensures the cleanliness of the joint and provides a uniform fitting of the insulation to the glued surface with the ability to level the sheet along the plane.

   Warring slopes outside, we use a heater with a thickness of at least 30 mm. The polystyrene foam plate is cutting with a width of 5 mm less than the width of the slope, or before gluing it from the insulation, we cut the wedge (8-10 mm) and fill the gap between the insulator and the silicone mastic frame.

   When insulating slopes, the plates must be per capita for 10 mm, so it is very convenient to poison the main facade insulation.

   In the corners of the slabs are mounted with the dressing of the seams. It should also be paid to the adjoining of the thermal insulator to the underpants the undercover, because this place is particularly demanding protection from mechanical impact and ingress under moisture plates. To do this, the edge of the heat-insulating material is strengthened by another layer of reinforcing grid, as for window and door openingsThe insulation of the layer on top is protected by a cornice bar.

   

4. Alignment of the surface of the insulation and the irregularities of the glued insulation, you need to cut the rubber with sandpaper. It is done only after rejection of glue, after 2 days after the stoves are glued. The grater should make circular movements with a slightly pressing.

   

5. Fastening the insulation to the wall of dowelismism of 2 days, when the glue was already grabbed, proceed to fasten the insulation to the base mechanically - special dowels with wide hats. We choose a plot and perforator drilling holes in it by a row of Ø 10 mm depth 15-20 mm longer than the length of the dowel. Otherwise, the garbage creaked in the hole will not allow to drive the tip. The length of the fungus is calculated according to the following scheme: the thickness of the heat-insulating material is + 10 mm (the thickness of other layers) + 40-50 mm into the wall. Suppose if the insulation is 50 mm thick, then the length of the dowel will be 110 mm, i.e. 50 + 10 + 50. The length of the hole will be 130 mm: 110 + 20, it means the length of the boraxy is a little more than 130 mm. The holes on the sheets: in the joints and in the center. A total of 5 fungi will go to the sheet. You can more if necessary. Regardless of the location of the dowels on the plates within the same plane of the section of the sheets are nailed from 50-100 mm from their edge. Now in a dowel, drive spacer tips, if they are difficult to score to the end - pull out a dowel, deepen the hole and score a tip again.

   It is worth remembering that a dowel with a thermal head should be purchased for work. Otherwise, on the facade with time they can perform rusty spots. Metal dowel rod itself, its spacer area is in brick masonry Or concrete, therefore, the metal rod is a cold bridge and can be rusted over time, and the thermal head will protect the facade from such a problem.

   

A properly reinforced dowel is considered when its head is in one plane with thermal insulation material.

If you need to put two layers of the heat insulator, then the first layers do the same as described above, and the second glue to the first, but in such a way that the joints overlap. After the surface grouting, you can clog the dowel, only correctly select the length of the product so that it is enough for the thickness of the insulation and the base.

In the case when the thickness of the insulation in two layers is larger than the existing fastener length, it is recommended for fastening to use mounting glue for expanded polystyrene. If you use an ordinary mounting foam, you can not achieve a smooth surface, because Expansion of foam is much more expansion mounting glue For expanded polystyrene.

Plastering on insulation

Before plastering expanded polystyrene foam, or another insulation, it is necessary to perform a number of operations that can be divided into 3 stages:

• Reinforcement of the surface
• Plastering
• Finish finish

Reinforcement of the surface

The "wet facade" technology after mounting the insulation obliges the next stage to reinforce the surface. This function is performed by a fiberglass mesh, appreated by a polymer composition to protect the material from alkaline corrosion. According to GOST P 537862010 "Systems of facade heat-insulating composite with outdoor plaster layers"reinforcement occurs by its "consuming" in the base composition during its application.

The fiberglass grid is a material of industrial production, in which the threads are fastened in perpendicular directions and form cells. All products must match GOST R 55225-2012 "Fiberglass grids Facade reinforcing alkali-resistant. Technical conditions. "

A fiberglass mesh is suitable for operation with a density of 160 to 220 g / m 2. The minimum is registered in technical regulations Famous manufacturers of facade insulation systems: KNAUF in "System outdoor thermal insulation Knauf-Warm Wall, "Ceresit WM thermal insulation systems. Buying a low density material, the developer reduces the reliability and strength of its facade against the tensile forces in the plastering layer.

Also, the grid will serve as a reliable basis for the next layer of plaster. If you bleach the material that does not meet the requirements, then alkaline solution solvents the grid for several years.

Such material reliably protect the facade from cracks arising under the influence of the temperature difference.

On the grid there must be a mark "for external, facade works". According to GOST R 55225-2012 "Fiberglass grids Facade reinforcing alkali-resistant. Technical conditions »Marking the product should be on each roll. By type, depending on the destination, the front fasteners are:

• private - P;
• reinforced - y;
• architectural - A.

The marking of the mesh for the facade (FS) includes: the abbreviated designation of the product, its type, nominal mass and width, the discontinuous stretching force based on and duck, the designation of the normative standard.

An example is this marking: FSER-160 (110) -2000/2000 GOST R, where

• FS - facade mesh;
• P - ordinary;
• 160 - weight in grams;
• 110 - Length in cm

• 2000/2000 - discontinuous efforts based on and duck equal to 2000 N;
• GOST R - Standard.

To secure the mesh, a layer of the adhesive-plaster mixture is necessary, in which a fiberglass mesh is lying, which serves as a base for high-quality plaster. It must correspond GOST P 54359-2011 "The compositions of adhesive, basic plaster, equalizing, putty on a cement binder for facade heat-insulating composite systems with outdoor plastering layers". To perform this stage, it is better to embark on 72 hours from the moment the heat insulator is glued to the wall. Remember that it is necessary to do this not in rainy weather and air temperature is not lower than + 5 ° C and not higher + 25 ° C. Do not leave the thermal insulation material without covering more than 2 weeks. If it still succeeded, then before performing the reinforcement, check the quality of the material: the yellowed plates, with a dusty surface, clean the grater or branch. We start working with complex sites - these are corners and slopes.

Reinforcement of corners

To work, we need a corner of plastic, as it is chemically inert, and the cement solution that we use has an alkaline environment. In addition, polymers are practically not corrosion and easily cut.

Profile marking: UP C-10 x 15 x 2500 is decrypted as follows:

• UP - corner profile;
• C - mesh;
• 10 - width, in mm;
• 15 - Length, in mm;
• 2500 - Length, in mm.

Work start from the corner of the building. It means that they need them, both internal and external, put in order - install ready-made perforated plastic corners with a grid, are available on sale, we talked about them above. The figure shows the scheme of their location.

Do not forget that it is necessary to set the angles professionally, and the insulation is laid in terms of the level using the "Rules" and thread. Corners pressed to the insulation and, using the level, exhibit them horizontally and vertically. The glue protruding through perforation, which was applied to the surface in advance, smoothed, with its help the corner is aligned and fixed.

The process itself occurs as follows: we apply a spatula (200 mm) solution at an angle (50-70 mm on each side of the angle, with a layer thickness of 2-3 mm). Apply plastic corner At the angle of the structure, add it to the surface and the spatula on the grid smoothed from the corner to the side, slightly down. It turns out an angle, on each side of which 50-70 mm is glued, and another 50-70 mm grid for pure insulation.

If there was a situation that you need to connect together two angle, we connect them vertically, just do not forget that the joint should be topped with the reinforcing grid, at least 100 millimeters.

Reinforcement of door and window openings

With the help of the level again check the slopes and if necessary, hang them with a grater. Install the pricing profiles with the grid. In the diagram you can see already ready design Window opening.

At the slopes, we apply a layer of solution, the profile grid is stretched, he charged into it and smoothes. We do so around the perimeter of the opening. Next, on the corners of the opening, we mount the corner and the bottomhole profile with the glass wall. A slightly more solution is applied to the corners, so that air cavities are not created under profiles, and the excess solution will be released through perforation. Do not forget to correct the profile to control the level.

It turns out that one mesh comes to another, they are inserted into the solution and on all 4 angle of opening at an angle of 45 0 we apply "Kosynka" - a piece of the grid. Externally, it will look like this:

Location "Kosinki"

At the corners of the openings, voltage and "Kosinki" are created prevent the appearance of cracks in these places. This section of the work is also performed as the previous ones: the solution is applied to the surface, the grid is applied, it is inserted with a spatula. Only "Kosynka" must be treated with force, remove all excess adhesive mixtures so that there are no thickens on the surface.

When the slopes are processed, the internal corners need to glipulate the strips of foxes, which in width will be equal to the width of the slope, and in length will be 300-400 mm.

Fastening the reinforcing grid to insulation

We begin to move from above from the left corner of the site, then down the diagonal movements in the direction from the center on the sides. From the bottom of the extension of the grid length at the level of the base profile.

Apply glue you need a spatula, not less than 350 mm. The smaller tool is applied to the mixture on a large, stretching it along the entire length of the tool, and apply a solution on the insulation. Well done "Ceresit" well. The layer must be 2-3 mm. Work should be produced small sites: 90 cm in width and in a height of about one meter. If a mesh is 1 m in a roll, then we capture 90 cm and 10 cm remains clean without a mixture, for the joint.

In height, we proceed only meter: with solar weather, the solution dries quickly, and you need to have time to apply it, put the grid, add a solution and stroke the surface with a spatula.

Mesh apply so that the width of 100 mm lay onto a clean section of the insulation. The spatula is smoothing the site from the center to the edges, down to the mesh "Vliple" evenly into the mixture. Ideally, when it is completely in a mixture, but almost visible her outlines.

The grid is sold in a roll, it is necessary to make a mesh strip from top to bottom, without cutting, and shoghes only the vertical seams. Starting from above to make a height of 1.5-2 meters, go down and finish work.

The principle for docking seams is the same both by the vertical direction and horizontal. We leave 100 mm mesh without a solution, it simply lies on the thermal insulation material. We embroider the next site (with a clean band capture), we apply a grid with an overlap 100 mm and spread the plot with a spatula. Thus, we get smoother and smooth on top of the seams.

The grid must be tightened well, position in the middle of the adhesive layer, it should go to the surface and its drawing should not be viewed.

In case the grid did not stretch and turned out bubbles or folds, it will have to cut it and with an adhesive 100 mm, along the edges of the cut, stick a new grid.

Remember that you cannot glue the grid by laying it on the insulation, which is not treated with adhesive composition. With a thin reinforcing layer in places, cracks will be shown on the plaster. Also, the deformation of the surface may be related to the fact that the reinforcing grid was laid without adhesion or unevenly recessed in solution.

After drying the adhesive composition, the surface must be primed up with a plastering layer (2-3 mm). It is chemically separated by a plaster layer from reinforced, reduce the absorption, and increase the adhesion of the finishing material. Be sure to make sure that the ships of the dowels are hidden, and reinforced layer grabbed with his head.

Finish finish

"Wet facade" against outdoor decoration At home gives a wide choice. Traditionally, this is: textured plaster, Coroed, under the "fur coat" and painting.

But after the surface of the reinforced layer of the facade is dry, it must be seized. For this, a plastic grater with a sandpaper nozzle is suitable. Movements must be circular, counterclockwise, with a small effort. Capture the plot is not big, the distance of the elongated arm so that it is convenient to work with it. Then, on the surface, we carry out the operation of dusting and priming.

Materials for the finishing layer "Wet facade"

The decorative coating should not reduce the vapor permeability and hydrophobicity of the protective layer, which means that we choose materials that correspond to such indicators as:

• high vapor permeability;
• resistance to water and unfavorable natural factors;
• strength.

It is not enough to prepare the plaster mix for the facade, since the use of a publicly available sand and cement-based solution is not enough. Special components and additives are needed here. There is a facade plaster on the foam, its counterparts, mineral wool. More details about the materials can be found in the article "We find out what kinds of facades and for which houses are used: stone, wooden, plastered, translucent, composite."

It is worth remembering that mixtures of different manufacturers are better not to combine. Famous manufacturers They offer their sets of materials, where must be included: adhesive and plaster solutions, primer composition, paint for the facade, fastening parts. Each composition is selected in such a way that the best combination of the properties of strength and durability is ensured.

For work only apply special compositions For outdoor work. More about them can be found in the article "Facades", here we will tell about plastering mixtures for certain types of insulation.

Plastering foam outside can be:

• mineral mixtures;
• acrylic compositions;
• silicone solutions;
• silicate plaster.

The solution for finishing the foam, polystyrene foam or foaming should be specialized, intended for working with synthetic insulation. And remember that prices different manufacturers Significantly different, but choose high-quality material, since the strength and durability of the coating depends on this.

The thermal insulators of Penoplex are considered to be the most effective of all existing ones. Thus, according to the results of 2011 (the company's data), the share of their products in this segment in the domestic market amounted to 52%. And in May of the past, 2015, in Novomoskovsk the launch of the first domestic and fourth production line in the world with a capacity of 550,000 m 3 of thermal insulation per year.

However, the material is exposed to external factors: sun, frost, wind, shock loads. Under their influence, the thermal insulator loses its properties and is destroyed. The win-win option for protection is the plaster of the facade of polyplex or other insulation:

1. Mineral plaster which consists of cement and polymers. It is endowed with a low coefficient of water absorption, resistant to fungi and mold, it is easily applied, effective when the facades are insulated.
2. Acrylic compositionwhich is elastic, has good water repellent characteristics, is not afraid of the effects of UV radiation. If you live in place with increased level Humidity and do not know than plastering the penplex outside, boldly use this composition.
3. Silicate mix It is quite effective, elastic, anti-static, vapor permeable, resistant to the effects of climatic precipitation.
4. Silicate plaster, which has high rates vapor permeability, elasticity, resistant to aggressive chemical compounds, microorganisms, ultraviolet. But the value of it is much the above described, it is harder and in color palette Pastel tones prevail.

A plastered surface can be made smooth and embossed. Choosing a plaster mix, be sure to see which texture it is intended.

In resistance to mechanical loads, experts consider effective acrylic plaster, then the silicate, mineral is followed. For service life affects surface texture: smooth is more sensitive to external influence.

It is also worth noting that mineral wool is used for the facade insulation. This material has such qualities as:

• good resistance to fire;
• high vapor permeability, water-repellent parameters;
• environmental well-being;
• long service life.

Such thermal insulation will last long and securely protect the walls of your home. Modern products are processed in the process of manufacturing with water-repellent compositions. Previously, the disadvantage of mineral wool was considered the release of formaldegd resins from it during its production, but modern technologies helped get rid of this shortage.
In 2009, the International Cancer Study Agency (Mair) on the basis of the confirmations of the NTP organization (National Toxicology Program) in the United States assigned the 3rd group on the Mair classification (IARC / CIRC). This includes materials that do not belong to the category of carcinogens for a person, like tea, coffee. And in 2010, the World Health Organization Mineral Wat is recognized completely harmless.

The heat insulator is attached to the wall with a glue composition and then, for reliability, a dowel with wide hats are clogged. Next, the reinforcement process takes place, the plaster on the Minvat - as well as by polystyrene foam, and the painting of the facade.

Facade shocking technology

The choice of the desired composition is an important point When insulating outdoor walls at home. But the quality of the coating depends not only on the material, but also from the plastering of the insulation. Make it need correctly, observing a certain sequence.

Performing plastering, remember that one wall should be worked out at once, otherwise traces of the connection will remain on the surface.

The stucco on the insulation is applied to the surface not earlier than 3-7 days after the construction of the lining plaster. Requires requirements Snip 3.04.01-87 "Insulating and finishing coatings": The temperature is not lower than + 5 ° C, not higher than + 25 ° C. Not allowed strong wind, precipitation.

To apply plaster layer, you will need:

• mixer for construction work or a perforator with a nozzle for mixing the solution;
• capacity;
• large and small spatulas;
• halfury or grater.

If you know how to plaster mineral wool, but you do not know how to plaster the penplex, then understand that the difference in processing insulation at this stage does not exist. First of all, using a mixer mix the solution in the container, on the package is written detailed instructions. The plaster solution is applied to a small spatula on a large and distribute the composition evenly vertically along the wall, pulling it out.

Surplus collect the grater, which is kept under a slight tilt and easily pressed against the wall. Excess plaster mix with the bulk of the tank.

Grouting the next section of plaster starting the connection site with the previous one. The solution should not be dried at the scene.

When the layer of plaster slits slightly, a smooth grater moistened in water, we drag the surface to level defects, and then we give the wall to the desired texture using a grater from an artificial material.

Painting facade

When the walls are dried, they can be painted. About how paint choose to work and how to calculate required amountYou can learn from the article "Paint for Facudes". To work, you will need a cuvette, spray gun or roller on a telescopic handle, brushes, a round brush from natural bristles, greasy tape, polyethylene film.

Any paint will make the color of the facade homogeneous, it will protect it from the effects of moisture and pollution. All plaster mixes except acrylic, we recommend painting.

Be sure to protect the base and its upper edge. If you paint with a roller or brush, then quite enough painting tape, and if you use the paintopult to work, it is better to close it with tight paper. Close the windows, fits, metal parts of the building with polyethylene film.

Lime paint is considered extremely beneficial for plastered surfaces, as it is diluted with water, but it is not durable.

Using it for work, follow the requirements GOST 12.3.035-84 SSBT "Construction. Work painting. Safety requirements", Do not forget about your safety - take advantage of rubberized gloves and protective glasses. Spray paint on the skin is easily flushed with water, only need to be done in a timely manner.

The final layer of paint is applied to a separate wall in one pass without interruptions so that the connection locations are not visible on the surface.

It is much faster and more convenient to operate with the paint sprayer. You need to start from any angle, move up-down movements. But be sure to use personal protective equipment: glasses, gloves and clothing.
Paint brushes are needed for surface procession in hard-to-reach places.
Working with roller will not cause special difficulties. The area of \u200b\u200bthe plot to be processed at a time should not exceed 1 m 2. In the cuvette we roll the roller, it is soaked in paint, and we will drive 3-4 bands on the walls. After that, they roll the roller until the paint is uniformly distributed over the surface.

Among the most common errors can be called the following:

• Performance of work with adverse climatic conditions, in this case the wet facade forms cracks or surface swelling.
• Poor-quality surface preparation.
• Poor-quality and loose docking of the heat-insulating material.
• Incorrect position of the reinforcing grid, a small backstage.
• Laying the grid directly on the thermal insulation layer.
• Error selection of material and its inconsistency.
• Failure to comply with the rules for fastening the insulation in a checker order.

Warming even cottageAll the same will have to use forests or subordinates. If you work one, so as not to drag them from place to place, better work Conduct on areas: height on the growth of the stacker, and in width - to focus on the dimensions of the lobes.

Deciding to insulate your home various materials, you can combine them.

The protruding part is lined with a "wet facade" shot. In this case, you should not use mineral wool, since when installing it will be saved.

Difficulties in the paper will deliver a polystyrene drop, but the result with this material will be great.

The installation of "wet facade" should be carried out in the spring-summer period, then it will not be necessary to build a heat outline, which will not entail additional cash investments. In case of violation of the installation technology, the greenhouse effect is likely, and this destructively affects the plaster layer.

Classic material used for the construction of private houses is a brick. He has many advantages, but there are bricks and disadvantages. Among them are high thermal conductivity and the tendency to accumulate moisture. To preserve integrity brick walls And ensuring comfort inside the structure, the wet facade finish is performed, and how to implement this technology with your own hands will be described below.

Features of the wet facade system

The facade of the cottage can be decorated in different ways. Against the background of a wide variety of technologies, a wet facade system is highlighted. What is the method of insulation and protect the external walls of residential buildings and industrial buildings from the impact of negative factors?

The insulation of houses of various purposes on this technology implies the coating of the outer walls of moisture and frost-resistant material, and then plastering and painting the facade. Also, instead of applying plaster and paint, special decorative panels can be used or executed finish finish clinker tiles. We describe the layer-by-layer structure of such a cladding in the table.

Layer	Comprises	Purpose
Heat insulating	Insulating material, adhesive mixture and dowels	Provides a facade of residential buildings High heat and sound insulation qualities
Keeparming	Adhesive mixture reinforcing grid, soil	Provides lining of a residential house Strength, wear resistance, durability, high external aesthetics
Decorative and finishing	Decorative plaster, panels, other finishing materials	Such a design gives the structure of attractive external species, Additional protection for its walls from external influence

In other words, such a system is a complex layered structure, so that the external walls of the residential building are provided with reliable protection.

Device of wet facade

Advantages and disadvantages

The decoration of the external walls of residential cottages was a wet method in recent years, as it has a number of advantages:

• provides the facade of the house high resistance to wear, durability, practicality. Serves such a system without losing its properties for more than 25 years;
• essential advantage of a similar facade system is its affordable cost. In the case of the use of polystyrene foam of sch, the facing will cost 1500-2000 rubles, and when using Minvata, the price will double. However, other ways of facing the external walls of residential buildings, which would have similar operational parameters and practically did not have the shortcomings, it will be more expensive to you;
• warming at home this way makes it warmer, comfortable for living. Thanks to such a decoration inside the housing, a healthy microclimate is formed, which positively affects the well-being of each family member. In addition, the positive quality of the wet facade of the house is the possibility of saving at the cost of electric or gas transmission. And if you still conduct insulation of windows, then no frosts will be terrible;
• the fact that the insulation is mounted on the walls on the outside, saves the precious square meters of living space inside the structure and even in those places where there is a window;
• thanks lightweight Such cladding can be applied without additional strengthening of the foundation and walls of the house;
• relatively easy implementation in practice without the help of professional builders;
• according to this technology, the departed house looks incredibly attractive, and his design successfully fits into the surrounding landscapes. We also note that after some time, if desired, the finishing layer of cladding can be replaced or updated.

Wet insulation options

Note that for the wet facade, some drawbacks are also characteristic. For example, it is not recommended to separate the facade and implement it. insulation workIf the air temperature dropped below 5 ° Celsius. In addition, it is not necessary to equip the facade in this way if the level of humidity is increased or there are precipitation. Such weather phenomena prevent uniform grazing of layers of facing.

Types of wet facades

Finishing private houses using a wet facade technology can be implemented with their own hands. But before starting work, it is necessary to decide on what kind of it is relevant for the walls of your home:

• heavy - The name displays the main difference between the facade of this plan: a significant weight, which limits the possibilities of applying this technology;
• lightweight technology can be applied to private houses raised from any building material.

Easy
Heavy

Heavy

In view of the rather high weight of such a finish, it is relevant to apply for walls from those building materials that can cope with such high weight load: brick, cellular concrete or ceramzit concrete blocks.

Fastening insulation dowels

The distinctive characteristics of the heavy type wet facade system is the fixation of thermal insulation without the use of adhesive composition. The insulation is fixed on the base through special hooks dowels. They are installed on the wall, only then they mount the insulating plate of the slave character. Heat insulating layer Additionally, fixed by means of reinforcing metal, and after the plastering solution is used and the finish finish is carried out.

Due to the fact that the metal grid must be masked, the plaster layer is obtained thick, heavy. Hence the name of the cladding method.

Easy

This method is quite common, as it is available for the price and is easily implemented in practice. The weight of the design is minimal, so it is applicable to walls built from almost all standard materials: brick, concrete, foam concrete, stone, wood, and so on.

The wet lighting facade system implies the use of finishing materials in several layers:

• the first layer of plaster will be basic and allows you to apply the reinforcing grid to make additional strength cladding;
• the second layer of plaster will be aligning and will allow the foundation of perfect evenness;
• the third layer (finishing) can be made by different finishing materials: paint, decorative plaster core, siding, decorative panels, the like. The main thing is that the selected option has as low weight as possible.

It should be noted that the facade finishing of a light type should be carried out by means of a fine and air-permeable plastering mixture. And the total thickness of the layers of all cladding, and including on the slopes of windows, should not exceed 10 mm.

Main nodes

To date, the wet facade finish is used most actively, which is due to a large amount of the advantage inherent in this type of finishing. By itself, this technology is a multi-layered design, each of the layers of which is aimed at performing its function:

• the first is a wall of the building, which before the start of work, begins a certain preparation, which consists in alignment and purification;
• the second is thermal insulation material, which can be used foam or mineral wool. The first option is cheaper, but the second is distinguished by the best characteristics;
• the third is a reinforcing lining designed to protect the plates with the further finishing process;
• the fourth is a decorative layer for which decorative plaster or other finishing materials can be used.

Types of insulation

An important step in the implementation of the technology of the wet facade is the choice of insulating material. What material is optimally applying for this purpose? In most cases, the masters use mineral wool in the form of plates. This is a rather rigid material, the density of which exceeds the indicator 150 kg / m³. Also, a foam is used to finish facades in such a way. The main thing is to choose the brand correctly (at least 35).

When comparing these two insulation, experts note that the best option is the minvat, because it is resistant to fire and is distinguished by high air permeability, which is extremely important in the case of the walls of the stone house. When insulation of the minor moisture from the masonry freely comes out through the pores of the material, which allows you to recreate the optimal microclimate inside the home and significantly improve the thermal insulation parameters of the facade. If the budget for repair work is extremely limited, then it is necessary to prefer the cheaper in the cost of the foam.

Remember, choose only products from proven manufacturers with a known name, the quality of the products of which is confirmed documented. Then the facade will definitely be durable and resistant to wear.

Mineral wool
Styrofoam

When arranging a wet facade, attention should be paid to the selection of finishing material. To facilitate the task, we propose to carefully familiarize yourself with possible facade systems that are ideal for such a finish:

• organic - with this method of finishing, you will need polystyrene plates, organic reinforcing mass, organic or silicone plaster;
• mineral - In this case, for insulation will fit mineral plates, and for reinforcement - mineral mixes. As for the decorative layer, it is worth choosing silicate or mineral plaster;
• combined - in such facade system used both polystyrene and mineral materials. The first will suit as a heater, and other materials can be used for reinforcement and subsequent shockting.

Separately, it is worth staying on the selection of suitable adhesive compositions. The best option For a wet facade, Crescent Crescents will be glue. As for plaster, the most suitable will be such species like a fur coat or a coroede.

Combined

Organic

Possible errors during work

When a wet facade device, a number of errors are often performed negatively affecting the quality of the coating:

• ignoring temperature modes work - this may cause destruction, detachment and even rotting the layers of the system;
• incorrect preparation of the main layer - the duration of the service will significantly decrease due to the destruction inside;
• the appearance of air sucks between the seams and layers, which can occur in the area of \u200b\u200bthe windows, will lead to the appearance of cracks on the surface of the facade and the building design will be spoiled;
• the wrong installation of the reinforcing grid is the cause of chips and cracks on the outer layer.

Service life and repair

The facade, decorated with a wet way, can serve up to 30 years. But this period may well vary in a large or smaller side, which depends on humidity, climatic conditions and possible temperature differences.

During operation, the wet facade may be subject to repair work If necessary. But for this you need to save documents for all construction MaterialsSo that if it is necessary to dye a certain area to purchase a paint used earlier. In the opposite case, you can not guess with a tint and then the stain release will appear on your facade.

If after time you will notice that a piece of plaster began to be tracked on a certain area, which is especially often occurring near the windows, then in this case it is necessary to carry out the following works: Clean this place to a strong layer, load and impose a new layer of plaster.

Video

To better understand the principle of the device of the wet facade, we advise you to watch the video.

- This is the generalized name of all finishing workwhich use liquid or viscous adhesive mixtures for fastening the facing material.

It does not matter how the glue was carried out - ready-made or mixed immediately before use. The most common type of technique was wet facade - decorative plaster, which has recently been often done simultaneously with insulation. In this technology, insulation material is also attached due to adhesive solutions.

The main advantage of the wet facade is a reduced to a minimum number of cold bridges and the removal of the dew point to the outside of the premises, so that there is no condensation inside the building.

This is not the only advantage of the selection of the wet facade. What can this technology be suggested? Let's consider:

1. Installation of the wet facade does not apply to complex work. He can do any craftsman, even though working with plaster.
2. The cost of materials for this technology is low. If you choose a foam and miserable to choke the insulation over the plaster, then you can invest in 300-600 rubles per square meter of finishes.
3. The wet facade of the insulation allows you to reduce the thickness of the outer walls and save on construction.
4. Such decoration does not aggravate the facade walls, therefore it can be used in any type of foundation and wall material.
5. Since insulation is mounted outside the building, it does not take valuable centimeters at the living area.
6. This method is not limited to the decorative solution of the facade: thanks to the facade plaster you can make the most different texture and the color of the walls, and if the plaster mixture is white, then you can additionally paint, using the most diverse palette facade colors. The "Wet" method also provides for use ceramic tile And artificial stone, whose variations are difficult to count.

FEATURES OF MONTAGE

Installation of the insulation system wet facade should pass under certain climatic conditions and with a thorough selection of materials, otherwise neither finishing, no heat insulation will be able to last long.

Be sure to consider that:

1. The finish "Wet" can be done only in the warm season. This is due to the fact that with cement solutions It is impossible to work as low temperatures. According to the standards, if the temperature is reduced to +5 and below, then work is transferred to "up to better times" or create an insulating canopy, which is capable of maintaining the optimum temperature.
2. Rainy weather is also not suitable for mounting the system. If you do not want to get a decoration with stains and divorces, then it is better to transfer insulation and facing until clear sunny days appear.
3. Decorative plaster can serve about 30 years, if the climate in your region does not have sharp drops of seasonal and daytime temperatures. Than crash dropsThe faster the decorative layer is destroyed.

This technology is so simple that it is almost impossible to allow errors during installation. But the quality of the finish can severely suffer from incorrect selection of materials.

Choosing plaster

Wet facade of the installation technology of which allow applications different species Decorative plaster, which in one way or another correspond to the technological process:

• Mineral - budget plaster, which has good vapor permeability and low moisture absorption. The price fluctuates due to the presence of additives as part of a different value, but still be at the level of available.
• Silicate - possessing good vapor permeability. Due to bad adhesion, it is not used without special primer.
• Silicone: elasticity, vapor permeability, good adhesive makes this plaster almost perfect if low cost.
• Acrylic: Despite the excellent moisture resistance, this plaster has a significant minus - low vapor permeability, which makes it unsuitable for some species of the wet facade.

One of the most economical options The effects of decorative plaster - a croroede, but it is not so easy to apply, as it seems at first glance.

What insulation is better for technology

For the wet facade system, only tiled insulation can be used to obtain a reliable, uniform heat-insulating and decorative layer.

That is, chooses among mineral wool and expanded thermal insulators. During the selection, we draw attention to such qualities of the insulation for the wet facade:

• Vapor permeability;
• Moisture absorption;
• Density.

Parry permeability should not be low. It is desirable that it gradually increases from the inside to the outer. Then you can avoid condensate falling right in the middle of the insulation system wet facade. Extra moisture It acts destructively on thermal insulation and finishing. For the same reason, insulation with high moisture absorption cannot be taken for work.

Therefore, among mineral wool slabs stop in basalt or diabaz. Stone wool is quite moisture-resistant and has excellent vapor permeability, but its density should not be below 90 kg / m2, otherwise with difficulties and insulation can stratify after a few years. The permissible density of the plates of Minvati under the plaster - 180 kg / m2.

Attention! The insulation of facades of mineral wool slabs "on wet" categorically prohibits the use of acrylic plasters.

Polyfoam and extruded polystyrene foams practically do not absorb moisture, as well as at low density are convenient for applying plasters. But it is preferable to work, since it has at least some vapor permeability, and its extruded polystyrene foam is simply not.

The stone wool foams won not only in density, but also by thermal conductivity: a polystyrene foam plate with a thickness of 50 mm has the same thermal insulation qualities with a cotton plate of 110 mm thickness.

There is a slight advantage of basalt fiber in vapor permeability, it is eclipsed at the sight of the price difference between the first and second option. It is because of the availability and not bad correspondence of the technology of a wet facade for work, foam is often chosen.

Attention! Adhesive mixtures for mounting mineral wool slabs and foam flames are different. Therefore, for each insulation, glue is taking suitable under its characteristics.

We make the "wet" facade of stages

1. The device of the wet facade begins with the preparation of the facade surface: cleaning from pollution, alignment of the walls and sealing cracks of putty or adhesive mixture, primer.
2. Then the installation of the base profile by self-assembly at the top level of the base. The base itself is rarely insulated. To distinguish the base part of the building, make facing with artificial or natural stone.
3. Warming is reached upwards, starting from the level of the base profile. A glue solution is applied to the plates: along the edges - a solid layer, in the middle - point method. Additional fastening is carried out by plate dowels after 3 days, data to set glue.
4. Then the reinforcing layer follows: a glue solution is applied, in which durable is pressed. Special reinforcing corners are fixed in the corners. This is the penultimate stage of the wet facade finish. The technology requires to take a break of about 3-7 days to set the reinforcing layer, after which it is possible to start applying the decor.
5. Decorative stucco is applied strictly according to the manufacturer's instructions. If painting is required, then it is made of two-layer, alternating vertical and horizontal application. In this case, the colorful layer will be uniform, without any transitions in the tone.

On the video below, the insulation technology "Wet facade".

If under tile or artificial stone It is planned to be mounted insulation, then the waterproofing of this site is additionally carried out.
