Plaster mesh is actively used when carrying out the following types of work:
- Wall decoration, both inside the building and on the facade.
- During floor screed.
- When installing soundproof and heat-insulating materials.
- Strengthening surfaces with significant defects.
- During the installation of warm floors.
- During the creation of self-leveling floors.
Important! You can refuse to use a reinforcing mesh only if the plaster layer does not exceed two centimeters. And there are no big cracks on the wall.
There are three main types of plaster mesh:
- Made of plastic.
- Made of metal.
The first two are thin, but strong enough. Fiberglass mesh can be used if the plaster layer does not exceed three centimeters! In addition, it is usually only used when working inside the house. If the plaster layer is more than three centimeters or the work is being carried out on the facade, you should use a more durable, resistant to all external influences mesh made of galvanized steel or polymer coated steel.
In addition, the sizes of the cells are very important when choosing a plaster mesh:
- Small – from 2.5×2.5 to 6×6 millimeters.
- Medium – from 6×6 to 13×15 mm.
- Large – 22×35 mm and more.
The finer the work to be done, the finer the mesh cells! The large one is more often used on facades, and the small one is usually called painting, it is used, for example, at the joints of drywall, to seal small, inconspicuous cracks. Serpyanka belongs to such a grid – a special type, in the form of not a canvas, but a tape, and on a self-adhesive basis.
In addition, such types of construction mesh as masonry, universal, armaflex, plurima, syntaflex are distinguished. The last three varieties are polypropylene, but with different mesh sizes..
A metal, heavier mesh is attached to the facade, to the wall or ceiling with self-tapping screws or dowels. Thin fiberglass mesh and plastic can simply be pressed into the first layer of plaster previously applied to the wall.
On the one hand, there is nothing particularly difficult in using a plaster mesh, but it is very difficult to attach it to the ceiling alone, especially if the mesh is heavy enough.
For clarity, the process of installing the plaster mesh will be presented as a video:
