Which plaster to use to get rid of dampness in walls?

Damp walls are one of the most common problems encountered in homes, especially on the ground floor or in basements. Beyond the unsightly appearance, dampness affects health, promotes mold growth, and deteriorates the building's structure. Choosing a special plaster is essential to stop the problem and protect the walls long-term.

Why do walls get damp and crumble?

1. Water from the ground rises through the foundation

If the foundation is not correctly insulated, the walls "draw" water from the soil through the phenomenon of capillarity, similar to a sponge absorbing water from a puddle. This is the most frequent cause of dampness on the ground floor.

2. Infiltration from the exterior

Rain or melted snow penetrates through cracks, cracked plaster, or uninsulated exterior walls, leading to visible damp patches inside.

3. Condensation inside

Bathrooms and kitchens produce steam which, without good ventilation, condenses on walls. Over time, stains, peeling paint, and mold appear.

4. Broken or cracked pipes

Water or sewage pipes can leak liquid into walls, sometimes without direct visible signs. This generates constant dampness and progressive damage.
