Gypsum plaster - an irreplaceable finishing material

Despite the rapid development of science in the field of building materials, gypsum plaster, which people have used for a long time, does not give up its position. The field of its application remains rather wide. It is based on astringent gypsum substances. It is used for finishing works in household premises (without high humidity) for leveling horizontal, vertical and other surfaces. It is used as a basis for applying finishing putty or decorative finishing.

Plaster universal plaster is used for finishing office, retail and residential premises. The use of this material makes it possible to obtain an excellent surface quality, which, if not excluding shpaklevochnye work, it minimizes them. After finishing with this plaster, the surfaces of walls and ceilings are practically ready for applying decorative coatings, such as structural or smooth paints, wallpaper, decorative plasters. This material provides high adhesion with various decorative materials. In this case, the occurrence of cracks in the gypsum layer is extremely rare.

In comparison with other types of finishing materials intended for surface treatment, gypsum plaster has the following advantages: it combines in one step the work on plastering (leveling of surfaces) and preparation for the application of finishing decorative coatings (putty); Allows for a single application to level the surface with fairly thick layers (up to 10 cm) without risk of cracking or peeling; Its specific gravity is 2.5 r. Less than that of cement plaster.

Gypsum plaster is non-shrinkable, so there are no cracks in it. Solutions from it have a high plasticity and mobility, which provides increased labor productivity. For one shift an employee can perform up to 25 sq. M. With manual application method, and with a mechanized method up to 50 sq. M. Plasters.

Gypsum plaster is ideal for leveling ceilings and other horizontal surfaces. Since this material is porous, it allows the moisture or moisture in the room or room to be absorbed without hindrance, which creates a natural ventilation of the finishing layer and building structures. Thus, a balanced microclimate is created in rooms with such a decoration.

Unlike cement coatings, gypsum plaster has a lower coefficient of sound and heat conductivity. This finishing material is the most suitable for the mechanical method of application. In combination with various priming materials, it is able to solve the problem of plastering concrete surfaces and those that have smooth substrates, without the use of reinforcing mesh. Gypsum plasters can also be used on some soft substrates. When using them, there is no risk of detachment.

Plaster of plaster hand application is intended only for application by hand tools. Usually this method of decoration is used in small rooms. There is another kind of this finishing material - plaster universal plaster. It can also be used for mechanized application by means of special aggregates on large areas of surfaces.

There are many varieties of gypsum plaster from different manufacturers. Virtually all of them are environmentally friendly. Before application on the surface, dry mixtures are diluted with water. The solution is used for an hour. Its average consumption is 1 kg / sq. M. (With a layer of 1 mm). Dry gypsum mixtures are sold, as a rule, in paper bags of different masses.
