A painting mesh is a reinforcing material consisting of cells of various sizes. It is made by pulling molten quartz glass by pulling and used when conducting finishing works. Without a painting mesh, it will not be possible to make high-quality repairs, as it provides reliable fixation of the joints and plaster.

Peculiarities

Shpening is the last stage of finishing works before applying paintwork products. The quality of the work performed depends on how long the repair will serve whether the walls will have an attractive appearance, as well as the strength and fortress of bases. First of all, the shp clashing is produced to give the walls and ceilings of evenness and smoothness, climbing cracks. In this main role plays a painting mesh. She is designed to hold the finish and not to give it to detach. Also, the grid protects against deformation and has a shockproof effect.

The reinforcing grid has such properties:

  • refractory;
  • moisture resistance;
  • well tolerate temperature differences;
  • non-toxicity;
  • Wide range of applications (concrete, fiberboard, chipboard, brick and other materials).

Resistance to the gap depends on the thickness of the material and the size of the cells. The more it is stable, the higher the quality of the material. Modern mesh are produced already impregnated with polyacryl composition.

This is done in order to:

  • maintain material strength;
  • Do not perceive the effects of alkalis;
  • increase the adhesion of the canvas to the surface;
  • Do not break down.

For plastering, painting meshes based on fiberglass or polymers are used because they weigh. They are used in the thickness of the layer of plaster in 2-3 cm, if a thickness is less than 2 cm, then the reinforcement is not necessary, since the layer will be able to hold on. For layers, more than 5 cm paint grids are not suitable, but some experts impose several layers of the reinforcing canvase. The reinforcing material is not enough just to put in the plaster layer, it must be fixed on the surface. Dowels are taken for concrete walls, for wooden – nails or self-tapping screws. This is done so that the plaster does not fall behind the wall due to poor fixation.

There are three types of painting nets that differ in the size of the cells:

  • reinforcing putty;
  • Serpenta;
  • Grid Pautinca.

The reinforcing grid in the main criteria are the size of cells and fiberglass density. If the cells are small, the mesh is soft. When choosing fiberglass, you need to focus on the type of surface. Grid with thick threads suitable for facade finishes, and with thin – for internal. Fiberglass is distinguished by resistance to mechanical loads, temperature differences, high humidity. Also the reinforcing mesh is light, does not succumb to rust. If necessary, as a result, just paint the walls, then this type of grid is well suited. To begin with, it is necessary to completely dispover the surface of the walls using a spacing network. For such a goal, it is better to take a mesh with cell size of about 5×5 mm so that the plaster is better fixed. Cracks should not appear on a highly disparished wall.

Serpentanka also consists of cells of different sizes of square shape, but it most often contains adhesive base. Comes in rolls up to 20 meters, and narrow width. Ideal for fiberboard, chipboard, drywall, cement and other materials. With it, they are eliminated by defects and cracks, the surface of the ceilings is aligned, the walls are becoming smooth. For the reinforcement of the walls of the walls, you can purchase a special corner from the grid that simplifies the task and will help well all wove. Mesh Pautinc (glassball) perfectly suitable for surfaces of a large area, as it is a wide roll. Glass coolers increases the adhesion of plaster, because it is a nonwoven fabric, obtained as a result of crimping. Basically, the cob is used during the reinforcement of the ceilings.

Application

Before using the reinforcing canvase, it is necessary to cut it into fragments, and these fragments already put on the first layer of plaster. It is also important to impose fragments of the Mesh Vansel. The reinforcing canvas stretches along the plaster from the center to the edges. It is important to follow the edges of the canvas so that it does not look.

The process of putty using painting meshes is almost the same for all kinds:

  • It is necessary to primitive the plastered surface;
  • Apply a spacion layer only after complete drying of the plaster;
  • With a spatula, a painting mesh is placed on a low layer of putty;
  • Apply another layer of putty.

When using the sickle to start, it is necessary to clean the joints and primed them, and after drying it is sickle. After all these actions, the second layer of putty and leveled.

There are two ways of superimposing:

  • Fastening the mesh to the surface on which glue is pre-applied. For better fixation, it is necessary to press the sickle to the surface. After the grid attached, you need to apply another layer of glue, and after complete drying to make a putty. This method can reduce the quality of the finish;
  • A spike layer is applied to the surface, the grid is applied to it. Immediately after mounting the grid, you must apply a second layer of putty.

All works are performed with glassballs with a roller. First, the roller is applied glue over the surface, then glassball is applied so that the strips came to each other by 50 mm. To dissolve the grid it is necessary to spend the roller. Before using the grid, the web must be rebounded.

Grinding

After performing all actions on the reinforcement of the walls, it is necessary to carry out the finishing putty and polish the surface. The finish putty is carried out in the same way as the main. The main thing is to wait until the layer with a painting mesh dry, otherwise the coating will not hold. The thickness of the finish putty should be approximately 1-2 mm. After drying, you can move to grinding. Grinding is carried out so that the walls are perfectly smooth and smooth, because the appearance of the premises depends on it. In addition, paint or wallpaper do not hide defects, but emphasize them. When uneven surfaces, wallpapers can be broken or wrinkled. To achieve flatness of walls, grinding spend several times in a well-lit place so that small defects are clearly visible.

After completion of the putty, move to grinding it is impossible earlier than a day, It is necessary to wait until the spike layer is completely dry. For grinding use fine sandpaper or grinding sponge. It is necessary to spend it over the entire surface to remove all the protrusions and irregularities. If there are big depressions, they must be sharpened. When choosing sandpaper, you need to look at her grain. At the very beginning of grinding it is better to use coarse-grained, and at the end to give smoothness – fine-grained sandpaper.

Grinding is carried out in several stages, but technology is the same – rotational movements from top to bottom are treated with small areas of the surface. During the process, the grain of sandpaper is changing. Usually at the last stage use fine-grained sandpaper. For hard-to-reach places, a grinding sponge is used or you can try to fold several times the sandpaper. In addition to sandpaper, you can use an abrasive grid. Its main difference from paper is high wear resistance, it is less clogged with dust, but also higher in price. If there is a grinding machine, the grinding process will greatly accelerate. Especially the quality of work will increase. The machine is also attached to the machine, and the surface is processed.

After grinding walls you need to completely clean all surfaces from dust and dirt. To secure the result of the wall soot once again.
