Overview and advice on choosing reinforcing meshes for wall plastering. Facade reinforcing mesh

The method of mounting a polymer mesh involves a number of steps.

1. At the first stage, the foundation is prepared. Preparatory work include surface cleaning and priming.
2. The next step is to measure the wall surfaces and cut the canvas in accordance with the measurements taken and add a margin of about 10 cm (for overlapping the joining of the canvases).
3. After that, the preparation of the adhesive-based composition is carried out.
4. The main stage is the application of the initial plaster layer with a density of 3-5 mm with the indentation of the paint grid into the solution.
5. After the initial layer dries, the surface is covered with a primer and the final layer of plaster is applied, leveling is carried out by the rule.
6. At the last stage, the dried wall surfaces are sanded.

A few useful quick tips allow you to do the job of plastering walls as efficiently as possible.

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

The use of reinforcing plaster mesh in the process of execution internal works for plastering wall surfaces allows you to do it efficiently. The presence of the mesh prolongs the service life of the finishing material, the main thing is to choose the right type of reinforcing mesh, based on the conditions of its use.

Modern standards for interior and exterior surfaces have very high requirements for aesthetics, durability and reliability of the finish. Wall plaster mesh significantly improves the quality, which generally has a beneficial effect on the final result. And although the reinforcing layer is not visible, it is he who ensures the stability of the structure, preventing the plaster from cracking.

In the article, we will analyze the questions: what kind of mesh is used for plastering walls, what type is used in a particular case, and why should the plaster layer be reinforced.

Reinforcing mesh for wall plastering - types and characteristics

V finishing works ah apply several : , and various options mixtures with a change in the proportions of the components and the addition of additives to improve the quality of the solution. For each type of work, the reinforced grating is selected individually. It depends on the:

• selected mixture;
• the material from which the surfaces are made -, etc .;
• operating conditions of the coating: outdoor (,), indoor, in rooms with a difficult microclimate (unheated, bathrooms, etc.)

Reinforcing mesh for plastering corners

We can distinguish the following types of reinforcing gratings, the most popular in the building materials market:

• Masonry - plastic mesh for plaster, made of polymers, cells of a standard size 5 * 5 mm, used in brickwork.
• Universal mini - made of polyurethane, cells 6 * 6 mm, suitable for both rough plaster and fine finishing work. Medium, cell 13 * 15 mm, for finishing up to 30 mm thick on not large areas. Large with a cell of 35 * 22 mm - a mesh for plastering the facade, it reinforces large areas for a thick layer of plaster: the outer walls of houses, warehouses, etc.

Fiberglass mesh for facade plastering - universal for all types of work

• Construction mesh for plaster made of sterol fiber, standard size cells 5 * 5 mm, tolerates chemical and thermal effects well, durable. This type almost universal, its application has no restrictions.

• Plurima polymer mesh for plaster, oriented on 2 axes, with a cell of 5 * 6 mm, light, inert to chemical attack, used for interior and exterior work.
• Polypropylene armaflex grating, distinguished by reinforced knots, mesh size 15x12 mm. Heavy-duty, used in areas where heavy loads are placed on the plaster.
• Syntoflex made of polypropylene, cell 14*12 mm or 35*22 mm, not afraid of exposure chemical environment, lightweight, durable. Suitable for plaster internal walls and facades.
• Steel grating is made of metal rods of different cross section, soldered at the nodes, the cells are from small to very large, it tolerates mechanical loads well, but it should only be used for internal plaster, as it is susceptible to corrosion under the influence of atmospheric phenomena.
• Metal mesh for wall plastering, galvanized, made of rods different section, knots are welded, the size of the cells is different. Universal for outdoor and indoor work, not afraid of difficult operating conditions.
• Chain-link - a metal mesh for plastering external and internal walls, under a thick layer, distinguishing feature- cells are woven, come in different sizes.
• Expanded metal mesh. Made from whole sheet metal, after punching holes, it is pulled out to get diamond-shaped cells in a checkerboard pattern. It is used mainly under a thin layer.

Expanded Galvanized Grating

Selection conditions

The grid for wall plastering is also needed so that as much as possible, and the solution does not exfoliate from the surface, cracks do not go after drying. This is the skeleton that provides the strength and integrity of the structure.

If there are rusts on the walls, ceilings, facades - depressions, grooves, recesses, usually reaches 30 mm, in such works glass fabric reinforcement is used more often than others, which is used with a layer thickness of 3 to 30 mm and prevents.

If the thickness of the finish is more than 30 mm, it is advisable to use metal gratings, they will prevent the heavy layer from peeling off the surfaces. Metal meshes are relevant when plastering very uneven surfaces and when using.

Over time, corrodes plastic mesh, it is usually applied under a small thickness. A canvas with a mini cell of 2-3 mm is used for finishing putty walls.

Welded grating for finishing brick surfaces

If earlier shingles were used for, now an alternative to it is a chain-link mesh, which has proven itself over time. It is also actively used for finishing walls with insulation.

Fiberglass fabric for reinforcement comes in different densities, it is convenient that it is produced in compact rolls, it is applicable for walls, ceilings, self-leveling floors. It is moisture resistant, which allows it to be used for swimming pools, to reinforce the roof with a water-repellent layer. The elasticity and strength of the material make it possible to use it for sealing gaps between plates and sealing cracks in the plaster layer, in this case good decision serpyanka will become - self-adhesive tape different widths. Due to its thermal and frost resistance, fiberglass cloth is also used as a facade mesh for plaster.

Reinforcement is mandatory if the width of the slopes is more than 150 mm, with a plaster thickness of up to 30 mm, fiberglass is used, a thicker layer is applied to metal gratings.

For plastering fireplaces and stoves, metal reinforcement is often used, it is nailed between the joints of the masonry. V Lately in these works, a fiberglass sheet is often used, glued with a liquid solution to the surface. The choice depends on the thickness of the finish.

Mesh for plastering external walls: woven from galvanized wire, with a cell of 10 mm 2, chain-link - for large areas. Welded mesh facade under plaster - perfect solution for new buildings, where the walls will shrink. If the thinnest layer of plaster is required, fiberglass, expanded metal and polymer mesh will do.

For a thick layer of screed, it is better to use a metal grate

The surface of the enclosing structures, even with their impeccable construction, needs to be leveled, the classic of which is plastering. The plaster coating is often reinforced - with a mesh of various materials certain cell size. This additional stage complicates and increases the cost of the process, but under certain circumstances it cannot be dispensed with.

Consider the role of reinforcement in the plaster coating, and which reinforcing mesh to give preference to in a particular case.

Functions of reinforcement in plaster

Reinforcement of the plaster layer is an effective, time-tested operation to improve the performance of the leveling coating.

Reinforcement in plaster performs the following functions:

1. It makes it possible to form a plaster coating, the thickness of which exceeds the maximum allowable value for the mixture used. The need for this arises when, after marking on the plastered wall of the lighthouse plane, it turns out that the required thickness of the leveling layer does not fit into the characteristics of the mixture used.
2. Ensures the integrity of the plaster layer, preventing cracking or neutralizing its consequences. The specific gravity of the plaster is significant, so cracks in the coating are dangerous, especially if they form in high-lying areas that do not have support under the leveling layer (above window and doorways) - the collapse of the finish is fraught with injury. The reinforcing mesh, even when the finish is peeled off, will prevent its collapse.
3. Increases the bearing capacity of the plaster. Delamination of the plaster coating in case of loss of adhesion to the base can cause the collapse of the finish on the solid surface of the wall. This can be provoked by the load from interior elements mounted on thick-layer plaster (shelves, cornices) that are not connected with the supporting base. Reinforcement gives the plaster layer additional bearing capacity.

Plaster from any mixture with a thickness of more than 3 cm must be reinforced to avoid delamination.

The functionality of plaster contains the answer to the question of when it is reinforced:

1. When performing a thick-layer coating - locally or over the entire area;
2. If the house is located near objects that have a vibrational effect on it;
3. In the presence of a factor of periodic uneven shrinkage of the building (re-planning in the apartments of frame houses);
4. To provide additional coverage bearing capacity, including for the installation of interior items and household equipment.

Types of reinforcing mesh

In the middle of the last century, the reinforcement of plaster was carried out by laying it on shingles, which compensated for the lack of adhesion to the base and reduced the likelihood of coating collapse. But the installation of shingles is a time-consuming operation, and the mounted reinforcing grating, with its modest physical characteristics, was also vulnerable to moisture and microorganisms.

Today, plaster is reinforced with special meshes, which differ in the material of manufacture, production method and mesh size, on which the scope of their application depends.

The main classification of reinforcing meshes - according to the material of manufacture:

• metal;
• polymeric;
• fiberglass.

Consider these materials in terms of suitability for reinforced plastering of various wall surfaces.

metal mesh

Of all the meshes used in construction, the most durable are metal meshes, which, according to the manufacturing method, are of the following types:

1. Woven - from low-carbon, galvanized or stainless steel, brass;
2. Chain-link mesh - ordinary, galvanized or polymer-coated steel;
3. All-metal expanded metal mesh (TSPVS, "cut") - made of ordinary or galvanized steel;
4. Welded - plain or painted steel.

Grids also differ in wire thickness and mesh size.

Metal mesh plaster stone walls they reinforce with significant level differences - more than 4 cm. Of the listed types, the first three are suitable for an apartment - with a wire thickness of up to 1.5 mm and a rectangular mesh with a side of 4-30 mm, but not all of them are equally effective.

The best characteristics are "cut" - made of a single sheet of metal and coated with zinc, therefore it is strong, durable and significantly increases the strength of the plaster layer with a minimum of waste during installation. But the listed advantages are also taken into account in its price - the material is more expensive than the two previous types of mesh in the list, and they also do a good job.

Welded meshes are made from steel bars and are used to significantly increase the strength characteristics. wall structures- in housing conditions, the need to use them is rare.

With a significant thickness of the plaster layer, the fastening of the metal mesh to the supporting base must be strong (like the base itself - concrete, brick, blocks), therefore, it is performed with self-tapping screws or dowels with home-made washers of large diameter, forming a gap between the reinforcement and the wall of at least 5 mm. Reinforcement of thick-layer plaster can be carried out in several layers - as the coating builds up.

But woven meshes made of galvanized wire or brass can also be used to reinforce thin-layer plaster - over insulation made of polystyrene foam or foam plastic, only it will cost more than using non-metallic reinforcement.

If large level differences on the wall are local, then there is no need to reinforce the base over the entire area, especially if a ready-made cement mixture is used for leveling. Where the thickness of the plaster is less than 2 cm, you can do without reinforcement - cut the mesh and nail it to the wall along the perimeter of the cut.

Polymer reinforcing meshes

The raw materials for the manufacture of these meshes are polyethylene, polyurethane, but most often polypropylene granules, which, after melting and mixing with optimizer additives, are extruded (punched) through a cellular shape of a certain profile. plastic nets are made with cells in the form of a square, rhombus or hexagon. The process of their manufacture is low-cost, so polymer mesh fabrics are widely affordable.

The technique of extrusion of polypropylene under high or, conversely, low pressure with the addition of additives makes it possible to obtain material of sufficient strength, uniform structure and fixed thickness. However, polypropylene meshes are inferior in strength to metal ones. Mesh sheets made of this polymer are most effectively used to prevent plaster cracking - they should not be reinforced with a plaster layer more than 2 cm thick. In addition, alkaline constituents cement-sand mixtures polypropylene is destroyed over time, so most meshes made of this polymer are more often used to reinforce gypsum coatings - but also not thicker than 2 cm. Polypropylene meshes are especially convenient for laying on foam, but it should be remembered that they are not attached to a heater, but to a freshly applied layer of the mixture , sinking into it with a roller, after which re-coating is performed.

Despite these disadvantages of polypropylene, the company "Astroplastica" (St. Petersburg) presents on the Russian market reinforcing meshes made of this material from the Italian concern "Tenax", which are declared to be chemically resistant:

1. "Plurima" - a cellular fabric made of strands strengthened by the technology of orientation, with knots at the corners of the cells (5x5, 5x6 or 6x6 mm), is used to reinforce thin-layer plaster and putty (5-1 mm);
2. "Armaflex" - a high-strength flat mesh fabric with a cell of 12x15 mm for reinforcing plasters 1-5 cm thick;
3. "Sintoflex" - 3 modifications marked E, M and D, high-strength mesh with cells 12x14, 17x24 and 22x35 mm.

The manufacturer managed to achieve the chemical resistance of polypropylene using special polymer additives.

Polyurethane meshes are produced in several modifications. Almost any leveling coating can be reinforced with them, therefore polyurethane meshes are also called universal.

Fine-mesh material (5x5, 6x6 mm) is intended for reinforcing external and internal plaster coatings made of ready mixes based on cement or gypsum with a thickness of 5 to 15 mm. Plastering homemade solution DSP on such a grid is not performed.

Grids with a cell of 13x15 mm (medium mesh) are designed for reinforcing facade and interior plasters up to 3 cm thick, made from ready-made or home-made compositions based on any binder (cement, lime, gypsum).

Coarse-mesh polyurethane meshes (22x35 mm) are designed for reinforcing plaster coatings of medium and large thickness, including large areas. Suitable for conventional solutions self-manufacturing and ready-made leveling compounds.

To reinforce the internal plaster, the polymer mesh with a cell size of 5x5 mm must have a density of at least 110 g/m2.

Fiberglass mesh for plaster reinforcement

Fiberglass filaments are produced by passing molten glass through micro-perforations. According to the place of application, meshes made of such fibers are divided into facade and interior ones. Both types have a mesh size of 5x5 mm, but the threads of the nets for outdoor work have a higher density (160 g / m2), which causes their high tensile strength, and are impregnated special composition increasing frost resistance.

With wide affordability, high flexibility and equal specific gravity, fiberglass meshes have the following advantages over polymer canvases:

1. Absolute chemical inertness;
2. Higher tensile strength;
3. Virtually unlimited operating temperature range (melting point 1500°C).

When choosing a fiberglass mesh for plaster, you should be guided by its specific gravity. The facade is reinforced with a material with a density of 90 g / m2, internal surfaces - from 60 g / m2.

On sale there is a fiberglass mesh with a cell of 10x10 mm with a density of 450 g / m2, used to reinforce thick-layer plaster coatings over large areas, but in an apartment, the outstanding characteristics of such a material will remain unclaimed.

Conclusion

Choosing a mesh for reinforcing plaster is not difficult. You only need to know the place of application, the maximum thickness of the future plaster coating and the leveling material.

As for the prices for reinforcing material, in Moscow and the Moscow region they are approximately the same.

Mesh for plastering interior walls allows you to finish the premises more efficiently. This technology prevents the solution from peeling off the surface, makes the coating harder and doubles its service life.

Plaster on the grid - what is it and why is it needed?

Plaster on the grid is one of the ways to finish the walls. This method is needed to strengthen the facing layer on uneven surfaces. Basically, it is used for exterior surfaces of civil buildings and industrial facilities. This is especially true for new, still draft houses. But sometimes rooms are treated in this way. In this case, it is necessary to distinguish between types of reinforcing material for external and internal work.

The cellular material may be fiberglass, polymer or metal. It all depends on where it is applied. To grids under internal plaster present their requirements. Such material must be alkali resistant. For this reason, it is impregnated with a special solution. If this is not done, then over time, cracks will appear on the lining. This means that the base has decomposed, and the plaster layer has lost its strength.

In addition to impregnation, the mesh for plastering interior walls must maintain strength and elasticity. According to SNiP, its density should correspond to the parameters of 150-170 g / m2. This will enable it to withstand the mechanical, wind and other loads experienced by the building as a whole. Usually, to protect the walls of the first floor by builders when performing plastering works metal mesh is used.

What is the mesh for plastering interior walls

Plaster layer on concrete, brick and wooden facades cracking and flaking. To avoid this, the walls are reinforced with mesh. There are 4 types of metal meshes:

• Woven mesh is a flexible and incredibly durable material. According to its structure, it consists of a woven wire of different sections. Ideal for DIY wall decoration. Has squares of cells 1x1 cm with zinc coating. Sold in building stores in rolls.
• chain link or woven mesh suitable for strengthening multi-layer plaster. Cell size 2 cm.
• A welded mesh with square cells is made by spot welding intersecting wires perpendicular to each other. Low-carbon, polymer-coated or galvanized steel wire is used for production. It is intended to prevent cracking of the finishing layer during the period of active wall settlement. To prevent cracks in the plaster, a mesh with 2/3 cm cells is used. It is sold in rolls 1 meter wide.
• Expanded mesh is produced by pressing from sheet metal. First, holes are cut through, and then the sheet is stretched to obtain diamond-shaped cells arranged in a checkerboard pattern. Apply under a small layer of solution. Rolls can be of different lengths, but standard width at 1 meter.

Under a very thin layer, a polymer mesh or fiberglass element is used, most often when needed or, as it is also called, "Venetian". This type of material has increased resistance to various kinds of chemical influences and does not spoil the final coating with spots during operation. Methods for attaching such nets can be different. If the wall is concrete or brick, then you can apply a little mortar on it and press the reinforcing material into it. On wooden or porous surfaces, you can fix the network with a stapler.

Preparation and start of finishing works

Before you start decorating the walls, you need to prepare everything you need: tools, remove debris, think and decide which type of mesh is best to use.

Important: a metal mesh is best suited for applying a mortar with a thickness of 3 cm or more. The chain-link is used when reinforcing walls that have not previously been plastered.

So, after you have prepared everything, you can proceed to the five steps.

1. Measure the height from floor to ceiling. Spread the mesh and use scissors for metal to cut the required number of panels.
2. Straighten and attach the mesh to the primed surface with nails or screws. At the same time, do not forget that the canvases should overlap with a width of 10 cm.
3. Get ready. Add an antiseptic to it so that there is no mold on the plaster in the future.
4. Throw a preliminary layer of mortar with a trowel, then level it with a rule. Let the fresh plaster set, then apply a leveling coat. Because it is thinner, it should be smeared directly with a trowel. To do this, take a small amount of the mixture for work surface tool and, pressing it against the wall, pull it from the bottom up. If the grid is visible, then repeat the procedure.
5. Let it dry, then cover the bumps with a spatula and rub these places with a grater. After curing, fine-tune the irregularities with fine sandpaper or a sponge moistened with water.

When plastering with polymer types meshes, apply the solution from the middle to the edges of the canvas, as if you are sticking wallpaper and expelling air from under them. Networks from polymer materials elastic and stretchy. When working with them, you need to be careful and make sure that bubbles do not appear on them. Now, depending on what the plaster was done for, you can either paint it or do it. decorative cladding.

Stucco cladding

Wall painting was the most widespread. Before proceeding with this type of cladding, you need to evaluate the quality of the surface: remove all cracks, make sure that the plaster layer is strong and does not lag behind the wall surface. After the putty has dried, it is necessary to treat the plane before painting with an aqueous primer.

Be careful with the choice of paint, which are going to paint the plaster.

Remember: fresh plaster, as a rule, has an excess of alkali, therefore it is highly undesirable to use compounds containing solvents. Please note that the plaster must be protected with a synthetic primer before applying organic solvent paints.

For painting walls, it is best to use a roller. It is necessary to process the surface carefully, do not leave gaps, and after the coating has dried, it should be painted over again. Acrylic, alkyd and latex compounds are best suited for painting facades.

No less popular way of finishing interior spaces wallpaper. In order for them not to peel off, you need to properly prepare the plastered surface. Remove all old wallpaper material from the walls and make sure the plaster is holding up well. Then the cleaned surface should be washed with water and inspected for cracks. If you find them, then they will need to be puttied and allowed to dry. Then treat such places with fine-grained sandpaper.

Choice wallpaper glue depends on the type of wallpaper and the surface on which you are going to stick it. Usually on the rolls there is an instruction with recommendations on which glue is best to use. In general, the technique for pasting plastered walls is not much different from the technique for other surfaces.

Out of ignorance of how to do this or that type of repair, you can not only spend a lot of time and effort, but also ruin expensive materials. We hope that the tips given in the article will help you to carry out repairs correctly and avoid many mistakes.

Hello dear friends! Today we will consider a very important component of facade decoration - a grid for wall plastering. When insulating a house heat-insulating material with subsequent plastering, the reinforcement process cannot be dispensed with.

For this, a special material is used - a reinforcing mesh for wall plastering.

What is its purpose, is it possible to do without construction mesh for plastering when performing separate " wet facade”, what types are offered today in the building materials markets and how to make a choice? We'll tell you below.

Properties:

• moisture resistance, resistance to temperature changes;
• low extensibility and deformation;
• high tensile strength;
• short specific gravity, does not weigh down the structure;
• resistance to aggressive environments.

All these properties help to significantly improve the quality of thermal insulation, as well as significantly extend the service life of thermal insulation and decorative layer. But all this cannot be done without first reinforcing the wall.

Fiberglass mesh - made of fiberglass, it is often used as a reinforcing mesh for plaster walls. Depending on the purpose, they are classified into:

• conventional, used for the base layer of plaster;
• reinforced, used to reinforce special structures, for example, when insulating the foundation, ground floors etc.;
• architectural, applied to specific elements of architecture.

Metal mesh for plastering or galvanized mesh - this mesh has a long service life and can be used in finishing any facades. For example, metal meshes for plastering can be used when finishing the facade with tiles (it is heavy and a powerful reinforcing layer is needed) or a plinth, when finishing with stone.

And also when choosing a facade mesh for plastering, be sure to take into account its density. Since strength and other important physical characteristics- depends on its density:

• up to 90g/m2 – for interior decoration and painting works;

• from 90 to 220 g/m2 - to strengthen the facade plaster, we recommend using this mesh in thermal insulation works;

• more than 220g/m2 - to strengthen elements of buildings subjected to maximum load or located in the ground.

What does the color say?

Today in building stores you can find fiberglass mesh for reinforcement different colors. There are five base colors: white, blue, green, orange, yellow.

Why are they available in different colors? This is done by manufacturers so that visually the meshes of different densities and with different cell sizes differ from each other, and the buyer can easily determine which mesh for plastering he needs and which mesh to choose.

For example, one well-known manufacturer orange fiberglass mesh has a density of 150 g/m2 and a mesh size of 5x5 mm, white - 45 g/m2 and 2x2 mm, respectively. Today, when choosing, I would not focus only on color. this product. Below we will describe the selection steps, by reading this you will be more prepared and easily cope with the selection task.

Choosing a mesh

When choosing a material for reinforcement when installing thermal insulation, you should pay attention to the following indicators:

1. Density, it should be from 145 to 160 g / m2, optimal size 5x5 mm.
2. Weaving quality and durability. To do this, just take a small piece and crumple. A good mesh should not tear, deform, and quickly return to its original shape.
3. Resistance to aggressive environments. The material must be treated with special alkali-resistant compounds.
4. Price. The cost of reinforcing material general rule should not exceed more than 5% of the total cost of insulation.
5. Safety. Feel free to ask the seller for a certificate of hygienic safety.

Fiberglass mesh for the facade is available in rolls of various sizes (usually 20 meters or 50 meters). The roll must be even and dense, it must have a label indicating the manufacturer and the characteristics of the material.

How to choose the right grid?

At experienced builders there are rules for choosing a grid, and we will tell you about them. Be sure to check it for tensile strength. Take a piece of mesh in your hand and squeeze it, if it is of high quality, then it should return to its original shape - it will straighten out.

Firstly, you need to decide why you need it, what you will do: plaster, tile, what is the thickness of the planned plaster, etc. Let's look at the choice with an example:

1. If the layer of our plaster (finish) does not exceed 5 mm, then it is recommended to use fiberglass mesh for reinforcement. Almost forgot to say reinforced mesh for plaster evens out the wall we are working on a little more. It is clear that it does not even out large differences, but it smooths out very well.
2. Now consider the case when the layer of plaster is more than 5 mm, then it is necessary to use a galvanized metal mesh, it will make the layer very strong. But be careful, we are talking about galvanized, not steel mesh. In no case should steel be used for facade decoration, as it oxidizes (rusts) and can ruin everything for you.
3. If you are already finishing the finish and you have a final, thin layer left, then you can use a canvas with very small cells.
4. If work is underway on a drywall surface, then a plastic grate is also suitable.

Conclusion

Since the main purpose of the plaster mesh is to create a powerful reinforcing base for further fixing the entire array of plaster or another version of the exterior finish of the facade of the building on it, its choice must be taken seriously.

Imagine what will happen if you save on it and as a result everything will crack decorative plaster, which significantly exceeds the price of even the most expensive facade mesh. Or, will start falling off decorative tiles which is also not cheap. There is only one conclusion - in no case should you save on the facade grid.
