Plaster is a certain type of wall cladding, it belongs to one of the cheapest species. Plaster is used to smooth the seams, for insulation, for leveling surfaces – using this material a great many.
Sometimes there is a poorness of plaster, it does not hold on the surface and creates dust, but this happens due to the lack of a lime additive. Lime fills the gaps and gives the solution tightly stick to the surface. If the binder is not enough, then the plaster will begin to crumble and crack.
The fat content of the plaster suggests that it has a lot of astringent, it will also begin to crack sooner or later. It is impossible to close the cracks, you can only redo the surface again. The composition of the internal plaster includes lime, gypsum and cement. All these solutions are used for certain areas and one solution cannot be replaced by another.
If the surface is concrete, then it is impossible to apply a gypsum solution, it will begin to quickly disappear. Gypsum and cement are included in the struggle, which means that the work will not have quality. If electrical work is carried out jointly, then the wires are installed in the wall and the solution is applied on top.
Heating equipment is attached with gypsum solution. If the pipes pass in the walls, then gypsum promotes the appearance of rust, it can be seen even through whitewashing and on the wallpaper. First, one layer of plaster is applied, and after drying the second. Plaster does not dry with heating, otherwise it will crack.
To the plaster dry – it needs carbon dioxide. Often used in the construction of used brick, well -cleaned of previous solutions. Do not use the brick from the furnaces, it deforms the wallpaper and emits the tar and soot that has come into it.
Before applying the solution, the surface must be wet. Be sure to degrease and wipe the surface from dust. If it is impossible to wipe, apply a thin cement layer, and then the main solution. The concrete surface is first made rough, and only then a solution of plaster is applied. The main thing is to comply with the safety rules, because with poor quality work, it will disappear in pieces.
