High -quality slope must be mounted for a very long time.
When performing these slopes, it is necessary to apply the plaster not in one layer, while each subsequent will be applied only when it is completely dry. After that, you can proceed to the priming of the surface and paint it. The process of this kind takes about about a week, perhaps even two. The parameter of thermal insulation of slopes from the plaster leaves much to be desired, and if it is very cold outside, the windows will sweat.
