Purrender of walls is a spraying of a cement mortar and its distribution on the wall surface. .
If the wall has a surface far from perfect, then, most likely, you will need to apply three layers of a cement solution, in which it is recommended to add PVA glue to improve its waterproofing and clutch. .
Purvation of the walls begin with abundant moisture. It is necessary to moisten the wall with water, and then treat the primer. . This layer is performed with a thickness of 3 to 9 mm. When coating a cement of the wall, it is important not to allow gaps.
After the first layer of the cement solution completely dries, the second layer of the solution (soil) is applied to the wall of the second layer. To do this, use a solution of cement with a thicker consistency. The second layer of cement mortar should have a thickness of 15-20 mm. It is during the application of this layer that it is necessary to achieve a completely flat surface. If the optimal option during the first application of cement plaster could not be obtained, the following layers are applied after drying the cement
Having learned the smooth surface, perform the final operation – wall covers. A solution of cement, which should have an average consistency, is applied to the wall with a layer with a thickness of 2 to 4 mm, after which alignment and grouting
