How to repair mouldy or flaked walls in a few minutes

1. Scrub the stains with a dry toothbrush to remove the larger one.
2. Clean with household alcohol using a soft cloth. This helps to disinfect and stop the spread.
3. Spray a solution of diluted bleach (1 dose of bleach per 99 doses of water). If the wall is very touched, use a more concentrated mixture (1 dose of bleach for 20 doses of water).

Smiling tip: Once the area is well dry, sand lightly with sandpaper, then apply an impermeable primer before repainting. This will prevent the mould from coming back.

Bells on the walls: bubbles that ruin your efforts

Problem: Your paint forms bubbles?

Paint blisters often appear after poorly performed work or due to excessive moisture. Don't panic, you can repair the damage easily.

Repair the blisters step by step:

1. Scratch the blisters with a spatula until a smooth surface is restored.
2. For small blisters, sand out the edges, then apply a suitable primer before repainting.
3. If the blisters are important, remove the affected area completely, allow the wall to dry for several hours, then apply the coating before repainting.

Pro tip: Avoid painting in wet weather. Wait for a dry day and use primer and paint products of the same brand to ensure good adhesion.
