How to plaster walls with mesh. Facade plastering on a grid: advice from experts. What is the mesh for plastering interior walls

Plaster is one of the most famous types of wall decoration. In order for the solution to last a long time and provide strength, it must be reinforced with a special mesh. In this article, we will take a closer look at the types of reinforcing meshes and tell you how to install them correctly.

Types of plaster meshes

Grids for wall plastering can be made of metal or polyurethane. They are glued to the wall with glue, self-tapping screws or screws. The canvas is sold in special rolls and has different dimensions, depending on the area of ​​\u200b\u200bthe wall that is being plastered.

There are a huge number of types of plaster meshes for plastering walls. Let's look at the main ones:

How to apply plaster

Depending on the method of applying the plaster, the reinforcing mesh can be fixed in various ways. The first plaster layer is reinforced on top of the mixture, while it needs to be slightly pressed into the wall.

Advice! Before applying the last layer, we recommend fixing the mesh with special tools. If the area of ​​the wall to be treated is not too large, the mortar itself can be used as a fastener. To do this, apply the mixture at the attachment points, the entire wall does not need to be processed.

Which is better to choose

When choosing a reinforcing material for walls, first of all, evaluate the thickness of the future layer of plaster. You need to choose from the following options:

Plastic variant

When purchasing it for a wall, remember that the density must be more than 110 grams per square meter and alkali resistant. The minimum layer thickness is 3 mm and the maximum is twenty. Before proceeding to work, the rolls must be cut according to the area of ​​\u200b\u200bthe wall. They depend on the chosen placement method - along or across. If there are defects on the wall, it is better to place the material along the seams of the mortar. Make sure that the entire surface area is covered. It is better to trim with a margin of ten centimeters in order to further strengthen the seams.

Plastic Mesh Attachment Technique

The first step is to apply the first layer of plaster on the wall. Next, a plastic mesh is already superimposed, while it needs to be pressed as hard as possible. Then a second layer of plaster is applied. It is not necessary to wait for drying, plastering can be continued immediately. The plastic mesh should be placed in the middle of the wall. It can also be used for exterior wall decoration.

Most often, screws or brackets are used for mounting on the wall, and then they are already processed. But this method is only suitable for a thin layer of plaster. In this case, the grid will be located exactly in the middle. If the thickness is more than 10 mm, then it should be applied to the hats of pre-installed beacons. In this case, adjacent canvases will need to be placed with an overlap of 10 mm. And only after that it will be possible to continue plastering the wall surface.

When working with a plastic mesh, the plaster must be applied evenly. In this case, it is better to start from the middle of the wall, distributing the mixture in different directions. We recommend pressing the corners with a rule or a wide spatula.

Working with a metal structure

This option is used if it is planned to apply plaster more than 30 mm. The material is distinguished by its light weight, easy installation and, despite the metal base, quite good protection against rust. But, unfortunately, for outdoor work, the installation of such a canvas is not suitable.

First of all, the metal mesh will need to be degreased. To do this, it can be washed with water or simply rubbed with a damp cloth. The installation process consists of the following steps:

It will be necessary to apply the solution twice, and it will be possible to continue only after the first stage of the plaster has completely dried. It is applied using a trowel, the plaster is pressed into the mesh so that the mixture reaches the very wall. Then it is distributed over the entire plane of the wall with a spatula.

Plaster mesh netting

The chain-link mesh, or as it is also called braided, has a design with a cell diameter of two centimeters. This canvas is mainly used for reinforcing large areas or facades of the house. At the same time, the chain-link is perfect for outdoor work, due to its materials it is well protected from weather influences. The method of mounting on the walls is no different from the metal installation. It is light enough that even a beginner can easily cope with such work.

Conclusion

As you can see, the reinforcing mesh has a positive effect on strengthening the wall surface. It will protect the plaster from possible peeling. This material can be used for both internal and external work. The installation itself will not take much time and effort, because the process is quite easy. The main thing is to follow the instructions given in the article, and the result will not be long in coming. We recommend watching the tutorial video:

Plaster mesh is a versatile material. This tool is used in various areas of construction and repair. The effectiveness of individual types of plaster meshes is determined by the materials of their manufacture and design features.

Purpose

First of all, a plaster mesh is used for outdoor work. After all, it is the outer facing layer that lends itself to the most significant influences of environmental factors.

The use of the material contributes to the creation of a textured relief, which serves as the basis for a solid laying of the leveling plaster layer. The presence of a cellular structure makes it possible to effectively bind the particles of the solution. This makes it possible to form a solid monolithic surface.

Plaster mesh allows you to plaster the walls with high quality even for those masters who are engaged in such work for the first time. At the same time, the highest mortar setting rates are achieved as a result of reliable laying of the cladding on the textured mesh surface.

Areas of use

Currently, the plaster mesh is actively used:

• as a reinforced layer when performing facing works;
• when installing underfloor heating systems;
• to strengthen reinforced concrete structures;
• if necessary, create protection for mechanisms and machines;
• in the construction of enclosures, barriers.

Material selection

The main criterion in the selection of plaster mesh is the required thickness of the facing layer. Based on this, you should stop at one of the following options:

1. In cases where the plaster layer has a thickness of up to 20 mm, it is quite possible to reliably veneer the surfaces without the use of a plaster mesh.
2. If the facing layer in the form of plaster is about 20-30 mm, in this case it is advisable to fasten the plaster stack of fiberglass. The main purpose of such products is to create a protective layer that protects surfaces from cracking.
3. Laying plaster with a layer of more than 30 mm necessarily requires the use of a metal plaster mesh. This solution protects the facing layer from flaking.
4. In the presence of the most uneven surfaces with recesses, where the differences in the facing layer are more than 50 mm, it is recommended to completely abandon the plastering.

Installation of metal reinforcing mesh

Metal plaster stack is the most common option when it is necessary to create the most reliable reinforcing surface. For laying such a grid, you will need construction dowels, self-tapping screws and a specialized galvanized mounting tape.

Before the plaster mesh for interior work is laid on the surface, preparation of the latter is required. The material is cut from rolls according to the desired dimensions. Next, the grid is degreased with acetone or a solvent.

It is recommended to fasten the plaster mesh starting from the ceiling. The upper side of the canvas is fixed with self-tapping screws along the entire length. Under each cap of the self-tapping screw, a piece of galvanized mounting tape is preliminarily placed. Widened washers can serve as a worthy alternative to the tape. However, this solution cannot be called profitable in terms of cost savings.

Holes are drilled in the surface of the wall, where plastic dowels are installed. Such fasteners are mounted in a checkerboard pattern over the entire area for reinforcement with a distance of about 40-50 cm. At the joints, the plaster mesh for interior work should be on the next canvas with an overlap of about 8-10 cm.

Laying fiberglass reinforcing mesh

The process of installing a fiberglass plaster mesh is an order of magnitude easier compared to fixing a metal reinforcing base. To securely fix the fiberglass plaster mesh on the desired surface, it is enough to use self-tapping screws. With the help of such fasteners, the upper edge of the mesh is first processed, and then the entire perimeter of the reinforcing material.

Usually, when installing a fiberglass plaster mesh, no additional fixation is required. When laying the plaster layer, the reinforcing material is fixed by the thickness of the cladding.

It is worth noting that it is most convenient to unwind the rolls of material and fix the canvases parallel to the floor plane along the wall. Installation of fiberglass plaster mesh is best to start from one of the upper corners. As in the case of laying a metal mesh, it is necessary to create a slight overlap of individual canvases.

As practice shows, the highest strength of the reinforcing coating is achieved when laying the mesh in solid sheets along the entire length of the treated surface. Therefore, when cutting the material, it is necessary to try to create a minimum number of small individual pieces.

The mesh increases the strength of the solution when applied to large areas and transitions between different wall materials. Plastering the facade along the grid is necessary when working in new buildings, the walls of which are still sagging.

The reinforcing material can be metal, polymer or fiberglass. Its choice depends on the application.

What can be a grid

Often applied to concrete, brick and wood facades, the finish cracks and flakes off. To prevent this from happening, the surfaces are reinforced with a mesh.

Woven

Woven mesh. This is a thin, but strong and flexible material, woven by weaving from wire of various sections. a grid with square cells 1 × 1 cm and a zinc coating. Sold in rolls.

chain link

A woven mesh or netting has a cell diameter of 2 cm, used to strengthen significant layers.

Types of metal meshes

Welded

Welded mesh has square cells. It is produced by spot welding of the intersections of the wire, the bars of which are perpendicular to each other. The material is galvanized or polymer-coated light low-carbon wire. A welded mesh is used to prevent cracking of the finish during active precipitation. We recommend using a grid with cells of 2-3 cm.

expanded metal

It is made on a special press from sheets of metal. The resulting material has diamond-shaped cells, which are staggered. Used for relatively. The rolls are 1m wide.

With a sufficiently thin layer of plaster, a mesh of fiberglass or polymers is used.

Facade plastering

Polymer mesh (price - from 2150 rubles)

Use a metal mesh when applying a finishing layer of 3 cm or more. The chain-link is not yet used for reinforcement.

Unroll the mesh roll. Measure the height of the surface from the roof to the ground with a tape measure. Cut the desired number of panels with scissors for metal.

Straighten and fix the mesh with screws or nails on the primed surface so that adjacent sheets overlap by 10 cm.

Mix the solution with an antiseptic. The latter will ensure that mold spots do not appear on the surface.

Throw the first primer layer of the solution with a spatula or trowel and level it with a rule. Let the mixture dry and apply a second leveling coat. It is thinner, so spread it with a trowel or large spatula.

If the mass lay unevenly, after it has completely dried, we recommend using a finishing putty. When it hardens, correct the bumps with a fine sandpaper.

Polymer mesh is often used. It is resistant to chemical influences, so it does not spoil the finish coating during operation.

Measure with a tape measure and cut the mesh webs. If the base is dense, apply a thin layer of mortar and press the reinforcing material into it. If the walls are porous or wooden, you can fix the mesh with a stapler.

After fixing it, evenly distribute the mass over its entire surface so that the network does not look out.

Grid plastering - technology for working with polymers:

Start applying the solution from the middle of the canvas and continue to its edges, as if you were gluing wallpaper and expelling air from under them.

Note! Polymer meshes are elastic, so they stretch. Work carefully and do not allow the formation of bubbles from the reinforcement material.

Facing trim

The most common method of applying a top coat to both interior and exterior is to paint them. Before work, evaluate the quality of the base, repair cracks if necessary, make sure that the layer has a strong bond with the surface, does not peel off and putty the walls.

• After the putty has hardened, sand the surfaces with sandpaper. Before painting with adhesive paint, treat the area with a water-based primer. Pay special attention to the question of how to paint the plaster.

Note! If the finish is fresh, it may have an excess of alkali, so the use of solvent-based formulations is undesirable. When using organic solvent paints, be aware that the surface must be protected with a synthetic primer.

• Paint with a roller, carefully and without gaps, processing the entire surface. After the first coat of paint has dried, apply the second.

Advice on how to paint the facade plaster. It is better to use alkyd, acrylic and latex compounds for this purpose.

• Indoors, the second most popular finish is wallpaper, which also requires careful preparation.
• Remove old wallpaper, if any. Before, make sure that it is firmly held.
• Rinse the cleaned surface with water and inspect for cracks. If necessary, cover with putty.
• Level the treated areas with sandpaper.
• Prepare wallpaper paste.

The rolls always have instructions for gluing the material and recommendations for the selection of glue. The technique of working with wallpaper on plastered walls does not differ from similar operations on other surfaces.

Repairs are often accompanied by leveling the walls with plaster. In addition, it also improves thermal insulation, reduces the level of extraneous noise in the finished room. Surfaces plastered with decorative mixtures have a beautiful appearance. When the irregularities are small and there are practically no defects, then the solution is often applied simply to the prepared base. If the deviations are large, there are cracks, then a plaster mesh is necessarily used in the work to reinforce the walls. It is represented by a wide range, which allows you to choose products for certain operating conditions.

Scope of use

Reinforcing mesh for wall plastering has replaced the old methods (shingles, stuffed nails) used to improve the adhesion of the finishing layer to the base surface. It is made from materials with different properties. There are products from a large number of different manufacturers on the market.

It is used both for internal, and external works. It is the basis of the leveling coating. The latter becomes stronger and more durable as a result. The mesh must be used to avoid the appearance of delamination, cracking, or to stop the process of crack growth itself.

The construction mesh for plaster is used to qualitatively prepare the base for further activities to decorate work surfaces. With proper installation and further plastering, it prolongs the life of the finish and helps maintain the integrity of the partitions.

Types of plaster mesh

Reinforced mesh for plaster differs in the materials used for its production, the structure and size of the cells, and the methods of creation. According to the first criterion, the following varieties are distinguished:

• plastic;

Products have all the advantages and disadvantages of the materials used for their production.

A more detailed classification is presented in the table below.

The existing assortment allows you to choose high-quality products, taking into account all requirements. The use of material that meets the existing conditions determines the durability of the finish.

Choice of working material

The main determining factor in the selection of material is its suitability for specific conditions, so the mesh for wall plastering is selected taking into account the following number of factors:

• the required thickness of the created finishing coating;
• the type of plaster mixture that is used;
• type of base (concrete, wood, brick, porous materials, stone);
• external conditions in which the formed plaster layer will be located: outside the building, inside, or in unheated, damp rooms.

Plaster with the following types of mixtures:

• cement-lime;
• plaster;
• cement-sand;
• clay and others.

Various additives are often added to such compositions. Together with the main components, they have a certain level of chemical activity. This determines the degree of their influence on different materials from which the meshes for reinforcement are made.

Taking into account the above provisions, the main recommendations for choosing a mesh for plastering walls are as follows:

• fiberglass products are recommended to be used when the thickness of the created plaster layer is up to 3 cm, when there are also recesses, cracks in order to stop the expansion of old ones and the formation of new ones;
• if the height of the formed coating exceeds 3 cm, then a more appropriate option would be from metal: it is able to withstand the weight of the finish and not peel off at the same time;
• plastic products are best used for thin gypsum mortars, and, for example, cement-sand compositions corrode such reinforcing material over time;
• when using mixtures based on clay, also when there are significant irregularities on the surface of the base, metal options are relevant;
• plastic sheets with small cell sizes (for example, 0.2-0.3 cm) are used during finishing puttying;
• fiberglass or galvanized (ordinary metal ones are not suitable), products are a good way to reinforce rooms with high humidity;
• when there is a need to plaster the oven with a cement-clay mortar, then you can use a chain-link, and with a thin layer of it - fiberglass;
• steel products are suitable for joint use with compounds containing cement;
• during the plastering work on the exterior walls of the house, material with cells of 3 * 3 cm is usually used, and their larger sizes are selected to tighten the surface;
• for internal work, they mainly use material in rolls, and for external work, in the form of sections.

When the height of the created layer of plaster does not exceed 2 cm, then reinforcement can be omitted. Following the above recommendations will allow you to choose the most practical material.

Features of mounting different types of mesh

Metal mesh for plaster, fiberglass or plastic, can be mounted using different methods. The choice of fixing option is determined by the composition of the working mixture, the material from which the mesh is made, and the plastering technique used. Fix with:

• self-tapping screws or dowel-nails, screws.

The first layer of plaster for leveling the walls is reinforced by pressing the mesh into the mortar of the required thickness applied to the surface.

The best way to create a finishing coating (covering or decor) is to fix the adhesive web on a dry base with special fasteners.

When the area of ​​​​the area to be trimmed is small, then you can use the working mixture for fixing, applying it pointwise.

It is enough to simply fix the paint grid with a thin layer of mortar.

The fiberglass cloth is mounted according to the following optimal algorithm:

• perform markup for the installation of beacons;
• holes are drilled along it, into which dowels are then inserted;
• set the screw heads according to the level;
• apply the solution to an area equal to the width of the canvas used;
• a grid is immediately applied to the plaster, threading the caps from the screws through it;
• throw the mixture further;
• overlap (10 cm) fix the next strip;
• so continue until the entire room is reinforced;
• install beacons.

The solution should be smoothed over the canvas evenly, starting from the middle of the strip, while moving towards its edges. When creating a thin layer, fixing the fiberglass to the staples with further application of putty justifies itself.

The stucco metal mesh is fixed in the following sequence:

• cleaned of the lubricant composition by rinsing with water or wiping with a damp cloth;
• with scissors for metal, cut the canvas into pieces of the desired size;
• every 25-30 cm holes are drilled with a diameter of 6 mm for dowels (about 3 mm deeper than the length of the plastic part of the fastener), insert them;
• using screws and mounting tape - fix the material on the surface;
• the following fragments are laid with an overlap of 10 cm;
• install beacons.

The minimum height of the created coating depends on the thickness of the mesh wire. Metal products additionally strengthen the base, and fiberglass products reinforce the plaster with a mesh.

Methods for fixing the plaster mesh are discussed in detail in the video below.

Installation of facade fiberglass material is shown in the video below.

Strengthening the base, increasing the strength and reliability of the plaster finish - all this is ensured by the creation of an adhesive layer. It is formed using different materials.

For the correct implementation of the reinforcement of the walls with a mesh, it is necessary to take into account the type of mortar used, the place of installation (outside or inside the building), the expected height of the coating. It is also required to use suitable mounting technology. Compliance with the above conditions allows you to plaster walls or ceilings with high quality, minimize the possibility of cracking, and not be afraid of shrinkage at home.

Carrying out work on plastering surfaces is an important and responsible task. It is imperative to follow 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.

Reinforced mesh for plaster is best suited for solving 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, will allow the material to be securely fastened together. This approach is used when performing a large number of construction works, and it has proven itself only from the best side. So it is used everywhere and always satisfied with the result.

What is wall mesh?

Reinforcing mesh for wall plastering is fully consistent with its name and is a special product that has small cells that allow you to effectively contain the solution so that it does not scatter in different directions and stays on the wall as tightly as possible.

There are the following varieties:

• . masonry mesh, which has cells measuring 5x5 millimeters and is used with brick walls. It is made mainly from polymers;
• . universal mesh, which can have different cell 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 type of chemical attack, and also easily tolerates high loads that can be detrimental to other materials;
• . plurima mesh, made of polypropylene and having a light weight, which makes it easy to use without a strong increase in the load on the walls;
• . armaflex - polypropylene material with reinforced knots. It is used in those types of work where an increased level of load is expected;
• . syntoflex - has "immunity" to chemical and mechanical effects;
• . steel mesh - is one of the most durable models, but not suitable for outdoor use due to low resistance to precipitation;
• . galvanized mesh - is a modification of the previous model. With the help of a special treatment, it received protection against corrosion, so it is applicable for any purpose, including operation in conditions of high humidity.

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 goods that are beneficial to him, so it is better if the client himself understands the varieties.

How to choose a mesh for plastering work?

For inexperienced users, the question often arises, which mesh to reinforce the plaster with? Everything here 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 independently search for the necessary information. The right choice is very important for further operation, so you need to take it with all seriousness.

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

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

How to work with reinforcing mesh?

Reinforced plaster mesh must be securely and tightly attached to the wall so that it does not disturb the correct balance that will be established when the finish is completed. 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 quadrature of the wall being processed.
• . Further, holes are drilled with a drill and reinforcing mesh fasteners for plaster are inserted. They are quite standard screws, but with large diameter caps that will securely hold the mesh and press it against the wall.
• . Next, throw a base layer of plaster, without using a grid.
• . 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 load.
• . On top of the installed mesh, finishing work of the final level can be carried out. At the same time, the plaster will lay down evenly, and hold on without any problems. The main thing is to smooth 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 cell size, the correspondingly more expensive the cost of the material.
