Treatment of humidity in a cellar

Many poorly ventilated cellars, in addition to being dark and cold, are wet. This last defect which restricts their use, can be fought. But we must first know the causes. Leaks on the collectors are possible. Underground walls without protection let the water seep during heavy rains or deteriorate under the constant humidity. Saltpeter and rust appear.

Humidity and rust in a cellar

Wet wall

1. The lack of aeration of a cellar maintains a permanent moisture that is conducive to the development of saltpetre on the porous materials of the walls (bricks, coated blocks or rough formwork).

2. This moisture and the condensation that can result, attacks the metal parts and objects on which the rust is embedded and over time disintegrates them in plates.

3. To combat this moisture, first seal any leaks in the manifold seals. The leaks of these joints, often minimal, are not very visible but are detected mainly by the spots that they produce on the walls.

Anti-saltpetre treatment

Anti-saltpetre treatment

1. Against saltpeter, remove it by vigorous brushing and then treat the surfaces with a liquid solution containing 10% hydrochloric acid. Take precautions: clothes, mask, gloves, glasses. Then pass the anti-saltpeter to eliminate the nitrifying bacteria and redurcir the wall.

Anti-humidity paint

2. To remove residual moisture from a cellar wall, roll white anti-humidity paint to form a waterproof screen. It blocks moisture, does not blister and prevents infiltration and mold.
