Construction mesh for plaster. What kind of reinforcing mesh should be used for concrete, wallpaper, plaster according to technology - plastic, fiberglass or metal. Types of plaster mesh

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

Area of ​​use

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


Used for both interior and exterior work. It is the basis of the leveling coating. The latter as a result becomes stronger and more durable. The mesh should be used to avoid the appearance of peeling, cracking, or to stop the process of crack growth itself.

Construction mesh for plaster is used to qualitatively prepare the base for further measures to decorate work surfaces. At correct installation and further plastering, it extends the service 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 to produce them.

A more detailed classification is presented in the table below.

ViewCell size, mmCharacteristic
masonry (painting)5*5 plastic sheet used when working outside and inside buildings using gypsum mixtures
universal: small, medium, large6*6,
14*15,
22*35
the fine-mesh version is a suitable mesh for plastering interior walls, while the coarse-mesh version can withstand temperature changes and external loads well
fiberglass mesh5*5 durable, resistant to moisture, cold and heat, chemical compounds
Plurima5*6 made from polypropylene, chemically inert, used for external and interior work

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

Selection of working material

The main determining factor when selecting a material is its suitability for specific conditions, therefore the mesh for plastering walls is selected taking into account next row factors:

  • the required thickness of the created finishing coating;
  • the type of plaster mixture 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 using the following types of mixtures:

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

Various additives are often added to such compositions. They, together with the main components, have a certain level of chemical activity. Which determines the degree of their influence on different materials, from which the mesh for reinforcement is made.


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

  • It is recommended to use glass fabric products when the thickness of the created layer of plaster is up to 3 cm, when there are also depressions and cracks to stop the expansion of old ones and the formation of new ones;
  • if the height of the coating being formed exceeds 3 cm, then a more appropriate option would be metal: it can withstand the weight of the finish without peeling off;
  • It is better to use plastic products for gypsum mortars that are thin in thickness, and, for example, cement-sand compositions corrode such reinforcing material over time;
  • when using clay-based mixtures, 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 putty work;
  • fiberglass or galvanized (ordinary metal ones are not suitable), products are good way reinforce rooms with high humidity;
  • when there is a need to plaster the stove with a cement-clay mortar, then you can use chain-link, and if it is a thin layer, fiberglass;
  • steel products are suitable for joint use with compositions containing cement;
  • during the plastering works for finishing the external walls of a house, material with cells of 3*3 cm is usually used, and larger sizes are selected to tighten the surface;
  • For internal work, the material is mainly used 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 recommendations outlined above will allow you to choose the most practical material.

Features of installation of different types of mesh

Metal mesh for plaster, fiberglass or plastic, can be mounted using different ways. The choice of fastening 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 to level the walls is reinforced by pressing the mesh into the solution of the required thickness applied to the surface.

The optimal way to create finishing coating(covering or decor) is to secure the adhesive fabric to a dry base with special fasteners.

When the area to be finished is small, then you can use the working mixture for fixation, applying it pointwise.

The painting mesh is easy enough to fix thin layer solution.

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

  • carry out markings for the installation of beacons;
  • holes are drilled along it, into which dowels are then inserted;
  • align the screw heads according to the level;
  • apply the solution to an area equal to the width of the fabric used;
  • immediately apply a mesh to the plaster, threading screw heads through it;
  • add the mixture further;
  • overlap (10 cm) fix the next strip;
  • This continues until the entire room is reinforced;
  • install beacons.

The solution should be smoothed evenly over the canvas, starting from the middle of the strip, moving towards its edges. When creating a thin layer, it pays to secure fiberglass to staples and then apply putty.


The metal plaster mesh is attached in the following sequence:

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

Minimum height created coverage depends on the thickness of the mesh wire. Metal products additionally strengthen the base, and fiberglass products reinforce the plaster with mesh.

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

The installation of facade fiberglass material is shown in the video below.

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

For correct execution When reinforcing walls with mesh, it is necessary to take into account the type of mortar used, the installation location (outside or inside the building), and the expected height of the coating. Also required to use suitable technology installation Compliance with the listed conditions allows you to plaster walls or ceilings with high quality, minimize the possibility of cracking, and not be afraid of shrinkage of the house.

Anyone who has worked on wall finishing knows that when applying a thick layer of plaster, the material may not be able to withstand its own weight and begin to peel off from the wall surface. To prevent this from happening, a reinforcing mesh is used. It is mounted on the wall and takes on part of the load.

In what cases is a mesh needed?

If the walls are plastered without a mesh, there is a possibility of the material peeling off under the influence of its own weight. Thanks to the reinforcing mesh, it is created monolithic slab, which can withstand any load. For plaster of different thicknesses, different meshes are created, designed for a specific load.

The use of a mesh makes it possible to form a durable layer of mortar, on which cracks will not appear even with prolonged use of the room. This result cannot be achieved without the use of the described products.

It is worth noting that even with improper mixing or non-compliance with the temperature level, the mesh helps maintain the integrity of the plaster. There are special meshes for facades that are not subject to corrosion.

Types of grids

On the market building materials You can find many varieties of meshes on which plaster is applied. In order not to make a mistake when choosing, it is worth considering the main types of such products and their features:


To choose from the proposed options, it is enough to determine in what conditions the mesh 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 to interior walls You can use a plastic mesh.

How to attach the plaster mesh

To understand how to properly attach the mesh to the wall, it is worth considering the two most popular types of mesh - fiberglass and metal. It is much easier to secure the first named type of product, since for this you only need to screw in several screws at an equal distance from each other. Such fastenings are sufficient to securely hold the mesh.

To keep the mesh more securely, you should roll it out across its entire width in one piece, without dividing the product into several. Vertical beacons are installed at a distance of about two meters from each other during installation. After the mesh is hung on the screws, the thrown plaster seals it to the wall, so additional elements no fastenings needed.

Installation process metal mesh somewhat different. This is due to the fact that under its own weight such a product is not able to be securely held on the mounts. Also, the cells of metal mesh are large and require additional fastening mounting tape.

To secure it, you only need to cut off part of the mounting tape so that it can completely cover one cell. After cutting the mounting tape, it is fixed to the wall with self-tapping screws. You need to calculate the distance between the fasteners in such a way that the mesh does not sag on any section of the wall.

Surface preparation

Before you start plastering the walls, you need to clean the surface of dirt and old finishing materials. After finishing works there should not be any on the surface additional materials, as they can cause peeling of the plaster.

After cleaning the surface of the walls, it is necessary to apply a primer. Such compositions increase the strength of the wall and improve the quality of adhesion. They also prevent mold and corrosion. The primer helps the surface dry quickly and promotes better absorption of compounds that are applied after it.

Applying plaster

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

First layer. Plaster is usually applied in two or three layers, depending on the material of the walls. Concrete, for example, requires three coats. The first of them is called “spray”. The plaster at this stage has a creamy consistency and is thrown onto the wall surface in any order. The composition can be spread, but throwing it on allows you to speed up the process. After applying plaster to specific area the walls need to be washed with a tool. After casting, the composition is leveled with a two-handed spatula from bottom to top.

Second layer. After the first layer has completely dried, you need to knead the plaster, the consistency of which should resemble dough. Then you need to throw the composition on the wall and, taking a trowel, spread it in the horizontal and vertical directions. It is after applying the second layer that the reinforcing mesh is completely covered with plaster. If it still protrudes to the surface, you need to apply the plaster again.

Third layer. At this stage, you need to level the composition more carefully so that no errors remain on the surface of the walls. Before applying the finishing layer, you need to wet the surface of the plaster.

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

The final stage of work

After the plaster has completely dried, it must be prepared for fixing finishing materials. To paint and wallpaper, just sand the surface with sandpaper. If there are noticeable unevenness on the wall, you need to start using the largest brand of paper. For ease of work, a piece of product is clamped on a grater. Grinding is done in a circular motion with little effort so as not to create new defects on the surface.

When the wall becomes uniform, you need to change the brand and continue grouting. If the surface will be painted, you need to take P120 paper. During the entire process, you should use goggles and a respirator to protect yourself from dust.

Since it is quite difficult to sand the surface in the corners, it is worth working either without a grater or using bars with sharp corners. If you want to make the work process easier and faster, you can purchase an electric grater. But to treat the walls of one apartment, it is not profitable to buy such a product. After sanding, you need to sweep away the dust with a brush.

Applying plaster under wallpaper and painting

Before starting work, you should determine exactly how the room will look and what will be used as finishing materials. If you choose wallpaper, you need to determine its type and thickness in advance. If they are thin, you need to apply several layers of leveling plaster. This will allow you to hang the wallpaper without any unevenness or bubbles.

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

If plastering the wall surface occurs before painting, you should carefully prepare the wall, without leaving even small irregularities on it. The whole process is carried out in several stages:

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

When finishing ceilings and walls, plaster and mesh under the plaster are often used.

Plaster may not always lie perfectly on the surface. In order for the plaster layer to be fixed more efficiently, you can use a plaster mesh.

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

Scope and characteristics

The mesh under the plaster is used to ensure that the plaster layer holds firmly. The fact is that even with a carefully prepared surface for plaster, the solution can sometimes not lie as it should. This can happen if some mistakes are made when plastering: failure to comply with proportions, temperature and humidity levels in the room...

In order to avoid such mistakes, it is necessary to use plastering meshes, thanks to which the negative consequences of plastering are significantly minimized. These nets are designed to take the load that may occur due to improper use of the room.

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

Before you purchase a mesh for plastering, you need to choose one that is suitable for a specific job.

Types of mesh

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

There are different types of mesh:

  • Masonry mesh. It is made of a polymer substance. The size of each cell in the grid is 5x5 millimeters. Used for brickwork.
  • Universal nets are made of polyurethane. Used for plastering and finishing work. There are different types of universal mesh: small - cell size 6x6, medium - 13x15 and large - 22x35.
  • Fiberglass mesh. Made from fiberglass, which is specially processed. Cell size – 5x5 mm. This mesh is particularly durable and resistant to various temperatures and chemical exposure. Has wide application./li>
  • Plurima. This mesh is made of polypropylene. Cell size – 5x6 mm. Possesses chemical inertness. Used for interior and exterior finishing work.
  • Armaflex. It is made of polypropylene and has reinforced components. Cell size – 12x15. Used when plastering the surface with a thick layer.
  • Syntoflex. Also consists of polypropylene. Cell sizes are 12x14 and 22x35. Suitable for interior and exterior finishing work.
  • Steel mesh. The basis of this mesh is steel rods, which are soldered at the nodes. There is a wide range of cell sizes available.
  • Metal grid. Cell sizes vary. It is used only for finishing work inside the building.
  • Galvanized mesh. It is made of galvanized rods, which are soldered into units. Cell sizes may vary. It is characterized by high strength and durability. Used for external and internal finishing works.

Which one to choose?

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

  • If the required thickness of the plaster layer is up to 20 mm, you can not use the mesh at all.
  • If there are rusts and the required thickness of the plaster layer is from 20 to 30 mm. The most acceptable would be to use fiberglass mesh.
  • With a plaster layer thickness of 30 mm. It is necessary to use a metal mesh.
  • If finishing is necessary uneven ceiling, in which height differences range from 50 mm, it is better to abandon plastering altogether, replacing the plaster with suspended or suspended ceiling. It will be much easier and cheaper this way.

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

Mesh plaster is effective way rough wall finishing. But what is the essence of this method, which grid to choose and in what cases should it be used? Next, we will try to answer these and some other questions related to applying plaster to the mesh.

Why do you need a plaster mesh?

As you know, plaster is universal material, as it can be applied to almost any surface. However, not all of them have sufficient adhesion to plaster mortar, as a result of which the finish may peel and crumble. Moreover, sometimes this process begins almost immediately after the repair is completed.

Such surfaces primarily include brick and wooden walls. Accordingly, the use of plaster mesh will prevent this process. In addition, this material is used for another reason - it helps reduce surface cracking, which is especially important if the finishing is done in a thick layer.

Types of mesh and their application

As of today construction market There are several types of meshes. First of all, they differ in the material from which they are made.

The following types can be used for plaster:

  • Fiberglass;
  • Metal.

If the wall surface is fairly smooth and the plaster will be applied in a thin layer, then a fiberglass reinforcing sheet will be sufficient to strengthen the finish. But if the walls are crooked and the thickness of the plaster is more than two centimeters, then you cannot do without a metal mesh.

Unlike fiberglass, metal mesh comes in different types:

  • Woven;
  • Wicker;
  • Welded;
  • Expanded metal.

Now let's look at the features of each type of material, which will allow us to do right choice when purchasing it.

Woven

This mesh is a fairly flexible fabric made from durable thin wire. It is sold in large rolls, making it quite convenient to transport.

Most often it is also used for interior work. The only thing when choosing this material is to pay attention to the cross-section of the cell. Woven plaster mesh 10x10 mm is the most the best option.

Advice! Required condition use of this canvas, is the presence of a zinc coating on it.

Wicker

This material is also called mesh. As you might guess, it is done by weaving wire.

Most often, the cell cross-section of this plaster mesh is 20x20 mm. Most often it is used to strengthen large areas walls and facades. The material is also sold in rolls, like the previous canvas.

Advice! If plastering is carried out with a clay-based solution, then a 50x50 mm plaster mesh is used for these purposes, i.e. with a large cell cross-section.

Welded

Welded mesh is made by joining wires using the welding method. This fabric has symmetrical square cells.

Most often, the wire for its manufacture is galvanized or treated with a special polymer protective composition. Typically, this material is used for plastering walls subject to severe shrinkage. Thus, welded mesh can be used when plastering new buildings or buildings that stand on moving soils.

Expanded metal

The TsPVS plaster mesh is quite different complex process manufacturing. It is based on a metal sheet, in which holes are made on a special machine. After this, such metal is subjected to tension, as a result of which it turns into a mesh.

The cells have the shape of diamonds and are arranged in a checkerboard pattern. This material is used only in cases where the consumption of plaster mortar per square meter is expected to be insignificant.

TsPVS is also sold in rolls one meter wide and of different lengths. As a rule, the price for expanded metal mesh is the highest.

Technology of applying plaster to mesh

Preparing the base

Despite the use of mesh, the base still needs to be carefully prepared before plastering:

  • First of all, the old coating is removed from the wall - paint, plaster, etc.
  • All peeling and crumbling areas must be removed.
  • Then the base is cleaned of dust. If there are traces of mold or mildew on the surface, the wall must be cleaned with a wire brush.
  • A layer of primer is applied to a solid and clean wall surface, which improves adhesion, strengthens the base and protects the wall from the effects of microorganisms.

Mesh installation

After the base has been prepared and coated with primer, the plaster mesh can be installed.

The work is carried out in the following order:

  • The first step is to measure the height of the wall that will be plastered.
  • Next, you need to unroll the roll and cut the blades required size special metal scissors.
  • After all the pieces are prepared, they should be attached to the wall. Installation of plaster mesh is usually done with self-tapping screws or construction nails. The canvases should be overlapped by 10 cm. To ensure that the mesh is securely fixed, it is necessary to use washers or perforated galvanized tape.

Note! When installing the mesh, you should pay attention so that it does not sag or lag behind the wall by more than 1 cm.

It must be said that in most cases, for internal installations, a plaster mesh of 5 - 5 mm or with cells of 10 by 10 mm is used, with the exception of certain cases, which are indicated above.

Installation of beacons

After the mesh is securely fixed to the wall, you need to install beacons with your own hands, thanks to which you can achieve Smooth surface walls For these purposes, a plaster profile should be used.

Installation is carried out in the following order:

  • First of all, the vertical position of the outer beacon is set using two self-tapping screws. The position of the profile should be controlled using a building level.
  • Then the profile is fixed on self-tapping screws using gypsum mortar, which quickly hardens.
  • After this, the outermost beacon is installed on the other side of the wall. To ensure that the remaining guides are located in the same plane, you can stretch a thread between the outer beacons.
  • Next, intermediate profiles are mounted in increments smaller than the length of the rule, which will allow the tool to rest on them when leveling the wall.

Applying plaster

After installing the beacons, you can proceed directly to plastering.

The instructions look like this:

  • Immediately before finishing, it is necessary to have a creamy consistency.
  • Then the first layer of plaster is applied, which is called spraying. The composition is thrown onto the walls using a trowel or ladle. While doing this work, some force should be applied so that the mixture sticks to the surface and does not slide down.

The spray layer should be about 1 cm.

  • After the spray has set, you should prepare a thicker solution and apply it to the walls using a trowel. If this is achieved required thickness, then the surface must be leveled using the rule. To do this, the tool should be pressed against the beacons and pulled from the bottom up, which will allow the solution to be rubbed in and its excess removed.
  • When the plaster has set, you need to remove the beacons and seal the remaining marks with a solution.
  • The final step is to level the corners. Joints between wall and ceiling, as well as internal corners, leveled using an angle spatula. For finishing external corners metal perforated corners are used.

This completes the plastering process; now the mesh and plaster form a durable coating on the wall that can last for many years.

I must say that we considered the installation of metal mesh. If fiberglass sheeting is used, it is usually glued to the wall directly during the plaster application process.

Conclusion

Having understood the types and types of mesh for plaster, as well as their purpose, it will not be difficult to choose the right material. However, to achieve a positive effect from its use, it is necessary to follow the finishing technology described above.

For more information on this topic, watch the video in this article.

When plastering wall surfaces in any room, specialists use reinforcing mesh under the plaster to prevent peeling of the plaster layer and the appearance of cracks. A special mesh helps strengthen the core finishing material.

Varieties

There are several types of mesh for plaster; They differ in operating parameters and features of use. Today, a number of manufacturers offer a wide range of mesh products.

The following varieties are distinguished:


Prices

How much does mesh for plaster cost? The cost of mesh intended for plastering wall surfaces differs. The price is determined based on the type of product and the material from which it is made, and operational parameters.

Approximate price:

  • woven fiberglass (1x55 m) - from 750 to 8000 rubles, depending on density;
  • based on polypropylene (1x30 m) - from 700 to 1200 rubles;
  • made of steel (1x10 m) - from 50 to 95 rubles;
  • with galvanized coating - from 350 to 580 rubles.

Subtleties of choice

The need to use reinforcing mesh devices arises when plastering bases made of concrete, wood and brick.

Attention! If the mesh is not used, the likelihood of peeling of the facing material increases.

The choice of the type of construction reinforcing mesh depends on the type of work to be performed, the thickness of the finishing layer and the conditions of use.

What mesh is needed for plastering walls and which is better? There are several rules that help you decide: which type of mesh is more suitable and in which situations, and in which cases you can do without using a reinforcing product.

For cladding ceiling surface, monolithic load-bearing structures made of reinforced concrete and plaster density less than 10 mm, it is not necessary to use mesh padding.

It is advisable to install fiberglass mesh with a finishing density of less than 30 mm.

Metal ones should be used with a density of more than 30 mm.

Galvanized - considered the best option for facade works and for internal lining in high humidity conditions.

Reinforcement plastic look It is preferable to use mesh for finishing layers with a maximum thickness of 20 mm, as well as in cases where there is a possibility of subsidence of the base. Ideal for plaster surfaces.

To eliminate shallow cracks and mask joints, you can use duct tape: It will add strength to weakened areas of the base.

To reinforce slopes with a large layer of plaster, steel mesh is used, and with a small layer, a fiberglass product is used. If the slope width exceeds 15 cm and the plaster layer is less than 6 mm, reinforcement is still used.

Plastering wall surfaces using a grid

Plaster mortar allows you to level wall surfaces, but if there is a large number of cracks or other defects, plastering alone is not enough to smooth the base. In such a situation, it is recommended to use wall reinforcement using a special mounting mesh.

Reinforced surfaces become stronger and their ability to withstand mechanical pressure increases.

The technology for plastering wall surfaces includes several stages:

  1. Preparing the base. First of all, the old finishing material is removed from the surface and crumbling areas are leveled. After removing the worn layer, the base is cleaned of dust and dirt; if there is mold, it is scraped off with a steel brush. After this, the cleaned surface is coated with a primer in order to improve the adhesion of the base to the plaster material and protect the wall from the effects of harmful microorganisms.
  2. Installation of reinforcing mesh. The first step is to measure the height of the wall, and then cut the canvas to the required size. Cut the mesh using scissors designed for cutting metal. The cuts are attached to the wall surface by overlapping them by about 10 cm. How to secure the mesh for plaster? It is fastened with self-tapping screws, fixed with washers or galvanized tape.
  3. Installation plaster beacons . To level the surface, it is preferable to use a plaster profile. First, the location of the outer beacon is indicated (vertically); they should be secured with two screws. After this, the outer beacon is mounted with reverse side. To evenly position all the guides, pull the thread between the outer beacons. Then install intermediate beacons at a distance smaller than the length of the rule.
  4. On a note! Use a level to check the position of the beacon.
  5. Plaster coating. Before you start applying the material, prepare a solution with a consistency close to sour cream. The primary layer is applied by spraying using a trowel so that the solution seeps through the mesh and adheres to the wall. It is important that the solution does not flow down the wall. The spray density is about 10 mm. After the primary layer has dried, prepare a thicker substance and apply it to the wall surfaces with a trowel. Level the surface using a rule, pressing it against the beacons and turning from bottom to top to remove excess solution. After the plaster layer has dried, remove the beacons and fill the recesses with mortar.
  6. Aligning corners. The joints between the ceiling surface and the wall are leveled manually with an angled spatula. External corners are leveled using perforated steel corners. This completes the work of plastering the walls.

We considered the option of installing steel plaster mesh. Installation based on durable materials is slightly different.

Installation method for fiberglass mesh:

Preparation for installation of fiberglass reinforcing material is no different from similar work for fastening steel mesh.

Attention! When applying the solution, make sure that it is evenly distributed over the surface of the mesh, smooth it out - from the center of the canvas to the edges. Press the edges at the corners with a rule or an angular spatula.

The method of installing a polymer mesh involves a number of stages.

  1. At the first stage, the base is prepared. Preparatory work include cleaning and priming the surface.
  2. The next step is to measure the wall surfaces and cut the canvas in accordance with the measurements taken and add a margin of approximately 10 cm (for overlapping panels).
  3. After this, the adhesive-based composition is prepared.
  4. The main stage is applying the initial plaster layer with a density of 3-5 mm with pressing the painting mesh into the solution.
  5. After the initial layer has dried, the surface is covered with a primer and the final layer of plaster is applied, leveling is carried out as a rule.
  6. On last stage dried wall surfaces are sanded.

A few useful quick tips will allow you to complete the job of plastering walls with the highest quality possible.

  1. The denser the plaster layer applied to the base of brick or concrete, the stronger the mounted steel mesh should be.
  2. Simple steel mesh in rooms with high level humidity, for example, in baths and bathrooms, as well as for external cladding, it is undesirable to use. The thing is that steel types of material are prone to rust. It is preferable to install a mesh made of fiberglass or welded with a galvanized coating.
  3. Before installing a metal reinforcing product, it must be degreased.
  4. It is unacceptable to use a reinforcing mesh made of plastic for plaster mortar prepared on the basis of cement, because over time cement mixture will corrode the product.
  5. Many people, when performing work on plastering walls, first lay the mesh to the wall surface and only then plaster - professionals do not advise doing this: as a result, cavities may form in the cells and the degree of adhesion will decrease.
  6. When calculating the required number of dowels, keep in mind that per 1 sq. m. approximately 16-20 pcs are required.
  7. When installing reinforcing material, do not allow it to sag or peel off from the surface by more than 10 mm.
  8. For internal cladding, as well as for external cladding, the best option will use a reinforcing mesh with cells with a diameter of 5x5 mm and 10x10 mm.
  9. The fiberglass mesh must be impregnated with a polyacrylic compound. If the mesh is not impregnated, it cannot be used with plaster mortar, otherwise it will gradually collapse under the influence of alkalis.
  10. If shingles were used to decorate the wooden surfaces of the walls, it is preferable to choose a chain-link mesh.
  11. With a layer density of about 50 mm, due to strong surface differences, it is undesirable to plaster the walls. Preferably used for decoration Wall panels- this finishing material will help hide existing defects.
  12. In the case of plastering small areas, it can be used as fasteners. plaster mixture. It is applied pointwise, after which it is evenly distributed over the entire area.

The use of reinforcing plaster mesh in the process of performing internal work on plastering wall surfaces allows this to be done efficiently. The presence of a mesh extends the service life of the finishing material; the main thing is to choose the right type of reinforcing mesh, based on the conditions of its use.
