At the final stage of finishing work, special importance is attached to such a procedure as alignment of the walls under the decorative plaster. This is explained by the fact that the well-known advantages of this unique coating are able to manifest themselves only when the surfaces of the walls are perfectly prepared for decoration.
At once we will make a reservation that the known methods of preparatory work do not differ significantly from similar activities carried out before painting or pasting walls with wallpaper. In addition, when implementing them, it is not at all necessary to achieve a completely flat wall surface, because, due to its plasticity, the applied material perfectly hides all the irregularities on it.
Sanding the walls after puttying
It should be understood that putting plaster is made only at the final stage of finishing works, when all window and door openings are already installed in their places, and the floor covering chosen by you is completely laid. Surface preparation in this case is performed according to the following scheme:
Sealing of cracks and leveling
In a situation where you are planning to apply a thick layer of plaster with a pronounced structure, putty the surface of the wall is not necessary. But with a relatively thin layer of coating, preparation of a perfectly flat surface should be mandatory. Otherwise, all the irregularities of the base can not be hidden under a layer of decor, and the consumption of the material used will increase markedly.
After completing all the filler operations, you can proceed to sanding the surface of the walls using fine-grained emery paper.
Surface treatment for plaster
Surface treatment is subject to a number of factors:
The primer should be applied according to the following recommendations:
A surface treated in this way will be completely ready for applying a layer of decorative plaster on it.
Special attention should be paid to the smooth transitions between the smooth and texture strips of the coating.
