With all the diversity building materials, used in the construction of walls, the most popular type of finishing is still plaster. Even if later it is planned to use other Decoration Materials, everyone is trying to do at least rough plaster.

In the 90s, the concept of “European-quality renovation” entered our lives. At the same time, everyone puts their own meaning into it. Some people mean high-quality finishing materials and expensive repairs, others believe that these are, first of all, perfectly smooth surfaces made in accordance with European standards. For, use a mesh for plaster.

However, the standards European countries do not necessarily require the use of reinforcing mesh. It is recommended to use it only in difficult places.

The mesh helps reduce the appearance of cracks, but does not ensure the integrity of the finishing layer.

Advantages when using:

1. Applying the solution to the mesh can be done quickly, which makes plastering work easy, even without experience.
2. If the mesh is securely fastened to the base, then you can be confident in the durability and strength of the finishing layer.
3. The plaster applied to the mesh will, in fact, be monolithic design, which will not be subject to shedding and cracking.
4. Grid plaster provides reliable adhesion to walls made of any materials.

What are they?

For various types different types of meshes are used for bases:

Masonry

This mesh is made from polymers. The cells in the grid have dimensions of 5*5 mm. It is used for plastering.

It is used not only for plastering works ah, but also finishing works ah with the help. It is made from polyurethane. Several types are available: cell size 6*6 mm is considered small, 13*15 mm is medium and 22*35 is large.

Made from specially treated fiberglass. It is used for both plastering and finishing work. Cell dimensions 5*5 mm. This is the most resistant mesh to chemical influences. In addition, fiberglass tolerates elevated temperatures well.

This type is made of polypropylene. Resistant to aggressive environments. Has a cell size of 5*6 mm. Can be used for plastering internal and external surfaces;

Armaflex

The mesh is made of polypropylene, but additionally has reinforced cell corners. Cell dimensions 12*15 mm. It is used when plastering surfaces with a thick layer.

It consists of steel rods soldered at the corners of the cells. Available whole line steel mesh with different cell sizes.

Due to its susceptibility to corrosion, it is only suitable for interior work. Just like steel ones, they have various sizes cells.

Galvanized

Unlike metal, it can be used for outdoor work.

Which one to choose?

In order to select the correct mesh, you need to use a level to determine the differences in the base. This will allow you to know approximately how thick the plaster layer will be.

There are several solutions for using a grid:

1. If the expected plaster layer is less than 20 mm, it is recommended to use a universal mesh. It will do an excellent job of fixing the mortar and preventing the appearance of cracks.
2. If the plaster layer is more than 3 mm, a metal mesh is required.
3. If the differences are more than 50 m, you should think about it.

How to install?

The installation technology depends on the material from which it is made.

To attach the metal mesh you will need self-tapping screws, dowels, metal scissors and galvanized mounting tape.

All work should be performed in accordance with the instructions:

1. Using metal scissors, cut a piece of mesh to fit the wall and degrease it. To do this, you can use any solvent or acetone.
2. Using metal scissors, cut the galvanized mounting tape into small pieces.
3. The mesh must be installed from top to bottom, placing the canvas horizontally, starting from the ceiling itself. The upper edge of the first row is secured with self-tapping screws. Considering that the metal mesh has large enough cell sizes so that the mesh does not jump off the screws, pieces of mounting tape are placed under their caps so that it presses one side of the cell to the wall. There are widened nuts on sale that can also be used for these purposes, however, they are much more expensive than mounting tape.
4. If the mesh is installed on concrete or brick wall, then the fastening must be carried out using pre-installed dowels. To do this, you can use ordinary plastic parts, which are quite inexpensive.
5. Fastening must be done often enough in a checkerboard pattern so that the mesh fits tightly to the wall. The ideal distance between dowels is 500 mm.
6. The mesh panels are attached over the entire surface of the wall with an overlap of 80-100 mm.
7. Fastening fiberglass plaster mesh.

This mesh does not need to be attached over the entire surface: it is enough to securely attach it along the upper edge. It is also attached starting from the ceiling. The cell sizes of such a mesh are small, and it itself has little weight, which makes it permissible to use only self-tapping screws, without additional accessories such as mounting tape or nuts.

It is important that there is a piece of mesh left in the corners to create a slight overlap.

The greatest strength can be achieved if the mesh is applied to the wall as a whole panel. Therefore, beacons must be placed along a grid already attached to the wall.

Ceiling mesh reinforcement

Several materials can be used to reinforce ceilings.

Just like for walls, they use a mesh made of fiberglass, metal, as well as shingles - a structure made of wooden slats:

1. Plastic or fiberglass mesh It is recommended to use if the expected putty layer is no more than 30 mm.
2. For height differences of more than 30 mm, it is better to use a metal mesh. It is much more expensive than plastic, but much stronger.
3. Shingles have been used for many years. For its construction, a 20*8 mm rail is used, which is attached to each other in the form of slats. This is the simplest method of reinforcing the plaster layer, but is only suitable for wooden bases, simple design.

Before attaching the mesh, it is necessary to prepare a mounting tape, pre-cut into small pieces with metal scissors. The metal mesh should first be degreased using acetone or other solvents. As a last resort, you can simply wash it with any soap and detergent that can wash away oil or grease traces.

The mesh needs to be cut to the size of the ceiling. It is important to remember that one canvas should overlap the previous one by at least 12-15 cm.

Fastening:

1. The shingles are attached very simply: you just need to nail the structure at the tops of the cells to the ceiling.
2. Fastening metal or plastic mesh can be produced both on nails and on dowel-nails. They need to be arranged in a checkerboard pattern at a distance of 200-300 mm from each other.
3. If you do not use a mounting grid, you can use nails with large heads or use washers.

The use of plaster mesh when sealing joints in floor slabs

To carry out these works, a strip is cut out of the mesh along the width of the area, adding 5-10 cm on each side. It is attached in the usual way and sealed with mortar.

In any case, the application of the solution should be started from the middle of the room, moving evenly towards the walls.

Price

1. Metal mesh – 140 rubles per square meter.
2. Plastic - 30-40 rubles per square meter.
3. Fiberglass mesh - 50-60 rubles per square meter.

The use of reinforcing mesh allows you to make repairs more durable and of higher quality. Subsequently, it will be enough to carry out only redecorating: replacing wallpaper, painting the ceiling.

When facade plaster on a grid is used for finishing, the technology of the procedure must be followed to the smallest detail. From how well they are made facing works, are completely dependent and appearance structure, and its protection from adverse weather influences. The less the walls of a building are exposed to adverse external influences, the longer its service life will be.

Why reinforce plaster?

Due to its availability and low price, plaster is a fairly popular material for finishing buildings. But we must take into account that it is not applied equally conveniently to all surfaces. Facades made of wood, concrete and brick should be plastered using a special mesh.

The addition of this material provides the layers with high-quality adhesion and helps the finish last longer.

Facade plaster mesh significantly increases the strength of the prepared plaster mortar, which is especially valuable when working with large areas and transitioning from one material to another. Plastering the facade using mesh allows you to improve the effectiveness of work during the construction and finishing of new buildings, whose walls have been settling for some time.

Plaster layers can be reinforced using polymer, metal, fiberglass and other types of material. Its selection is determined by the characteristics of the application.

What are the types of reinforcing mesh?

The finishing layer of plaster, after being applied to the surface of walls made of brick, concrete or wood, often cracks and can peel off from the base. Reinforcing surfaces using a special mesh helps avoid this problem. Auxiliary materials for finishing they differ according to the type of raw materials used for manufacturing:

1. Woven mesh is a flexible and very durable material with a small thickness. It is made from wire of a certain cross-section, which is woven into a single fabric. The woven facade mesh for plaster is equipped with a zinc coating and has square cells of 1x1 cm. The material is produced in rolls.
2. The chain-link mesh has a larger cell size than the previous version. It is used in cases where the coverage area is very large. It is only suitable for processing an absolutely clean facade that does not have a relief coating, so surface preparation should be carried out with special care.
3. U welded variety the cells are square in shape. The material is made using spot welding at the intersection of wire rods. They are distributed perpendicular to each other, then the connection is made. The material used to make the mesh is low-carbon wire, light-colored, coated with a layer of polymers or galvanized. To prevent cracking of the finishing layer due to the active shrinkage process, welded mesh will suit best way. It is most convenient to use material with cells of 2–3 cm.
4. The expanded metal mesh for the facade is made from metal sheets using special pressing equipment. Its cells are obtained in the shape of rhombuses; their arrangement is staggered. It applies if per 1 sq. m area, a small amount of plaster is planned. The material is produced in rolls, the width of which is 1 m.

If the layer of plaster is very thin, then use a material made of polymers or fiberglass.

How to perform plastering work on a façade using metal mesh

When starting the finishing work, it is necessary to take into account that the facade metal mesh under the plaster is laid under a layer of finishing mortar with a thickness of at least 3 cm. The work process consists of the following stages:

1. All surfaces that require mesh plastering are primed.
2. The height of the facade from the roof to the ground is measured. Then, based on these values, pieces of material are cut.
3. The mesh for plastering the facade is located on the surface of the wall; the pieces overlap. For fastening you will need screws and a screwdriver.
4. After measures have been taken to strengthen façade mesh, you can begin preparing the finishing solution. An antiseptic drug is added to it.
5. Plastering the surface of the building must begin from the bottom. Apply the solution using a spatula; To level the layer, use a rule or a spatula of a suitable size.
6. When the first layer has dried, the next one is applied. It should be more subtle. After applying it to the wall, the mortar is leveled using a spatula.
7. The finishing of the facade is considered complete when the reinforcement is completely hidden under a layer of mortar.

If, after completion of the work, unevenness is noticeable on the surface, or the color of the dried solution seems too dull, then additional finishing can be done. Irregularities are puttied, cleaned, and then painted.

Plastering the facade using a polymer mesh

Polymer reinforcement has a very valuable quality: it successfully resists deformation of the plaster layer.

Thanks to your chemical properties it cannot react with oxygen, so rust does not form.

The plastering work procedure is similar to the previous version. But there are also some features:

1. Fastening is often carried out by pressing staples or nails into the plaster layer. Can be used for fixation construction stapler, if the wall material allows.
2. The plastering process should begin not from the bottom, but from the middle of the polymer mesh. Then the plaster layer is distributed in each direction, gradually approaching the edges. The movements are performed in the same way as when gluing wallpaper, when the air is expelled from under it.
3. It is necessary to carefully ensure that the mesh does not stretch during the finishing work. Polymer material It is elastic, so when working you need to carefully monitor it so that it does not form bubbles.

Plastering facades using insulating materials

When using wall insulation when cladding a facade, the same technologies are used that are used when applying the solution to an unobstructed surface. The mesh used is hidden with a layer of plaster and, if necessary, after drying, receives additional processing. The operating procedure is as follows:

1. A layer of foam plastic or mineral wool is attached to the façade using special glue or dowels.
2. A mesh is laid on top of the insulation and fixed with self-tapping screws or plastic fasteners.
3. Installed plaster beacons- they help control the smoothness of the finish.
4. The plaster layer is applied so that it does not reach the ridges of the beacons a few millimeters; then leveled.
5. The next layer is applied after the first has dried and is thinner. It is leveled using the rule, and you should rely on the beacons.

When plastering on a grid, you must carefully select each of the materials - the layers must interact well. It will be necessary to compare the indicators of their vapor permeability and hygroscopicity, thermal conductivity, and frost resistance. Careful attention to materials will ensure long term service to the finishing layer and will help maintain the performance properties of the insulation.

How to finish the plaster layer

The most common method of execution finishing coating for external and interior walls After plastering it can be called painting. Before performing this stage of work, it is necessary to conduct a rigorous assessment of the condition of the coating. Check the quality of the base and repair cracks if necessary. Try to determine how strong the connection of the plaster layer with the surface of the building is. Plaster particles should not fall off, and the layer should be uniform.

Putty the walls. After the putty layer has hardened, sand the surface using sandpaper. Before applying the coloring agent, additionally treat with a primer on the water based. Choose your coloring composition carefully.

A fresh finishing layer usually contains a large amount of alkali. Therefore, you should not choose solvent-based formulations. When working with soluble organic compounds Be sure to protect the surface with a synthetic primer.

The most convenient tool for painting is to use a roller.

Work the surface carefully, not skipping any areas. You can apply the 2nd coat of paint only after 1 has completely dried. To paint a plastered facade, it is better to use acrylic paints; Alkyd and latex are suitable.

When plastering using facade mesh, good adhesion of materials is ensured.

The finishing layer is visually attractive due to the use of polymers and increased service life of the material.

In order for the work carried out to give the maximum effect, it is necessary not only to decide which mesh to choose for a particular surface, but also to carefully consider the properties of each of the materials used for finishing.

Plaster is one of the most popular materials for finishing walls and ceilings today. Not so long ago, shingles for plaster were widely used to strengthen the surface of walls and ceilings. Today it is increasingly being replaced by reinforcing mesh for plaster. In order for the plaster layer to last as long as possible, it must be properly reinforced with a special plaster mesh. The mesh for plaster can be metal or polyurethane and is attached to the surface using glue, self-tapping screws, screws or other devices for the same purpose. As a rule, it is sold in rolls and can have different sizes.

The following types of plaster mesh exist:

• masonry mesh – plastic, made of a polymer substance, has a cell size of 5x5 mm, used for brickwork;
• universal mesh (small)– made of polyurethane, cell size 6x6 mm, well suited for reinforcing both finishing and plaster mixtures. It has wide functionality, allows you to carry out plastering work on any area;
• mesh station wagon (medium)– has the same structure as the small station wagon, cell size 13x15 mm;
• universal mesh (large)– differs in cell size - 22x35 mm, used for reinforcing large areas, such as warehouses, workshop facades and other large structures;
• fiberglass mesh - its fibers consist of glass fiber processed in a special way, and has a cell size of 5x5. Resistant to temperature and chemical influences, heavy-duty, can withstand heavy loads. This base is widely used for reinforcement and has almost no restrictions.
• Plurim mesh is a 2-axis oriented plaster mesh, made of polypropylene, with a cell size of 5x6 mm. It is characterized by chemical inertness and lightness and can be used for both external and internal work.
• armaflex - polypropylene mesh, with reinforced nodes, has a cell size of 12x15 mm. It is extremely durable and suitable for use in areas with increased load on the plaster layer;
• syntoflex mesh– made of polypropylene, has cell sizes of 12x14 and 22x35 mm. Lightweight, inert to chemical exposure. Can be used for interior and exterior decoration.
• steel mesh - is based on steel rods that are soldered in nodes, as well as a wide range of cells. It can withstand loads very well, but can only be used for interior finishing, since steel is not able to withstand precipitation.
• galvanized mesh– is a network intertwined from galvanized rods, soldered in knots, has a wide variety of cell sizes. It is durable, suitable for both external and internal work, and can be used in any conditions.

Depending on how you apply the plaster (coat or spray), metal or plastic mesh for plaster can be secured in different ways. The bottom plaster layer is reinforced with the selected mesh over the applied mortar required thickness, pressing it slightly.

The ideal option for applying the final - decorative or covering layer - would be to first attach the reinforcement to a dry surface using special devices. If the surface to be treated is small, the fastener itself can be used directly. plaster mortar. In these cases, it should be applied pointwise, only to secure the mesh. After that required thickness The plaster layer is spread evenly over the entire surface.

Which plaster mesh is best to use?

When choosing a plaster mesh, the thickness of the plaster along the mesh always comes to the fore. It is necessary to calculate the lowest point on the ceiling using a laser or building level, then mark it and estimate the maximum thickness of the future plaster layer.

Depending on the result obtained, you should choose one of the options:

1. If the thickness of the plaster layer does not exceed 20 mm, in the absence of rust on the base of the ceiling, you can apply plaster without a mesh. Let's move on to installing beacons.
2. If there are rusts on the ceiling, or the future plaster layer will be from 20 to 30 mm, it is advisable to use a fiberglass plaster mesh. The main purpose of such meshes is to protect the surface from cracks.
3. If the layer thickness is over 30 mm, you cannot do without a metal reinforcing mesh. A metal mesh underneath the plaster will prevent it from peeling off from the base under its own weight.
4. At uneven ceiling, when differences in height can be more than 50 mm, it is better to completely abandon plaster. In this case, it is easier to use a suspended or suspended ceiling.

A detailed description of the stage of installing beacons in the article: Plastering walls on beacons

Installation of fiberglass plaster mesh

When buying a mesh, remember that its cells must exceed 5x5 mm, and its density must be from 110 to 160 g/m2. In addition, the material must be alkali-resistant. The minimum thickness of the plaster layer when using fiberglass mesh is 3 mm, the maximum is 30 mm.

Before starting work, the mesh is cut to size into sheets. The size of the canvases will depend on how you are going to place the mesh - across or lengthwise. If there are rustications on the ceiling, the mesh should be placed in one piece along each of the seams. If there are no rustications, then there is no particular difference in the location of the mesh; you just need to make sure that the entire surface is covered with the mesh. It is better to cut with a margin of 10-15 cm to strengthen the seams between the walls and ceiling.

Technique for applying fiberglass mesh

First, the first layer of putty or plaster is applied to the entire surface. A plaster mesh is placed on top of it and then recessed, after which a second layer can be applied. It is permissible to perform this operation in one pass, or wait for the first layer to dry in between. The fiberglass mesh should therefore be placed in the middle of the plaster layer.

Builders most often use screws and brackets to attach the fiberglass mesh to the base, and then plaster directly over it. This method will be justified for a thin layer of plaster (putty). In this case, the mesh will actually be located in the middle of the plaster mortar. However, if the thickness of the plaster mortar is 10 mm or more, the mesh will definitely end up on the edge, reinforcing not the plaster itself, but the surface.

It would be optimal to use the following order of installation of the plaster mesh:

1. Markings should be applied under the beacons, holes should be drilled, and then dowels should be inserted.
2. Installation and leveling of screw heads along each line of plaster beacons.
3. Applying the first layer of plaster along the width of the mesh.
4. A mesh is laid through the screw heads onto the fresh plaster. Next to it is an adjacent layer of plaster, a mesh on top of it, and so on all the way to the wall. It is necessary to place adjacent canvases overlapping each other by at least 10 mm.
5. Then the metal beacons are put on, and the plaster is applied over them as usual.

When mentioning the fiberglass mesh for plaster, it is worth noting that the solution should be applied evenly over the entire surface of the canvas, and smoothing should begin from the middle of the plaster mesh in opposite directions. The ends of the canvases in the corners must be pressed using a rule or a wide spatula. Using the second spatula, the mesh is smoothed down along the wall.

Sequence of actions when installing metal reinforced mesh

Metal reinforced plaster mesh is used if it is necessary to apply a plaster layer of 30 mm or more. It is advisable to opt for galvanized metal mesh, having cells 10x10 or 12x12 mm. Also suitable is galvanized expanded metal mesh, with cells 10x25 mm. The mesh is very light in weight, with a minimum thickness of the plaster layer, it easily adapts to the surface, cuts well and will not leave traces of rust.

Before you start working with metal mesh, you first need to degrease it. Galvanized mesh can simply be washed with water or wiped with a damp cloth.

Stages of work:

1. Cut the mesh into sheets using metal scissors. The dimensions of each canvas will depend on how you are going to place the plaster mesh - along the ceiling, or across it. If there are rustications on the ceiling, the mesh is placed in one piece along each seam.
2. Using a hammer drill, drill 6 mm holes with a drill bit. The depth of the holes should be 2-3 mm greater than the length of the dowel. The hole spacing is 25-30 cm. So, with a step size of 25 cm per 1 square meter You will need to make approximately 16 holes for the dowels.
3. Insert dowels into the holes, then use mounting tape and screws to secure the plaster mesh to the ceiling surface. Its edges must be securely fastened. We overlap adjacent canvases approximately 10 cm over each other. If the mesh lags behind the ceiling in some places, you will need to drill additional holes for fastening.
4. Install metal plaster beacons on the reinforced and tensioned plaster mesh.

When applying plaster on beacons with a layer of 30 mm or more, it may be necessary to plaster in 2 layers with intermediate drying of the first. The first layer of plaster is thrown over the metal mesh using a trowel, pressing the plaster solution so that it passes through the mesh and catches on the surface of the ceiling. Then the solution is spread evenly using a spatula or grater. The second plaster layer can be applied only after the first layer has completely dried.

When using galvanized expanded metal mesh minimum thickness layer will depend on the thickness of this mesh. For example, with a thickness of 0.5-1 mm, a layer of plaster of 5 mm is quite sufficient.

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 surfaces have a 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. The market offers products from large quantity 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.

View	Cell size, mm	Characteristic
masonry (painting)	5*5	plastic sheet used when working outside and inside buildings using gypsum mixtures
universal: small, medium, large	6*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 mesh	5*5	durable, resistant to moisture, cold and heat, chemical compounds
Plurima	5*6	made from polypropylene, chemically inert, used for external and internal 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;
• kind plaster mixture which one 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 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;
• When carrying out plastering work on finishing the external walls of a house, a 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 a 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:

• clean from the 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.

The popularity of plaster coatings is due to several reasons. This material is easy to apply to any surface, it is resistant to mechanical stress, withstands temperature changes well, is durable and economical.

Types of plaster solutions

For various types plastered surfaces are used various compositions plaster. Lime or cement-lime mortar is used for finishing brick walls, and cement mortar is used for concrete surfaces. Such solutions include certain additives and fillers required by the operating conditions and purpose of the surfaces to be plastered. Without them, the solution will turn out to be fragile and surfaces treated with a low-quality solution will quickly become covered with cracks.

Installation of plaster mesh

Metal mesh should cover concrete walls that have strong unevenness and protruding places, areas where they meet wooden and metal surfaces, as well as surfaces that require large thickness plaster marking.

The use of plaster mesh provides the structural rigidity necessary in these cases. This mesh is made from round wire rod or woven from wire.

If the surfaces are significantly uneven, in order for the walls to be plastered on the grid to be of high quality, a frame is installed. On wooden walls slats are nailed to which the mesh is attached with nails or staples. On brick and concrete walls steel pins are mounted to which the mesh is attached with wire. The joints of the walls and the protruding corners of the partitions are sheathed with mesh strips.

On large structures, beams, tees, channels, etc. are used to construct the frame.

The frame is necessary for high-quality fastening and tensioning the mesh. It is stretched evenly and tightly, the joints of the mesh are firmly woven with wire. This is done to ensure that the entire structure is rigid and motionless.

Plastering walls on a grid without a frame

For small ones smooth surfaces It is permissible to plaster walls on a grid without a frame, which is much simpler and cheaper. The mesh is attached to beams and protruding structures using knitting wire with tension and fastening with dowels. To flat surfaces - using a mortar or a construction gun.

The mesh should have small cells and not sag after installation. To protect against corrosion, mesh and metal fasteners, if they do not have protective coating, must be processed oil paint, bitumen varnish or cement laitance.

The main rule when plastering on a mesh is to surround the mesh with the mixture thrown on all sides. If this condition is met and used quality plaster the result is a strong monolithic reinforced mortar slab.
