Plaster mesh for internal. How to plaster a façade using a mesh using technology

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 Various plaster compositions are used on plastered surfaces. 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.

Application 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. Slats are nailed onto wooden walls, 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, flat 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, the mesh and metal fastenings if they don't 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.

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

Peculiarities

Modern renovation cannot do without the use of plaster, because the walls, floor and ceiling are finished form must be completely smooth, be heat and sound insulated, and serve for a long time and reliably. If you do not apply a layer of plaster to the rough wall, you will not be able to achieve the desired effect. In order for the layer of plaster to hold securely and not crack or fall off, it is important to strengthen it. The mesh is just such a fastening mechanism.

If previously more primitive and inconvenient materials were used to strengthen the surface for plaster, then with the advent of a mesh made of new materials, working has become much more convenient and faster. Plaster mesh can be made of various materials, have different cell sizes, shapes, and weight of the canvas. All this leads to different results from its use.

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

Almost every hardware store now has a selection of mesh for plaster, which have different lengths, which makes it possible to select the optimal quantity required material for carrying out work. The principle of working with it is quite simple, which makes its use more popular for renovating all rooms in a house, apartment, office, obtaining excellent final results.

Plaster mesh is very important element for repair work, because with its use, finishing the walls is 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 tears at the joints or along the canvas itself. Painted walls are most susceptible to showing through imperfections that appear on them, Therefore, when choosing 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 kinds influences and unpleasant environmental factors.

Kinds

Due to the great popularity of the material, it was necessary to create a certain number of options that would allow puttying on different surfaces as convenient and efficient as possible. Thus, there are such types of mesh as:

Masonry mesh- This construction variety, which 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 mixture. It is convenient to use in any area due to the optimal cell size, which is 6 by 6 mm.
Medium universal. The material of manufacture is polyurethane, as in the previous case, but the size is different - 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 glass fibers, which are processed in a special way. The cell size is not large and is 5 by 5 mm. This option easily tolerates temperature differences, exposure chemical elements, at the same time it has high strength and can withstand the heavy weight of the plaster. This option is most often used in work because it is lightweight, convenient and does not have special contraindications for use.
Plurima– polypropylene biaxially oriented mesh with a cell of 5 by 6 mm. This option is also convenient to use because it is not exposed to chemical influences, is lightweight and can be used both indoors and outdoors.

Armaflex– a polypropylene type of mesh with reinforced nodes. The cell in this case is quite long and measures 12 by 15 mm. The mesh has high strength, which is why it is most often used where the putty layer is very large.
Syntoflex– polypropylene variety with a cell of 12 by 14, 22 or 35 mm. Lightness of the material and lack of reaction to chemical substances allow you to work with the mesh both indoors and outdoors.

Steel version- these are soldered rods of steel. The size of the cells can be very diverse. Is used for interior decoration, because under the influence of precipitation, steel will not last long and will begin to rust.
Galvanized version involves intertwining galvanized rods with each other, which is then soldered. This durable material, from which you can level the surface in any conditions, both indoors and outdoors.

Reinforcing wall finishing assumed the use of metal meshes, which have certain design options - these are welded, woven and expanded metal varieties. Cells can be of different sizes, due to specific task, for which rods with different thicknesses and the type of their connection. The resulting mesh has high strength and physical and mechanical characteristics. Wire mesh is used indoors because it does not tolerate high levels of moisture and under its influence metal corrosion can begin.

Galvanized variety it is applied for external works 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 fastening is welding.

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

Metal grid The expanded metal type can be made in any way. Due to the absence of welding points, the resulting product is durable.

A mesh is used for plastering the inner surface of walls, where the layer of material is no more than 30 mm.

Steel mesh has its advantages, but progress does not stand still and it has been replaced by new material. Plastic mesh is a modern type; 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 plinths. This material has no problems with a wide temperature range; it can even be used to create a thermal insulation layer.
Fiberglass 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 This material is not dangerous; rotting processes are also avoided, which is why this type is used most often and is considered the main one in the work.

The polyurethane variety is also universal.. It is very convenient to use it in large rooms. But the biaxial polymer mesh is the newest material available in this industry. Due to its elasticity and the absence of contraindications for use, it is universal remedy for communications that conduct current when working on various facades.

Polypropylene mesh is very durable and can withstand a lot of weight, so it is recommended to use it to strengthen bridges and roads.

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

The mounting mesh for plaster is a very convenient invention that has made the repair process simpler and significantly improved its results. Types of meshes with different sizes cells 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 service life of a particular object.

Which one to choose?

If we consider metal type grids, then there are criteria by which you need to make a choice towards one option or another. These include:

Qualitative characteristics of the raw materials that are taken to make rod or wire. It is advisable to have information about the grade of steel alloy from which the mesh is made, which will show how high quality the product is.
The cost of stacks will be higher for small traders, so for large quantities you should contact enterprises that deal with this. Large product turnover makes it possible to recoup it, which means not to charge too high prices.
The quality of the rods themselves, the presence of galvanized coating. Non-galvanized mesh can be used for interior works, but if it is used for outdoor purposes and not covered special composition, then it will soon rust and traces of corrosion may reach the outer layer of the finish.
You need to choose the right type of mesh. If it is welded, then it will be better to hold the plaster on itself than twisted one. This is important when work is carried out with brick wall or from aerated concrete outside the house, where the layer of plaster can reach significant sizes.
The rods must have a clearly standardized thickness of the rods, therefore, when choosing a mesh, you need to pay attention to GOST standards in each package.

The plastic version of the mesh for plaster is not inferior to any of the above options; it can be used on any surface, inside or outside, for the base and facade. The only case when it is worth turning to a metal mesh is if there is a thick layer of plaster, which has considerable weight; in all other situations, modern meshes will be much more convenient to use.

Usage plastic version It also involves choosing the desired cell size, which often comes down to 6 by 6 mm, but you can choose another option depending on your wishes and ease of use.

Dimensions

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

For masonry type mesh most convenient size The cells are 5 by 5 mm. The main production material is polymers.
For universal type There are several options - from a small cell 6 by 6 and a medium cell 13 by 15 to a large cell 22 by 35 mm. The material for production is polyurethane. Used for interior decoration.
For fiberglass mesh the optimal cell size will be 5 by 5 mm, and it is made from fiberglass material.
Plurima 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 if necessary, you can find more dimensions. This mesh is made from rods that are connected by soldering, which ensures long service life and reliability of the finished surface.
Armaflex Most often it is made with cells 12 by 15 mm and is used in cases where a thick layer of mortar is used in the work.

At the syntoflex There is a fairly large range of cells that can be used in work - these are 10 by 10, 12 by 14, 20 by 20, 22 by 35. It is made of polypropylene.
For steel mesh The cell size can be different, but the most popular is 20x20 mm. It is made from rods made of metal, which are soldered together. To fix it on the surface, you need a corner.
For plastic mesh There are no specific standards for cell size. It is most often used to fasten foam plastic and sit on glue, after which it is treated with finishing putty. After this, the process can be considered complete.

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

Installation

Since there are many varieties of plaster mesh, there are also several ways to attach it. The most popular of them are:

applying the plaster mixture;
use of self-tapping screws;
use of dowel nails;
fastening with screws.

If the first layer of plaster is applied, the mesh is simply pressed into it. With these actions you can effectively level the wall and get a strong coating. But for decoration, you need to secure the selected canvas using fasteners. If such a zone is small in size, then it can be applied to certain areas. For a painting mesh, a small layer of solution is enough.

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

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

The process of smoothing the mixture over the mesh proceeds 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 metal mesh, then the sequence of work is different:

cleaning from grease, washing the surface and wiping with a damp cloth;
dividing the mesh into pieces of the desired size using metal scissors;
preparing holes for dowels at a distance of 30 cm from each other;
using dowels, screws and mounting tape, you need to secure the mesh to the wall surface;
a new section of mesh is laid with an overlap of 10 cm;
after this comes the installation of beacons and work on them.

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

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

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

Work is carried out until the entire ceiling is covered, after which you need to wait until the surface is completely dry and begin finishing using any convenient way. By following the above rules, you can easily and correctly renovate any room.

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

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

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

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

To work with slopes, it is important to use a metal grating when a thick layer of plaster is applied. For a thin layer, you can get by with fiberglass, but any work with slopes must necessarily use reinforcing mesh.

When it is necessary to finish the stove, a massive mesh called chain-link is used. It is attached to a composition of cement and clay, after which it is thin layer fiberglass is applied. Next, the finishing process moves to the finishing stage.

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

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

If you are working with a painting mesh for the first time, you need to know exactly how it should be applied to the surface. The sequence of work in this case comes down to:

preparing the base for the mesh;
applying a base layer of putty to the area where the mesh will be applied;
installation of the grid itself;
pressing the mesh into the putty;
leveling the mesh using a spatula so that there are no unevenness or folds on the surface;
covering the painting mesh with a new layer of putty.

After this, be sure to dry the surface until completely dry and apply finishing layer plaster, finally leveling the surface.

If reinforcement is necessary, then the mesh is not placed 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 options for repair meshes differ.

Putty mesh- a fabric-like material with a cell size of only 2 by 2 mm and a density of 60 g per m2. If you use a mesh with a cell of 5 by 5 mm for work, then you can reinforce the surfaces using a coarser solution. This mesh can be used both indoors and outdoors.
Serpyanka the structure 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. Important feature Such a coating is that one side has an adhesive base, which can be used to reinforce cracks in the walls.
Spider mesh- a material that is not similar to fabric, but obtained as a result of pressing a large number of fibers. IN professional environment is called fiberglass. You can buy it in the form of a roll, the width of which can vary. The minimum is 2 cm, and the maximum is 2 meters.

Currently, plaster is considered one of the most popular finishing materials for internal surfaces of ceilings and walls.

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

1 Application features and types

The mesh for plaster is used to securely attach this plaster to the wall; its thickness can be different. The presented wall finishing technology involves the use of those products that have a certificate of conformity.

As a rule, their typical size and aspect ratio is 10x10 mm. Such a mesh, having dimensions of 10x10 mm, can be mounted on the internal surfaces of walls quite simply and without any particular difficulties. Plastering 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 mesh for plaster performs its fastening function. In most cases, the mesh for plaster has dimensions of 10x10 mm. Before you start using it, you must make sure that you have an accompanying document such as a quality certificate.

Product thickness may vary slightly permissible limits. Such a product is used for plastering on the wall and must have a certificate.

This certificate confirms the product’s full compliance with all standards and requirements. It should indicate the thickness and dimensions(for example 10x10 mm). Such products can be made using polyurethane or metal, and should be attached to the wall after reading all the relevant instructions.

In this and similar cases, the thickness of the walls does not affect 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 allowed by the certificate.

The thickness of the products, in this case, must correspond to the technological conditions. For the most part, the mesh is sold in the form of rolls and can have different sizes, the most common among them is 10x10 mm.

When purchasing, be sure to pay attention to the quality certificate. Depending on the method of applying plaster to the surface of the walls, fastening metal or analogues can be carried out with a focus on different methods of 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 layer, is reinforced with the participation of the selected mesh product immediately on top of the already applied mortar. The applied solution must have required thickness and press the mesh lightly. The certificate reflects all these production points in their respective paragraphs.

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

The certificate allows the use of such technologies. In the case when the surface of the walls being treated does not have large area, the plaster mortar 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 help securely fasten 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;

plurim 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 exposure high temperatures and harmful chemical exposure.

Some of the presented species are characterized by their chemical inertness and can be used for both external and internal finishing works. These products are distinguished by the presence of artificially reinforced components and are used in areas where they are subject to increased load.

2 Which mesh is best to use?

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

After such manipulations, it will be possible to conduct an assessment maximum thickness plaster layer, which will subsequently be formed. After a certain result is obtained, a series of specific actions are performed.

In the case when the plaster thickness parameter will not exceed the value equal to 20 millimeters, provided there are no rusts at the ceiling base, a plaster layer can be applied.

After this, you can proceed to installing beacons. If there are rusts on the ceiling, or the leading layer is 20-30 millimeters thick, 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 the formation of cracks.

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

It will be able to highly effectively prevent peeling under the influence of its own weight.

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

2.1 Technical nuances of installation and application

When purchasing such a product, you need to take into account the fact that the cell size should be slightly larger than 5x5 millimeters, with a density value of 110 to 160 g/m².

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

Before starting work, the product must be trimmed in accordance with the proportions and dimensions of the canvas itself. The size of the canvas will directly depend on the location of the grid. It can be longitudinal or transverse.

If there is rust on the ceiling, then the mesh is located there as one solid sheet with orientation to the location of each of the seams. In the case where there are no rustications, there will be no requirements for a special arrangement of products.

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

It is best to trim with a margin of 10-15 centimeters in order to strengthen the existing seams located between the walls and ceiling. At the beginning of the work, the entire surface is covered with the very first putty layer. A plaster mesh is placed on top of it and slightly pressed in.

Next, the second layer is applied. According to the regulations, such an operation can be carried out in one go. Or you can wait until the intermediate layer dries. The fiberglass mesh is designed to be attached to the wall with screws or staples, and the plaster will go 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, the mesh may slide to the edge, and not the plaster will be reinforced, but only its surface. The initial working stages are carried out taking into account the following algorithm.

Attaching 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 attach the mesh under the plaster. Although this is not hard work, but it is carried out according to certain rules and they are worth following. Also in the video in this article and photo possible options performing this work.

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

You can see photos of different types of mesh. But the most important thing is to choose it correctly. We will now consider in detail how to attach the mesh under the plaster and how to choose the right one.

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

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

Attention: Do not forget to immediately purchase fasteners, because the mesh must adhere to the surface and not bulge.

Fastening the plaster mesh

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

It must stay firmly on the plane, because there will be quite a bit of weight on it. If this effort is made, then we can say with confidence that the plaster layer, during operation, will not fall off the main surface and will not crack.

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

Plaster mesh made of metal

Let's look at how to attach the plaster mesh in more detail.

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

By type: welded, woven, mesh, perforated, reinforced, etc.
By cell shape and size, as well as location and structure.
According to the size and diameter of the metal wire.
Depending on the presence of coating (galvanized, polymer).

Attention: The range of metal mesh is so wide that it can be used in almost all areas of repair and construction work, in which it is impossible to do without reinforcing mesh.

Metal mesh (see Plaster steel mesh - types and applications) is able to retain its original shape both during its installation and during operation. This allows us to obtain higher quality plaster surfaces with an increased service life. All reinforcing meshes made from other materials do not have such high stability, which narrows their scope of application.

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

On virtually all types of surfaces and using any type of plaster mixtures and solutions, while plastic mesh designed with gypsum plasters, it is not recommended to use it with all other types of mixtures.
With different layers plaster solutions applied to the surface. With its help, you can eliminate differences in unevenness of 6 cm or more. Other types of reinforcing mesh, 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 polymer coating, then you can get a reliable and durable surface. This mesh has excellent indicators of moisture resistance, wear resistance, strength, etc.

Sequence of fastening the metal mesh:

First you need to measure which piece of mesh you need to secure. 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.

Attention: If the mesh is attached to the wall, then the top edge is fixed first. To do this, you can drill a couple of holes, insert a dowel into them and screw them in with a self-tapping screw. Possible with a wide hat. After which, the cut piece of mesh is simply put on the screws and pressed with the same screws. After this, it can be firmly secured without any problems.

If the mesh needs to be fixed to the ceiling, then everything is much more complicated and one person cannot cope with it. Fastening can be done according to the same scheme, but first the four corners of the mesh are fixed, after which it can be finally fixed without outside help. But if you take it in general, you can’t do without an assistant.
The frequency of fastening depends on the size of the cells and the thickness of the mesh material. At all fastening points, the mesh can be in contact with the main surface, and in the spaces between fastenings 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, the base surface should be moistened for better adhesion.
A correctly fixed mesh must 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 Negative influence to the final result.

Application of fiberglass plaster mesh

Now let's talk about how to attach a plastic plaster mesh.

If there is a need to strengthen the surface layer of 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 floors.
It can be used to strengthen plaster mortars intended for preparing the surface for laying ceramic tiles.
It will be needed for reinforcing plaster surfaces applied to materials with different coefficients of thermal expansion.
It is very important when applying a layer of plaster to the lower plinth of a building.

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

Plaster mesh with a density of 145g per square meter and mesh with a density of 165g per square meter. These meshes are mainly used to reinforce plaster layers of facades of various buildings.
The consumption of reinforcing mesh is 1.1 linear m per 1 square meter of area, with a mesh width of 1 meter. Fiberglass mesh is used to strengthen plaster layers in places where absolutely various materials, for example, brick and wood. It allows you to produce quality work in places where slight deformation changes are possible, if there is plastic corners, in places where the plaster layer adjoins insulation materials window and door openings.
The technology for 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 secure fiberglass mesh

Fiberglass mesh is no less popular than metal mesh. Even insulating a building with foam plastic is not complete without the use of fiberglass mesh.

So:

This mesh is installed 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 on 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 this, a wide spatula is taken, and the mesh is leveled and, as it were, pressed into the freshly applied putty or plaster.
After this, you should give time for the surface with the mesh to set well. Usually on the second day work continues on this surface. First of all, you need to go over the surface with a spatula and remove all burrs or bumps.
When installing the mesh, you need to ensure that each strip overlaps the previous strip with an overlap of 15-20 cm, otherwise cracks may appear during operation.
After excess debris has been removed from the surface, you can begin applying the finishing coat.
Here is special case applications of fiberglass plaster mesh, but the scope of its use is much wider.
When carrying out repairs in private houses that have a long service life, there is nothing at all to do without fiberglass mesh. This applies to both walls and ceilings.
When carrying out repairs in multi-storey buildings, and especially during puttying work on the ceiling, where there are significant differences due to unevenly laid floor slabs, it is also recommended to use fiberglass mesh. There are times when it doesn’t help and you have to install drywall.
If the walls are gypsum block and there is a need to cover them with a layer of putty, then a plaster mesh will not be superfluous.

You now know how to attach a plaster mesh to a wall. The instructions will help you choose it correctly and then secure it properly.

Plaster mesh is universal material. Used this remedy in a variety of areas of construction and repair. Efficiency individual types plaster mesh is determined by the materials of its manufacture and design features.

Purpose

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

The use of the material helps create a textured relief, which serves as the basis for the durable installation of the leveling plaster layer. The presence of a cellular structure makes it possible to effectively bind solution particles. Thanks to this, the formation of a durable monolithic surface becomes possible.

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

Areas of use

Currently, plaster mesh is actively used:

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

Material selection

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

In cases where the plaster layer is up to 20 mm thick, it is quite possible to reliably veneer surfaces without using a plaster mesh.
If the facing layer in the form of plaster is about 20-30 mm, in this case it is advisable to fasten the plaster stack from fiberglass. Main purpose similar products is to create a protective layer that protects surfaces from cracking.
Laying plaster in a layer of more than 30 mm necessarily requires the use of a metal plaster mesh. This decision protects the facing layer from peeling.
If there are extremely uneven surfaces with recesses, where differences in the facing layer are more than 50 mm, it is recommended to completely abandon plastering.

Installation of metal reinforcing mesh

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

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

It is recommended to attach the plaster mesh starting from the ceiling. The upper side of the canvas is secured with self-tapping screws along its entire length. A piece of galvanized mounting tape is first placed under each self-tapping screw head. Wide washers can serve as a worthy alternative to tape. However, such a solution cannot be called beneficial in terms of cost savings.

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

Laying fiberglass reinforcing mesh

The process of installing fiberglass plaster mesh is much easier compared to attaching a metal reinforcing base. To securely fasten the fiberglass plaster mesh to the desired surface, it is enough to use self-tapping screws. Using such fasteners, the upper edge of the mesh is first processed, and then the entire perimeter of the reinforcing material.

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

It is worth noting that it is most convenient to unwind rolls of material and secure the sheets parallel to the floor plane along the wall. It is better to start installing fiberglass plaster mesh from one of the upper corners. As in the case of laying 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 laying the mesh in solid sheets along the entire length of the treated surface. Therefore, when cutting material, you must try to create a minimum number of small individual pieces.
