Paint plasterboard, fill with spatulaGypsum plasterboard can be used to suspend ceilings, to install new walls or room dividers, or to remove an attic floor. The advantage of these boards is that they are processed in dry construction.
There is no water used, so they do not need time to dry and also the dirt, which arises in such work, is limited.
Use plasterboard in the house
Gypsum plasterboards always require a substructure to which they are screwed. This can consist of simple wooden slats or metal profiles. This substructure is fixed to the floor, ceiling or wall and provides the necessary stability. Wood is a bit cheaper, but has the disadvantage that it reacts to moisture, which can cause cracks in the walls made of plasterboard. Therefore, for rooms such as kitchen and bathroom, where water vapor often arises, metal profiles are preferable. In other rooms, squared timbers are also well suited for drywall construction.
After all the plasterboard has been fixed to the substructure, the joints and also the holes in which the screws were well sunk are filled with putty. This is important because otherwise, after pasting the panels over with a wallpaper or woodchip, the joints will be visible and give a very unpleasant picture. The
Putty takes some time to cure, then
it is simply ground smooth by hand or with an electric grinder. Cutouts can be inserted into the plates with a simple saw. There, switches or sockets can be used and the necessary electrical wiring can be installed within the substructure.
Gypsum plaster boards are either made from natural gypsum or from the so-called REA gypsum, which are obtained as a by-product in flue gas desulphurisation plants. They are naturally very absorbent, so they must be primed before further processing. Such a deep background is evenly applied to the plates with a roller or a brush. This depth should always be matched to the material with which the new plasterboard wall should later be clad. There are primers for paints and for plasters.
Even with the use of wallpaper and woodchip wallpapering ground can be applied to the plasterboard, thereby it is easier later to solve the wallpaper again from the plasterboard. Without this backing, it is very likely that when peeling off the wallpaper, the top layer of the boards, which is made of cardboard, also peels off. After the primer is cured, the surfaces can be painted, papered or plastered as desired with virtually all commercial colors.
