What is needed for a plaster grid. Plaster facade on the grid: Tips from specialists

Plaster One of the most famous types of wall finish. In order for the solution to hold long and ensure strength, it must be reinforced using a special grid. In this article, we will consider the types of reinforcing grids in detail and tell you how to install them correctly.

Types of plaster grids

Grids for plaster walls can be made of metal or polyurethane. The wall is glued with glue, screws or screws. The canvas are sold in special rolls and has different dimensions, depending on the area of \u200b\u200bthe wall, which is placed.

Types of plaster grids for plastering walls a huge amount. Let's consider the main of them:

How to apply plaster

Depending on the method of applying plaster reinforcing grid can be fixed different ways. The first plaster layer is reinforced on top of the mixture, while it needs to be slightly pressed into the wall.

Tip! We recommend that the grid is secured before applying the last layer using special fixtures. If the area of \u200b\u200bthe workpiece is not too big as a fastener, the solution can be used. To do this, apply the mixture in the mounting places, you do not need to process the whole wall.

What better to choose

When choosing a reinforcing material for walls, the first thing to estimate the thickness of the future layer of plaster. You need to choose from the following options:

Plastic option

Purchasing it for the wall, remember that the density should be more than 110 grams per square meter and alkaline. The minimum layer thickness is 3 mm, and the maximum one-time. Before proceeding to work, rolls need to be trimmed according to the wall area. They depend on the selected method of placement - along or across. If there are defects on the wall, the material is better to arrange along the sutures of the solution. Make sure that the entire surface area is covered. Conduct the result is better with a reserve of ten centimeters to further strengthen the seams.

Plastic Mesh Fastening Technique

First of all, you will need to apply the first layer of plaster on the wall. Next, the plastic grid is already superimposed, and it is necessary to press it as stronger. Then the second layer of plaster is applied. It is not necessary to wait for drying, it is possible to stucify immediately. Plastic mesh should be placed in the middle of the wall. It can also be used for finishing the outer walls.

Most often, for fastening on the wall, we use screws or brackets and then carry out the processing. But this method is suitable only for the subtle layer of plaster. At the same time, the grid will be located exactly in the middle. If the thickness is more than 10 mm, then you should apply on the caps of pre-installed beacons. At the same time, the adjacent web needs to be placed in an adhesive in 10 mm. And only after that it will be possible to continue the plastering of the wall surface.

Working with a plastic grid, the stucco must be applied evenly. At the same time, to start better from the middle of the wall, distributing the mixture in different directions. Corners Recommended to press the rule or wide spatula.

Work with metal design

This option is used if plastering is planned more than 30 mm. The material is distinguished by its low weight, light installation and, despite the metal base, quite good protection against rust. But, unfortunately, for external work, the installation of such a canvase is not suitable.

First thing metal grid It will take to degrease. To do this, it can be washed with water or just lose a damp cloth. The installation process consists of the following steps:

It will be necessary to apply the solution twice, and it will be possible to continue only after complete drying of the first stage of plaster. It is applied using a trowel, the plaster is pressed into the grid so that the mixture reached the wall. Next, it is distributed throughout the wall plane with a spatula.

Plaster grid Rabita

Rabita grid, or as it is also called a braid, has a design with cell diameter of two centimeters. This canvas mainly use for the reinforcement of large areas or facades at home. At the same time, the Rabita is perfect for external work, at the expense of its materials it is well protected from weather influences. Method of installation on the walls is no different from metal Installation. It is light enough, so even the newcomer will be able to cope with such work.

Output

As you can see, the reinforcing mesh has a positive effect on the strengthening of the wall surface. It will protect the plaster from a possible detachment. This material can be used for both internal and external work. Montage itself does not take much time and strength, because the process is quite light. The main thing follows the instructions given in the article, and the result will not make yourself wait. We recommend View Tutorial Video:

The grid for plaster is the pledge of the durability of the work performed. Wall plastered - traditional alignment and finishing technology. And not only - still plaster is performed for the purposes of flame retardants and sound insulation, during repair, as a decorative finishing layer or as preparation under finish finish... But most often you need plaster plaster, cement - sandy and lime, it is like a finish. The use of mesh for plaster is an important condition.

The reinforcement of products from cement - sand solutions is a condition for their long exploitation, and a plaster layer is not an exception. In order for the layer of plaster to be durable and served for a long time, it is reinforced by placing inside the grid of plastic, fiberglass, steel, species and mesh materials are a lot. And you need to choose the grid on the basis of certain conditions.

Sharing plaster grid

Although technology and simple - approximately in the middle of the layer of the solution you need to put the grid, but some nuances are available. Two factors are important - the thickness of the plaster layer and the surface material on which it is applied. Self complex cases - This is a thick layer of plaster - more than two centimeters, and the surface of the finishing, not distinguished by good adhesion to cement - sandy solutions, that is, metals, wood, some types of panels. If one of these factors is present or both, it is important not only to ensure the adhesion of plaster with the wall, the reinforcing grid must also be firmly fixed. It is not enough to simply lay in the plastering layer - the result of such a work can be a durable layer of plaster, which lagged from the wall with a single layer.

Fasteners for plaster grid

Types of fastenings for grids are also dependent on the material of the walls - to concrete and brick, although they have good adhesions, the grids are fixed with dowels, using large washers, to wooden walls - Sometimes nails, but it is better to fix on self-drawing. If you need to plaster a metal surface - choose one of the types of steel grids, and then fixed with welding. The thicker requires a layer of the applied solution, the more powerful the grid is needed, sometimes we use a challenge. It is clear that thin woven metal grids are not suitable.

Cheap and common meshes made of fiberglass and polypropylene are used for plasters that do not differ in extreme. The thickness of the applied layer 15-20 mm plus the surface material, which is combined with plaster solutions - and can be performed without fasteners.

Preparation of the surface for plaster

Preparation of the surface under the stucco is very important. It doesn't matter whether the layer is reinforced or not - cleaning, dedusting, removing all old peeling finishes, as well as processing penetrating primers or primers - required condition. Properly prepared surface with good adhesion, a flat wall that does not require a thick layer for alignment - if all these conditions are made, the thin, durable and elastic mesh should be simply properly placed in the body of the plaster layer. At first, a layer of solution is applied to the wall of about 5 mm, then the grid is pressed into it with a wide spatula. The grid with a small cell is kept in the solution perfectly. Then this first layer should dry, grab. And the latter, the finishing layer, made by the same composition of the plaster - finally aligns the surface.

Brief overview of plaster grids

Plaster grids are very much, and all new, from a variety of materials appear. The time went when there was one way to strengthen the plaster on the wall and the ceiling - a wooden drank. Still happened, nails stuffed and tightened the wire on them. But modern spontaneous and woven steel grids, with galvanized and without, undoubtedly, stronger and more technological.

Plastic plaster grids

Apply not only for plaster, but also for brick and block masonry with the same purpose - reinforcement. The strength of the grids fully provides a laying of amplification - grids have high tensile strength. Material - polymers, cell usually 5 * 5 mm, release form - rolls. Technological, light by weight, and easily cuts, but it is very durable. Suitable for plastering layers with a small thickness - up to 20 mm.

Polyurethane mesh plastering with fine cell

Universal, suitable for walls, and for ceilings, for reinforcement of thin layers from solutions of any composition. Cell up to 6 * 6 mm. Mesh with a cell to 15 * 15 mm are considered average.

Large polyurethane plaster grids

Apply for the mechanized finishing of large areas - warehouses, hangars, facades of public and industrial buildings, etc. Cell 20 * 20mm, 30 * 30 mm, 35 * 35 mm, a mesh is produced in rolls.

Fiberglass plaster grid

For strength has best characteristicsthan plastic grids, withstands significant discontinuous efforts. Another advantage that many types of plastics do not possess - glass fiber is absolutely inert chemically, and its temperature range is practically unlimited.

Classification of fiberglass plaster grids

Fiberglass meshs are divided into density groups - the higher the density in g / cm2, the stronger the reinforced layer.

For inner plaster, paint and plastering fasteners are used. The name painted speaks for itself - this kind of grid is the easiest and thin, density of approximately 45-55 g / cm2. Cell small - 2 * 2 mm, 3 * 3 mm. Plaster grids for interior decoration have a density higher - up to 180 g / cm2 and cell from 4 * 4 mm, 5 * 5 mm.

Fiberglass for outdoor decoration and facades. Density from 180 to 220 g / cm2, cells 5 * 5 mm - 10 * 10 mm.

Fiberglass for plaster on the basement

By the very base, it is used for its part falling asleep. As well as for plastering underground structures and elements. Very durable and dense grids, for extreme conditions of work and large loads, are anti-vandal building materials. The price is much higher than on thin grids. Density up to 300 g / m2, and this is not the limit. In the marking of grids indicate the density and tensile tensile strength, as well as the purpose of the grid.

Fiberglass feature is a weak alkaline resistance. The main building finishing solutions are alkaline - they are classified as weak and middle alkali. Therefore, all the fasteners pass special processing - impregnation with polyacryl dispersions. Result - protection for a long time. Unprotected fiberglass cement mortar It is able to dissolve, "eat" for a period of from about several months to several years.

The fiberglass are produced in both rolls and ribbons with different widths. It is possible to buy their canvas usually a meter width, and even with finished fasteners from the corners - for reinforcing horizontal and vertical angles. Ribbons are used to finish cladding from GLC and GWL, and for other surfaces from panels, sheets or blocks, including foam and expanded polystyrene.

Fixtheres are used not only for plaster surfaces and strengthening the joints between walls and blocks of windows, doors, ventilation boxes, etc. In structural "pies" with heat and waterproofing, as well as to enhance the concrete screed and bulk sex, these grids have shown perfectly, and very popular.

Steel grids for plaster

Many types of metal wire meshes are produced. The sizes of cells are different, usually up to 50 mm. Steel grids are intended not only for reinforcing plaster layer, but also to strengthen the walls. Apply steel grids very wide - and indoors, and outside, for reinforcing and decorating surfaces from reinforced concrete and light concrete, bricks and stone.

Metal woven plaster grids

It is performed by a weaving method from a wire like a tissue of threads - sanzhev and linen. Cells are small, from 2 * 2 mm to 15 * 15 mm, production - meter rolls or 1.5-meter width. Wire applies galvanized and stainless, less often black.

By strength, woven metal meshs divide - light, medium sludge heavy, depending on the thickness of the wire used. The main diameters of the wire - from 0.32 mm to 0.8 mm, less often 1 and 1.2 mm.

Rabitz

Galvanized, and with colored polymer coatings are also produced. Use not only in the structures of fences, partitions or screens. To strengthen the saman and clay walls under the stucco, the elastic chain chain with a high relief is indispensable. Cells hold large volumes of plaster, creating a monolith from the strengthening and finishing layers, and the chain itself is easily attached to the wall surface.

Welded metal grids for plaster

They produce black, galvanized and with polymer coatings. Apply not only for masonry, concrete tie Both foundations, as well as to enhance structures with a thick layer of thermal insulation and for finishing surfaces under loads.

It is possible to use both for walls of stone, brick and concrete, and for wooden surfaces, with a thick layer of plaster, uneven walls and for loaded surfaces. Welded grids have a huge range of applications, cells from 5 * 5 to 100 * 100 mm, other sizes are possible, the wire thickness is usually up to 3 mm. The release - depends on the thickness of steel, rolls or sheets.

Mesh with galvanizing and heat treatment

For plaster, a special type of plaster grid is available - with galvanized and heat treatment. Grids are designed to distribute and hold solutions on vertical surfaces without loss. Cells from 10 mm to 100 mm, many sizes of grids with rectangular cells. Release - rolls and sheets, depending on the diameters of the wire.

Sustainable - exhaust plaster grids

Produced both wicker and solid metal sheets 0.5 -1.0 mm with a thickness of the leaf with a thickness and leaf. Widely used, including under the plaster, along with welded grids and chain grid. Perform the tasks of the holding and adhesion of the finishing layers, their hardening and significantly enhance the resistance to cracking during the shrinkages of buildings.

If the owner of the new building decided to shock the facade of his house, it is better that it was plaster on the grid. This option, which is most suitable for buildings that can still give shrinkage, as well as if the walls turned out very uneven and the alignment is needed a thick layer of plaster.

Reinforcement The canvas will not allow the layer of plaster to fall behind the wall and crack, but this is if the plastering process is performed correctly.

Masters repair work When plastering the walls of the facade use fiberglass or metal reinforcing grids. Fiberglass (polymeric) networks are used in cases when the applied layer of plastering is small, and the surface is quite smooth.

They are made of glass filaments. Depending on how thick the thread and use such webs in different fields:

• for painting work and indoor finishes It is customary to use fiberglass density up to 90 g per m2;
• for decoration of concrete, aerated concrete, seven or installation of thermal insulation - 90-220 g per m2;
• for the reinforcement of the foundation or other parts of the building in the ground, the fiberglass network with a density is higher than 220 g per m2 is used.

As for metal representatives, they are used to apply plaster with more than 2 cm thick. Among them there are also varieties:

1. The tannaya - is made of galvanized thin wire with the method of weave. Flexible enough, but durable. Building stores are sold in rolls. The repair masters for applying plaster with their own hands recommend buying such a grid with a cell size of 1 * 1 cm. Can be used to finish external and inland walls.
2. Braided, also called such a chain net. It is customary to use in cases where you need to apply a decent layer of plaster on a large wall area. The size of the cells used for such finishing work, 2 * 2 cm, which slightly simplifies the process of applying the solution.
3. Welded - made from galvanized or plated steel wire, method of welding rods in cross-country places. Square cells, their size from 2 to 3 cm. Apply on those buildings that can give the maximum shrinkage. This method of reinforcement fully protects plaster from slipping and cracking.
4. Sustainable - exhaust - manufacturers make such a grid of a solid metal sheet, cutting into a press of small diamond-shaped cells in a checkerboard and slightly stretched canvas. It is customary to use this kind of reinforcement where it is necessary to apply a small but neat layer of plaster.

Preparation

Before you start work, you must prepare the surface. If the building is new, a layer of primer is applied to the wall, which will increase the level of adhesion, and then the plaster will firmly hold on the basis.

If the building was built a long time ago, you first need to remove the old finish, clean it well, you can even wash the surface of the walls. In cases where traces of mold or mushrooms were found, these places need to be specially treated with antifungal composition so that the stains did not appear on the new coating. And only after that you can apply primer.

Mounting mesh

Working with the grid does not require special skills, but in order for the result to please need to adhere to the sequence in work. Let's start with the montage rules of the metal canvase:

1. Measure the height and width of the wall and cut into a canvas to certain pieces. For this, you will need scissors for metal or Bulgarian. You need to choose the device, respectively, the thickness of the rods. It is advisable to degrease a canvas with a solvent.
2. Start the mounting of the reinforced grid is needed from the ceiling. The upper edge is screwed with self-tapping screws along the entire length. Under the hats should be put a small piece of mounting ribbon or a wide washer.
3. If the basis is concrete or brick, then it is pre-drilled by a hole for a plastic dowel.
4. Between the mounts, the distance should not exceed 50 cm.
5. At the location of fixation, the grid touches the base, but in the intervals between the mounting the canvas should not contact the basis, it will worsen the properties of the plastering layer.
6. The reinforcing mesh in the joints of the joints is a mustache up to 10 cm.
7. The canvas need to tighten well so that there are no emptiness under the trim.

For fastening the fiberglass mesh, a completely different technology is used. This material is fixed only around the perimeter, starting from the upper side. Other mounts are not used as everything is fixed in the thickness of the applied plaster. And also need to be done on the hill in the joints of the joints up to 10-15 cm.

Rules for applying plaster

The plaster of the facade on the metal grid can be carried out with the help of lighthouses. (How to install beacons, described in the article, which is called "How to hold plaster walls for lighthouses without problems"). This will make it possible to make a smoother and smooth surface.

The entire plastering process takes place in several stages:

1. The cooked starter solution, which for consistency resembles sour cream, is applied to the wall using a trowel or bucket. You can spray or smear. The first option is much faster. After that, the layer needs to be dissolved by a spatula. The first layer must completely dry.
2. The second consistency solution is more dense than the first. They apply it to a trowel on a small surface of the wall and smash the rule, moving upwards. This layer must fully hide the grid. You need to give time to completely dry and this layer.
3. The third stage is performed if the surface turned out to be not smooth after the previous two stages. To do this, it is necessary to prepare a sufficiently liquid solution, and making circular movements on the wall. After complete drying of the last layer, you can paint the surface or lining.

If polymer is used for plaster walls, then here is their own features. The solution is first to apply the solution, then the grid is fixed using a stapler. At the same time, they begin to apply the mesh on the solution from the middle, carefully squeezing air bubbles as when the wallpaper is sticking, since the material is very thin and flexible.

Possible mistakes

Often, when performing work in a hurry or failure of the instructions arise errors that are very spoiled appearance. These include:

1. When using color plaster, the staining unevenness can manifest. This occurs when the applied layer is uneven in thickness, and accordingly he dries unevenly.
2. When the preparatory work was incorrectly, the plaster can fall off in large pieces.
3. In cases where the applied layer is too thin can be visible irregularities.

In order to avoid mistakes, do everything according to the rules, but better use the services of specialists.

The grid for plastering of the inner wall allows you to perform the finishing of the premises better. Such a technology prevents the separation of the solution from the surface, makes the coating more solid and increases its operating time by two times.

Stuccoing on the grid - what is it and why you need?

Stucco on the grid is one of the ways of finishing the walls. Such a method is needed to enhance the facing layer on uneven surfaces. Basically, it is used for the external surfaces of civil buildings and industrial structures. This is especially true for new, still giving houses. But sometimes the premises are treated in this way. At the same time, the types of reinforcing material for external and internal works should be distinguished.

The cellular material may be fiberglass, polymer or metallic. It all depends on where it is applied. To nets under inner plaster Presented their requirements. Such a material must have a resistance to alkaline effects. For this reason, it is impregnated with a special solution. If this is not done, then cracks will appear on the facing. This means that the basis has decomposed, and the plaster layer lost its strength.

In addition to the impregnation, the grid for plastering inner walls is obliged to maintain strength and elasticity. According to SNiP, its density must correspond to the parameters 150-170 g / m2. This will give her the opportunity to withstand mechanical, wind and other loads, tested by the building as a whole. Usually, a metal mesh is used to protect the walls of the first floor of the first floor when performing plaster works.

What is the mesh for plastering inland walls

The plaster layer on concrete, brick and wooden facades is cracking and peeling. In order to avoid this wall, reinforced with a grid. There are 4 types of metal grids:

• Grid woven - flexible and incredibly durable material. By its structure consists of a woven wire of different sections. Ideal for finishing walls with your own hands. It has 1 × 1 cm squares with zinc coating. Sold in construction stores rolls.
• Rabita or wicker grid is suitable for strengthening multilayer plaster. Size cells 2 cm.
• The welded mesh with square cells is made by point welding of intersecting wires located perpendicular to each other. The production comes low carbon, polymer coated or galvanized steel wire. It is intended to prevent cracking of the finishing layer during the actively precipitation of the walls. For the prevention of cracks in the plaster, a mesh with 2/3 cm cells is used. For sale in rolls 1 meter width.
• A spacious-exhaust grid is made by pressing from sheet metal. First hole holes, and then stretch the sheet to obtain diamond-shaped cells located in a checker order. Apply under a small layer of solution. Rolls can be of different lengths, but a standard 1 meter width.

Under a completely thin layer, a polymer mesh or a fiberglass element is used, most often, when it is necessary or, as it is also called, "Venetian". This type of material has increased resistance to various kinds of chemical effects and does not spoil the final coating by stains during operation. Methods for fastening such grids may be different. If the wall is concrete or brick, then it is possible to apply a little solution on it and put the reinforcing material into it. On wooden or porous surfaces, the network can be fixed using a stapler.

Preparation and start of finishing

Before proceeding with the walls of the walls, you need to cook everything you need: tools, remove the garbage, think and decide which kind of mesh is best used.

IMPORTANT: Metal mesh is best suited for applying a solution with a thickness of 3 cm. The chapter is used in reinforcing previously not subjected to plaster walls.

So, after you have prepared everything, you can start performing five steps.

1. Measure the height from the floor to the ceiling. Displays the mesh and with the help of scissors for metal, cut the required number of cloths.
2. Scatter and attach to the printed surface with nails or screws the grid. At the same time, do not forget that the canvas must go with a width of 10 cm.
3. Prepare. Add an antiseptic to it so that there are no mold on the plaster.
4. Press the preliminary layer of the solution to the craftsman, then crumple it with the rule. Give fresh plaster to grab, then apply an aligning layer. Because it is more subtle, it should be squeezed directly with Hacker. To do this, take a small amount of mixture to the working surface of the tool and, pressing it to the wall, stretch upwards. If the grid is visible, then repeat the procedure.
5. Let me dry, then whatever the irregularities with the spatula and set these places to the gravity. After hardening, perform a finite editing of irregularities with a shallow eye or moistened with water with a sponge.

When plastering with the use of polymer types of grids, a solution from the middle to the edges of the canvas should be applied, as if you stick the wallpaper and drive air from under them. The networks of polymeric materials are elastic and stretch. When working with them, it is necessary to observe accuracy and ensure that bubbles do not occur. Now, depending on what plaster was performed, you can or paint it, or do decorative cladding.

Facing plaster

The greatest distribution was painting walls. Before you begin to perform this type of cladding, you need to evaluate the quality of the surface: remove all cracks, make sure that the layer of plaster is durable and does not lag behind the wall surface. After putty dry, it is necessary to process the plane in front of the painting water primer.

Carefully treat the choice of paint, which is going to paint plaster.

Remember: Fresh plaster, as a rule, has an abrasiveness of alkali, therefore it is extremely undesirable to use compositions containing solvents. Consider that the plaster must be protected by synthetic primer before applying organic soluble paints.

For staining walls, it is best to use a roller. Processing the surface must be carefully, not to leave spaces and after drying the coating should be punished again. For painting facades, acrylic, alkyd and latex formulations are best suited.

No less popular finish interior premises Wallpaper. In order for they do not dug, you need to properly prepare an plastered surface. Remove the entire old wallpaper material from the walls and make sure that the plaster holds well. Then the purified surface should be washed with water and inspect whether there are no cracks. If you find them, they will need to sharpen and give time to dry. After that, process such places with a fine-grained skin.

The choice of wallpaper glue depends on the type of wallpaper and the surface on which you are going to stick them. Usually on rolls there are instructions with recommendations, which glue is best to use. In general, the technique of pasting plates of plastered walls is not much different from the equipment for other surfaces.

By ignorance, how to do one or another type of repair, you can not only spend a lot of strength and time, but also to spoil expensive materials. We hope that the data in the article advice will help you correctly repair and avoid many mistakes.

Alignment different surfaces Using ─ one of the in-demand methods for the preparation of walls and the ceiling to staining or pasting with wallpaper. However, plaster does not always fall smoothly, without defects. Some surfaces have low adhesion, so the solution applied to them begins to crumble and peel. Especially fast destruction of the defensive decorative layer manifests itself on the facades of buildings that are exposed. negative impact Climate and moisture. Using the grid for plastering walls, it is possible to provide a solid fixation of the solution with the surface and improve the quality of the finish.

Application

The grid is used for external and internal works, and helps to achieve the following results:

• Increase the durability of decorative finishes due to the correct distribution of the load and reduce its impact on 1 m2. The grid is fixed on the base, and with its help hold the weight of the solution.
• Avoid cracking plaster due to the reinforcement of the surface layer. Walls and partitions from blocks and bricks are prone to shrinkages and deformation. The reinforcing canvas gives the trim of plasticity and prevents the appearance of cracks and other defects on the surface.

Types of grid

For the manufacture of the grid use different materialswhich, along with other parameters, determine its appearance, characteristics and scope.

• Rabita. It is made of low carbon steel wire by weaving and is a web with cells of a square or rhombid shape and a size of 20 × 20 mm2. To protect against moisture and aggressive substances, the mesh is coated with a layer of zinc or polymer. Rabita is used to work on the surfaces of a large area, including wooden or brick.

• Welded. It is made from steel wire, which is superimposed at right angles on each other, and then fixed in the connecting places with point welding. As a result, a durable mesh is formed with square shape cells of different sizes. It is used to strengthen plaster with a strong shrinkage of walls, which is relevant for finishing new buildings or houses located in unstable soil.

• Non-exhaust. It is a sheet material with a diamond-shaped cells and is intended for reinforcing walls with a small consumption of plaster. The spots are made by cutting holes of the same shape and size on a sheet of metal, which is then stretched and converted to the mesh for plaster.

If it is necessary to apply a solution as a thin layer as a thin layer it is advisable to use a plastic mesh or fiberglass.

• Fiberglass. Indispensable for finishing ceilings, facades and walls if there are recesses, grooves and depression on their surface. It is characterized by slight weight, strength and resistance to temperature drops, and can be used for facades. Fiberglass grid is not susceptible to moisture, so it is used to reinforce the roof and coating of the bathrooms and pools.

• Polymer grid. It is produced by extrusion from polymer raw materials, which is most often used polypropylene. With the help of molding machines, the plastic melt is converted into a mesh cloth, the size of the cells of which is determined by the modification of the material. Plastic grid serves to carry out plastering on the surface of the facades and inner partitions. Since over time, the mixture of sand and cement is destroyed by a polymer cloth, it is advisable to use for decoration. The grid with cells 2 × 2 mm2 is indispensable for applying finishing putty.

Mesh laying technology

For finishing works, several types of plaster mixtures are used, which differ in composition, nuances of application and degree of impact on various materials. In addition, when choosing a grid should be considered:

• the thickness of the applied layer;
• base material;
• the conditions for performing finishing and operation of the coating.

Metal

When choosing a metal mesh for reinforcement, it is worth a galvanized preference: it prevents the appearance of corrosion and prevents the occurrence of rusty spots on the walls. In addition, it is easy to cut and just fix on the surface. Before working, the metal grid should be deguted, and galvanized ─ just rinse with water. The formation of the reinforcing layer is as follows:

1. With the help of scissors for metal, the grid is cut into separate web, the size of which depends on the orientation of the material on the surface. In the presence of the rust, the reinforcing layer for plaster is placed along each seam of a solid web.
2. Drill holes with a diameter of 6 mm using a perforator. Their depth should exceed the length of the dowel by 2-3 mm, and the step is 25-30 cm.
3. Insert the dowels into the resulting holes, and then fix the mesh on the surface of the walls using the mounting tape and screws. For reliable fixation of the canvas, there is a mustache, with an occasion of each other about 10 mm.
4. Install lighthouses, and push the first layer of plaster, using a trowel. In this case, the solution needs to be pulled in such a way that it passes through the reinforcing canvas and fixed on the surface. After that, the finish layer is evenly distributed over the surface of the wall or ceiling.
5. The second layer of plaster is applied when the first drying is dried. If the basis serves as a facade with insulation, then it is advisable to use to reinforce the chain surface. It is also necessary when finishing wooden walls.

Plastic

If necessary, protect the plaster from cracking use plastic grid. Especially in demand in cases of interior decoration, when the basis of the basis is possible. Algorithm actions such.
