The divorced cement structure very quickly stiffens therefore it is not recommended to dissolve all powder at once.
Plaster has white shade. It is fast dries, does not limit masters in use of decorative finishing. Experts do not recommend it to apply to front works as plaster not really well transfers temperature drops. Material after hardening has the same high strength, as well as cement.
Acrylic mixes are popular. They are convenient in work, safe, have the affordable price. Producers produce dry powder for universal use. Sometimes add anticorrosive, antifungal or fire-prevention components to mix. Polymerization of mix is reached at contact with air. At the same time mix long time remains flexible.

Putty goes on priming coat which is put in the normal way. When liquid soil is applied, it needs to allow to dry out well. Thanks to it there will be film allowing parent material to be absorbed, provide full-fledged adhesion.
It is necessary to putty wall thin layers. If on surface there are dents of the big size, they should not be closed up at once. At first it is recommended to wait for drying of the applied solution, to repeatedly ground, repeat alignment. The number of such approaches can be unlimited.
In rooms with the increased humidity there is probability of formation of the parasitic environment. For the purpose of prevention it is necessary to carry out processing by antiseptics. Experts recommend to cover with primer surface and each layer in two layers. At the same time the direction of brush or the roller has to be perpendicular.
