Plastering a wall is a simple process, but sometimes there is a risk of the mixture running off. It is in such a situation that a reinforced mesh cannot be dispensed with. Although the question often arises whether there is a need for it. To make a quality and reliable finish, this is the best solution.
The plaster on the grid falls into the cells and no longer flows down. When such a coating hardens, it turns out reliably and durable. According to the masters, this method is becoming more and more popular because of its effectiveness. But you need to pay attention to some points, one of which is the application layer. If it is up to 10 millimeters, then the use of reinforcement is not required. If this thickness increases, then you definitely cannot do without the addition.
Which grid to choose?
Today there are enough offers on the market, for this reason it is not always easy to find the right one. To make a choice quickly, it is important to consider the characteristics. According to them, each person builds a choice and decides what will happen.effective. If there is no experience, then it is better to consult with the masters or study similar information.
To create a reinforcing material, manufacturers use a variety of components:
- Fiberglass. A unique modern composition that allows you to work with a small layer of plaster, making it as reliable as possible.
- Polymers. It is a plastic that is used in many industries today. It shows itself as one of the most reliable, but at the same time does not weigh down the entire structure and is inexpensive.
- Metal. This is a classic that has been in demand on the market for many years. But at the same time, the metal mesh, the price of which is high (90 rubles per square meter), does not lose its leading position.
Depending on the construction process, a choice is made. It is not worth overpaying, as each type will have a price if it is not necessary. So before choosing, you need to understand what each of them represents.
Fiberglass
Today it is used often, because it is easy to use. This is a canvas with small cells, created from fiberglass. Plaster on a grid of this type is most often performed inside any room. Although in some cases it happens that they are used outside.
Specialists point out one main advantage - there is no need to level the walls before starting work. Such a canvas is attached to any surface, and plastering begins. Most often, a plaster finish appears on it. Asin the end, the work turns out to be simple, a person without experience can take it on.
Polymers
Today, plastic is everywhere, and it is not uncommon in interior decoration. Polymer mesh plastering is fast and convenient. The fact is that such protection turns out to be reliable and comparable to metal, but at a price several times lower. It is the cost today that 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 hardware stores there is always such a grid with different cells and thickness. When it is applied, it is possible to easily level walls with a large deflection, up to about 20 millimeters. Plastering on a grid of this format is a relatively easy process.
Metal
The most common option today is a metal mesh. Because when there are large drops and holes on the surface, you simply cannot do without it. But the most common is the plastering of facades on a grid. And for efficiency, the mixture is made from cement. On sale everyone will find several basic modifications:
- Application of thin wire, done by woven system. Such grids are effective both inside and outside any room. Basically, the cell dimensions of such a grid are 10 x 10 mm. The plaster mesh 10 x 10 is fixed easier than any other, because it is not very rigid. But during operation, it shows itself as one of the reliable elements in the decoration.
- Netting - it is wicker-reinforced. Pricemetal mesh - up to 200 rubles per square meter. It is often used not only in decoration, but also in any other construction processes. Works well in large areas. She has the size of one cell in standard terms slightly larger than the first (20 x 20 millimeters).
- There is another mesh manufacturing system - this is the welding of individual rods of various thicknesses. The application is extensive - they are mainly used to ensure that buildings or any structures do not precipitate during operation. Cells can have different sizes (the most popular is a plaster mesh 10 x 10 mm). Everyone chooses the right one depending on the type of work.
- Expanded fittings. It is created using a special technology, which gives it maximum strength. For this, a special machine is used, on which a metal sheet is stretched. In the process, cells of equal size are formed. As a result, the grid for plaster of this sample withstands a thick layer of plaster, and also gives strength to the created structure.
These are the main types that are easy to find on the market. But before you start, you need to decide what you need. The use of metal allows you to increase the bearing capacity and make the finish durable. Therefore, this method is considered the most common and high-quality. Working with each grid implies its own stages and rules. Mounting specific, depending on the selected material.
Fiberglass applications
As already noted, such a mesh is light and it does not need to use a special type of fixation for it - it is quite suitablesolution. To make it neat and even, it is slightly pressed with a spatula. For convenience, the mesh is cut into strips, but when laying, an overlap is made between them. If the site has an extraordinary surface, then any fasteners can be used for reliability. But after plastering they should not stick out. When finishing a wooden structure, the latches can be staples from a construction stapler.
Using other types
Polymer compounds are most often attached in the same way as fiberglass, because they have almost the same thickness. If this is not enough, then it is quite possible to cope with self-tapping screws. It is also necessary to overlap at the junction of the strips. The procedure is simple, but you should not skip a few little things.
Metal mesh 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 fix the entire base. Only after that, plastering work begins. Execution Technology:
- Before starting, the grid is divided into the desired sheets. In this process, do not forget that the junction is overlapped.
- If the mesh itself for plastering is not new, then rust is removed from it.
- When the thickness is small, the cut is made with metal scissors. In another case, a grinder is used.
- For reliability, fixation is carried out with dowels, but before starting, places are marked and holes are drilled. When the wall is concrete or brick, then without a perforatorget by.
- Better start from any top corner. Gradually, fixing the mesh under the plaster, fasteners are used on the working surface.
- But there is one feature - the fit of the reinforcement should not be tight. There is always a gap left. This method gives the wall greater strength and reliability.
An important feature is that you need to achieve maximum tension without sagging of the material. If voids are formed in the plaster, this reduces its bearing capacity and all meaning is lost. The whole process of fixing the grid is simple, but you can’t skip anything. Each person without experience in applying plaster will cope with this procedure in a short time. But before you start, you should stock up on everything you need.
How to place beacons?
You can't do without them. When the grid is selected and located on the working surface, it is worth installing beacons, so to speak, guides for the rule. According to them, it turns out to make the layer as even and monolithic as possible. To make a rule, you need to take a small piece of metal profile up to one and a half meters in size, so that it is convenient to move it. Beacons are fixed with gypsum or any mortar that is in use. But the guides must be set strictly according to the level.
How is the finishing process going on?
According to the masters, if there is a mesh of any design, then plastering usually occurs in two layers, although many experts increase this application to three.
Everyone must make his own decision depending on the state of the surface. But the order is always the same and should be followed:
- Applying the first layer is not difficult, because you just need to throw on the plaster. This requires a craftsman. The composition is taken on it and applied to the wall with a sharp movement. To do this, the mixture should not be too thick. Thanks to this process, the layer is as strong as possible.
- As soon as the first one begins to dry out, you can start applying the second one. It should already be kneading tighter like dough.
- All work is done from the bottom up. After that, they begin to stretch the rule over the entire area, slightly shifting from side to side. This allows you to make the entire surface more even.
- But the third layer is done as needed. It is necessary to visually assess the surface - if something went wrong, then you can make a third application, but already thinner, just to even out the errors. Plastering technology is simple.
- When this is done, the beacons are removed, and the holes from them are smeared with the same compound.
Finish
This completes the plastering. In order for the surface of the treated area to be neat, it is worth making a finishing grout. The composition is taken more liquid. Such manipulations will not be difficult for anyone.
Conclusion
So, we figured out how to make plaster walls on a grid. As you can see, the materials can be different. Butmesh plastering technology is approximately the same.
