When finishing ceilings and walls and quite often, plaster and grid under the plaster are used.
Plastering does not always be perfectly lying on the surface. In order for the layer of plastering to fix better, you can use a plaster grid.
Earlier, for these purposes, a wooden dranco (for wooden surfaces) was used, the brick was placed without preparation - its shrimps and seams were a sufficient condition for the good clutch of the plaster layer with the wall.
The grid under the stucco is used so that the plastering layer is firmly. The fact is that with a carefully prepared surface under the plaster, the solution can sometimes lie as much as necessary. This may occur in case of assumptions of some errors when plastering: non-compliance with proportions, temperature and humidity level ...
In order to avoid such errors, it is necessary to use plaster grids, thanks to which the negative consequences of plastering are significantly minimized. These grids are designed to take the load that may occur due to improper use of the room.
The grids are used for the reinforcement of walls before painting (blowing wallpaper). The grid gives the plaster the greatest strength, increasing the service life. The use of grids for walls with meaningful defects is especially valued, when it is necessary to apply a thick layer plaster.
Before purchasing a grid under the plaster, it is necessary to pick up the one that is suitable for a certain job.
Mesh types under the stucco are quite a lot. When choosing the one that is needed for certain works, you need to focus on the features of the mesh type and the size of its cells.
Distinguish the types of mesh:
When choosing a plaster grid, you must pay attention to what kind of work you are going to perform. That is, you need to know the thickness of the layer of the future plaster. Namely:
Decide on the choice, and let all work work will be done on "excellent."
Knowledge of how the plaster on the grid is carried out, it allows you to skillfully act when the risk of sliding the solution is arising. So that this does not happen, the wall is strengthened with reinforced material. Does the grid need a plaster? As a strengthening layer, it is simply necessary.
The solution on the walls is delayed in the cells of the canvas and does not flow down. After the simplicity of the applied mixture on the surface of the walls, a durable durable coating is formed. There is a thickness of 10 mm thick, it can do without reinforcement. With a thicker coating, the installation of reinforcement is required.
Modern technologies of plaster on the grid use several types of reinforcing materials:
Similar small grids are used on surfaces with non-critical defects Fiberglass mesh for plaster is a thin fine-skinned canvas.
Plastering of walls on the grid of this type is applied on the walls indoors. Fiberglass canvas are fixed on surfaces that do not require special leveling.
Usually such a mesh is covered with a thin layer.
Last time plastic acquired great popularity. Polymer canvases in their support ability in some cases are equivalent to metal reinforcement, and at an order of magnitude lower.
Polymer grids do not lose design You can always find a polymer mesh with various cell sizes and thickness. With its help, you can align the walls with the deficits of the surface to 20 mm per 1 perm.
It is recommended to use metal mesh on surfaces with large defects. The metal grid for plaster is used mainly for finishing facades. Metal reinforcement strengthens the surfaces of fences with complex geometry, the defaults of more than 20 mm per 1 perm.
At metal, it is mainly used in a cement-based mixture.
Metal coatings are produced in several modifications:
Watching on metal grids forms the most reliable and durable layer of wall finishing than based on reinforcement from other materials.
Each type of reinforcement, given the characteristics of the material. For more information about the types of construction grids, see this video:
Secure the grid on the solution Light plaster grid Does not require special fixation.
The fiberglass mesh for plaster is fastened along the perimeter with a solid with a spatula.
The strips are connected to an overlap with a piercing of 150-200 mm, for which, before starting work, the grid is cut into stripes taking into account this intake.
With a particularly complex configuration of the surface of the walls, the canvas is additionally fixed with dowels. If the stripes are placed on wooden surfaces, then fasteners are comfortable to make a stapler.
Plastic cloths are fixed in some cases as well as. In other options, fasteners are resorted to the use of dowels and screws. The material is fixed with a mustache, a calling one strip to another 150-200 mm.
Strengthen the metal grid on the dowel The grid for plastering made of metal withstands rather thick layers of finishing. Due to the fact that such reinforcement has a significant specific weight, the fastening of the metal reinforcement should be particularly reliable. Installation of metallic wall coating is performed as follows:
Reinforcement must be fixed in a stretched state and not fade. Otherwise, it is possible to obtain the formation of voids in the body of the finish, which will negatively affect the bearing capacity of plaster.
When the reinforced canvases are fixed on the fence, install the guide strips (lighthouses) to move the rules on them. Rules are made from a segment of metal profile from 1 to 1.5 m.
The guide strips are fixed with a gypsum solution. The line is controlled by the level of lighthouses.
Fencing with the grid is plastered in 2-3 layers.
Walls are placed in several layers Works are carried out in the following order:
Plaster as a way to protect and refuel the facade has a thousand-year history. In some cases unique effect acquired world fame and significance of the brand, if you remember venetian plaster, imitating marble cladding.
But for any finishing layer from the mortar of the cement-sand mixture, inevitable were cracks and collapsions detached fragments. Plaster mesh helped solve this problem.
Flexible, openwork, knitted or woven - it creates a monolithic framework frame.
The prototype of the plaster grid can be considered common method of lamb wall Under the stucco, with the help of thin narrow dugs, laid cross-stroke - the so-called "duncar". Until now, among the ruins of pre-revolutionary and Soviet buildings, you can see the naked skeleton of a wooden reinforcement.
Creating new materials and construction technologies allowed replace time-consuming process The walls of the walls are very fragile wooden dranco on a fast and reliable way to strengthen rough plaster different species Facade mesh.
Does the grid in the plaster, its advantage:
What requirements presents to the GOST 3826-82 plaster grid:
Reference: The plaster grid is also successfully used in the preparation of the screeds, the fill of the floors for the device "warm floor", when installing thermal insulation attic premises and roofs.
Materials, as well as making methods, several.
Metal (sheet or wire):
Metal grid is worth choosing with galvanized coating or polymer spraying. So she will serve longer.
From polymers (plastic):
Universal (polyurethane) with cells of 3 species:
Fiberglass - fine, ultra-durable, without restrictions in application. The grid is woven from fiberglass with other components and is impregnated with polymer solutions for the purchase of chemical resistance.
Fluster used for:
Important: Each type of grid is designed for a certain thickness of the plastering layer and features of operation. Incorrectly selected reinforcing layer may lead to cracks, irregularities, detachal of the entire coating together with the finish finish.
In the construction and finishing materials market, domestic manufacturers occupy leading positions:
A plaster grid of 1 meter width to trading enterprises in rolls long 30-80 meters (The weight of the roll is 80 kg) with fasteners and fair elements. Retail is allowed to leave the goods by the Match.
Reinforcing grid N. cheap Material, but saves the cost of owner For subsequent repairs and restoration of lost fragments of the facade. Application of a plaster grid in the facade finish gives him representative view. Therefore, costs are justified.
But acquiring material it is necessary to make sure of his quality, what does it say:
How not to remember the folk wisdom about the miser? Plaster grid -it is not a way to shine with your material capabilities, and the calculated long-term investment on the perspective.
Conditions that it is necessary to take into account when calculating the material:
Therefore, for the polymer mesh required 1.1 m² for square. meter Walls, and for fiberglass - 1.15 -1.4m². Specialists recommend providing stock 5% For unforeseen expenses.
Selection of plaster grid depends from the thickness of the finishing layer, irregularities of the walls.
Criteria are becoming:
With significant drops of the thickness of the layer On the entire surface of the wall of the complex facade, it is recommended to refuse plaster and replace it with another type of finish.
The technology of mounting the facade mesh is completely under the power of anything, consider the whole process of the detail.
Clean the wall from raid, traces of masonry work. Align the surface. If the chain grid is used - preparatory work And the primer is not needed.
Protect the surface for porous materials (aerated concrete blocks) - primer deep penetration.
Froze The treated surface and harvest cuts of the mesh material.
When working with a chain chain or welded, her box is made immediately on the wall Using a dowel or frame:
How to glue the reinforcing mesh on the wall video
Polymer and fiberglass put the venge At the starting layer of plaster, while the reinforcing layer is pressed into the solution and is attached to the dowels around the edges.
The starting layer of plaster can be replaced by a special glue for mounting the mesh, after drying the finishing layer is applied. The glue can also be used to fasten the fiberglass to the insulation.
The adhesive layer should be sufficient to place the grid in its middle when indulging. Basis for adhesive fastening must be sucked And the work is carried out at the positive T◦ (not lower than + 5 ° C) On peeled spots and surface pollution.
With essential irregularities The walls need to install beacons (the thinnest layer - 1cm, the thick of it - not more than 5 cm). The solution is applied to the moistened wall, moving upwards.
Finish layer depending on the type of grid and the planned thickness is formed by a wide spatula from the middle to the edges, and, if necessary, in two navigation (with a complete drying of each layer) to flawless wall alignment.
Select the grid to plaster indoors and with facade works. What a grid is in the construction market. Proper fastening different species Grids to the surface.
Often repair work Apply to the alignment of the walls. This is done both in new premises and by major repairs.
And also not excluded alignment of walls with plaster outside the building. For all these works, in most cases, the grid for plastering walls is used. What a grid is used outside, and which inside is discussed below.
Earlier for the strength of the surface, duncar used long time for plaster. It was made of wooden plates, nailed to the base. Now there is a construction market for plastering the grid. They are different in colors made of material. Serve for better adhesion with the surface, there is no detachment of the applied layer from a rough base for a long time, there are no cracks after drying the solution. After applying the material under the plaster and drying the solution, it is applied to a decorative finish, without fearing that defects arise under it.
The construction market is full of a variety of cellular material for plastering the surface. Basically, they are made from:
Each mesh is designed to keep specific work. a brief description of Presented in Table:
For each type of work, various cell sizes are used.
To work on the street with walls of buildings, you need to take into account many factors:
To select a cellular material, these indicators take into account:
Mainly apply a metal canvas. However, produced fiberglass for facade works. It should not stretch, break.
This is a universal canvas used indoors and outside. Its function includes surface protection from mechanical effects, strengthening the plane created. The grid does not give up the solution (this concerns cement mixtureshaving a shrinkage).
Production is made using wire or metal-roths. Depending on this, the material is divided into light, medium, heavy.
Features of metal cloths:
The disadvantage is the weight. The canvas is fixed only on durable draft bases.
Do not apply on a hollow brick.
To cover the surface indoors finishing material, paint, it should be perfectly smooth and durable. There should be no cracks, chips, emptiness. A painting grid is used to align and create a solid base.
We produce a canvas of polymers or fiberglass. It is safe for health, durable, does not react to moisture and is not deformed.
Apply on different surfaces: concrete, brick, foam blocks when applying a solution with a thickness of 2 to 5 mm.
Before applying the solution, the canvas are attached to the rough base. It should not be saved or being strong.
The material has differences in cell sizes. This is important applying various solutions on the squares from the minimum to large.
The canvas, cells 2x2 is durable, resistant to the aggressive environment.
It is used for ceilings and walls indoors. The function is to prevent the appearance of cracks on the surface created after drying.
Features of the material:
Cons of material:
Despite the disadvantages of the material, it is used for a wooden base, which allows it to align and make it durable.
The reinforcing grid is carried out under a certain type of work. To determine the selection, there are several rules:
These rules will help in choosing a cellular cloth for certain works.
For internal work Apply several types of grid.
Attention. By applying a cellular cloth, the work passes quickly, with ease. The surface comes to solid and has a long service life.
To work with the surface on the street you need to choose the right grid. To do this, are guided by the rules:
Fiberglass canvas. Work with small square meters of the facade surface.
Metal applicable:
Reinforcing metal is in such options:
For various works apply different types Grids.
If you do not apply the reinforced fabric, peeling plastering from a draft base can occur. This will affect its own weight - the thicker the plaster layer, the harder it. Due to the grid after drying the solution, a monolith is obtained.
Applying the grid, it is possible not to worry about the fact that over time there will be cracks of different character.
Even if the solution was made incorrectly (liquid or vice versa thick) stack, it will be clutching it with the surface and will not give destruction, squeezing, flowing.
The reinforced material used in plastering walls and the ceilings should be properly fixed to the base. Each type of cellular canvases is fixed according to the specified technology.
Some types of mesh can not be pulled out or allowing savings. This may lead to serious consequences.
Metal Metal Fasteners Machinery:
Metal leaf stretch, without sagging.
The decorative reinforcing canvas is fixed using ordinary self-tapping screws. They are not completely screwed into the rough base at equal intervals. They dress the mesh and completely twisted into the base.
Attention. The grid should not be strongly stretched, but also no savory.
There is an option to mount on the mounting tape. However, there is a threat of a breakdown of the canvas from the surface during plastering.
The reinforcing canvas gives strength to the ground. It will not depart from the draft wall, the ceiling and will not ride the belly. Stucco with a mesh durable able to withstand the load decorative finish. Therefore, making sure that the walls or ceiling are plastered with the use of the grid, you can safely glue any type of wallpaper, without fearing the appearance of the cracks under them or the discharge of the base.
One of the main advantages is the superimposition of the solution. And if the gypsum mixture lies well on the base, then it is difficult to work with cement material. It is the grid with its cells by its cells on the surface to frozen and does not give a strong shrinkage.
After the material is frozen, the plastered wall can be spitted without fear. It can be painted and covering decorative plaster. There is no threat that the crack will appear in the middle of the wall because of the shrinkage of the house.
The tile masonry is also possible for a reinforced wall. The use of the grid gives the surface rigidity for a long time.
The reinforced grid must be applied in plastering. For each material - metal cells, polymer, characteristic of a specific application. Properly securing the grid and plastered the wall or ceiling, the surface will be in advanced form up to 20 years.
Wall shockting is an easy process, but sometimes the risk of a mixture is risk. It is in such a situation who cannot do without reinforced grid. Although the question often arises whether there is a need for it. To make a finishing of high-quality and reliable, this is the best solution.
The plaster on the grid is placed in cells and no longer flows down. When such a coating is frozen, it turns out reliably and durable. According to the masters, this method is becoming increasingly popular due to its effectiveness. But you need to pay attention to some moments, one of which is a layer of application. If it is up to 10 millimeters, the use of reinforcement is not required. If this thickness increases, then definitely not to do without supplement.
Today there are enough proposals on the market, for this reason it is not always easy to choose the desired one. To make the choice quickly, it is important to take into account the characteristics. For them, every person builds a choice and makes a decision that will be effective. If there is no experience, it is best to consult with masters or explore such information.
To create reinforcing material, manufacturers use a variety of components:
Depending on the building process, a choice is made. Do not overpay, as each type will have its price, if there is no need. So before choosing you need to understand that each of them represents.
Today it is used often, because it is characterized by ease of use. This is a canvas with small cells created from fiberglass. The plaster on the grid of this species is most often performed inside any room. Although in some cases it happens that it is used outside.
Experts allocate one major advantage - no need to level the wall before starting work. This canopy is attached to any surface, and plastering begins. Most often, it appears a gypsum finish. Since the work as a result is simple, a person can take for it without experience.
Today plastic is present everywhere, and in the finishing of the premises it is not uncommon. Plaster on the grid of polymers is quick and convenient. The fact is that such protection is reliable and comparable to metallic, but at a price several times lower. It is the cost today is the main stumbling block.
The main plus is that the design does not receive a large load, but the reliability is not reduced. In construction stores there is always such a grid with various cells and thickness. When it is applied, you can easily leve out the walls with a large deflection, about 20 millimeters. Plaster on the grid of this format is a relatively easy process.
The most common option for today is a metal mesh. Because when there are big differences and cuts on the surface, without it, it's just not to do. But most often plaster facades on the grid. And for efficiency, the mixture is made from cement. For sale everyone will find several major modifications:
These are the main species that are easy to find on the market. But before starting it is to make a decision that you need. The use of metal allows you to increase the carrying capacity and make a solid finish. Therefore, this method is considered the most common and qualitative. Work with each grid implies its stages and rules. Fastening specific, depending on the material selected.
As already noted, such a grid is lightweight and for it does not need to apply a special type of fixation - a solution is quite suitable. That it turned out neatly and smoothly, it slightly presses the spatula. For the convenience of operation, the grid is cut into strips, but in the laying between them it is nesting. If the site has an extraordinary surface, you can use any fasteners for reliability. But after completing the plaster should not be written. During finishing wooden design Latches can be brackets from a construction stapler.
The polymer compositions are most often attached in the same way as fiberglass, because they have almost the same thickness. If this is not enough, it is quite possible to cope with self-draws. Also be sure to go in places of docking bands. The procedure is simple, but you should not skip some little things.
Metal grid is used most often when you need to create a large layer of plaster. It is for this reason that it is important to securely secure the entire foundation. Only after that the implementation technology begins:
An important feature is that it is necessary to achieve maximum tension without saving material. If the emptiness is formed in the plaster, it reduces its bearing abilities and is lost its entire meaning. The whole process of fixing the grid is simple, but you can not miss anything. Each person without the experience of applying plaster cope with this procedure in a short time. But before starting it is worth stocking all necessary.
Without them can not do. When the grid is selected and located on the working surface, it is worth installing lighthouses, so to speak guides for the rule. It turns out to make a layer as smooth and monolith. To make a rule, you need to take a small segment of metal products up to one and a half meters in size so that it is convenient to move it. Lighthouses are fixed by plaster or any solution in operation. But the guides must be exhibited strictly in terms of level.
According to the masters, if there is a grid of any design, then plastering usually occurs in two layers, although many experts increase this application to three.
Everyone must make a decision depending on the state of the surface. But the order is always united and it should be adhered to:
This plaster completed. So that the surface of the treated area turned out to be neat, it is worth producing an finishing grout. The composition takes a more liquid. Such manipulations will not make difficulties for anyone.
So, we found out how plaster walls are done on the grid. As you can see, materials can be different. But the technology of plaster on the grid is approximately the same.
