And about how to set the grid for plaster do it yourself, we will talk further.

Actual tools and materials

Many people are interested in the question of how to fix the grid for plaster. The following tools and materials are needed for this:

• dowel nails for fixing the material on the base;
• drill for making holes in the wall under the dowel nails;
• beacons to create the most even surface;
• metal shears for cutting metal mesh;
• the rule for leveling plaster on the base;
• spatula for applying plaster on the wall surface;
• capacity for cultivation of plaster, you will prepare it independently, but will not get ready structure;
• level to analyze the surface for curvature.

We perform reinforcement

Is it worth it to reinforce the surface of the walls and ceiling, it's up to you. However, it is important to understand that in the case of strict adherence to technology and recommendations of experienced specialists, the reinforced and coated with plaster surface acquires a fairly high strength to the effects of negative factors in the environment.

Reinforcement can be done with your own hands and without the help of a professional team of builders, whose services can be quite expensive.

All the work can be done with your own hands in the following sequence of operations.

Surface preparation for finishing

Before fixing the mesh for plaster, it is necessary to prepare the surface for subsequent leveling and finishing. Only then will the results of your labors be of high quality and durable.

Clean the surface of the base from dust, dirt and grease stains. Next you need to study the wall for the presence of bumps and protrusions on it. They will need to be carefully cut or cut down with a sharp hatchet so that the base will acquire a more or less flat surface.

If the wall has cavities, then they will need to cover up with putty. This will reduce the differences on the basis of the optimal state.

Then coat the substrate with a special adhesion promoter. Only in this case, the plaster mortar will adhere well to the base, will not swell and will not crack with time.

Fastening the reinforcing mesh to the wall

First, take a drill and arrange in the wall the holes for the dowel nails so that on 1 square. m accounted for 15-20 holes. Next, you need to cut a piece of the grid along the height of the wall surface and attach it to the base with the help of a dowel of nails, moving from the bottom up. Stretch the mesh well and press it as tightly as possible to the wall surface to prevent bulges larger than 1 cm. Sheets of material must be overlapped so that the joints do not disperse.

And in the corners of the door and window openings it is worth performing an additional reinforcement with mesh pieces of 30x50 cm.

Only then proceed to exhibiting beacons and plastering the wall.

Base plastering

The initial layer of plaster should be applied with a thinner solution, making sharp movements. Then the material will leak through the small cells of the grid and adhere well to the surface of the wall. Next, the base should be a little dry. Be sure to check the wall for deviations from the horizontal with the help of a building level.

The second layer is attacked by a thicker solution and is evenly stretched by trowel movements from bottom to top. After drying the second plaster layer, it is worth performing the subsequent finishing of the wall or ceiling surface in the house.

Reinforcement leveling coating on vertical building structures significantly increases its strength.

Proper fastening of the mesh under the plaster will allow to achieve a high quality surface.

Steel wire, composite or polymer fibers that are in the thickness of the coating, takes on the main load.
  The reinforcing mesh relieves stress, prevents the formation of cracks and peeling of the plaster from the wall surface.

These phenomena result from the following factors:
  1. a large difference in ambient temperatures;
  2. high humidity and its fluctuations;
  3. water penetration into the plaster layer during rain or melting of ice and snow;
  4. shock and other mechanical effects.

The use of reinforcing nets and methods of its use is regulated by SNiP 3.04.01-87.
  This document establishes general requirements for exterior and interior surfaces that are to be treated. The maximum possible thickness of one layer of plaster should not exceed 15 mm for cement-sand and lime colloidal solutions. For coatings with a gypsum binder component, this indicator should not exceed 20 mm.
  Reinforcing mesh is used in the process and external and internal works. Strengthening the plaster layer is carried out when applying it on brick, stone and solid walls.
Ways of attaching nets to surfaces   as well as their appearance for this particular structure is established by the project documentation. One of the factors determining the choice of a material is price.

Reinforcement Mesh Classification

The building materials industry offers consumers an extensive range of products of this type.
  The classification of reinforcement networks for finishing works is carried out according to various criteria, and in particular:
  1. by material: steel, fiberglass and polymers;
  2. according to the method of manufacture: cut-through, welded, braided and others;
  3. by cell size or density.

Low carbon galvanized steel has the same coefficient of thermal expansion as concrete. This circumstance determines the use of this material for the manufacture of reinforcing nets.
Even with significant fluctuations in temperature in the places of collision of steel and plaster there is no additional stress, which can later lead to destructive phenomena.
  One of the most inexpensive types of mesh is expanded metal, which is made from metal sheet with a thickness of 0.35-0.55 mm. On special equipment, a through-cutting of straight holes in a checkerboard pattern is made.
  At the next stage, the sheet is stretched, the mesh is formed and rolled up into rolls. Product width - 1 m with a length of 10 m in one packaging unit.
  The production of reinforcing meshes for plastering walls and other building structures is organized in accordance with GOST R 52751-2007 and GOST 3826-82. Regulatory documentation determines the methods of packaging products and labeling, as well as the conditions of transportation and storage. Leaving the steel or composite mesh for a long time in the open is not recommended.

The use of reinforcing materials

Plastering works from external or internal surfaces of walls are carried out under certain conditions. In premises, for example, windows and doors must be installed, and in winter heating devices are turned on.
  When performing outdoor treatment, the ambient air temperature should be in the range of +8 to + 35 ° C, and the surfaces should be protected from heavy rainfall and direct sunlight.
  When performing works on plastering the surface of the walls with your own hands, the need for the use of reinforcing materials is first determined. To do this, conducted her careful examination and examination. Parameters of deviations of a wall from a plane in horizontal and vertical position are established with the help of a steel or aluminum lath with a length of at least two meters.
  The instruction prescribes measuring at least five places with one position of the rails. If the measurement results exceed 20 mm, the use of a reinforcing mesh is necessary.

Other indications for strengthening the layer of plaster or putty:

1. finishing work is carried out on the insulation: polystyrene foam or foam;
  2. the load-bearing wall did not take full load, the construction of the upper floors was not completed;
  3. The construction has been erected relatively recently and the shrinkage process has not yet ended.
  The choice of reinforcing mesh is determined by the thickness of the intended layer of plaster. So, if this parameter does not exceed 30 mm, it is recommended to use a mesh of polymers or composites.
If the thickness of the plaster is up to 50 mm, a steel braided or welded reinforcing fabric will be required. With large deviations, it is better to refuse to apply sand-cement or gypsum solutions.

Calculation of the required amount of materials and tools

To ensure the work with all the necessary pre-made mesh and fastening. The calculation of the need for materials is carried out on the basis of the measurement of the wall or its section where it is supposed to strengthen the facing layer.
  When purchasing materials, you should purchase a grid with a small margin of 5-10% in order to compensate for the overlap between the sheets.
  For the installation of a reinforcing coating in brick, stone, aerated concrete masonry are needed:
  hammer drill with a set of drills for concrete or perforator;
  hammer;
  cordless or network screwdriver;
  screwdriver.
  Fastening of the mesh is carried out with the help of sets of the type of fast assembly and steel washers with an outer diameter of 20-25 mm. The use of this method of installation provides sufficient adhesion of the plaster with the wall and virtually eliminates the possibility of its detachment.

Fixing mesh reinforcement method of indentation

This method is good, above all, low cost and does not require additional costs for fasteners.
  It is executed in the following order:
  1. The first layer of plaster or putty is applied on the prepared wall;
  2. a grid with a reinforcing material is applied to the non-frozen coating;
  3. using a spatula or trowel, it is pressed into the nakryvochny layer until it is completely drowned;
  4. plaster is leveled and remains at rest until complete drying.
  The described technology is good in relatively small areas and cannot be used with continuous surface reinforcement. It is difficult to achieve rapid application of plaster on large areas, followed by reinforcement.

Mounting the grid on the dowel nails

This method ensures high reliability of the connection of the plaster with the surface.
  Mounting plaster grid in this case is as follows:

1. A perforator or impact drill is used to make holes in the wall and plastic plugs get blocked in them;
  2. dowel-nails with put-on washers are screwed into them;
  3. mesh is mounted on the mounted fasteners;
  4. The screws tighten the screwdriver to the stop or get hammered.

Helpful advice: In preparation for mounting the grid, you must first install two fasteners along the edge of the wall. Intermediate points are performed every 0.5 - 0.6 m in staggered order over the entire surface of the reinforcing coating. Be sure to have mounting in places overlap sheets.

Reliable fastening of the mesh for plaster will allow to avoid premature destruction of the treatment under the influence of external factors and internal stresses. This preparatory operation is not distinguished by high complexity and is quite qualitatively carried out on its own. Familiarization with the video in this article will allow a person with minimal skills to do everything on their own.

Anyone who has been decorating the walls knows that when applying a thick layer of plaster, the material may not withstand its own weight and begin to peel off from the surface of the wall. To prevent this from happening, a reinforcing mesh is used. It is fixed on the wall and takes on some of the load.

When do you need a grid

If wall plastering is done without a mesh, there is a chance that the material will peel off under its own weight. Thanks to the reinforcing mesh, a monolithic slab is created that can withstand any loads. For plaster of different thickness, different grids are created, designed for a specific load.

The use of the grid makes it possible to form a durable layer of the solution, on which even with prolonged use of the room no cracks will appear. This result can not be achieved without the use of the described products.

It should be noted that even with incorrect mixing or non-observance of the temperature level, the grid helps to preserve the integrity of the plaster. There are special nets for the facade that are not subject to corrosion.

Types of grids

In the market of building materials you can find many varieties of nets, which are applied plaster. In order not to be mistaken during the selection, it is worth considering the main types of such products and their features:

To choose from the options, it is enough to determine in what conditions the grid will be used. If you need to plaster the facade, it is better to buy metal or fiberglass products with large cells. When applying the compositions on the inner walls, you can use plastic mesh.

How is stucco

To understand how to properly fix the mesh on the wall, it is worth considering the two most popular types of mesh - glass cloth and metal. It is much easier to fasten the first named type of products, since for this it is only necessary to screw in several screws at an equal distance from each other. It is enough such fastenings for reliable deduction of a grid.

To keep the net more secure, you should roll it across the entire width in one piece, without dividing the product into several. At a distance of about two meters from each other during installation, vertical beacons are installed. After the net is suspended from the screws, the plaster applied to it seals it against the wall, so no additional fastening elements are needed.

The installation process of metal mesh is somewhat different. This is due to the fact that under its own weight such a product is not able to reliably hold on to the mounts. Also, the cells of metal grids are large and need additional fastening with a mounting tape.

For fixing, you only need to cut off a part of the mounting tape so that it can completely close one cell. After cutting the mounting tape, it is fixed to the wall with screws. It is necessary to calculate the distance between the fixings so that the grid does not sag on any part of the wall.

Surface preparation

Before you begin plastering the walls, you must clean the surface of dirt and old finishing materials. After finishing works, there should not be any additional materials on the surface, since they can cause the plaster to peel off.

After cleaning the surface of the walls must be applied primer. Such compounds increase the strength of the wall and improve the quality of adhesion. They also prevent mold and corrosion. The primer contributes to the rapid drying of the surface and contributes to a better absorption of the compositions that are applied after it.

Plastering

After preparing the surface and fixing the reinforcing mesh on it, plaster is applied in several layers. To properly apply the composition to the surface, you should consider the features of creating different layers:

The first layer. Plaster is usually applied in two or three layers, depending on the wall material. On concrete, for example, it is necessary to apply three layers. The first of them is called "splashing". Plaster at this stage has a creamy consistency and pounces on the surface of the wall in any order. The composition may be smeared, but throwing speeds up the process. After applying the plaster to a specific area of \u200b\u200bthe wall you need to rinse the tool. After throwing, the composition is leveled with a two-handed trowel from bottom to top.

The second layer. After the first layer is completely dry, you need to knead the plaster, the consistency of which should resemble the dough. Then you need to throw the composition on the wall and, taking the taster, smear it in a horizontal and vertical direction. After applying the second layer, the reinforcing mesh is completely covered with plaster. If it still protrudes on the surface, you need to apply the plaster again.

The third layer. At this stage it is necessary to level the composition more accurately so that there are no errors on the surface of the walls. Moisturize the surface of the plaster before applying the finishing layer.

This technology of plastering with a grid is universal and can be used when working with walls of various materials.

The final stage of work

After the plaster is completely dry, it must be prepared to fix the finishing materials. For painting and gluing wallpaper, it is enough to sand the surface with sandpaper. If there are noticeable irregularities on the wall, you need to start using the largest brand of paper. For convenience, the segment of the product is clamped on a grater. Grinding is performed in circular motions with little effort, so as not to make new defects on the surface.

When the wall becomes homogeneous, you need to change the brand and continue to grout. If the surface is painted, you need to take the paper P120. During the whole process it is worth using glasses and a respirator to protect against dust.

Since it is quite difficult to grind the surface in the corners, it is worth working either without a grater or using bars with sharp corners. If you want to facilitate and speed up the process of work, you can purchase an electric grater. But for processing the walls of one apartment to buy such a product is unprofitable. After grinding, remove the dust with a brush.

Putting plaster for wallpaper and painting

Before starting work, you should determine how the room will look like and what will be used as finishing materials. If the wallpaper is selected, you need to determine in advance their type and thickness. If they are thin, you need to apply several layers of leveling plaster. This will allow to glue the wallpaper without irregularities and bubbles.

For the room in which the wallpaper will be hung, it is better to buy ready-made dry mixtures, since using them you can make better plaster.

If, however, plastering of the wall surface occurs before painting, it is necessary to carefully prepare the wall, not leaving even small irregularities on it. The whole process is carried out in several stages:

• at first thinly leveling layer is applied;
• then, if necessary, two more layers are applied to eliminate defects;

When finishing ceilings and walls, plaster and a grid for plaster are often used.

Plaster may not always lie perfectly on the surface. In order for the layer of plaster stuck better, you can use a plaster grid.

Previously, wooden shing (for wooden surfaces) was used for these purposes, the brick was plastered without preparation - its roughness and joints were a sufficient condition for good adhesion of the plaster layer to the wall.

Scope and characteristic

Grid under the plaster is used to keep the plaster layer firmly. The fact is that even with a carefully prepared surface under the plaster, the solution can sometimes go wrong, as needed. This may occur if some errors are made during plastering: non-compliance with proportions, temperature and humidity levels in the room ...

In order to avoid such mistakes, it is necessary to use plaster meshes, due to which the negative effects of plastering are minimized. These nets are designed to take on the burden that may arise from improper use of the room.

Grids are used for the reinforcement of walls before painting (wallpapering). The grid gives the plaster the greatest strength, increasing the service life. The use of grids for walls with significant defects is especially appreciated when it is necessary to apply plaster with a thick layer.

Before you buy a grid for plaster, you must choose the one that is suitable for a particular job.

Types of mesh

There are many types of mesh for plaster. When choosing the one that is needed for certain works, you need to focus on the features of the type of grid and the size of its cells.

There are types of mesh:

• Masonry net. It is made of a polymeric substance. The size of each cell in the grid is 5x5 millimeters. Used for masonry.

• Mesh wagon made of polyurethane. Used for plastering and decorating. There are types of universal wagon: small - cell size 6x6, medium - 13x15 and large - 22x35.

• Fiberglass. It is made of fiberglass, which is specially processed. Cell size - 5x5 mm. This mesh is particularly durable and resistant to various temperatures and chemical attack. It is widely used. / Li\u003e

• Plurima. This mesh is made of polypropylene. Cell size - 5x6 mm. It has chemical inertness. It is used for interior and exterior decorating.

• Armaflex. It is made of polypropylene and has reinforced components. Cell size - 12x15. Used when plastering the surface with a thick layer.

• Sintoflex. Also consists of polypropylene. The dimensions of the cells are 12x14 and 22x35. Suitable for interior and exterior decorating.

• Steel mesh. The basis of this grid - steel rods, which are brazed in knots. There is a wide range of cell sizes.

• Metal grid. Cell sizes are different. It is used only for finishing work inside the building.

• Galvanized mesh. It is made of galvanized rods that are brazed in knots. Cell sizes may vary. Differs in the high durability and durability. It is applied to external and internal finishing works.

Which one to choose?

When choosing a plaster grid, you need to pay attention to what type of work you are going to perform. That is, you need to know the thickness of the layer of future plaster. Namely:

• With the required thickness of the plaster layer up to 20 mm, the grid can not be used at all.

• In the presence of rust and the required thickness of the plaster layer from 20 to 30 mm. The most acceptable would be the use of glass cloth mesh.

• With a thickness of plaster of 30 mm. It is necessary to use metal mesh.

• If it is necessary to finish the uneven ceiling, in which the height difference is 50 mm, it is better to abandon plastering at all, replacing the plaster with a suspended or suspended ceiling. So it will be much easier and cheaper.

Decide on your choice, and let all the finishing work be done perfectly.

The facade is one of the most important building operations. Exterior walls are exposed to precipitation, cyclic freezing / thawing and harsh ultraviolet rays. Such difficult operating conditions place high demands on the quality of finishes. Eliminating defects on the facade walls is very expensive and time consuming. We'll have to install scaffolding, wait for good weather, clean up construction waste. To eliminate the appearance of unpleasant situations, it is necessary to take all measures to prevent them.

Finishing of facade walls 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 metal grid of galvanized wire.

Full Metal Mesh

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

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

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

Not to improve the fixation of the adhesive to the surface of polystyrene foam and to prevent cracks, as some “sofa” builders say, namely for mechanical protection.

Why do we say that? The surface of expanded polystyrene is protected from the negative effects of ultraviolet rays and, oddly enough, damage by birds. For some unknown reason, birds like to peck foam very much, if left unprotected, then soon there will be many large and small indentations on the surface. Conclusion - polystyrene need to close. 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 affect their actual performance. The fact is that even the thinnest layer of glue or another cement-sand mixture does not completely transmit ultraviolet rays. Why should a consumer pay for those properties that he does not need? And one more nuance. Most often, builders fix the reinforcing mesh on the entire wall. We think that this is done either by ignorance of physical properties, or by the desire to earn more. We recommend using a reinforcing mesh to a height of 1.5–2.0 meters, there is no need above. No one will so high damage the finish screed on the foam. Mechanical damage occurs due to various blows, careless chores near the facade wall, etc.

Types of facade reinforcing nets

Facade reinforcing mesh made of galvanized wire or polymer. The first used for facade plaster, and the second universal use.

Modern facade mesh

Metal Mesh Fixation Technology

Metal nets are used only for cement-sand facade plasters, foam insulation does not work them out. The reason - a small thickness of the screed on the foam plates. A metal grid can not be leveled with such precision, it must be pressed against a thick layer of mortar. Metal facade reinforcing mesh capable of withstanding great efforts, is applied, if necessary, applying a thick layer of plaster on an uneven base.

The algorithm of its fixation has several features, the implementation of which guarantees the obtaining of the expected effect. Laying the grid can be both vertical and horizontal stripes. For the strength of the plaster it does not matter, decide for yourself how you prefer to work. How to fix the metal grid to the front wall?

Step 1. Remove the dimensions of the wall, cut on them a metal grid. Choose a cutting tool according to the wire diameter. Universal tool - scissors for metal.

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

Step 2.   The metal grid can be fixed with dowels, the length of the hardware should provide a strong fixation. Ordinary nails 80–90 mm long can be used for foam concrete facade walls. They are easily hammered into blocks with an ordinary hammer, it is much faster and easier to work with them. 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.   Drill the first hole under the grid with a power drill with a perforator. The depth of the holes should be several centimeters longer than the length of the plastic part. Otherwise, it is impossible to insert the dowel to the desired depth - the hole is slightly filled with brick chips during drilling and reduces its effective depth. Remove it from there is difficult, it is better to drill more.

Important. The height of the protruding part of the dowels should not exceed the thickness of the plaster. Watch out for this parameter on the entire area of \u200b\u200bthe facade wall so that during plastering you do not have to fix the dowels.

Step 4.   Drill holes in a single line at a distance of about fifty centimeters, hang a grid 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 is uneven, then re-hang the grid on the adjacent cells.

Mounting plaster grid - scheme

Step 6.   Everything is normal - continue to fix the grid, install the dowels in a checkerboard pattern. Most metal nets have a width of one meter, for fixing you will need three rows of hardware.

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

Step 7.   In the field of window and door openings the grid is cut to size. But there is nothing terrible if you do not cut it off, but simply bend it. Just make sure that the edges of the bent sections do not protrude beyond the thickness of the plaster layer.

During the plastering of such a facade wall, the solution needs to be thrown in several stages. For the first time, the mass should be slightly thicker than for the final alignment. Specific values \u200b\u200bdepend on several indicators and are determined individually, taking into account the practical experience of the master. The consistency of the solution is influenced by the weather, the ability of the front 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 depends on the correctness of the implementation of recommendations for the installation of plastic reinforcing mesh on the 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.

For gluing the mesh suitable glue of any brand. Study the instructions, it should have high adhesion with plastic materials. In most cases, a finishing layer of glue several millimeters thick is applied on the plastic reinforcing mesh. The topcoat is made with facade paints or a thin layer of decorative plaster.

Step 1.   Inspect the surface of the plates. If they were fixed with dowels, then completely drown the caps and close the grooves. At the same time, you can close the gap, but this is not necessary. The fact is that the gaps will automatically close during the application of the first layer.

Step 2.   On the wall, draw a horizontal line along the height of the reinforcing layer. It will help monitor the height of the adhesive. A thin layer of material dries quickly, and this becomes not only the reason for the increase in material consumption, but also adversely affects the final alignment of the layer for painting.

Step 3.   Prepare the glue 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 interfere manually with a trowel or with a mixing nozzle to an electric drill.

The second method is not only easier, but more effective. Stir for a few minutes, and then leave the mixture to stand for another 5-6 minutes. During this time, the moisture is evenly distributed throughout the 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, for beginners, you can first use shorter ones.

Practical advice. If you are just learning to apply glue to the surface, then it is better to get used to working with both hands right away. There will be one - connect the second hand. Believe me, this is not so difficult, you just need to show a little bit of endurance and patience.

Apply glue to the trowel with a trowel in the center of the tool. The quantity will be determined by practical consideration. While laying the layer, keep the spatula at an angle to the foam plates, press down with medium force. Achieve a layer thickness of about 2–3 millimeters. Do not immediately prepare a large amount of surface, for beginners it is enough two meters per din. If you do not have time to fix the grid - 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 reinforcing mesh. If it does not fit into the window opening, trim the material.

Step 6. Glue one end of the grid, align it horizontally to the length of the prepared section of the wall. Make sure that the grid lays down smoothly without distortions and bends, orient yourself to the previously drawn line on the foam.

Practical advice. The grid should lie with an overlap of about ten centimeters. It is possible to meet the recommendations of the place of overlap of one line with glue not to smear, but to do it simultaneously for two rows. We do not advise to do so, it only complicates the work. Glue the first row of the grid across the entire width, including the place of the overlap. The second line is glued on top of the freshly applied glue. This method simplifies the fixation of the mesh and has a positive effect on quality.

Step 7.   Hand press the net to fresh glue in several places, check its position again.

Step 8.   Spatula start to press the grid to the surface of the insulation. Carefully ensure that the glue of the first layer protrudes over the entire surface and evenly covers the mesh cells on the front side. If there are places with insufficient glue thickness, re-apply it over the reinforcing mesh. Such passes may appear to inexperienced masters. Over time, you will learn by eye to determine the optimal thickness of the adhesive and the gaps will no longer be. Spread excess mortar over loose surfaces. You should not try to immediately make the surface perfectly flat, but strive for this result is necessary.

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

That's all the technology, the surface of the front wall is prepared for painting or finishing with other materials. Once again we remind that the plastic reinforcing mesh on the warmed facades is not used to prevent cracks on the surface of the adhesive, 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 procedures during construction work on high-rise buildings is one of the main requirements for all developers. This is especially true of objects being built within cities. The front mesh is fixed on the scaffolding and prevents falling debris and tools on the pedestrian walkways. For such purposes, the cheapest of reinforcing plastic mesh is used, after dismantling it is suitable for direct use.

"Emerald" - a new grid for scaffolding

Question answer

Is it possible to repair detached areas with reinforced facade mesh? It is possible, but it is better not to allow such situations. Unfortunately, in most cases, detachments appear after a few months or years after the finishing of the warmed facade walls.

How is the repair done?

1. Revise the delaminated area. Hand, check the strength of fixing the mesh near 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 peeling off the grid towards you and use a sharp mounting knife to cut it around the perimeter. Be very careful not to damage the foam. If during the cutting the sect continues to flake off - great. In this way you are shooting the entire problem area, it would in any case peel off over time.
3. Cut a new grid for the patch, the size should slightly exceed the freed area for the overlap.
4. From the surface of the foam, remove the layer of old glue.
5. Using a spatula, carefully remove the top layer of adhesive from the surface of the remaining mesh to the width of the new overlap. Apply the first layer of glue, drown the mesh in it and apply a second layer of glue.
6. After it dries, line it up. Pay special attention to the junction. It should be as smooth as possible without sudden changes in height.

How does the quality of plastic mesh depend on its price? Almost nothing. When you select a mesh, pay attention to the web thickness and mesh size. All other characteristics are nothing more than advertising tricks manufacturers.

The better plastic anti-corrosion coating of metal mesh from galvanizing? Nothing, moreover, the price of such a grid is higher than with galvanized wire. You need to know that the adhesion of all cement mortars to plastics is much lower than to galvanized surfaces. As for the service life and carrying capacity, these figures are absolutely identical.

Is it possible to do without a reinforcing mesh when plastering uneven facade walls? Not only possible, but necessary. We have already talked about simpler and more efficient methods of working with such surfaces. Metal mesh reinforcement is not used to prevent cracking, but to increase the bearing capacity of cement-sand mortars. It is needed during the floor screed. Another nuance. Indicators of linear thermal expansion of the metal and the solution are significantly different. This means that microcracks will surely appear at the places where the cement and the metal mesh abut, because the temperatures vary widely in the street. In closed rooms there is no such fluctuations.

Whether to use a reinforcing mesh on the basement surfaces of the facade walls? Use this technology only for foam insulated base. In all other cases, it is not needed.

How much increases the cost of finishing the facade walls in connection with the use of reinforcing mesh? The cost of finishing increases by no more than 3-5%. But if we take into account possible repairs due to mechanical damage to the foam, then a slight increase in cost is fully justified.
