Purvation of walls is the most commonly used method of internal and external decoration of the room. The popularity of plastering is due to relatively inexpensive materials that are part of the solution, and the simplicity of their use. However, the process of plastering and the subsequent drying of the layer of plaster requires compliance with certain recommendations in order to avoid the formation of cracks. Cracks may appear for a number of reasons. The use of solutions with an excessively high content of astringent materials, or the use of solutions, poorly mixed and heterogeneous in composition, can lead to the appearance of cracks in the plaster. After applying the plaster, it is necessary to ensure the free movement of the warm masses of the air for uniform drying of the solution.
Cold drafts and the use of heating devices can lead to too intense drying the plaster layer and, as a rule, to the formation of cracks. Therefore, at the end of the plastering work, all windows and entrance doors should be tightly closed. You can not apply a thick layer of plaster at one time, and when applied with thin layers, it is necessary to allow the previous layers to dry well. In order to avoid cracks in plaster, it is necessary to strictly observe the proportions of fillers and astringent materials that make up the plaster solution. Before plastering the brick wall, the masonry surface must be pre -moistened with water, then cracks can be avoided.
