The plaster on the grid is an effective way of black wall decoration. The particular advantage of this method is that it is possible to apply a thick layer of the solution with it, which in the finish process will not slide and peel under its own weight. What is the procedure itself, what types of mesh use in certain cases, and how to fix them? About it - hereinafter.

When the walls are plastered without the use of the reinforcing layer, the risk that the applied solution will be simply falling off from the base. And when finishing the brick and wooden surfaces, the plaster can start peeling and crumble even after repairing the repair. This usually occurs due to insufficient adhesion indicated above materials. The grid allows you to form a monolithic plate, which are not terrible any loads. Different meshes are calculated on a certain load, and the type of material used depends on the thickness of the plaster layer.

On a note! With the help of reinforcement, a durable coating is created, which is not cracking in the process of long-term operation. Even with violation of the technology of preparing the solution, the grid will ensure the integrity of the plastering layer.

Types of grid

There are several types of products used for reinforcement, the main materials are the following materials:

• fiberglass;
• metal.

Types of reigning mesh: a - metal; B - fiberglass

When applying a thin layer of solution on a flat surface, usually fiberglass canvas are used. For finishing the curves of walls, when the thickness of the plaster is more than 2 centimeters, the product is suitable exclusively.

In turn, metal meshs also have several types:

• woven - durable and flexible material, which is made of a small cross section. Use such a product for both external and internal works. When choosing a woven canvase for reinforcement, it should be borne in mind that the optimal cell size in this case is 1x1 cm;
• wicker - she is a chain grid. It is best suited for finishing surfaces with a large area. The most common cell size is 2x2 cm;
• welded - made of wire with point welding. Located perpendicular to each other, the rods form square cells, the optimal value of which during reinforcement is 2-3 cm. Welded products are most often used for finishing structures subject to a strong shrinkage;
• non-exhaust - It is made from sheet metal by forming diamond cells on a special machine. Such material is usually mounted in cases where a small solution consumption is assumed to 1 m2.

How to fix a metal grid?

To work with a metal grid, you will need selflessness, construction dowels and a metal mounting tape.

1. Before mounting the canvas, it is necessary to cut off the desired piece, having previously measured the area to which the plaster will be applied. For cutting of a thin material, there will be no scissors for metal. If the product is made of wire with a diameter of 2 mm, you will need a Bulgarian. The cutting canvas need to be deguted, the rubbing of it with a rag moistened with a solvent.
2. Fastening the mesh under the stucco, you need to start from the ceiling. The top of the material is fixed along the entire length of self-pressing, under the hats of which are put on the sliced \u200b\u200bfragments of the mounting tape. You can also use wide washers as gaskets, but they are much more expensive than the tape.
3. When mounting on the surface of concrete or brick in the wall, you need to drill holes and insert plastic dowels in them.
4. The distance between self-pressing depends on the size of the cells and the thickness of the grid itself. But in any case, it is desirable that the fastener step is not more than 40-50 cm. In places of fixation, the canvas can come into contact with the wall, and in the intervals between the fasteners it should not be in contact with the surface, since in this case the quality of the plastering layer will deteriorate.
5. At the joints, the material is mounted with an adhesive of 8-10 cm.
6. Properly fixed canvas should be well stretched. If the material does not vibrate in the lack of fasteners, it means everything is in order. Otherwise, the formation of voids under the grid is possible, which will adversely affect the quality of the finish.

Installation of fiberglass cloth

In this case, the mounting to the wall of the plaster grid is performed by fixing the material only around the perimeter of the canvas. First, with the help of screws, the upper edge of the grid is fixed in several places, and then all other parties. Additional fasteners are usually not used, since in the further when applying the solution, the grid is securely fixed in the thickness of the plaster.

Fix the fiberglass mesh on the wall is possible with a solution of plaster, with the occurrence of difficulties, you can use screws

Since the grid is initially rolled into rolls, then for the convenience of installation it is better to unwind and mount the material along the walls, parallel to the floor. Starting the mount is needed on top, from any angle of the room. The jokes have an inquiry with 15-20 cm.

You should know! It is best to cut the material so that a solid canvas can be pulled. This will provide a higher strength of the plastering layer.

Preparation of the wall under the plaster and the installation of beacons

Even when using the mesh, the surface needs to be prepared:

• First of all, the wall is freed from the old finish (if any) - paints, plaster, etc.
• Next, dust is removed from the surface. If there is fungus and mold on the wall, the affected areas should be cleaned with a metal brush.
• After that, the surface is treated with primer, which makes it possible to improve the quality of the clutch, strengthen the base and prevent the formation of mold and corrosion.

After preparing the base and installation of the reinforcing canvas, it is necessary to help form a smooth surface in the fascination process. A special profile uses as beacons.

Installation is the following procedure:

1. Using the construction level, set an extreme profile in a strictly vertical position and fasten it with two screws.
2. Next, the lighthouse is fixed with a gypsum solution.
3. The next step is to install the lighthouse from the other edge of the wall. To mount all profiles in the same plane between the extreme guides, stretch the thread.
4. Then the other lighthouses are installed, the distance between which should be less than the length of the rule.

Flashing surface

After installing beacons, you can move to the plastering process. The plaster of walls on the grid is performed in several stages, each of which is applied one layer of solution.

First stage. Watching is usually performed in 2 or 3 layers, depending on the material of the walls. The initial layer is applied by "spray". For this, a solution is prepared, which must resemble sour cream on consistency. The finished mixture is thrown by a trowel or a bucket in an arbitrary order. The solution can be smeared, but the first option is easier and faster. The applied mixture is moving with a spatula. The thickness of the "spray" layer should be about 10 mm.

Second phase. After complete drying of the first layer, mix a more thick mixture of a tough consistency. The solution applied with the help with the help of the Rule, which is pressed to the beacons and stretch upwards. This layer must completely cover the reinforcing grid. After the solution is grabbed, the profiles are pulled out, and the remaining furrows close up.

Third stage. Final procedure - the final leveling of the frozen surface. To do this, they prepare a liquid solution and, applying it onto the wall, rub in circular motions with the help of Hacker.

The above-mentioned plastering technology is suitable for finishing any surfaces, regardless of which reinforcing mesh is used.

Hello dear friends! Today we will look at a very important component of the finishing of facades - this is a grid for plastering walls. When the house is insulation, the heat insulating material followed by plastering can not do without reinforcement process.

For this purpose, a special material is applied - the reinforcing grid for plastering walls.

What is its purpose, is it possible to do without a construction grid for plaster when performing a "wet facade" separated, which types are offered today in the construction materials markets and how to make a choice? Tell me below.

Properties:

• moisture resistance, resistance to temperature differences;
• low rates of extensibility and deformation;
• high tensile strength;
• low specific weight, does not waste design;
• resistance to aggressive media.

All these properties help significantly improve the quality of thermal insulation, as well as to significantly extend the life of the thermal insulation and the decorative layer. But all this is impossible to do, pre-reinforcing the wall.

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

• ordinary applications used for the base layer;
• reinforced used for the reinforcement of special designs, for example, when insulation of the foundation, ground floors, etc.;
• architectural used for special architectural elements.

Metal mesh for plaster or galvanized grid is a grid has a long service life and can be used in finishing any facades. For example, metal mesh metal can be used when finishing the facade with tiles (it is heavy and a powerful reinforcing layer is necessary) or base, when finished with a stone.

As well as choosing a facade mesh under the plaster, be sure to take into account its density. As the strength and other important physical characteristics - depend on its density:

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

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

• more than 220g / m2 - to enhance the elements of buildings that are maximum load or located in the soil.

What does the color say?

Today in construction stores you can meet the foxes for reinforcement of different colors. There are five basic colors: white, blue, green, orange, yellow.

Why are they producing different colors? This makes manufacturers to make visually grid different density and with different cell sizes differed among themselves, and the buyer could easily determine which mesh under the stucco it needs and what a grid to choose.

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

Choose a facade mesh

Choosing a material for reinforcement with thermal insulation device, it is worth paying attention to the following indicators:

1. Density, it must be from 145 to 160 g / m2, the optimal size is 5x5 mm.
2. The quality of weaving and strength. To do this, it is enough to take a small piece and squeeze. A good grid should not break, deform and quickly return the original shape.
3. Resistance to aggressive media. The material must be processed by special alkaline compositions.
4. Price. The cost of reinforcing material as a general rule should not exceed more than 5% of the entire cost of insulation.
5. Safety. Feel free to demand a certificate of hygienic security from the seller.

The fox for the facade is produced in rolls of various patterns (usually it is 20 meters or 50 meters). The roll must be smooth and dense, it must be a label indicating the manufacturer and characteristics of the material.

How to choose the right grid?

Experienced builders have their own rules on the selection of the grid, and we will tell you about them. It is necessary to check it on resistance to stretching. Take a piece of the grid in your hand and squeeze it if it is high-quality, it should return to your original shape - straighten.

First, it is necessary to decide why you need it, that you will do: plaster, put the tile, which thickness of the planned plaster, etc. Let's consider the choice on the example:

1. If the layer of our plaster (finishes) does not exceed 5 mm, it is recommended to use the glasswork for reinforcement. I almost forgot to say, the reinforced grid for the plaster still lines the wall on which we work. It is clear that the big differences are not to align it, but it smoothes very well.
2. Now consider the case when the layer of plaster is more than 5 mm, then it is necessary to apply a metal galvanized grid, it will make a layer very strong. But be careful, we are talking about galvanized, and not about the steel grid. It is impossible to apply the steel for finishing facades in any cases, as it is oxidized (rust) and everything can be spoiled.
3. If you are already completing the finish and you have the final, thin layer, then you can use a canvas with very small cells.
4. If there are work on the plasterboard surface, then the plastic grille is suitable.

Output

Since the main purpose of the plaster grid is the creation of a powerful reinforcing base for further fixation on it of the entire array of plaster or other option of the exterior finishing of the building of the building, refer to its choice it is necessary seriously.

Imagine what will happen if you save on it and as a result, all decorative plaster cracks, which is accurately superior to even the most expensive facade mesh. Or, the decorative tile will begin fall off, which is also not cheap. Conclusion Only one - on the facade grid, it is not necessary to save in any cases.

Repair, especially in secondary housing, is impossible without aligning all sorts of surfaces, be it walls, ceiling or floor. The most appropriate option for working on alignment is the use of plaster. This option provides not only alignment of the surface, but also heat and noise insulation in the apartment, which is often an important factor for tenants. For a more reliable and solid leveling layer, you must use a special plaster grid. It not only fixes the leveling layer, but also prevents cracking and peeling the material from surfaces.

Features

First of all, it should be noted that the plaster grid is a universal material, the use of which is possible at all levels of construction and finishing. For example, it can serve as the base of the wall panel, and can be used as a cross-layer layer when aligning surfaces. Purpose and efficiency in its use will be directly dependent on the material from which one or another type of grid is made, in addition, the design features of different types can be played.

Most often, the plaster grid is still used for outdoor work.It is a clutching layer between the wall and the leveling layer of plaster. The best grip occurs due to the structure of the cells, which are inherent in all mesh surfaces, it is due to them that there is a filling of empty spaces with a plaster mixture and its better adhesion with an aligned surface. And also precisely because of this property, the result is a smooth monolithic texture.

Another feature and, at the same time, the advantage of this material is the ease of its installation, so the alignment of the surface with plaster and grid is subject to even inexperienced to the master's repair work.

The solution is reliably grasped, not flowing, as a result, forms a reliable aligned surface.

Today, the plaster grid is used not only as a clutch when aligning surfaces, but also in other repair work. So, a mesh is often used when installing a warm floor system. This material is a clutch for a concrete screed, which covers a warm floor device. Metal mesh is often used to strengthen all sorts of structures, as well as during the construction of cells and the pens. The grid can also be used as a protective covering material.

The selection of its material directly depends on the thickness of the desired layer of plaster.If it does not require a serious alignment, and the thickness of the facing layer will not exceed 3 centimeters, it is quite appropriate to use a fine mesh of fiberglass. This is the cheapest option that has the smallest weight, but at the same time perfectly protects the surface from cracking.

If the layer thickness is in between 3 to 5 centimeters, it is advisable to use a metal grid. It can not only strengthen the layer and prevent cracking, but also eliminates the possibility of detachment of the coating. If the thickness of the required layer exceeds 5 centimeters, ideally it is necessary to abandon alignment in this way, since even the most durable sealing grid will not be able to prevent the detachment of a too thick layer of material.

What is needed for?

In order for the plastered surface as possible for a longer period to save its original appearance, so that no unnecessary detachals, cracking and other material deformations, it is necessary to adhere to a special technology in facing.

The technology is to use the special binder layerbetween the draft wall and plaster, which will be applied to the selected surface. As such a layer and uses a special construction grid. It is she who can create a solid grip of walls and plaster, eliminate cracking and peeling.

Before the external and internal works began to use special grids from various materials, the reinforcing layer of wooden rivers was used to repair them for repair, as well as thin twists, later the reinforcement grid of metal was used. However, this material was heavy enough, its installation was time consuming, so the metal replacement was created sooner and a plastering and lightweight mesh from plastic or fiberglass was created for finishing the facade. This option is simpler to use, absolutely any person can cope with it, in addition, plastic and fiberglass are more convenient in the cutting and much easier than wire options, however, as a clutch and strengthening, the finish is not inferior to other used materials.

The use of a plaster reinforcing mesh is advisable when:

• It is necessary to create a special reinforcing frame, which will not allow the facing layer to sprinkle or crack, which can occur in the process of graining the material.
• It is necessary to strengthen the relationship between two materials that have too diverse composition. For example, without the use of the binder layer, it is impossible to hope for the successful implementation of plastering of materials such as chipboard, plywood, foam, since such materials have too smooth texture for clutch with an aligning mixture.

• You can use one of the materials and for processing joints or seams, which are formed during the installation process of any materials. For example, it is very convenient to handle joints between plasterboard sheets or other sheets.
• You can also resort to the use of the grid during the installation of the waterproofing layer and insulation. Bonding layer is also often needed between these layers and the draft wall.

• The mesh structure is good and for better clutch of materials when installing a warm floor system, it provides a seal of a concrete screed used in the installation.
• In addition, the use of the reinforcing layer is advisable and in the process of installing bulk floors. Here will also be bonding and strengthening functions.

Without strengthening the layer of plastering, it may crack or begin to move out, this is due to the fact that the process of drying the layer, which has a thickness of more than 2 centimeters, occurs unevenly, as a result of which the zonal shrinkage of the material occurs, which can entail cracking and other coating defects. The layer of the grid also provides a more uniform grazing of the material due to the special structure of the cell.

Material in cells dries up much faster and evenly, preventing structural changes both in the repair process and after its end.

It is also worth remembering that such a fortification is necessary not only for internal work, because the outer walls are subjected to much greater negative impact. Drops of temperature, moisture, wind and other natural factors can spoil cladding, so with this kind of finish it is advisable to use a reinforced version, which is called in specialized stores - a facade or grid for external finishing works.

Types and characteristics

So, by defining what a plaster mesh is needed to smoothly move on to the analysis of its species possible, as well as the advantages and cons of one or another option. Today, the construction market offers a huge number of different types: serpent, wire, welded, polypropylene, painting, basalt, abrasive, plastic, metal, galvanized, fiberglass, steel, polymer, cape, assembly. They are easy to get confused and choose absolutely not what you need.

When choosing, first of all, it is necessary to understand that all the options presented are divided into those that will be used for interior decoration, and those that can be used for external facades. They will have the strength and materials of manufacturing.

The most popular materials include:

• Plastic.This material is one of the most durable options. It can be used both as a layer in interior decoration and in external. This material is better than others suitable for strengthening and leveling the brick wall. Due to this combination, the plastic grid can often be found called masonry, since it is often used in the process of wall masonry. It allows not only to obtain a faster grip of bricks, but also reduce the solution consumption, since the layer may be more subtle.

• Another popular option is a universal grid.It can also be used both for interior decoration and external work. However, the universal version also includes three subgroups whose definition depends on the sizes of cells. Determine: small, here the cell size is minimal and equal to the measurement of 6x6 mm; Middle - 13x15 mm, as well as large - here the cell size already has dimensions of 22x35 mm. In addition, depending on the type and size of the cell, the scope of application of one or another option will be determined. So, small cells are the most suitable option for decoration of the walls and the ceiling in residential areas. The average grid is usually made of polyurethane, which provides additional stiffness and strength, its scope is also limited by internal work. But large cells can be used when cladding external surfaces.

• Most suitable for use in very embossed surfaces is fiberglass mesh. This is one of the most durable and easy-to-use universal materials, which is also suitable for both external and internal finishing work. Reinforcement using this type is the easiest due to the fact that fiberglass is absolutely not fragile material, which means that even the strongest germs and deformations are not terrible. Thanks to this property, the material is almost the most popular option used in repair work. In addition, the cost of its sufficiently low and payback will occur very quickly.

• Polypropylene is another popular option. Due to its lightness is the best option for the ceiling finish. In addition, polypropylene has unresponsiveness to various kinds of chemicals, and therefore can be used in a complex with a variety of mixtures and materials. Polypropylene grids also have several varieties. The type is determined by the size of the cells.

For example, the best option for the ceiling finish is a plarimate - a polypropylene mesh with cells of 5x6 mm.

For the maximum thick layers, it is recommended to use a polypropylene version that has the name of the Armaflex. Thanks to reinforced nodes and cells with 12x15, it is that it is capable of withstanding maximum loads and ensure strengthening even the fattest and relief walls.

A polypropylene syntoflex is performed as a universal finishing material, it may have the sizes of cells 12x14 or 22x35.

• Metal grid does not lose popularity.The sizes of cells here can range from 5 mm to 3 centimeters, but variants with a size of 10x10 and 20x20 are greater popularity. The scope of application, however, is limited only by internal work, since the metal is extremely exposed to external natural factors and can be tritely covered with rust even under the layer of plaster, which can spoil the appearance of the facade, not to mention the fact that the material will lose its functionality.
• Galvanized gridit may well be used for external work, since it is not affected by external factors.

What use?

It would seem that there is nothing complicated in the choice and installation of a particular grid, it is worth only to choose an option value and appointment, but it is also worth paying attention to some nuances that can be a determining factor in choosing one or another option.

There are two main factors that will be determining In choosing a suitable grid. This is the material of the roughing surface and the thickness of the plaster layer. This thickness will be directly dependent on the initial relief of the wall.

Depending on the material of the wall, the mesh material will be selected, as well as the method of its attachment. So, for cement, aerated concrete blocks and brick walls, fiberglass or plastic is better suitable, the fixing occurs with the help of a dowel.

On wooden surfaces, consolidation occurs with galvanized screws. Metal bases can only exist with a metal grid, and the fastening process occurs with the spike with a welding machine.

On the foam and paint, as well as for ceramic surfaces it is better to use light polypropylene, plastic or fiberglass.

Polypropylene often does not require additional fastening, it is easily attached to the wall with the lubrication, but it is worth considering that polypropylene cannot be used on too uneven surfaces, the so-called extreme, where too thick layer of plaster is necessary.

In the process of determining the thickness of the layer required to level the wall, it is necessary to use a special tool - a building level. With it, it is necessary to find the lowest point and focusing on it, to determine the thickness of the future layer of plaster.

Depending on the measurements obtained, you can also select one or another option.

So, for layers of plaster lying within 2 to 3 centimeters, it is advisable to use fiberglass, plastic or polypropylene. If the layer is more than 3 centimeters, it is recommended to use a metal grid, pre-fixing it on the wall, otherwise the finished design will be too heavy and just fall off under its own weight. In cases where the required layer becomes more than 5 centimeters, it is better to pay attention to other alignment methods, for example, on the drywall. This will significantly reduce the cost of dry mixtures and will significantly speed up the process.

Another significant factor when choosing a grid will be its density. The higher the density, the better reinforcement.

In terms of density indicators, all grids can be divided into several groups:

• 50-160 grams per quarter. meter.The use of such a grid is most common when furnaceing apartments. Differences in these options only in the size of the cells, which in itself slightly affects the reinforcement indicators, and therefore depends on the choice of the buyer.

• 160-220 grams.Such mesh is an option for an external finish, they are not afraid of temperature drops and can withstand thicker layers of plaster, can be used on extreme walls and other structures, such as furnaces. The size of the cells here is usually 5x5 mm or 1x1 centimeter.
• 220-300 gram- reinforced mesh options. They are able to withstand maximum loads and extreme conditions.

It is worth remembering that the higher the density of the grid, the more its cost.

Installation

Mounting nuances will depend on the following factors: the material of the wall and its condition, type of grid, as well as the thickness of the plastering layer. Since today the most popular options are fiberglass and metal, it is worth considering the mount on these examples.

The technology of fasteners of the metal mesh and the further plastering of the surface is very simple. First you need to fix metal cuts on the draft wall. This stage is necessary, since the metal has a sufficiently large weight, and with the plaster, it will also increase that entailing the design of the structure. It is also necessary to remember that in order to set the grid to the external facade, it is necessary to purchase a galvanized version that will not be afraid of extreme conditions of existence.

In addition to the grid itself, the laying will require dowels and a special mounting tape. It is necessary to start mounting the grid from measurements, it will help cut off the desired segments and cover the entire surface to be treated.

At the next stage, it is necessary to drill holes under the dowel. The distance between the holes should be about 40-50 centimeters.

In addition, it is worth withstanding chess order in placement.

The installation begins from the top corner at the ceiling, this particular option is the most convenient and correct. Screwing the screws into the wall and fixing the material, it is necessary to use special washers or mounting tape, the pieces of which must be pushed under the screw of the self-press. In addition to self-samples, it is possible to use a dowel of nails, which are simply driven into the wall, which significantly speeds up the process. On the wooden surface, the grid can be fastened with a conventional furniture stapler.

If one layer of the metal grid turns out to be not enough, the volume can be increasing, in this case the backstage between the formation should be about 10 centimeters. After the entire surface being processed is covered, you can start coating with plaster.

Fiberglass grid can be pulled in several ways. This is a very convenient material for interior decoration and can be used by a master with any experience. In addition, fiberglass has low cost and very convenient in the installation.

When building construction structures there is a need to ensure increased strength and stability of parts of the structure using fittings. For masonry, enhancing a concrete screed, enhance the strength of the layer of plaster, as well as the strengthening of the facades of buildings, a reinforced grid is necessary. It is also used for and foundations. The coating of the reinforcement mesh surface of the walls provides durability and increases the adhesion of the finishing solutions. Grids are made of various materials and differ in complex characteristics.

For which the reinforcing mesh is applied

When performing construction activities, cement solutions, concrete mixtures, as well as finishing formulations are widely used. After the frozen, they acquire strength, but are cracking under the influence of bending loads, deformations and torques associated with the shrinkage of the structure and the impact of various factors. Increase the resistance and strength of the erected structures allows reinforcement grid. It ensures the integrity of the binder or finishing composition after solidification, increasing its mechanical strength.

To fulfill finishing and building events in specialized stores, an extended range of mesh amplification with small and large cell sizes is offered.

Reinforcing grid applies to ensure the durability of building structures

Depending on the size of the cell and material used for manufacture, the grids are used to perform a wide range of tasks:

• increase the strength characteristics of foundation grounds. Without additional reinforcement, the foundation under the influence of natural factors cracks, gradually causing the shrinkage of individual parts of the structure;
• prevent cracking of the screed when pouring floors. Especially relevant use of the grid when used as a heat insulator of fragile foam sheets. The grid ensures the integrity and durability of the array, preventing the formation of cracks;
• increased adhesion between the finishing composition and the surface of the wall. The grid provides an improved contact of the plastering solution applied from the outer or inner part of the structure. When finishing wooden, metal, as well as painted surfaces, the grid is necessary;
• ensuring the increased reliability of fastening the finishing materials and decorative coatings to the surface. The mesh reinforce performs the function of the binder element, providing durable contact with the base of facing materials and various types of finishes;
• improving the contact of the plaster mixture applied to the surface of the sheet foam or drywall. The finishing operation will not give the proper effect without the mesh reinforcement. Without reinforcement, when performing plaster events, the cracking of the plaster mortar is inevitable after frozen.

With an increased thickness of the finishing composition of more than 20 mm, the net reinforcement does not allow the integrity of the protective and decorative layer after hardening. This area of \u200b\u200buse of the grid is not limited. In demand when the walls are erected to increase the strength of aerated concrete or foam block. The mesh material also applies to the draft ceiling surfaces.

Reinforcing grid there can be different types

Varieties of used grids for reinforcement

Grids used to solve construction tasks and executing finishing measures are divided into groups depending on the material being used for their manufacture, cell size and production technology. Each species has its advantages, is characterized by the performance characteristics, specific use and cost.

The consolidated grids are divided into the following types:

• metal mesh reinforcement;
• plastic materials for reinforcement;
• fiberglass gain.

Let us dwell on the features, varieties and use of each type of mesh material for reinforcement.

Application, types and advantages of metal mesh

The metal grid reinforcing is widely used material for hardening various surfaces.

Metal grid is used to arrange a reliable screed

Mesh material made of steel is used for numerous purposes:

• arrangement of a reliable screed when pouring outdoor bases, including for heated floors;
• ensuring reliable contact of the plaster material when eliminating significant defects on the surface of the walls;
• preventing the binder from extinguishing the binder from the treated surface and prevent local exhausting;
• enhance the stability of the walls whose laying is carried out from cellular aerated concrete and foam block blocks.

The diameter of the cross section of the wire and the sizes of the cell differ depending on the purpose of the reinforcing material:

• for plaster events, a mesh reinforcement from steel wire with a cross section to 1.5 mm is used. The cell has a square shape, its side does not exceed 30 mm;
• strengthening the screed is performed by a reinforced grid. Wire diameter exceeds 3 mm. A mesh with a square cell is used, the side of which is more than 100 mm.

According to the wire sorting and the size of the cell, the mesh material for the reinforcement of the walls corresponds to the size of the plaster grid.

Steel grid comes in a different form:

• roller. Such a grid is used for plastering;
• sectional. The material is used for screed and masonry.

Depending on the design features and manufacturing techniques, various types of steel mesh are applied:

Steel reinforcing grid is divided into several types

• welded. It is made by fixing perpendicularly arranged steel rods point welding in the crossing places. For the manufacture uses wire of different sections. The number of the welded grid corresponds to the side of the wire cell. To protect the grid of corrosion, the wire is used or a polymer coating is applied. Non-galvanized mesh is also used in the construction industry;
• non-exhaust. It is performed on special equipment by stamping a solid sheet metal, followed by stretching the stamped sheet. Sustainable material is used for reinforcement when performing masonry work, as well as in the process of facing events. To prevent corrosion destruction of the steel mesh, the material is electroplated;
• rabita. It is made of carbon steel by forming zigzag wire segments with a further connection of them in a solid canvas. For the manufacture of the chain, a wire with alloying additives and a protective zinc coating is also used, which increases the corrosion resistance of the material. The chapter is traditionally used for the reinforcement of the walls on which the enlarged layer of the plaster mixture is applied.

The main advantages of the steel mesh:

• simplicity;
• material flexibility;
• increased margin of safety;
• resistance to temperature differences;
• saving integrity when cutting.

The advantages also include the convenience of transporting a rolled material and a small mass of sectional elements. Thanks to a complex of advantages, the steel grid is used to solve various tasks in the construction industry.

Types, use and advantages of plastic grids

Plastic mesh produce from polymeric materials, characterized by increased strength.

Plastic grid has a different thickness

For the manufacture use various types of plastic:

• polyurethane;
• polypropylene.

The mesh base has a different thickness. The reinforcing material is characterized by a cell configuration, which has a rhombus or square shape. Plastic grid is used to perform work on the outer and inside of the building. For installation of plastic reinforcement, special preparation is not required. Initially, it is applied to the surface of a thin layer of plaster composition, followed by pressing the grid in it. The main applications are the execution of work on the application of plaster and facade reinforcement.

The main advantages of plastic mesh:

• increased resistance to stretching;
• resistance to the effects of high humidity and temperature changes;
• environmental purity;
• affordable price.

The material easily takes the form of radius surfaces, safely in contact with electrical wires and does not have a negative impact on receiving radio signals.

Fiberglass reinforcement grid

Fiberglass mesh material for reinforcement on operational characteristics is similar to a plastic grid. The operational properties of fiberglass tissue are determined by its density.

Fiberglass mesh is designed for external and internal plaster plaster

It is this indicator that determines the stock of the reinforcing material, its reliability and scope:

• the execution of finishing works inside the room is carried out by a grid, the density of which does not exceed 160 g / m2;
• for the exercise of the facade finish and performing external plaster, a fiberglass grid with a density of up to 220 g / m2 is used;
• the strengthening of the base part of the structure and the reinforcement of loaded structures is carried out with a reinforced mesh whose share of which reaches 300 g / m2.

Fiberglass mesh is sold in a roll or ribbon form. It is designed to enhance drywall connects, increasing the adhesion of finishing material and prevent cracking.

Advantages of fiberglass mesh:

• increased strength;
• increased moisture resistance;
• acceptable cost;
• warredness for others.

Application for the manufacture of glass fibers resistant to aggressive media, increases the stability of the grid to working solutions and alkalis.

How used reinforced grid for enhancing building structures

It is necessary to study the installation technology and the mounting rules when the reinforcing grid is applied. How to use mesh material, can be found on construction sites.

Fastening the reinforcing mesh on the wall occurs by pressing the plaster mix

Mesh mount options:

• with the help of electric welding, which allows you to attach the steel mesh to a metal basis;
• stapler providing reliable fastening of plastic mesh brackets to a wooden surface;
• curved nails, self-drawing or screws that allow to press a thick grid to the base;
• special dowels intended for fastening reinforcing material to brick or concrete walls;
• by pressing the plaster mix when performing finishing events.

You can install the mesh installation without fixing when the screed is performed.

Having decided to use the reinforcement grid, consult with the seller-consultant in a specialized store or use the qualified advice of professional builders.

Pay attention to the following characteristics of the material:

• basic material;
• diameter of jumpers;
• cell dimensions;
• the presence of coating;
• strength properties;
• material quality;
• preparation method.

Choose a material with increased strength with an increased resistance to an alkaline environment. Errors in the selection of the grid cause the formation of cracks due to the destruction or insufficient strength of the mesh reinforcement.

Conclusion

A qualified selected reinforcement grid will ensure the required margin of safety, will retain the integrity of the binder material, and will not allow the formation of local defects on the surface of the walls. It is important to deal with the varieties of mesh reinforcement, study the specifics of use and select the necessary grid for cementing a screed, applying plaster or performing other types of work on finishing and facing.

Repair is often accompanied by alignment of walls with the help of plaster. In addition, it further improves thermal insulation, reduces the level of foreign noise in the trimmed room. Watching decorative surface mixtures have a beautiful appearance. When the irregularities are small and practically no defects, then the solution is often applied simply for the prepared base. If the deviations are large, there are cracks, then a plaster grid is used in operation for reinforcing walls. It is represented by a wide range, which allows you to choose products under certain operating conditions.

Area of \u200b\u200buse

The reinforcing mesh for the plaster of the walls replaced the old methods (dranco, nails stuffed) used to improve the adhesion of the finishing layer with the base surface. It is made from different materials differing in their properties. Products from a large number of different manufacturers are presented on the market.

It is used for both internal and external work. It is the basis of the leveling coating. The latter as a result becomes more durable and durable. The grid must be used to avoid the appearance of detachants, cracking, or stop the process of cracking itself.

The construction grid for plaster is used to qualitatively prepare the basis for further measures to decorate working surfaces. With proper installation and further plastering, it prolongs the service life of the finish and contributes to the preservation of the integrity of partitions.

Types of plaster grid

The reinforced grid for plaster differs according to the materials used for its production, the structure and sizes of the cells, creating methods. According to the first criterion, such varieties are distinguished:

• plastic;

Products are inherent in all the advantages and disadvantages used for their production materials.

A more detailed classification is presented in the table below.

View	Cell size, mm	Characteristic
masonry (painting)	5*5	plastic canvas used when working outside and inside buildings using gypsum blends
universal: small, medium, large	6*6, 14*15, 22*35	small-friendly option - a suitable grid for plastering of the inner walls, and the largest well withstands the temperature differences and the load outside
flusket	5*5	durable, resistant to moisture, cold and heat, chemical compounds
plurima	5*6	produced from polypropylene, inert, chemically, used for external and internal works

The existing range allows you to choose quality products, taking into account all the requirements. The use of the material that corresponds to the existing conditions determines the durability of the finish.

Choosing a working material

The main determining point in the selection of the material is its suitability for specific conditions, so the grid under the plaster walls is selected taking into account the following range of factors:

• required thickness of the finishing coating created;
• type of plaster mix, which is used;
• layout (concrete, wooden, brick, porous materials, stone);
• external conditions in which a formed plastering layer will be: outside the building, inside, or in the premises of non-heated, wet.

Watching with such types of mixtures:

• cement-limestone;
• plaster;
• cement-sand;
• clay and others.

Various additives are often added to such compositions. They together with the main components have a certain level of chemical activity. What causes the degree of their influence on different materials from which the grids for reinforcement are made.

Taking into account the above provisions, the basic guidelines for the selection of the grid for plastering the walls are:

• fiberglass products are recommended to use with the thickness of the plaster layer being created up to 3 cm, when there are also recesses, cracks to stop the expansion of old and education new;
• if the height of the formed coating exceeds 3 cm, then a more appropriate option will be made of metal: it is able to withstand the weight of the finish and not be compressed at the same time;
• plastic products are better to use plaster solutions for insignificant thicknesses, and, for example, cement-sand formulations over time corrosive such reinforcing material;
• when using clay-based mixtures, and when there are significant irregularities on the surface of the base - the metallic options are relevant;
• plastic cloths having small cell sizes (for example, 0.2-0.3 cm) are used during finishing putty;
• fiberglass, or galvanized (ordinary metal are not suitable), products are a good way to reinforce rooms with high humidity;
• when there is a need to plaster the furnace with cement-clay solution, then the chain can be used, and with a thin layer, fiberglass;
• steel products are suitable for co-use with the compositions containing cement;
• during the plastering works on the finishing of the outer walls of the house, the material with cells 3 * 3 cm are usually used, and more large dimensions are selected for the surface;
• for internal work, mainly the material is used in rolls, and for external - as sections.

When the height of the created layer of plaster does not exceed 2 cm, then the reinforcement can not be carried out. Following the presented recommendations will allow you to choose the most practical material.

Features of the installation of different types of grid

Metal mesh for plaster, fiberglass, or plastic, can be mounted using different ways. The selection of the calculation variant is determined by the composition of the working mixture, the material from which the grid used by the plastering technique is made. Fix with:

• self-tapping screws or dowel-nails, screws.

The first layer of plastering for alignment of the walls is reinforced, pressing the mesh into the solution applied to the surface of the required thickness.

The optimal way to create a finishing coating (crossbar or decor) is the fastening of the adhesive canvas on a dry base with special fasteners.

When the area of \u200b\u200bthe separated area is small, then you can use the working mixture for fixation, applying it point.

The painting mesh is sufficient to simply fix the thin layer of the solution.

Fiberglass canvas are mounted according to the following optimal algorithm:

• perform markup for the installation of beacons;
• it drills holes in which the dowels are then inserted;
• put screw screws in terms of level;
• cause a solution to a plot equal to the width of the used web;
• on the plaster immediately impose a grid, which makes caps of screws from her;
• make a mixture further;
• vangest (10 cm) fix the following lane;
• so continue until all the premises reign;
• install lighthouses.

The solution should be smoothed by the canvas evenly, starting from the middle of the strip, moving towards its edges. When creating a thin layer, fiberglass fastened itself to the brackets with further putty.

The plaster metal grid is fixed in such a sequence:

• purified from lubricating composition, flushing with water or wiped with a moistened cloth;
• scissors for metal are cutting the canvas into pieces of the desired dimensions;
• drilled every 25-30 cm with a diameter of 6 mm under the dowel (a depth of about 3 mm greater than the length of the plastic part of the fastener), insert them;
• using screws and mounting tape - fasten the material on the surface;
• the following fragments are laid with 10 cm overlap;
• mount lighthouses.

The minimum height of the coating created depends on the thickness of the grid wire. Metal products additionally strengthens the base, and fiberglass - performs reinforcement of plaster mesh.

Methods for fixing the plaster grid are considered in detail in the video below.

Installation of facade fiberglass material is shown in the roller below.

Strengthening the foundation, increasing strength and reliability of plastering finish - all this is ensured by creating a clutching layer. It is formed using different materials.

To properly perform the reinforcement of the walls of the grid, it is necessary to take into account the type of solution used, the installation site (outside, or inside the building), the intended coating height. It is also required to use the appropriate installation technology. Compliance with the listed conditions allows you to highlight the walls or ceilings qualitatively, minimize the possibility of cracking, do not be afraid of shrinkage at home.
