Review and advice on choosing reinforcing nets for wall plastering. Facade reinforcing mesh Polymer mesh for facade plastering

The polymer mesh installation technique involves a number of stages.

1. At the first stage, the foundation is prepared. Preparatory work include cleaning and priming the surface.
2. The next step is to measure the wall surfaces and cut the canvas in accordance with the measurements taken and add a margin of about 10 cm (for overlapping canvases).
3. After this, the preparation of the glue-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 painting mesh into the solution.
5. After the initial layer has dried, the surface is covered with a primer and a final layer of plaster is applied, leveling is performed according to the rule.
6. At the last stage, the dried wall surfaces are sanded.

A few quick tips to help you get the most out of your wall plastering work.

1. The denser the plaster layer applied to the brick or concrete base, the stronger the steel mesh to be installed must be.
2. Simple steel mesh in rooms with high level humidity, for example in saunas and bathrooms, as well as for external cladding it is undesirable to apply. The thing is that steel types materials are prone to rust formation. It is preferable to install a mesh made of fiberglass or welded with a galvanized coating.
3. Before installing the metal reinforcing product, it must be degreased.
4. Reinforcing mesh made of plastic for cement-based plaster is unacceptable, since over time cement mix will corrode the product.
5. Many, when performing work on plastering walls, first lay the mesh to the wall surface and only after that they plaster - 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 for 1 sq. m. requires about 16-20 pcs.
7. When installing the reinforcing material, do not let it 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 use of a reinforcing mesh with cells with a diameter of 5x5 mm and 10x10 mm.
9. The fiberglass mesh should be impregnated with a polyacrylic compound. If the mesh does not have impregnation, it cannot be used with 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 mesh-netting.
11. With a layer density of about 50 mm, it is undesirable to perform plastering of walls due to strong surface differences. Preferably used for decoration Wall panels- this finishing material will help to hide existing defects.
12. In the case of plastering small areas, it can be used as fasteners plaster mix... It is applied pointwise, after which it is evenly distributed over the entire area.

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

Modern standards for interior and exterior surface finishes have very high demands on the aesthetics, durability and reliability of the finish. The mesh for plastering walls significantly improves the quality, which in general has a beneficial effect on the final result. And although the reinforcing layer is not visible, it is this layer that ensures the stability of the structure, preventing the plaster from cracking.

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

Reinforcing mesh for wall plastering - types and characteristics

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

• the selected mixture;
• the material of 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

The following types of reinforcing grilles can be distinguished, which are most in demand on 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 works. Medium, mesh 13 * 15 mm, for finishing up to 30 mm thick on not large areas... Large with a cell of 35 * 22 mm - a grid for facade plastering, it is reinforced with large areas under a thick layer of plaster: external walls of houses, warehouses, etc.

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

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

• Plurima is a polymer mesh for plaster, oriented on 2 axes, with a cell of 5 * 6 mm, lightweight, inert to chemical influences, used for indoor and outdoor work.
• The lattice is polypropylene armaflex, it is distinguished by reinforced nodes, the cell is 15x12 mm. Extra strong, used in areas where heavy loads are applied to the plaster.
• Syntoflex made of polypropylene, cell 14 * 12 mm or 35 * 22 mm, not afraid of impact chemical environment, lightweight, durable. Suitable for plaster interior walls and facades.
• Steel grating is made from metal rods of different cross section, soldered in nodes, cells from small to very large, tolerate mechanical loads well, but it should only be used for internal plaster, as it corrodes under the influence of atmospheric phenomena.
• Metal mesh for wall plastering, galvanized, made of rods different section, nodes are welded, the size of the cells is different. It is universal for outdoor and indoor use, it is not afraid of difficult operating conditions.
• Chain-link - metal mesh for plastering external and internal walls, under a thick layer, distinctive feature- braided cells, they are of 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 mainly used under a thin layer.

Expanded galvanized grating

Selection conditions

The grid for plastering the walls is needed so that as much as possible, and the solution does not peel off the surface, after drying, cracks do not go. It is a skeleton that provides strength and integrity to the structure.

If there are rusts on the walls, ceilings, facades - depressions, grooves, depressions, usually reaches 30 mm, in such works, fiberglass reinforcement is most often used, 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 useful when plastering very uneven surfaces and when used.

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

Welded grill for finishing brick surfaces

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

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

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 used, it is nailed between the joints of the masonry. V recent times In these works, a fiberglass sheet is often used, which is 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. Facade welded mesh for plastering - 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 leveling, the classic of which is plastering. The plaster coating is often reinforced with a mesh of various materials a certain mesh size. This additional stage complicates and increases the cost of the process, but under certain circumstances you cannot do without it.

Consider the role of reinforcement in plastering, and which reinforcement mesh to give preference to in this or that 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.

Plaster reinforcement 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 plastering 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. Provides the integrity of the plaster layer, preventing cracking or neutralizing its effects. The specific gravity of the plaster is significant, therefore, 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. Reinforcing mesh, even if the finish peels off, will prevent it from collapsing.
3. Increases the bearing capacity of the plaster. Peeling of the plaster coating in case of loss of adhesion to the base can cause the finish to collapse on the solid wall surface as well. This can be provoked by the load from the interior elements (shelves, cornices) mounted on thick-layer plaster 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 should be reinforced to avoid delamination.

The functionality of plaster contains the answer to the question 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 vibration effect on it;
3. In the presence of a factor of periodic uneven shrinkage of the building (redevelopment in 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 plaster was reinforced by laying it on shingles, which compensated for the lack of adhesion to the base and reduced the likelihood of the coating collapsing. But the installation of shingles is a time-consuming operation, and the mounted reinforcing grille, with its modest physical characteristics, was also vulnerable to moisture and microorganisms.

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

The main classification of reinforcing meshes - by material of manufacture:

• metal;
• polymer;
• 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, which, according to the manufacturing method, are of the following types:

1. Woven - from low carbon, galvanized or stainless steel, brass;
2. Mesh-chain-link - ordinary, galvanized or polymer-coated steel;
3. All-metal expanded mesh (CPVS, "notched") - from ordinary or galvanized steel;
4. Welded - plain or painted steel.

The meshes also differ in wire thickness and mesh size.

Metal mesh plaster stone walls reinforce with significant level changes - 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 have a "notch" - it is made of a solid 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 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 with the task.

Welded meshes are made from steel bars and are used to significantly improve 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 homemade large-diameter washers, forming a gap between the reinforcement and the wall of at least 5 mm. Reinforcement of thick-layer plaster can be performed in several layers as the coating grows.

But thin-layer plaster can also be reinforced with woven nets made of galvanized wire or brass - on top of insulation made of expanded polystyrene or expanded polystyrene, it will only cost more than using non-metallic reinforcement.

If large differences in level 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 mesh

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

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

Despite the indicated 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 chemically resistant:

1. "Plurima" - a cellular fabric made of threads strengthened by the orientation technology, with knots at the corners of the cells (5x5, 5x6 or 6x6 mm), 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 with a thickness of 1-5 cm;
3. "Syntoflex" - 3 modifications with markings E, M and D, high-strength mesh with cells 12x14, 17x24 and 22x35 mm.

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

Polyurethane mesh is available in several modifications. Almost any leveling coating can be reinforced with them, therefore polyurethane nets are also called universal.

Fine-mesh material (5x5, 6x6 mm) is intended for reinforcing external and internal plaster coatings from 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-cell) are intended 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 nets (22x35 mm) are intended for reinforcing plaster coatings of medium and large thickness, including in large areas. Suitable for conventional solutions self-made and ready-made leveling compounds.

For the reinforcement of 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

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

With wide availability in price, high flexibility and equal specific gravity, fiberglass meshes have the following advantages over polymer webs:

1. Absolute chemical inertness;
2. Higher tensile strength;
3. Practically 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, which is used to reinforce thick-layer plaster coatings on large areas, but in an apartment, the outstanding characteristics of such a material will remain unclaimed.

Conclusion

Choosing a mesh for plaster reinforcement is not difficult. You just 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.

The net for plastering of interior walls allows for better finishing of premises. 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?

Plastering on a grid is one of the ways to decorate walls. This method is needed to strengthen the facing layer by uneven surfaces... It is mainly used for exterior surfaces of civil buildings and industrial buildings... This is especially true for new houses that are still undergoing sediment. But sometimes premises are treated in this way. In this case, it is necessary to distinguish between the types of reinforcing material for external and internal work.

The cellular material can be fiberglass, polymer or metal. It all depends on where it is applied. To the grids under internal plaster have their own requirements. Such a material must be resistant to alkaline attack. For this reason, it is impregnated with a special solution. If this is not done, then over time, cracks will appear on the cladding. 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 retain strength and elasticity. According to SNiP, its density should correspond to the parameters of 150-170 g / m2. This will give it the ability to withstand mechanical, wind and other loads experienced by the building as a whole. Usually for the protection of the walls of the first floor by builders when performing plastering works metal mesh is used.

What is the mesh for plastering interior walls

Plastering layer on concrete, brick and wooden facades cracks and flakes. To avoid this, the walls are reinforced with mesh. There are 4 types of metal mesh:

• Woven mesh is a flexible and incredibly durable material. By its structure, it consists of woven wire of different cross-sections. Ideal for DIY wall decoration. Has a square of cells 1 × 1 cm with a zinc coating. Sold in rolls in hardware stores.
• Chain-link or braided mesh suitable for strengthening multi-layer plaster. The size of the cells is 2 cm.
• Welded square mesh 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 upsetting of the walls. To prevent cracks in the plaster, a mesh with 2/3 cm cells is used. It is sold in rolls 1 meter wide.
• Expanded metal mesh is produced by pressing from sheet metal... First, holes are cut, and then the sheet is stretched until diamond-shaped cells are staggered. Apply under a small layer of solution. Rolls can be of different lengths, but standard width 1 meter.

A polymer mesh or fiberglass element is used under a very thin layer, 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. The methods of attaching such nets can be different. If the wall is concrete or brick, then you can apply a little mortar to it and press the reinforcing material into it. On wooden or porous surfaces, you can fix the net with a stapler.

Preparation and start of finishing works

Before you start decorating the walls, you need to prepare everything you need: tools, remove trash, 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. The chain-link is used for reinforcing walls that have not been previously plastered.

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

1. Measure the height from floor to ceiling. Spread out the mesh and use metal scissors to cut the required number of panels.
2. Spread out and fasten 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. Prepare. Add an antiseptic to it so that there is no mold on the plaster in the future.
4. Apply a preliminary layer of mortar with a trowel, then level it with a rule. Let the fresh plaster set, then apply a leveling layer. Because it is more subtle, it should be smeared directly with a scraper. To do this, take a small amount of the mixture on work surface the tool and, pressing it against the wall, pull it up from the bottom. If the mesh is visible, repeat the procedure.
5. Let it dry, then cover the irregularities with a spatula and rub these places with a float. After hardening, finish the unevenness with a fine sandpaper or a sponge dampened with water.

When plastering using polymer species nets, the solution should be applied from the middle to the edges of the canvas, as if you were gluing wallpaper and expelling air from under them. Networks of polymer materials elastic and stretchable. 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 decorative cladding.

Plaster cladding

The most widespread was the painting of the walls. Before proceeding with this type of cladding, you need to assess 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 is dry, it is necessary to treat the surface before painting with an aqueous primer.

Carefully consider the choice of paint with which you are going to paint the plaster.

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

It is best to use a roller to paint the walls. The surface must be processed carefully, no gaps should be left, and after the coating has dried, it should be painted over again. Acrylic, alkyd and latex compounds are best suited for painting facades.

The finishing method is no less popular indoor 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 adheres well. Then the cleaned surface should be rinsed with water and inspected for cracks. If you find them, then they will need to be putty 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, the rolls have instructions on which glue is best to use. In general, the technique of pasting plastered walls is not much different from the technique for other surfaces.

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

Hello dear friends! Today we will consider a very important component of facade decoration - this is a grid for wall plastering. When insulating a house thermal insulation material with subsequent plastering, you cannot do without the reinforcement process.

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 markets of building materials and how to make a choice? We will tell you below.

Properties:

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

All these properties help to significantly improve the quality of thermal insulation, as well as significantly extend the life of the 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:

• usual, used for the base layer of plaster;
• reinforced, used for reinforcing special structures, for example, when insulating a foundation, basement floors etc.;
• architectural, used for specific elements of architecture.

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

And also when choosing a facade mesh for plaster, its density must be taken into account. Since strength and other important physical characteristics- depend on its density:

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

• from 90 to 220 g / m2 - to strengthen the plaster of facades, it is this mesh that we recommend to use in thermal insulation works;

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

What does the color say?

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

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

For example, one renowned 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, I would not be guided only by color when choosing of this product... Below we describe the stages of selection, after reading this you will be more prepared and easily cope with the task of selection.

Choosing a facade 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. Weave quality and strength. To do this, just take a small piece and crumple it up. 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 by general rule should not exceed more than 5% of the total cost of insulation.
5. Security. Do not hesitate to ask the seller for a hygiene certificate.

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

How to choose the right mesh?

Have experienced builders there are rules for choosing a net, and we will tell you about them. It is imperative to check it for tensile strength. Take a piece of the net in your hand and squeeze it, if it is of high quality, then it should return to its original shape - it should straighten.

First, you need to decide what you need it for, what you will do: plaster, lay the tiles, what is the thickness of the planned plaster, etc. Let's consider the choice by example:

1. If the layer of our plaster (finish) does not exceed 5 mm, then it is recommended to use fiberglass mesh for reinforcement. I almost forgot to say reinforced mesh for plaster, it evens out the wall we are working on a little more. It is clear that it cannot even out large drops, but it smooths out very well.
2. Now let's consider the case when the plaster layer 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 facades, 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, then you can use a canvas with very small cells.
4. If work is underway on a plasterboard surface, then a plastic grill will do.

Output

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

Imagine what will happen if you save on it and as a result everything is cracked decorative plaster, which is much more expensive than even the most expensive facade mesh. Or, will start to fall off decorative tiles which is also not cheap. There is only one conclusion - in no case should you save on the facade mesh.
