The presentation of the article is intended for those who have not been holding a spatula in their hands for the first time. Therefore, the technique of applying facade plaster or glue for expanded polystyrene insulation is not explained in detail.

But the photos of wet facades will perfectly demonstrate the difference in the technology of installing the plaster mesh in two ways, popular with folk craftsmen. This will allow you to calculate the feasibility of applying one method or another on various parts of the facade.

Wet facade - fiberglass mesh plastering technology

This is a lightweight, thin fiberglass mesh that is sold in rolls. It comes in a variety of colors (usually blue, white or green). Its main property is resistance to solutions with an alkaline reaction. Unlike heavy welded metal meshes, which are used when plastering brick walls, fiberglass plastering mesh is successfully used in the wet finishing of facades insulated with expanded polystyrene.

By purchasing such a mesh in the construction market, you can get a lot of useful tips and tricks from the "experienced" on how to use it better.

We demonstrate two ways of attaching the plaster mesh when reinforcing a wet facade.

Technological method of fastening plaster mesh glass (for the pros)

The main steps for installing wet facades in this way.

We measure the length of the mesh from the roll, equal to the height of the wall section, which is being prepared for plastering.

We mix the plaster mixture according to the instructions on the bag. Instead, glue is often used for expanded polystyrene insulation boards, which makes sense, since the adhesive mixture has the highest waterproofing and hydrophobic properties.

In the photo - just such a mixture.

Apply a layer of mortar, 2 to 5 mm thick. This must be done as quickly as possible, along the entire height of the wall segment. We even out small (up to 5 mm) differences in the level of the wall, but we do not try to "remove" the influxes - it is too early.

Immediately apply the plaster mesh to the top of the wall, placing it strictly vertically.

Press the fiberglass into the plaster layer using the widest spatula available on the farm.

In one place, you need to make no more than 2-3 sweeping movements:

• press in the mesh;
• cover the mesh in the "bald spots" with a thin layer of mortar;
• bring the site under the general level of the wall - align.

Pros and cons of the method

Disadvantages of the method:

• the cut mesh “gets tangled underfoot” and is easy to get dirty;
• foam balls, escaping from the insulation layer, stick to the spatula and interfere with the application of the solution;
• It is difficult for a beginner to single-handedly apply a plaster layer to the entire height of the wall and apply the mesh strictly vertically to the wet layer.

Advantages:

• dry mesh is laid without folds;
• easily pressed in evenly;
• many find it easier to bring the wall out perfectly straight using this method.

An alternative way of attaching the plaster mesh (for beginners)

We cut off a segment from the mesh roll, the length of which will be equal to the height of the wall section plus 5-7 cm.
Using an assembly stapler, we nail the mesh to the upper part of the wall or to the wooden part of the roof using an allowance. The net should be fixed in a strictly vertical position.

We mix the plaster solution. Apply a layer of plaster mixture 2-5 mm thick directly along the mesh, trying not to leave empty spaces between the mesh and the insulation. You need to start doing this from the highest point of the wall, moving down. Slightly level the differences in the walls, but don't worry about perfect smoothness yet.

It is not necessary to apply the solution to the entire height of the wall - you can repeat the following steps in 2-3 steps, moving from top to bottom along the wall.

Grasping the bottom dry edge of the mesh, pull it towards you, completely separating it from the wall and the wet layer of mortar. Then release, without pressing, lay on top of the plaster.

Apply a small amount of the solution to a wide spatula and cover the mesh with it, moving your hand from top to bottom.

Smooth the wall with wide arcuate movements to make it as smooth as possible for painting.

Advantages and disadvantages of the method

• during operation, the mesh gets a little wet and becomes heavy, which makes it difficult to remove it from the wall surface (stretches, forms waves, wrinkles);
• the result at the exit may not be pleasing: it is difficult to achieve a mirror-like flatness of the surface, like that of the pros.

• pre-fastening the mesh allows you to break down the work into stages that are available for a beginner to perform, even alone.

On the feasibility of two technologies for mounting a wet facade

To master the technological method, first try sections of walls with a small height (under the windows, above the doorway). This will allow you to evaluate your strengths for applying the correct do-it-yourself wet plaster technology.

Carrying out work on plastering surfaces is an important and responsible task. It is imperative to observe the correct technologies that will allow you to securely fix the material on the wall without unnecessary difficulties so that it does not peel off under any circumstances.

The mesh reinforced for plaster is best suited to address this issue, since it can be used to create a special layer that, on the one hand, will improve adhesion to the wall, and on the other hand, it will allow the material to be securely fastened together. This approach is used when performing a large number of construction work, and it has proven itself only from the best side. So it is used everywhere and is always satisfied with the result.

What is a plastering grid?

Reinforcing mesh for wall plastering fully corresponds to its name and is a special product that has small cells that effectively contain the solution so that it does not fly in different directions and sticks to the wall as tightly as possible.

There are the following types:

• ... masonry mesh, which has cells of 5x5 millimeters and is used with brick walls. Manufactured mainly from polymers;
• ... station wagon mesh, which can have different mesh sizes and is used in all types of work where it is necessary to cover a large area at a time;
• ... fiberglass mesh, which has a cell size of 5x5 millimeters and is highly resistant to any kind of chemical attack, and also easily tolerates high loads that can be detrimental to other materials;
• ... plurim mesh, made of polypropylene and having a lightweight mass, which makes it easy to use without a strong increase in the load on the walls;
• ... armaflex is a polypropylene material with reinforced knots. It is used for those types of work where an increased level of load is expected;
• ... syntoflex - has "immunity" to chemical and mechanical stress;
• ... steel mesh - is one of the most durable models, but not suitable for outdoor use due to its low resistance to atmospheric precipitation;
• ... galvanized mesh - is a modification of the previous model. With the help of special processing, it received protection against corrosion, so it is applicable for any purpose, including operation in high humidity conditions.

The range of products is quite large, so you need to know how to choose the right material when buying. The sales assistant will try to sell the product that is beneficial to him, so it is better if the client himself understands the varieties.

How to choose a mesh for plastering work?

Inexperienced users often have the question of what mesh to reinforce the plaster with? Here everything will depend on the current working conditions, since there are not only universal models, but also narrow-profile products suitable for only one purpose. Therefore, you need to first consult with the masters or search for the necessary information yourself. The correct choice is very important for further operation, so you need to take it seriously.

Reinforcing fiberglass mesh for plaster is one of the best universal models, since it combines almost all the positive qualities that such a material should have. It is not afraid of corrosion, since it does not contain metal elements, is not sensitive to moisture and temperature extremes, and withstands mechanical stress well. Therefore, many professionals advise purchasing this particular model.

In any case, the reinforcing mesh for wall plastering in its performance should not be inferior to the main material. This is especially true for strength, reliability and durability. The base simply must stand no less period than the finishing material, otherwise all sense in its use is lost.

How to work with mesh reinforcement?

Reinforced plaster mesh must be securely and tightly attached to the wall so that it does not upset the correct balance that will be established upon completion of the finish. Its installation is carried out in a phased mode according to the following scheme:

• ... First, the working surface is divided into separate zones, in each of which a certain number of beacons are marked. They can be calculated using a standard formula, the main indicator of which is the squaring of the wall to be treated.
• ... Next, using a drill, holes are drilled and fasteners of the reinforcing mesh for plaster are inserted. They are quite standard screws, but with large diameter heads, which will securely hold the mesh and press it against the wall.
• ... Next, a base layer of plaster is put on, without using a mesh.
• ... After that, the mesh is put on the fasteners and tightened as much as possible. But do not overdo it so that the material does not burst from excessive stress.
• ... On top of the installed mesh, finishing work of the final level can be carried out. At the same time, the plaster will lie flat and adhere without any problems. The main thing is to smooth out the top layer well so that it looks beautiful.

The price of a reinforcing mesh for plaster will depend on the type chosen. The larger the size of the cells, the correspondingly and more expensive the cost of the material.

During construction, reinforcement is an irreplaceable material. Reinforcement allows you to strengthen the structure and extend its service life. But why do you need to reinforce the walls, and what materials are needed for the work? We'll figure out.

Very often, in the process of construction or repair, you can encounter many wall defects, which are quite difficult to mask or remove completely. You can level the wall with a ball of plaster. But if there are many rough irregularities or cracks on the wall, then the plaster itself will not be able to hide them. In such cases, mesh wall reinforcement can be applied.

The reinforced surface is more elastic and withstands mechanical stress better. Reinforcement of walls with mesh is recommended if the thickness of the plaster is 2 centimeters or more.

What is reinforcement used for?

Reinforcement is used in such cases:

1. Irregularities in the walls. In the process of leveling the walls, you may encounter very large irregularities, for which you will have to make a large layer of plaster to hide. But the plaster itself is very heavy and if the layer is rather thick, then it can swell and flake off.
2. The wall is too flat. In such cases, the mesh helps the mortar adhere more tightly to the wall.
3. Cracks. With the help of mesh reinforcement, the size of large cracks can be significantly reduced, and if the cracks are smaller, then they can be completely hidden. Also, the mesh prevents the appearance of cracks and microcracks if used in the construction process.

How to choose the right mesh for wall reinforcement?

There are many nuances to be aware of when choosing a mesh. Reinforcement mesh can be metal, plastic or fiberglass.

The metal mesh is suitable for reinforcing walls with large irregularities (more than 4 centimeters). Metal works well in an alkaline environment and such meshes can be used for plastering with a solution that contains cement. The use of metal meshes is also recommended if the plaster is to be carried out with clay. Only in this case it is better to take a grid with a cell size of 50 × 50 millimeters. It is also good to reinforce walls with metal mesh, which often give in to mechanical stress (walls of a garage, the first floor of a building).

The use of plastic mesh is only possible if the plaster does not contain cement. Often used with gypsum mortar for finishing wall plaster. Such mesh is cheaper than metal or fiberglass, but also not durable. Working with such a mesh requires experience, as it quickly sags and deforms.

If the plaster layer is thinner then fiberglass mesh is possible. Such a mesh retains crack opening relatively well, but of small dimensions.

Installation of the mesh

In order to attach the mesh to the wall you will need:

• dowel-nails d = 6mm and self-tapping screws 4.5mm;
• puncher;
• wire for knitting mesh;
• scissors for cutting metal:
• lighthouses.

The surface of the wall must be cleaned and primed. Cut the mesh into pieces so that the piece is the entire height of the wall. We start fastening from the bottom with the help of dowel-nails and go to the top.

To fix the mesh, you can bend the edge of the nail or use galvanized mounting tape. The mesh is also often fixed with a knitting wire. For this, the dowels must be hammered in not completely and a wire must be attached to the hats with the letter Z. After fastening the wire, the dowels are finished.

When calculating the required number of dowels, you need to know that about 16-20 pieces will be spent on 1m².

In order for the mesh not to sag or deform, it is necessary to stretch it well and press it tightly against the wall surface. If there are places where the mesh lags behind the wall by 1 centimeter or more, then the plaster can peel off the surface there. The joints must be overlaid. After fixing the grid, beacons are set up.

Then you can proceed to the first layer of plaster. It must be made with a liquid solution. It is necessary to apply the plaster solution with sharp movements so that it adheres well to the wall between the cells of the reinforcing mesh.

If the first layer is well dried, then the second can be applied. The finishing ball of plaster is made from a thicker mortar. Application should be done from the bottom up.

Facade finishing is one of the most important building operations. Exterior wall cladding is exposed to atmospheric precipitation, cyclical freezing / thawing and exposure to harsh ultraviolet rays. Such difficult operating conditions place high demands on the quality of the finish. It is very expensive and time-consuming to eliminate defects on the facade walls. We'll have to mount scaffolding, wait for good weather, and remove construction waste. To exclude the occurrence of unpleasant situations, you need to take all measures to prevent them.

Facade wall decoration is carried out with various materials and technologies. Reinforcing stack is used in two cases.

To improve the performance of the plaster layer. For such purposes, it is better to use a galvanized wire mesh.

Full metal mesh

The fact is that among the many advantages of foam blocks, one must definitely pay attention to one very significant drawback - low physical strength. Another problem is that concrete blocks begin to crumble during freezing / thawing in conditions of high specific humidity. As a result, cement plaster begins to flake off with all the negative consequences.

Reinforcing mesh allows the plaster to adhere to the wall surface. Conversations that such a mesh should be used with a large thickness of plaster, which due to this, does not appear on the plaster of cracks, have only partial confirmation. Firstly, there are simpler and cheaper methods of eliminating the appearance of cracks in thick plaster. The easiest way is to cover the solution in a thin layer in several steps. Secondly, it is possible to increase the adhesion of the mortar to the facade wall due to a slight increase in the amount of cement in the mortar. If this is not enough, then a spray of cement milk is done.

To protect the insulation of the facade walls from destruction. Reinforcing facade mesh is used during the finishing of foam insulation boards.

Not to improve the adhesion of glue to the surface of expanded polystyrene and to prevent cracks, as some "sofa" builders write, but specifically for mechanical protection.

Why do we say so? The surface of the expanded polystyrene is protected from the negative effects of ultraviolet rays and, oddly enough, damage from birds. For some unknown reason, birds are very fond of pecking on styrofoam, if you leave it unprotected, then soon many large and small depressions will appear on the surface. Conclusion - polystyrene foam needs to be closed. The cheapest and most reliable method is to use glue.

By the way, the advertising characteristics of manufacturers of plastic reinforcing nets “they are not afraid of UV” do not in any way affect their actual performance. The fact is that even the thinnest layer of glue or other cement-sand mixture completely does not transmit ultraviolet rays. Why should a consumer pay for properties that he doesn't need? And one more nuance. Most often, builders fix the reinforcing mesh on the entire wall. We think that this is done either out of ignorance of physical properties, or by a desire to earn more. We advise you to use a reinforcing mesh at a height of 1.5–2.0 meters, there is no need above. No one will damage the finishing screed so high on the Styrofoam. Mechanical damage occurs due to various shocks, careless chores near the front wall, etc.

Types of facade reinforcing meshes

Facade reinforcing nets are made of galvanized wire or polymers. The former are used for facade plastering, and the latter are for universal use.

Metal mesh fixation technology

Metal meshes are used only for cement-sand facade plasters, foam insulation is not finished with them. The reason is the small thickness of the screed on the foam plates. And the metal mesh cannot be aligned with such precision; it must be pressed with a thick layer of mortar. The metal facade reinforcing mesh is able to withstand great efforts, it is used if it is necessary to apply a thick layer of plaster on an uneven base.

The algorithm for fixing it has several features, the implementation of which guarantees the expected effect. The mesh can be laid in both vertical and horizontal stripes. For the strength of the plaster, this does not matter, decide for yourself how it is more convenient for you to work. How to properly fix the metal mesh to the facade wall?

Step 1... Take the dimensions of the wall, cut the metal mesh along them. Select the cutting tool according to the wire diameter. Universal tool - metal scissors.

If they are not there, then a thin mesh with a wire diameter of up to 0.8 mm can be cut with ordinary scissors. True, after that, these scissors will have to be sharpened, they will no longer cut the paper.

Prices for construction scissors for metal

Step 2. The metal mesh can be fixed with dowels, the length of the hardware must provide a strong fixation. For facade walls made of foam blocks, ordinary nails 80–90 mm long can be used. They are easily driven into blocks with an ordinary hammer, working with them is much faster and easier. Nails are much cheaper than dowels, and the quality of fixation is no different. Use dowels only on brick or concrete facade walls.

Step 3. Using an electric drill with a hammer drill, drill the first hole for the mesh. The depth of the holes should be several centimeters deeper than the length of the plastic part. Otherwise, it is impossible to insert the dowel to the required depth - the hole is slightly filled with brick chips during drilling and reduces its effective depth. It is difficult to remove it from there, it is better to drill out more.

Important. The height of the protruding part of the dowels should not exceed the thickness of the plaster mortar. Keep track of this parameter throughout the entire area of ​​the facade wall so that you do not have to adjust the dowels during plastering.

Step 4. Drill holes in one line at a distance of about fifty centimeters, hang a mesh on each dowel. Stretch it a little, do not allow large irregularities. The position of the line does not matter, it can be vertical or horizontal, depending on the method of fastening the reinforcing metal mesh.

Step 5. Check the position of the opposite edge of the grid, if it lies unevenly, then move the grid to adjacent cells.

Fastening the plaster mesh - diagram

Step 6. Everything is normal - continue to fix the mesh, install the dowels in a checkerboard pattern. Most metal meshes are one meter wide, so you need three rows of hardware to fix it.

Important. In places where two rolls overlap, install the dowels at a distance of approximately 10 cm from the edge. Two strips of reinforcing mesh will be hung on these dowels at the same time.

Step 7. In places of window and door openings, the mesh is cut to size. But it's okay if you don't cut it off, but just bend it. Just make sure that the edges of the folded sections do not protrude beyond the thickness of the plaster layer.

When plastering such a facade wall, the mortar must be thrown in several stages. For the first time, the mass should be slightly thicker than for the final leveling. Specific values ​​depend on several indicators and are determined individually, taking into account the practical experience of the master. The consistency of the mortar is influenced by the weather, the ability of the facade walls to absorb moisture, the linearity of the wall, the maximum parameters of irregularities, etc.

Step-by-step instructions for fixing plastic nets

The durability of its operation largely depends on the correct implementation of the recommendations for the installation of a plastic reinforcing mesh on a foam insulation. In all cases, do not rush, work carefully. We have already mentioned that there is no need to reinforce the entire wall in height, it is enough to protect only the lower vulnerable area. But these are our recommendations, if in doubt - protect the entire surface of the facade wall.

Any brand of glue is suitable for gluing the mesh. Read the instructions, it must have good adhesion to plastic materials. In most cases, a finishing layer of glue with a thickness of several millimeters is applied over the plastic reinforcing mesh. The topcoat is done with facade paints or a thin layer of decorative plaster.

Step 1. Examine the surface of the slabs. If they were fixed with dowels, then completely sink the caps and seal the indentations. You can close the slots at the same time, but this is not necessary. The fact is that the slots will automatically close during the application of the first layer.

Step 2. On the wall, draw a horizontal line along the height of the reinforcement layer. It will help you keep track of the height of the adhesive application. A thin layer of material dries quickly, and this not only causes an increase in material consumption, but also negatively affects the final leveling of the layer for painting.

Step 3. Prepare the adhesive according to the manufacturer's instructions. Always pour water into the container first, and then add the dry mixture. This technology will greatly simplify the mixing process. You can mix it manually with a trowel or using a mixer attachment to an electric drill.

The second method is not only easier, but also more effective. Stir for a few minutes, and then leave the mixture to stand for another 5-6 minutes. During this time, moisture will be evenly distributed throughout the entire volume, the smallest dry lumps of glue will completely disappear.

Step 4. The glue is applied to the wall with a spatula; the longer it is, the smoother the surface is. Professionals work with spatulas up to 70 cm in size, beginners can use shorter ones at first.

Practical advice. If you are just learning how to apply glue to the surface, then it is better to immediately get used to working with both hands. One gets tired - connect the other hand. Believe me, it's not that difficult, you just need to show a little endurance and patience.

Apply glue to the spatula with a trowel in the center of the tool. The number will be determined empirically. While applying the layer, hold the spatula at an angle to the foam boards, press down with medium pressure. Aim for a layer thickness of about 2–3 millimeters. Do not prepare a large amount of surface at once, for beginners, two meters in dyne is enough. If you do not have time to fix the mesh, the glue will harden, you will have to remove the old layer and make a new one.

Step 5. Try on the location of the plastic mesh reinforcement. If it doesn't fit into the window opening, trim the material.

Step 6. Glue one end of the mesh, align it horizontally to the length of the prepared wall section. Make sure that the mesh lies flat without distortions and bends, focus on the previously drawn line on the foam.

Practical advice. The mesh should overlap about ten centimeters. You can find recommendations to not smear the place of overlap of one line with glue, but to do it simultaneously for two rows. We do not recommend doing this, it only complicates the work. Glue the first row of mesh over the entire width at once, including the overlap. The second line will be glued on top of the freshly applied glue. This method simplifies mesh fixation and has a positive effect on quality.

Step 7. Use your hand to press the mesh against the fresh glue in several places, check its position again.

Step 8. With a spatula, begin to press the mesh to the surface of the insulation. Make sure that the glue of the first layer protrudes over the entire surface and evenly covers the mesh cells from the front side. If there is insufficient adhesive thickness, reapply it over the mesh reinforcement. Such passes may appear for inexperienced craftsmen. Over time, you will learn to determine the optimal thickness of the glue by eye and there will be no more gaps. Spread excess solution on free surfaces. You should not try to immediately make the surface perfectly flat, but you need to strive for such a result.

Step 9. Allow time for the glue to dry. It is better to leave it overnight, it is recommended to finish grouting the surfaces the next day.

That's the whole technology, the surface of the front wall is prepared for painting or finishing with other materials. We remind you once again that the plastic reinforcing mesh on insulated facades is used not to prevent cracks on the glue surface, but from mechanical damage to the foam. Keep this in mind when making your decision.

Facade mesh to protect the construction site

Compliance with safety measures during construction work on multi-storey buildings is one of the main requirements for all developers. This is especially true for objects being built within cities. The facade mesh is fixed on the scaffolding and prevents debris and tools from falling onto pedestrian walkways. For such purposes, the cheapest of the plastic reinforcing nets is used; after dismantling, it is suitable for direct use.

"Izumrud" - a new net for scaffolding

Question answer

Is it possible to repair exfoliated areas with a reinforcing facade mesh? It is possible, but it is better not to allow such situations. Unfortunately, in most cases, delamination appears a few months or years after the finishing of the insulated facade walls.

How is the repair done?

1. Revision the delaminated area. Use your hand to check that the mesh is firmly fixed next to the delaminated area. Prepare materials: glue and a piece of plastic reinforcing mesh. If the facade walls are painted, then you need to have the appropriate paint.
2. Pull the detached mesh towards you and use a sharp assembly knife to cut it around the perimeter. Work very carefully to avoid damaging the foam. If the sect continues to flake off during cutting, great. You remove the entire problem area in this way, it would peel off over time anyway.
3. Cut out a new mesh for the patch, the size should be slightly larger than the cleared area for overlap.
4. Remove the old adhesive from the foam surface.
5. With a spatula, carefully remove the top layer of glue from the surface of the remaining mesh to the width of the new overlap. Apply the first layer of glue, sink the mesh into it and apply the second layer of glue.
6. After it dries, flatten it. Pay particular attention to the docking location. It should be as flat as possible without sudden changes in height.

A wet facade is one of the most demanded types of exterior decoration of houses. It perfectly protects the building in the changeable Russian climate. The cladding is a multi-layer structure made of a primer, adhesives, insulation, decorative coating and other materials, in accordance with the selected manufacturing technology.

In a wet façade, the reinforcing mesh is an important component. It performs the function of adhesion and holding in a fixed position of all layers. At first glance, the procedure for applying it may seem quite simple, but it requires exact knowledge of the material and skills in working with it. Otherwise, your home will need recovery operations as early as next season.

Reinforcement layer functions

In the structure of a wet facade, reinforcement plays not only the role of a fixer for a multilayer cladding structure, it strengthens the entire structure, makes it more durable and resistant to mechanical stress, and also provides the following performance characteristics:

• The layer provides adhesion between the insulation material and the finishing layer of decorative plaster.
• The reinforcing layer relieves the risk of cracks when the multilayer structure dries, as well as during vibration or mechanical stress.
• Reinforcing coating prevents peeling of a wet facade and subsidence of the base.
• The layer increases the service life of the cladding.

Types of building materials for reinforcement

The choice of technology for making a wet facade determines what material will be used for reinforcement.

Previously, various methods were used, now they use fiberglass mesh with adhesives, as the most technologically advanced method for installation and operation. This material is plastic, easy to use and resistant to alkaline solutions.

Fiberglass reinforcing mesh is made as a cloth - by weaving the warp and weft.

At the final stage of production, the fibers are impregnated with polymers, thanks to which the material becomes resistant to alkali-containing substances. Also, the material is characterized by the following properties:

• incombustibility, that is, it does not increase the fire hazard of a building or structure;
• high strength, which provides excellent fixation of the multi-layer facade structure;
• a small mass does not weigh down a wet facade;
• strengthening the multi-layer facade structure reduces the number of cold bridges.

Technical characteristics of reinforcing mesh for facades

Specialists for the reinforcement of wet facades use a standard mesh with a density of 145 to 180 g / m2.

In addition to the reinforcing mesh, it is necessary to pay close attention to the physicochemical properties of the adhesives. They must be frost-resistant, durable and have good vapor permeability. Most often, these adhesives have a mineral base to which polymer additives are added. With their help, not only the connection of the layers is ensured, but also the partial alignment of the walls.

Wet facade reinforcement technology. Sequence of work

If you wondered how to perform reinforcement in a wet facade, then you understand how important this stage is. This procedure is carried out after the installation of the insulation boards with dowels and glue. The compositions must dry completely, therefore, you need to start working in 1-3 days, according to the drying time specified in the instructions. Reinforcement can be started after the adhesives have set in the areas to be reinforced (slopes, corners, etc.). The sequence of work must be strictly observed.

1. Preparation of materials. Adhesives are mixed according to the instructions. The mesh is cut to the size of the area to be reinforced, with a "margin" of 5-6 cm.

2. Application of glue. The composition is applied evenly over the entire area, directly on the insulation material. It is better to do this, starting from the corners and from the top point and moving downward.

3. Installation of reinforcing mesh. The material is evenly distributed over the wall and is "embedded" into the adhesive composition. Mesh fabrics are laid with an overlap of at least 10 cm.

The canvas is stretched and attached immediately over the entire area. Smooth the surface with the widest trowel available in the arsenal.

For your information

Make sure that the total thickness of the reinforcing layer is at least 4 mm and not more than 6 mm. The adhesive coating should be 2 times thinner than the mesh. And the reinforcing mesh should be 1-2 mm from the surface.

4. Chamfer on window and door openings. Where the mesh adjoins the openings, you need to chamfer at 45 degrees using a trowel.

5. Drying. The surfaces must be standing still and dry completely. Only then can you proceed to reinforcing the next section of the facade.

6. Preparation for finishing. After the reinforcing layer is formed along the entire facade, it needs to dry out for three days. Only then can a finishing plaster layer be applied to it.

When performing the procedure, you must remember two important conditions:

• work with adhesives should take place either in dry cloudy weather or in the shade.
• there must be a distance of at least 2 mm between the thermal insulation material and the reinforcing mesh.
• Experts recommend forming a wet facade on the ground floor with two reinforcing nets. Above, you can get by with one layer.
• In order to avoid sagging of the mesh and its uneven installation on the wall, work should be carried out by a sufficient number of workers.

By carefully following the above recommendations, you can reinforce the wet facade of your home yourself. It is best to start with small areas, such as under window openings. But if you are not attracted to experiments, and you want to carry out the work once and for many years, it is better to entrust the reinforcement of the wet facade of your house to specialists.
