The whole thing is to tackle these moisture problems as soon as possible, as soon as you see the first spots appear on the walls.
Treat the cause before the symptom

Once it finds its way, it extends by capillarity and can literally require you very important renovation work, such as when facing water damage.
Saltpeter: Your enemy number 1
Have you seen mold, even thin and imperceptible? Saltpeter can grow on the surface of the walls when the walls are not dry. If you notice moisture and stains at ground level, your home may be absorbed (rising moisture).
If spots appear in the corners or behind the furniture, your home is not only damp but may lack light and air. These two factors are very often the cause of a humidity problem in the home or apartment. By evaporating, water can also create condensation in a poorly ventilated area.
Whatever the cause of the arrival of water and moisture, be aware that nothing disappears on its own. The problem must therefore be addressed in depth. Saltpeter often appears in the form of a white powder with small crystals. The salt present in water in the natural state crystallizes and creates these concretions. If mold can be removed, sometimes saltpeter is a foolproof sign of a much larger moisture problem in the wall.
