Plastering on a metal mesh. Overview and tips for choosing reinforcement meshes for wall plastering

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

Appointment

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.

Plastering grid allows high-quality plastering of walls, even for those craftsmen who are doing such work for the first time. At the same time, the highest rates of mortar setting are achieved as a result of reliable laying of the cladding on the textured surface of the mesh.

Areas of use

Currently, plaster mesh is actively used:

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

Material selection

The main criterion for selecting a plaster mesh is the required thickness of the facing layer. Based on this, you should stop at one of these options:

In cases where the plaster layer has a thickness of up to 20 mm, it is quite possible to reliably veneer surfaces without using a plaster mesh.
If the facing layer in the form of plaster is of the order of 20-30 mm, then it is advisable to fix the plaster stack made of fiberglass. The main purpose of such products is to create a protective layer that protects surfaces from cracking.
Plastering 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.
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 plastering.

Installation of metal reinforcing mesh

A metal plaster stack is the most common option when you need to create the most reliable reinforcing surface. To lay such a mesh, 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 the rolls according to the required dimensions. Next, the mesh is degreased with acetone or solvent.

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

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

Laying fiberglass reinforcement mesh

The process of installing fiberglass plaster mesh is an order of magnitude easier compared to fixing a metal reinforcing base. To securely attach 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 fiberglass plastering mesh, additional fixation is not required. When laying the plaster layer, the reinforcing material is fixed with a layer of cladding.

It should be noted that it is most convenient to unwind rolls of material and fix the canvases parallel to the floor plane along the wall. It is better to start the installation of fiberglass plastering mesh 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 sheets.

As practice shows, the highest strength of the reinforcing coating is achieved when the mesh is laid 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 separate pieces.

Renovation is a complex set of works that help to make something beautiful, stylish and comfortable out of an ordinary room. To achieve the most better results it is important to use the right materials and choose those that are best suited for a particular type of work. The use of plaster mesh is becoming more and more frequent, therefore you need to know all its advantages and disadvantages.

Peculiarities

Modern renovation is not complete without the use of plaster, because the finished walls, floor and ceiling must be completely flat, be heat and sound insulated, serve for a long time and reliably. If a layer of plaster is not applied to the rough wall, then the desired effect will not be obtained. In order for the plaster layer to hold securely, not to crack or fall off, it is important to strengthen it. The mesh is just such a fastening mechanism.

If earlier more primitive and inconvenient materials were used to strengthen the surface for plastering, then with the advent of a mesh of new materials, it became much more convenient and faster to work. Plaster mesh can be made of different materials, have different cell size, shape, and the weight of the canvas. All this leads to a different result from its use.

If it is necessary to veneer outer wall, then often a reinforced mesh with large cells is taken, in some cases a chain-link is used.

Almost every hardware store now has a choice of plaster nets, which have different lengths, which makes it possible to choose the optimal amount necessary material for work. The principle of working with it is quite simple, which makes its use more popular for the repair of all premises in a house, apartment, office, obtaining excellent final results.

Plaster mesh is a very important element for carrying out renovation works, because with its use, the finishing of the walls lays down easier, and the result lasts much longer. After plastering using a mesh, the wall will not change its properties, and therefore the wallpaper will not be threatened by breaks in the joints or along the canvas itself. Painted walls are most susceptible to translucent imperfections that appear on them, therefore, having chosen this method, it is important to take care of the reliability of the wall and its strength.

Any type of cladding will be much more confidently attached to a surface that is properly processed, and its service life will increase several times if the surface has been reinforced and protected from various influences and unpleasant environmental factors.

Views

Due to the great popularity of the material, it was necessary to create a certain number of options that would make it possible to carry out puttying on different surfaces as conveniently and efficiently as possible. So, there are such types of mesh as:

Masonry mesh- This is a construction variety that is best placed on brickwork. The material of manufacture is polymer, and the cell size is 5 by 5 mm.
Universal- a small cell is used to reinforce the finishing and plaster mix. It is convenient to use it on any area due to the optimal cell size, which is 6 by 6 mm.
Average universal. The material of manufacture is polyurethane, as in the previous case, but the size is different - by 13 by 15 mm.

Large universal- the cells have dimensions of 22 by 35 mm and with its help you can easily reinforce a large area. It is convenient to make repairs in buildings with large dimensions.
Fiberglass mesh. Its composition is fiberglass, which is processed in a special way. The size of the cells is not large and is 5 by 5 mm. This option easily tolerates temperature differences, exposure chemical elements, while it has high strength and can withstand a large weight of plaster. This option is most often used in work, because it is lightweight, convenient and has no particular contraindications for use.
Plurima- polypropylene biaxially oriented mesh with a mesh of 5 by 6 mm. This option is also convenient to use, because it is not exposed to chemical attack, is lightweight and is used both indoors and outdoors.

Armaflex- polypropylene type of mesh, in which reinforced nodes are provided. The cell in this case is quite long and is 12 by 15 mm. The mesh has high strength, therefore it is most often used where the layer of putty is very large.
Syntoflex- polypropylene version with a cell of 12 by 14, 22 or 35 mm. The lightness of the material and the absence of reaction to chemicals make it possible to work with the mesh both indoors and outdoors.

Steel version Are welded steel rods. The size of the cells can be very different. Is used for interior decoration, because under the influence of precipitation, steel will not serve for a long time and will begin to rust.
Galvanized version involves the interlacing of galvanized rods with each other, which is then soldered. It is a durable material that can be used for leveling the surface in any conditions, both indoors and outdoors.

Reinforcing wall decoration suggested the use of metal meshes, which have certain options for the construction device - these are welded, weaving and expanded metal varieties. The cells can be of different sizes, which is due to a specific task, for which rods with different thicknesses and types of their connection can be used. The resulting mesh has high strength and physical and mechanical characteristics. Wire mesh is used indoors because it does not tolerate increased level moisture and metal corrosion can begin under its influence.

Galvanized variety it has been used for external work for a long time and very successfully, allowing reinforcement to be carried out quickly and efficiently. The size of the cells can be very diverse, and the type of their attachment is welding.

Reinforcement mesh(also called a chain-link) is used if the leveling layer is very thick and complex. When working with a cement wall, you can use any solution, because there are no special selection criteria for such a material, which speaks of its versatility. Often brick, concrete, stone walls are finished with a chain-link, but it can also be used for aerated concrete and wooden surfaces.

Metal grid Expanded-expanded type can be made in any way. Due to the lack of welding spots, the resulting product is durable.

Use a grid for plastering the inner surface of the walls, where the layer of material is no more than 30 mm.

Steel mesh has its advantages, but progress does not stand still and has come to replace it new material... Plastic mesh refers to modern types, it is used on aerated concrete and brick walls... In this case, it is advisable to choose a small cell, because a large one is more suitable for working on facades and a plinth. This material has no problems with a large temperature range, it can even be used to equip an insulating layer.
Glass cloth variation consists of glass, in which there are no alkali impurities, but aluminum is added, which helps to significantly increase the strength of the resulting surface. Chemical influences are not terrible for this material, decay processes are also bypassed, therefore this type is used most often and is considered the main one in work.

The polyurethane variety is also universal.... It is very convenient to use it indoors big size... But the biaxially oriented polymer mesh is the newest material of all existing in this industry. Due to its elasticity and the absence of contraindications for use, it is a universal means for communications that conduct current when working on various facades.

Polypropylene mesh is very strong and can support a lot of weight on itself, therefore it is recommended to use it to strengthen bridges and roads.

In addition, there is also serpyanka, with which it is very convenient to repair cracks in the walls. Due to its fiberglass composition and the ability to self-stick to the surface, this material is now indispensable for wall repair and puttying.

The plastering grid is a very convenient invention that made the repair process easier and significantly improved its results. Variety of grids with different cell sizes help to choose the right one for a certain type of wall.

Thanks to the ability to choose between metal and synthetic options, it is now possible to use the mesh both indoors and outdoors, which significantly improves the result of repairs and extends the life of an object.

Which one to choose?

If we consider the metal type of meshes, then there are criteria by which you need to make a choice in the direction of one or another option. These include:

Qualitative characteristics of raw materials that are taken for the manufacture of a rod or wire. It is advisable to have information on the grade of the steel alloy from which the mesh is made, which will show how high-quality the product is.
The cost of the stack will be higher for small traders, therefore, for large quantities, you should contact the enterprises that are engaged in this. High turnovers of products make it possible to recoup them, which means not to set too high prices.
The quality of the rods themselves, the presence of a galvanized coating. Non-galvanized mesh can be used for internal work, but if it is used for external work and not covered with a special compound, then soon it will rust and traces of corrosion can reach the outer layer of the finish.
You need to choose the right type of mesh. If it is welded, it will be better to hold the plaster on itself than twisted. This is important when work is done with brick wall or from aerated concrete outside the house, where the layer of plaster can reach a significant size.
The rods should have a clearly normalized thickness of the rods, therefore, when choosing a mesh, you must pay attention to the GOST standards in each package.

The plastic version of the plaster mesh is not inferior to any of the above options, it can be used on any surfaces, inside or outside, for the plinth and facade. The only case when it is worth turning to a metal mesh nevertheless is the presence of a thick layer of plaster, which is of considerable weight, in all other situations modern mesh will be much more convenient to work with.

The use of the plastic option also implies the choice of the desired cell size, which is often reduced to 6 by 6 mm, but you can choose another option depending on your wishes and convenience in work.

Dimensions (edit)

Since there are a lot of options for grids for applying plaster, there are a certain number of mesh sizes for each of them. Despite the large selection, there are standards that are best suited for each type and determine the size of the cell. Here they are:

For masonry mesh the most convenient cell size is 5 by 5 mm. The main production material is polymers.
For generic type there are several options - from a small cell 6 by 6 and a medium 13 by 15 to a large 22 by 35 mm. The material for the production is polyurethane. It is used for interior decoration.
For glass mesh the optimal cell size will be 5 by 5 mm, and it is produced from fiberglass fabric.
Plurima it is characterized by the same cell size, but it is made of polypropylene and can be used for a wide variety of types of work.
For metal mesh there are no clear cell sizes, it is selected for a specific type of activity, but due to its composition, it can only be used indoors.
For galvanized mesh the optimal cell sizes are 10x10 and 20x20, but larger dimensions can be found if necessary. This mesh is made from rods that are connected by soldering, which ensures a long service life and reliability of the finished surface.
Armaflex most often it is made with cells of 12 by 15 mm and is used in cases when a thick layer of mortar is used in the work.

Syntoflex a fairly large range of cells that can be used in work is 10 by 10, 12 by 14, 20 by 20, 22 by 35. It is made of polypropylene.
For steel mesh the size of the cells can be different, but the most popular is 20x20 mm. It is made from rods made of metal, which are soldered together. For fixing on the surface, the presence of a corner is required.
For plastic mesh there are no specific norms for the size of the cell. It is most often used for attaching polystyrene and set on glue, after which it is treated with a finishing putty. After that, the process can be considered complete.

It is important to choose the right mesh for repair and pay attention to the GOST indicated on the package. It is this material that will make it possible to make a good repair and guarantee the durability of the coating, otherwise you can expect any result from repair work on plastering the mesh inside and outside the room.

Mounting

Since there are many varieties of plaster mesh, there are also several ways of fixing it. The most popular of these are:

applying a mixture for plaster;
use of self-tapping screws;
the use of dowel-nails;
fixing with screws.

If the first layer of plaster is applied, then the mesh is simply pressed into it. By doing this, you can effectively level the wall and get a strong coating. But for decoration, you need to fasten the selected canvas with fasteners. If such a zone is small, then it can be applied to certain areas. A small layer of solution is enough for a paint net.

If we talk about fiberglass, then to use it, you need the correct sequence of actions:

marking for mounting beacons;
making holes for dowels;
screws are screwed in to a certain depth so that the caps are on the same level;
applying the solution to the desired area;
on top of the plaster, you need to immediately fix the mesh by threading the caps of the screws;
overlay mixture for a new site;
fasten the next piece of mesh with an overlap of about 10 centimeters;
it is necessary to gradually cover the entire room with a solution and apply a mesh on it;
after that, beacons are installed;
the subsequent work is carried out precisely on the lighthouses in order to get a flat surface.

The process of smoothing the mixture along the mesh goes from the middle to its edges. If the thickness of the putty is small, then you can use staples to fix the mesh, and then apply a new layer of putty on top.

If we are talking about a metal mesh, then the sequence of work is different:

cleaning from grease, rinsing the surface and wiping with a damp cloth;
division into pieces of the desired mesh size using metal scissors;
preparation of holes for dowels at a distance of 30 cm from each other;
in the dowels with screws and mounting tape, you need to fix the mesh on the wall surface;
a new section of the mesh is laid with an overlap of 10 cm;
after that, the installation of lighthouses and work on them takes place.

The mesh installation technology is suitable not only for walls, but also for the ceiling. The main thing is to mix the solution correctly, because for ceiling work, the mixture is not needed too liquid, otherwise it will not stick to the surface.

The use of a reinforcing mesh for the ceiling has its own characteristics. It is applied in cases where many small cracks appear on the surface, which cannot be removed in the usual way. In order to carry out work on the installation of a reinforcing mesh on the ceiling, you must:

remove all lagging areas from the surface;
carry out a primer with a penetrating mixture;
dilute PVA glue to liquid state and apply it with a roller to the cracks;
immediately apply a piece of fiberglass to the place smeared with glue and apply PVA again on top;
each new layer of glass fiber must have an overlap of at least 5 centimeters.

The work is carried out until the entire ceiling is pasted over, after which you need to wait until the surface is completely dry and start finishing using any convenient method. Following the above rules, you can easily and correctly make repairs to any room.

The choice of mesh depends primarily on the thickness of the plaster layer. If it is less than 3 cm, then it is recommended to use the fiberglass version, which is placed on the mortar. It dries very quickly, which helps to strengthen the wall and work fully with it.

If the layer of plaster is more than 3 cm, then it is better to use a metal mesh that can easily cope with this weight and help to strengthen the wall surface. Usually this type is used for outdoor decoration.

If work is carried out in a bathroom or pool room, then it is important to choose a reinforced material for work, otherwise the moisture will cover the mesh with rust, which will appear on the surface of the wall, spoil it appearance and break the fortress.

If you need to do plaster finish, then the best option for this there will be a plastic grill. During finishing it is important to use a stack with a minimum cell diameter. In the event that it is necessary to get rid of a crack on the wall or ceiling and repair it, the most convenient and practical option- this is the use of serpyanka.

For working with slopes, it is important to use a metal grate when a thick layer of plaster is applied. For a thin layer, you can do with fiberglass, but any work with slopes must be done using a reinforcing mesh.

In the case when you need to finish the stove, a massive mesh is used, which is called a chain-link. It is attached to a composition of cement and clay, after which fiberglass is applied to a thin layer. Further, the finishing process goes to the finishing stage.

There are cases when you can do without the use of a reinforcing mesh. But it's still better to use it:

in the presence of joints from various materials - walls made of plasterboard and bricks, erection of partitions adjacent to another material;
on the corners of the rooms, where bearing wall connects to the interior;
in the presence of monolithic concrete surface who is not yet five years old;
there are places where the plaster has been lying for more than 20 years;
in case the mixture has a high degree of shrinkage;
when working with drywall;
if the surface is painted, wallpaper or decorative plaster will be applied to it.

If you have to work with a masking net for the first time, you need to know how exactly it should be applied to the surface. The sequence of work in this case is reduced to:

preparing the base for the mesh;
applying a base layer of putty to the area where the mesh will be applied;
installing the mesh itself;
pressing the mesh into the putty;
leveling the mesh with a spatula so that there are no irregularities or folds on the surface;
covering the paint net with a new layer of putty.

After that, it is imperative to dry the surface until it is completely dry and apply a finishing layer of plaster, finally leveling the surface.

If reinforcement is necessary, then the mesh is not positioned end-to-end, but with an overlap of at least 10 centimeters.

In order to use the mesh correctly, you need to be able to choose it, and for this it is important to know how the main repair mesh options differ.

Putty mesh- material similar to fabric, in which the cell is only 2 by 2 mm, and the density is 60 g per m2. If a mesh with a cell of 5 by 5 mm is taken for work, then the surfaces can be reinforced using a coarser mortar. This mesh can be used both indoors and outdoors.
Serpyanka in structure it has the same appearance as the 2x2 putty mesh, but differs in size, because it is made in the form of a strip. This strip is small in thickness, and the length can vary from 12 m or more. An important feature of such a coating is that one side has an adhesive base, with which it is possible to reinforce cracks on the walls.
Spider web- a material that is not similar to fabric, but obtained as a result of the press of a large amount of fibers. In a professional environment, it is called fiberglass. You can buy it in the form of a roll, the width of which may vary. The minimum is 2 cm and the maximum is 2 meters.

Plaster on the grid is effective way rough wall decoration. But what is the essence of this method, which grid should you choose, and when should you use it? Next, we will try to answer these and some other questions related to the application of plaster to the mesh.

Why do you need a plaster mesh

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

Such surfaces, first of all, 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 allows you to reduce surface cracking, which is especially important if the finishing is done in a thick layer.

Mesh types and their applications

Today in the construction market there are several types of nets. First of all, they differ in the material from which they are made.

For plaster, the following types can be used:

Fiberglass;
Metallic.

If the surface of the wall is flat enough and the plaster will be applied in a thin layer, then a fiberglass reinforcing sheet is 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 meshes, metal meshes come in different types:

Woven;
Wicker;
Welded;
Expanded metal.

Now we will consider the features of each type of material, which will allow us to make right choice when purchasing it.

Woven

This mesh is a fairly flexible fabric made of strong, thin wire. It is realized in large rolls, which makes it quite convenient to transport.

Most often, her and the performance of internal work. The only thing when choosing this material is to pay attention to the section of the cell. Woven plaster mesh 10x10 mm is the best option.

Advice! A prerequisite the use of this canvas is the presence of a zinc coating on it.

Wicker

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

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

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

Welded

The welded mesh is made by connecting the wire with a welding method. Such a canvas has symmetrical square cells.

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

Expanded metal

The plaster mesh of the CPVS is distinguished by a rather complex manufacturing process. It is based on a metal sheet, in which holes are made on a special machine. After that, such a metal is subjected to stretching, as a result of which it turns into a mesh.

The cells are diamond-shaped and staggered. This material is used only in cases where an insignificant consumption of plaster solution for one square meter.

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 for applying plaster to the mesh

Preparation of the base

Despite the use of a mesh, the base must still be carefully prepared before plastering:

First of all, the old coating is cleaned off the wall - paint, plaster, etc.
All flaking and crumbling areas must be removed.
Then the base is cleaned from dust. If there are traces of mold or mildew on the surface, then the wall must be cleaned with a metal 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 microorganisms.

Installation of the mesh

After the base has been prepared and primed, 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 to be plastered.
Next, you need to unfold the roll and cut the canvases of the required size with special scissors for metal.
After all the pieces are prepared, they should be attached to the wall. Plastering mesh installation is usually done with self-tapping screws or construction nails. The canvases should have an overlap of 10 cm. In order for the mesh to be securely fixed, it is necessary to use washers or perforated galvanized tape.

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

I must say that in most cases with internal and, 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 attached to the wall, you need to install beacons with your own hands, thanks to which a flat surface of the walls is achieved. 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 extreme 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 a gypsum solution, which quickly solidifies.
After that, the extreme beacon is installed on the other side of the wall. To keep the rest of the guides in the same plane, you can pull a thread between the extreme beacons.
Further, intermediate profiles are mounted with a step less than the length of the rule, which will allow the tool to rely on them when leveling the wall.

Plastering

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

The instruction looks like this:

Immediately before finishing, you need a creamy consistency.
Then the first layer of plaster is applied, which is called spray. The composition is pounced on the walls with a trowel or ladle. In the process of performing this work, some effort should be applied so that the mixture adheres to the surface, and does not slide down.

The spray layer should be about 1 cm.

After the spray has set, a thicker solution should be prepared and applied to the walls with a trowel. If the required thickness is achieved, then the surface must be leveled using a rule. To do this, the tool should be pressed against the beacons and pulled upwards, which will allow to wipe the solution and remove its excess.
When the plaster has set, you need to remove the beacons and seal up the remaining traces with a solution.
The final step is to align the corners. The joints between the wall and the ceiling, as well as the interior corners, are leveled with an angled trowel. Perforated metal corners are used to finish the outer corners.

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 examined the installation of a metal mesh. If a fiberglass sheet is used, it is usually glued to the wall directly during the plastering process.

Output

Having dealt with the types and types of plaster nets, as well as their purpose, it will not be difficult to choose correct material... However, in order to achieve a positive effect from its use, it is necessary to follow the finishing technology described above.

You can get more information on this topic from the video in this article.

Currently, plaster is ranked among the most demanded finishing materials for interior surfaces of ceilings and walls.

The technology has stepped far forward, and not so long ago, shingles for plaster were used to strengthen the surface of the walls. Now, reinforced painting mesh for plaster is widely used.

1 Features of application and types

Plaster mesh is used in order to securely attach this plaster to the wall, its thickness can be different. The presented wall decoration technology implies the use of those products that have a certificate of conformity.

Typically they have a typical size and aspect ratio of 10 x 10 mm. Such a mesh, having dimensions of 10 × 10 mm, can be attached to the inner surfaces of the walls quite simply and without much difficulty. Plaster mesh, which has an appropriate certificate of quality or conformity, is used to fasten or reinforce walls from the inside of a building.

In this case, the thickness interior walls is not decisive, but the plaster mesh fulfills its bonding function. In most cases, the plaster mesh is 10 x 10 mm. Before you start using it, you must make sure that there is such an accompanying document as a quality certificate.

Product thickness may vary within minor tolerances. Such a product, which is used for plastering on the wall, must necessarily have a certificate.

This certificate confirms the full compliance of the product with all standards and requirements. It should indicate the thickness and dimensions(for example, 10 × 10 mm). Such products can be made using polyurethane or metal, and must be attached to the wall after reading all the relevant instructions.

In this and similar cases, the thickness of the walls does not matter on the quality and pace of work performed. Fastening of a product with dimensions 10 × 10 is carried out using special adhesives, self-tapping screws, screws, as well as other devices, the use of which is permitted by the certificate.

The thickness of the products, in this case, must correspond to the technological conditions. Most of the mesh is realized in the form of rolls and can have different sizes, the most common among them is 10 × 10 mm.

When buying, be sure to pay attention to the quality certificate. Depending on the method of applying plaster to the surface of the walls, the fastening of metal or analogs can be carried out with an orientation towards different ways implementation.

Certificate metal products may differ from the same document related to plastic products.

That layer of plaster on the wall, which is called the bottom one, is reinforced with the participation of the selected mesh product immediately on top of the already applied solution. The applied solution should be of the correct thickness and press down the mesh with a slight degree. The certificate reflects all these manufacturing points in their respective points.

The most acceptable option, during which the last decorative layer will be applied, there will be one during which the reinforcement will be attached to the wiped and dry surface using special devices.

The certificate allows the use of such technologies. In the case when the surface of the walls to be treated does not have a large area, the plaster itself can act as a fastener to the wall.

At the same time, it should be applied to the surface of the walls to be treated in a dotted manner - this will contribute to the reliable fixing of the mesh.

After completing this action, the entire thickness of the plaster layer is spread evenly over the entire surface area. Currently, there are a number of types of products presented, among them it should be noted:

universal (small);
universal average;
universal large;
fiberglass mesh;

plurimu mesh;
armaflex;
syntoflex;
steel;
galvanized.

The presented types of products are distinguished by a wide range of functionality and exhibit a high degree of resistance to impact. high temperatures and harmful chemical attack.

Some of the species presented are characterized by their chemical inertness and can be used for both outdoor and indoor finishing works... These products are distinguished by the presence of artificially reinforced units and are used in those areas where they have an increased load.

2 What is the best mesh to use?

When making a choice of the presented products, the primary parameter is the value of its thickness. Before carrying out work, the lowest point is located, located on the ceiling, and then it is marked using a laser or building level.

After carrying out such manipulations, it will be possible to assess the maximum thickness of the plaster layer, which will subsequently be formed. After a certain result is obtained, a number of certain actions are performed.

In the event that the parameter of the thickness of the plaster will not exceed the value, equal to 20 millimeters, provided that there are no rustics at the ceiling base, you can apply a plaster layer.

After that, you can proceed to the installation of beacons. If there is a presence of rust on the ceiling, or the leading layer has a thickness of 20-30 millimeters, it would be most rational to use a mesh product made using fiberglass.

This is due to the fact that the main purpose of the presented meshes is to protect the entire surface from cracking.

If the layer will have a thickness of 30 millimeters, then it should be applied.

It can with a high degree of efficiency prevent flaking under the influence of its own weight.

If the ceiling is uneven, and the differences in height values are more than 50 millimeters, then the plaster will need to be abandoned altogether.

2.1 Technical nuances of installation and overlay

When buying such a product, you need to take into account the fact that the mesh size should be slightly larger than 5 × 5 millimeters, with a density value from 110 to 160 g / m².

The presented material in most cases should have such a quality as resistance to the harmful effects of alkalis. At the same time, the indicator of the minimum thickness of the plaster layer when using a mesh made using fiberglass should be equal to 3 millimeters, with a maximum value of 30 millimeters.

Before proceeding with the work, the product must be trimmed in compliance with the orientation to the proportions and dimensions of the canvas itself. The value of the size of the canvas will directly depend on the location of the mesh. It can be longitudinal or transverse.

If there is rusticity on the ceiling, then the mesh is located there in one solid canvas with an orientation to the location of each of the seams. In the event that there are no rusts, there will be no requirements for the special arrangement of products.

It is enough only that when performing work, the entire working surface will be evenly covered with a mesh.

Trimming is best done with a margin of 10-15 centimeters in order to strengthen the existing joints located between the walls and the ceiling. At the beginning of the work carried out, the entire surface is covered with the very first putty layer. On top of it, a plaster mesh is applied and slightly pressed.

Next, the second layer is applied. According to the regulations, such an operation can be carried out in one go. Alternatively, you can wait for the intermediate layer to dry out. The fiberglass mesh is designed to be attached to the wall with screws or staples, the plaster will lie on top.

The presented method is applicable when it is planned to create a thin plaster layer. Then the product will be located right in the middle of the plaster layer.

If the layer thickness exceeds 10 millimeters, then the mesh can slide to the edge, and not the plaster will be reinforced, but only its surface. The initial working steps are carried out taking into account the following algorithm.

Fastening the mesh under the plaster must be done according to certain rules. After all, the appearance and durability of the entire plane will depend on this.

Today we will consider in detail how to fix the mesh under the plaster. Although this is not a difficult job, there are certain rules and it is worth doing them. Also on the video in this article and the photo are possible options for doing this work.

Fastening the plaster mesh to the wall is done according to certain rules. only first you need to choose it correctly. The manufacturer has made sure that there is a wide selection of fiberglass mesh on the market.

You can see the photo different types mesh. But the most important thing is to choose the right one. How to attach the mesh under the plaster and how to choose the right one will now be considered in detail.

When choosing a mesh, you should pay attention to the following nuances:

The mesh should have good resistance to alkaline solutions. To do this, it must be placed in such a solution for 25 days, and then tested for rupture. The reduction in strength should be minimal.
The mesh should be tested for tensile strength... To do this, you need to take a small piece of mesh and try to crush it into a ball, after which it should take its original shape.
Attention should be paid to the quality and size of the cells.
All the main characteristics of the product are indicated in the passport. manufacturer indicating the tests performed.

Attention: Do not forget to immediately purchase the fasteners, because the mesh should adhere to the surface and not puff up.

Fastening the plaster mesh

The maximum effect can only be obtained when the fixing of the plaster mesh is done correctly. Everything can be done with your own hands, then the price of the work will not be significant.

It must hold firmly on the plane, because it will not have a small weight on it. If this effort is performed, then it will be possible to say with confidence that the plaster layer, during operation, will not fall off the main surface and will not crack.

In spite of a large number of types of this coating, the fastening of the plaster mesh is carried out as tightly as possible to the plane. For this, plastic dowels with self-tapping screws can be used, to which the mesh is attached using metal, galvanized wire. In this case, the reliability of the plaster layer will depend on the reliability of the fastening of the metal mesh.

Metal plastering mesh

We will consider in more detail how to fix the plaster mesh.

It is also presented on the construction market in a wide range:

By types: welded, woven, mesh-netting, perforated, reinforcing, etc.
By cell shape and size as well as location and structure.
By the size and diameter of the metal wire.
By the presence of coating (galvanized, polymer).

Attention: The range of metal mesh is so large that it can be used in almost all areas of repair and construction work, in which you cannot do without a reinforcing mesh.

Metal mesh (see. Steel plastering mesh - types and applications) is able to maintain its original shape both during its laying and during operation. This allows you to get better quality plaster surfaces with an increased service life. All reinforcing meshes made from other materials do not have such high stability, which limits their scope.

Based on the above, we can safely say that the metal mesh is more versatile, and it can be used:

On almost all types of surfaces and with the use of all types of plaster mixtures and mortars, while plastic mesh it is intended for use with gypsum plasters; it is not recommended to use it with all other types of mixtures.
With different layers of plastering solutions applied to the surface. With its help, it is possible to eliminate unevenness differences from 6 cm or more. Other types of reinforcing meshes, including fiberglass, can be used with an application thickness of no more than 3 cm.
If a plaster mesh made of galvanized metal or with a polymer coating is used, then a reliable and durable surface can be obtained. This mesh has excellent moisture resistance, wear resistance, strength, etc.

Sequence of fastening the metal mesh:

First you need to measure which section of the mesh you want to fix. Typically, this will be from floor to ceiling. This size is transferred to the mesh, after which it is cut using metal scissors (if it is a thin mesh) or using a grinder, if it is a chain-link mesh, with a wire thickness of 2 mm or more.

Note: If the mesh is mounted on a wall, the top edge is fixed first. To do this, you can drill a couple of holes, insert into them along the dowel and screw in through the self-tapping screw. It is possible with a wide hat. After that, the cut piece of mesh is simply put on the self-tapping screws and pressed with the same self-tapping screws. After that, it can be thoroughly fixed without any problems.

If the mesh needs to be fixed on the ceiling, then everything is much more complicated here and one person cannot cope with it. Fastening can be done in the same way, but first the four corners of the mesh are fixed, after which it can be finally fixed without any help. But if you take it in general, then you can't do without an assistant.
The fastening frequency depends on the size of the mesh and the thickness of the mesh material. In all attachment points, the mesh can be in contact with the main surface, and in the intervals between the attachments it must move away from the surface, otherwise the reliability of the plaster layer will be reduced.
Before strengthening the mesh, all debris is removed from the surface and dust is swept away. Before applying the plaster layer, base surface should be wetted for better adhesion.
A correctly fixed mesh should be stretched like a string and not vibrate in places where there are no fastening elements, otherwise, during operation, voids may form under the mesh, which will have a negative impact on the final result.

Fiberglass Plastering Mesh Applications

Now let's talk about how to fix the plastic plaster mesh.

If there is a need to reinforce the surface layer of the plaster, regardless of the type of building.
It is used to reinforce waterproofing layers of roofs and floor slabs.
It is necessary to enhance the mechanical strength of self-leveling cast floors.
It can be used to reinforce plaster mortars intended for surface preparation for ceramic tiles.
It will be needed to reinforce plaster surfaces applied to materials with different coefficients of thermal expansion.
It is very important when applying a plaster layer to the lower plinth of a building.

The technology of laying the reinforcing mesh is very simple and anyone can do it:

Plaster nets with a density of 145g per square meter and a mesh with a density of 165g per square meter are very popular among builders. These meshes are mainly used to reinforce the plaster layers of the facades of various buildings.
The consumption of the reinforcing mesh is 1.1 linear meters per 1 square meter of area, with a mesh width of 1 meter. Fiberglass meshes are used to strengthen plaster layers in places where completely different materials are used, for example, brick and wood. It allows you to perform high-quality work in places where small deformation changes are possible, in the presence of plastic corners, in the places where the plaster layer adjoins the insulation materials of window and door openings.
The technology of laying fiberglass mesh requires that it be embedded in a fresh layer of plaster to a depth of about 5 mm. In this case, it will be in the middle of the applied plaster layer, which guarantees high strength and solidity of the plaster layer.

How to fix fiberglass mesh

Fiberglass mesh is as popular as metal mesh. Even insulation of a building with foam plastic is not complete without the use of fiberglass mesh.

So:

Such a mesh is mounted after the fastening is completed. foam boards to the base surface.
A rough layer of plaster is applied to the surface of the foam. Work is carried out in small areas, since the mixture tends to harden quickly.
The mesh is cut to size and applied to the surface that has not yet hardened. After that, a wide spatula is taken, and the mesh is leveled and, as it were, pressed into the freshly applied putty or plaster.
After that, time should be given for the surface with the mesh to adhere well. Usually on the second day, work continues on this surface. First of all, you need to walk over the surface with a putty knife and remove any burrs or bumps.
When installing the mesh, you need to ensure that each strip is located on the previous strip with an overlap of 15-20 cm, otherwise cracks may appear during operation.
After the excess debris has been removed from the surface, you can start applying the finishing layer.
Here is a special case of the use of fiberglass plaster mesh, but the scope of its use is much wider.
When carrying out repairs in private houses with a solid service life, there is absolutely nothing to do without fiberglass mesh. This applies to both walls and ceilings.
When carrying out repairs in multi-storey buildings, and especially during puttying on the ceiling, where there are significant differences due to unevenly laid floor slabs, it is also recommended to use a fiberglass mesh. There are times when it does not help and you have to mount drywall.
If the walls are gypsum blocks and there is a need to cover them with a layer of putty, then the plaster mesh will not be superfluous.

You now know how to attach the plaster mesh to the wall. The instruction will help you choose it correctly and then fix it with high quality.
