Applying a pure solution in this form is not very nice, because it will be poorly equalized, and it is difficult to rub it on this brick wall. Its applicability can be used using a reference special cone, which is suspended by the rope, and at the very beginning it is sharp, and at the end expanding, it allows you to seize the risks on it itself. If a hollow brick, in its composition, can occupy no more than 7-8 centimeters, then for full brick, this will be 14-16 centimeters.
