Many homes suffer from the problem of moisture appearing on the walls of the house, and this is either due to poor ventilation or lack of ventilation in the house and the lack of sunlight entering it sufficiently, perhaps because it is in the basement, and sometimes because of the presence of a house in a coastal city where the humidity is high, or the place or Cities are generally high in humidity, even if they are landlocked.
1- Indoor humidity: – This type of dampness occurs due to washing, cleaning, bathroom water, mopping floors, and all cleaning methods in which water is used extensively.
2- External moisture: - This type of dampness occurs due to external factors such as weather, as in the case of coastal cities, especially those houses that overlook the water, or because the place is located on a low floor and does not have sufficient ventilation and sun.

This method is considered one of the good ways to isolate moisture as it reflects the heat from the inside and outside according to the temperature. This method is characterized by its low cost and its work to give the walls decoration and Good view, with high physical capabilities. Walls can be insulated by lining them with colored ceramics, which completely prevents moisture penetration.
2- External insulation: - isolating the walls from the outside, including this method that is appropriate when the house is not attached from the outside to other houses. On all the walls, so that the house from the outside becomes all of stone.
3- Treating the walls: - This method is carried out in the following manner:
• Cracking the surface of the walls threatened by moisture, and thus the internal parts of the wall appear.
• Lining the wall with a layer of foam cement and rock wool, this layer becomes a heat insulator and thus works to isolate moisture.
• Instead of thermal wool and cement, polyurethane or asphalt can be used. It is used to fill the voids in the walls, then re-paint the wall or the oyster and repaint it again. It is also possible before painting to paint the wall with one of the adhesives, which is considered a moisture insulator on the walls.
