The plasterboard sheet has a smooth surface, which is very convenient and easy to paint in any color you like. In this case, there is no need to prepare and process the surface with special compounds, when the finished layer of finishing can be safely applied to the casing. Still, before proceeding with staining with drywall, you should plunge all the joints that to cut these areas with a total level of surface. If the cracks and recesses are left unprocessed, it will be possible to maintain a homogeneous color medium of the entire painted surface. The fact is that the putty is distinguished by a loose structure, and when applying paint on it, a completely different color is obtained, not the same as on the drywall surface. Even the dyed doors of the interior type will be distinguished against the background of the wall, since each design is distinguished by the type of starting raw materials taken for its production, and this also determines the result of finishing work. Although the doors and walls trimmed with paint create a single interior style in the room.
The plasterboard walls are primed with a special composition, which guarantees complete leveling of the surface, masking of all cracks, small defects, chips and other irregularities. The paint will be applied to the primer in an even and thin layer, forming a homogeneous surface. It is not necessary to use clean primer for the sealing of drywall skin. The preparatory layer can be the usual water -based paint. However, it should be remembered that its color is very unstable, since the structure does not tolerate moist and temperature differences.
