Grout is performed.
Cracks are covered with a solution with which the surface was plastered. Before swinging the crack, it should be well moistened or treated with a penetrating primer. The grinding is carried out as far as possible from the edge of the old plaster. If the old plaster needs to be grinded, then its surface should either be moistened well or rinse. With the help of a grinding on the surface of the old plaster, a new, thin film of the solution is created, closing all defects and aligning minor irregularities. The rewinding is carried out only by the solution.
