When conducting plastered surfaces, the reinforcing grid is often used. The material allows you to apply a thicker layer of repair composition on a construction base. To obtain a satisfactory result, it is recommended to familiarize yourself with the types of grid, the rules of choice and with how the plaster walls are performed by the grid, and video instructions for work.
The grid for plastering walls is the material that is used to increase the strength of plaster, as well as preventing the formation of cracks, peeling the material and distortion of the finishing finish. The grid improves the adhesion of the construction base and repair solution. The material increases the stainlessness of the plaster to the effects of moisture, temperature drops and mechanical exposure.
Stuccoings of walls with a grid can be performed for:
The grid for walls under the plaster has several varieties. To choose the material, it is recommended to familiarize yourself with the characteristics of each.
it plastic grids. Such material is in high demand at the finishers. The product is produced with cells of different sizes. It is used even for uneven surfaces with large drops. The advantage of the product is an acceptable price.
Such a grid is used mainly for outdoor decoration. Material has increased strength, it is applied even for uneven walls with large drops.
Metal grids are divided into several types:
The grid for plastering walls of fiberglass is a thin material with small or large cells. The first view is used for interior decoration. The grid is fixed to the surface without high drops and defects. Typically, the material is used under gypsum compositions. The product from fiberglass with large cells is used for facades. Such materials are withstanding an increased load.
It is a thin fiber from polyvinyl chloride. A distinctive feature is increased resistance to chemicals. How to plaster on the PVC grid, presented on video lessons.
If we talk about what plaster is used a mesh, it all depends on the composition of the product and its effect on the material. If the product contains aggressive chemical compounds, then it is recommended to use a grid of polyvinyl chloride. For the remaining materials, plaster, cement-sand and cement-limestone plaster are suitable.
How to lay a plaster grid depends on what type of material is used for reinforcement.
Before starting work, the grid is cut into small pieces for the convenience of fixation. Then they are mounted on top of each other.
There are two ways to pull the plaster grid made of plastic.
The grid under the plaster of walls from the metal is attached in the following sequence:
The technology of plastering walls on the grid assumes that the gap between the wall and the metal product should be 3-5 mm.
The material is tensioning so that there is no savory (as in the photo below).
Before plastering the walls with the grid, the surface must be prepared: dismantle the old finish, deny and degrease the surface. Next, the base is so ground. Primer is applied twice and after each processing make a break for drying. Then the mesh is fixed on the surface.
After the reinforcement of the building grounds establish beacons.

Wall shocking technology on the grid:
The video in this article shows how to plaster with a grid building base.
Plastering walls with a reinforcement of the grid - the stage of finishing, which allows to align even a building base with large drops. The main thing is to act in accordance with the technique of applying materials.
Conducting work on plastering surfaces is an important and responsible task. Need to be observed right technologiesthat will allow without unnecessary difficulties to securely consolidate the material on the wall so that it does not be peeled under any circumstances.
The grid reinforced for plaster is best suited to solve the specified question, since it can be created with its help a special layer, which on one side will improve adhesion with the wall, and on the other - will allow reliably to make the material together. This approach is used when performing a large amount construction workAnd he proven himself only with the best side. So it is used everywhere and always be satisfied with the result.
The reinforcing grid for the plaster walls is fully consistent with its name and is a special product that has small cells, allowing you to effectively restrain the solution so that it is not spilled in different directions and kept tightly on the wall.
Distinguish the following varieties:
The range of products is quite large, so you need to know how to choose the material when buying. The sales consultant will try to implement that product that is beneficial to him, so it's better if the client himself understands the varieties.
In inexperienced users, quite often the question arises, what is the grid reinforce the plaster? Here everything will depend on the current working conditions, since there is not only universal models, but also narrow-profile products suitable only for one purpose. Therefore, it is necessary to preliminarily consult with masters or independently search for the necessary information. Right choice It is very important for further operation, so you need to treat him with the rest of the severity.
The reinforcing mesh of fiberglass for plaster is one of the best universal models, as almost all positive qualities in themselves, which should have such material. It is not afraid of corrosion, since it does not contain metal elements, not sensitive to moisture and temperature differences, well withstands mechanical loads. Therefore, many professionals are advised to acquire this model.
In any case, the reinforcing grid for plastering walls according to its operational qualities should not be given to the main material. This is especially true of strength, reliability and durability. The basis is simply obliged to simultane at least finishing materialotherwise everything is lost in its use.
The reinforced grid under the plaster should be securely and tightly attached to the wall so that it does not violate right Balancewhich will be established upon completion of the finish. Its installation is made in the phased mode according to the following scheme:
The price of the reinforcing grid for plaster will depend on the selected view. The larger the size of the cells, the cost of the material, respectively, is more expensive.
Stucco on the grid - effective method 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.
There are several types of products used for reinforcement, the main materials are the following materials:
Types of reigning mesh: a - metal; B - fiberglass When applying a thin layer of solution on smooth surface Usually used fiberglass cloth. 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:
To work with a metal grid, you will need selflessness, construction dowels and a metal mounting tape.
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.
Even when using the mesh, the surface needs to be prepared:
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:
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.
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.
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. The most difficult cases are a thick layer of plaster - more than two centimeters, and the surface of the finish, not characterized 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.
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 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 under the stucco is very important. It does not matter whether the layer is reinforced or not - cleaning, dedusting, removing all the old peeling finishes, as well as processing penetrating primers or primers - a prerequisite 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.
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.
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.
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.
Apply for mechanized finish large squares - warehouses, hangars, public facades and production buildings et al. Cell 20 * 20mm, 30 * 30 mm, 35 * 35 mm, a grid is produced in rolls.
For strength has best featuresthan 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.
Fiberglass meshs are divided into density groups - the higher the density in g / cm2, the stronger the reinforced layer.
For internal plaster Apply painting and plastering foxes. 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.
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 Works and large loads belong to 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 undergo special processing - impregnating 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.
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.
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.
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.
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.
For plaster produced and special view Plaster grid - 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.
We are manufactured both wicker and from solid metal sheets with a thickness of 0.5 -1.0 mm with an extract and spacing sheet. 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.
The grid increases the strength of the solution when it is applied to extensive areas and transitions between different materials walls. The plaster of the facade on the grid is necessary when working in new buildings, the walls of which are still allowed.
The reinforcing material may be metallic, polymer or fiberglass. Its selection depends on the application.
Often applied to concrete, brick and wooden facades The finish cracks and peeling. So that this does not happen, the surface is reinforced by the grid.
Woven grid. This is a thin, but durable and flexible material, woven by weaving from wire of various sections. A grid having square cells 1 × 1 cm and zinc coating. Sold in rolls.
A woven mesh or chain has a cell diameter of 2 cm, used to strengthen significant layers.
Types of metal nets
The welded grid has square cells. It is performed using point welding of the crossing of the wire, the rods of which are perpendicular to each other. The material is galvanized or polymer coated with polymer composition. Light low carbon wire. Applied welded grid To prevent trim cracking with active sediment. We recommend using a mesh with cells in 2-3 cm.
It is manufactured on a special press from metal sheets. The material obtained has a diamond-shaped cell that are located in a checker order. Used with relatively. Rolls have a width of 1 m.
With a fairly thin layer of plaster, a grid of fiberglass or polymers is used.
Polymer mesh (price - from 2150 rubles)
Use a metal grid when applied with a finishing layer from 3 cm and above. The chapter is applied to reinforce anything else.
Roll the grid roll. Measure roulette the height of the surface from the roof to the soil. Cut the required number of planets with scissors for metal.
Reconflate and fix the grid with screws or nails on the primed surface so that the adjacent canvas laid 10 cm.
Mix the solution with an antiseptic. The latter will be a guarantee that mold spots will not appear on the surface.
Put the first primer layer of the solution with a shovel or trowel and recall the rule. Let the mixture dry and apply the second leveling layer. It is thinner, so distribute it to a celma or a large spatula.
If the mass lay unevenly, after its complete drying, we recommend using the finishing putty. When it harnesses, tell the shallow skin of irregularities.
The polymer grid is often used. It has resistance to chemical impacts, so does not spoil the finish coating during operation.
Measure the roulette and cut the mesh cloth. If the base is dense, apply a thin layer of the solution and press it with reinforcing material. If the walls are porous or wooden, you can fix the grid in the stapler.
Securing it, evenly distribute the mass throughout its surface so that the network does not look out.
Plaster on the grid - the technology of work with polymers:
Start applying a solution from the middle of the canvas and continue moving to its edges, as if you glue the wallpaper and drive air from under them.
Note! Polymer grids have elasticity, so stretch. Work carefully and prevent the formation of bubbles from the reinforcing material.
The most common method of applying the finishing coating both on and on the internal is their coloring. Before work, estimate the quality of the foundation, choose cracks if necessary, make sure that the layer has a solid connection with the surface, does not peel and cover the walls.
Note! If the finish is fresh, it may have an excess alkali, therefore, apply solvent-based compositions is undesirable. Using organic soluble paints, consider that the surface must be protected with synthetic primer.
Council on the topic than to paint the facade plaster. It is better for this purpose to use alkyd, acrylic and latex formulations.
On the rolls there are always instructions for plating material and recommendations for the selection of glue. The technique of working with wallpaper on plastered walls does not differ from similar operations on other surfaces.
