• Spray. The prepared solution is sprayed using a special spatula. The solution is pounced on the wall so that all defects can be hidden, and the recesses and cracks should be well filled with the solution. The thickness of the layer should be no more than 9 mm for brick walls and no more than 5 mm for walls of concrete or stone. So that the compatibility between the layers is good, the solution does not need to be leveled.
