Once you are released from the surface of walls of old wallpaper, paint, etc., can go to the plastering. Competently carry out their own calculations and evaluate the material terms of work is difficult, because it is expedient to invite the experts. Ignore expert advice is not worth it, because it depends on the plastering of the most important – the geometry of the room.
For work on plastering the room suitable mixture, which is composed of two kinds of components: the first have inert properties, the second – connecting (it is, for example, gypsum or cement). The dry mixture is diluted with water, resulting in a solution, which cover the walls. While stucco is not solidified, you can create a variety of artistic elements, such as molding or arch, if it is included in the design space. After the coating becomes firm, the walls are ready for finishing work. Drying times depend on the surface properties of the applied solution, the temperature and humidity, as well as from the number of layers applied. If you plan on plastering in several layers, each successive layer is applied over time, if we are using cement – from 2 to 6 hours if gypsum – from 7 to 15 minutes. Consider the types of plaster 1.
