The damp ascending is one of the most common categories. Usually the effects of the natural evaporation are rings, damp areas and black mold. The progressive crystallization of the salts produces the pores obstruction and weakening of the surfaces; this fact brings the decay and the break up of the plastering. It’s essential to evaluate the nature and the salts solution of the walls.
