Was considered earlier that puttying without preliminary primer is impossible. However in fact it not absolutely so. It is necessary to know only in what cases it is possible.
The answer to this question is ambiguous. On the one hand, it is possible, but it does not give guarantee that putty will keep well and long, but not to move down layers. Initially primer is necessary for the best coupling of materials. Besides, soil protects also from mold, and now it is important as the mold began to appear practically in any house.
But there are several nuances which allow to do without primer. For example, on recently zashtukaturenny cement slurry if dusty works indoors were not carried out, it is possible to putty safely at once.
Priming coat – guarantee of longevity of repair – the myth or reality?
In modern sources it is said that it is impossible to do without priming coat in any way. It is better also for you, you should not redo repair in several years (and in certain cases in several months), and for surface which will not absorb putty.
It is known that primer and putty of surface are basis of all finishing work and additional guarantee of durability of repair.
Irrespective of of what material the surface is made, from metal, concrete, tree or gypsum cardboard, the priming coat is simply necessary for the best coupling with finishing materials. It is possible and not to be troubled by priming works, but the quality of finishing then will be lower, and over time plaster will begin to be showered, and wall-paper to come unstuck. Agree, it not what you expect from repair.
Primer was applied in Ancient Greece, it was used in works of art for coupling of paint with cloth. With its help the adhesion, that is "sticking" is created.
Soil is used, when it comes to high-quality expensive repair; if you plan temporary finishing, then it is possible to do also without primer.
Spackling works
As soil completely repeats all roughnesses of surface before carrying out the main works it is necessary to execute putty. Regardless of which you have putty, finishing or leveling, any is easily ground, allowing to reach the maximum flatness and smoothness of surface. After priming works putty it is simply obliged to be linked well to surface and to stick, as they say, long to summer.
