With high humidity, mould and mildew stains can appear on walls and ceilings.
If this problem is recurrent, it is essential to diagnose the causes of this excessive humidity and to implement an appropriate treatment by calling a professional.
Once the appropriate treatment has been implemented, and the humidity problems have been solved, it is simple to remove the mould stains on a wall. To do this, you must consider the type of coating (paint, wallpaper, wood …).
Here are the materials and steps to remove mould stains.
Tips to fight against humidity in a room
– Be sure to air the room long enough to purify the air and remove moisture.
– Check that the ventilation system is working correctly and that the vents are not clogged. If necessary, disassemble and clean them.
– Try to find out where the moisture is coming from (rising damp, leaks, infiltration…) to treat the cause and prevent the stains from reappearing.
– Avoid using bleach-based detergents that are not recommended for mould. It is best to use a fragrance-free detergent.
Wear gloves and a dust mask to avoid breathing in mould, which can be harmful to your health.
1. Clean drywall
– Dilute baking soda in water.
Soak a cloth, wring it out well, and gently rub the surface.

– Wipe with a dry cloth and let the holder dry.
2. Clean a washable surface
If it is a paint (glycerol type) or a wallpaper (vinyl type) washable:
– Put a little detergent in water.
– Scrub with a damp sponge until the stains disappear.
– Rinse with clean water.
– Wipe well with a dry cloth. Let dry.
3. Cleaning a non-leachable surface
If it is a non-leachable paint (such as matte acrylic or natural paint) or standard wallpaper:
– Brush the surface with a vacuum cleaner.
– With a damp cloth dipped in a bit of water and detergent, then wrung out well, clean the surface.
