According to its composition, the decorative plaster is divided into the following types:

• Structural plaster is a ready-made dry mix prepared according to factory technologies. Most often, this type of plaster is used in public places where there is no need for excessive originality, for example, facades of apartment houses, walls on staircases, corridors and so on.

It is quite possible for each creative person to apply moisture resistant decorative plaster with his own hands. But it should be remembered that there are several mandatory rules and individual recommendations for each type of decorative plaster. It is necessary to strictly observe the consistency and technology of work with the plaster mixture according to the instruction, that the new coating should have an excellent appearance and function properly for a long time.

The process of finishing with decorative plaster of different working surfaces has its own nuances:

• On different surfaces decorative plaster dries different times. For example, most quickly it dries on concrete surfaces, longer - on wood or metal.
• Concrete walls are pre-leveled with a gypsum mixture. If there are spots on the walls, it is desirable to treat them with white water-based paint.
• Gypsum plasterboard walls must be plastered all over the surface, paying special attention to the joints and corners, and creating an absolutely flat surface.
• Wooden walls are treated with oil paint to prevent deformation of the surfaces.

Before self-applying decorative plaster, remember that before working with the plaster mixtures, you must thoroughly clean and treat the surface. The final result will depend on the quality of the preparation of the walls. The procedure for the preparation of walls:

• Clean the walls from old coatings: wallpaper, paint, whitewash or plaster, rubbing the surface with a spatula or sandpaper. All metal surfaces, in order to avoid the appearance of rust, must be isolated.
• Cracks, chipped, unevenness in the corners carefully closed with a plaster mixture, the surface is leveled.
• Treat the walls with acrylic primer of deep penetration two or three times, otherwise the plaster may lose its texture qualities.
• If the walls are treated in the bathroom, first a layer of waterproofing mixture, for example, sanitizing plaster, should be applied, then apply a primer.
• It is necessary to wait for complete drying of the primed surface, and only after that you can proceed directly to the application of decorative plaster.

Each type of decorative plaster has its own application technology, which is necessarily prescribed by the manufacturer on the package, but there are some general requirements that must be observed regardless of the type of solution:

• The plaster mixture is applied only on a clean and dry surface.
• Plaster mixes must be prepared in small volumes.
• Before applying the mixture it is necessary to test it in a small area: the solution should not be too liquid or thick.
• It is optimal to work with a partner: one person applies a 2-3 mm thick spatula with a spatula and smoothes the trowel, the second immediately forms a decorative surface structure, as the mixture dries very quickly.

Walls with decorative moisture resistant plasters are easy to clean with water and any liquid detergent.

In case of damage, the wall can be tinted and even completely repainted. The elasticity of the material will prevent the appearance of cracks and chips. Due to the fact that antibacterial agents are added to the moistureproof plaster, the possibility of mold is eliminated, so it is enough to simply wipe the walls with a damp cloth from dust.
