Plasterboard plaster with their own hands, in which cases is it carried out?

Plaster of walls from plasterboard, and whether it is necessary?

Plastering on gypsum boards is a painstaking process and not always effective. For example, if the wall is made of cheap material that is not resistant to moisture, sooner or later the surface will crack and deform. Therefore, it is important to cover plaster only moisture-resistant quality plasterboard, really in need of finishing( in the presence of irregularities and potholes).It is also necessary to use special primers.

If is supposed to be decorative plaster of walls( not as the main coating), then a similar finish method is acceptable. To do this, it is important to apply it in a thin layer with a clear observance of the technology, which we describe below. In the process of using all sorts of decorative plasters, simulating this or that surface.

In what cases is plaster applied to plasterboard?

If the walls have small dents and potholes , as well as some irregularities, they are first sealed with putty, and then a thin layer of plaster is applied. In this case, it is permissible. If, on the other hand, the walls have large dents, displacements and curvatures, then the surface finish of the plaster will not solve the problem and will even exacerbate. Large curvatures are corrected by remounting plasterboard sheets.

Also, as already mentioned, it is possible to apply decorative plaster , as it has a composition that provides rapid polymerization and drying. Plus, everything is applied in a thin layer. Therefore, when it is applied to the plasterboard wall, there are no negative effects.

Technique for plastering

If you still understand that painting can not be avoided, then the application should be done according to the rules. Pre-clean the surface of the dust formed during the installation of plates. Most often, an industrial vacuum cleaner is used, but if it does not, then you can use any improvised means( rags, slightly soaked in water).At the second stage, they begin to apply shpatlevke irregularities, joints and seams.

In this case, the mortar for plaster walls can be prepared from both dry mixes and ready-made liquid is taken. It is worth remembering that the dry composition must be diluted with water immediately before starting work. Initially, fillings fill small grooves and seams. After it hardens in these places, begin to cover the wall with an equalizing layer. Then the base is primed( as preparation for plastering).For this purpose, special primer solutions are selected for this material.

An example is an acrylic primer( Tiefgrund LF).They penetrate deeply into the surface, quickly dry out and strengthen it well. In addition, they also provide excellent adhesion to subsequent finishing with plaster. This process is best shown on video, plasterboard plaster in which is carried out by all rules. After watching these video lessons, you will have a clear idea of ​​the technique.

Note! All of the above work should be carried out in the appropriate conditions - at a temperature of + 5 ° to + 35 ° C and moderate air humidity. Also it is necessary to observe precautions: wear rubber gloves and preferably a gauze bandage. After the performed procedures, the tools are thoroughly washed with water, the materials are tightly closed in jars and stored in a dry room.
