In the case of applying several plaster layers, you must definitely wait until the previous layers dry.
After all layers of plaster drying, walls are grinded. The alignment of the surface is carried out by a rubble spatula until the remains of a dry mixture remains on it. Grout is produced in areas in the form of squares, gradually moving along the wall. After completion of work, it is necessary to check the evenness of the surfaces using a level or plumb line, and the absence of small roughnesses with a palm.
