Five Easy Steps to Removing Mould & Mildew from Your Walls


One of the toughest problems that people face before they start painting is how to remove mould and mildew stains from their walls or ceilings. You should never paint over the mildew because it will continue to grow under the paint, and that could cause your new paint to start peeling within a year or two. But don’t get discouraged. Mould and mildew are a common problem in many homes, and there are some simple steps that you can take to solve that problem.

1.) Start by removing all furniture and objects from the room to be painted, or move them to the centre of the room and cover them with a drop cloth. Place a plastic liner and/or tarp on the floor. Put on goggles, long rubber gloves, and you should also wear a facemask for protection.

2) Then clean the wall with mild detergent and water to remove dust and dirt.

3) After the wall is dry make a solution of household chlorine bleach and water by mixing a 62 ml of bleach to 3.79 L of water (four parts water to one part bleach).

4) Wipe wall with the bleach solution and wait at least 15 minutes for it to dry.

5) Apply the bleach solution again if necessary, and rinse with water when finished. (For your safety, never mix bleach with ammonia or other household products that may have ammonia in them, because the mixture can cause dangerous fumes.) You may also use a commercial product like TSP (Tri-sodium phosphate) to remove the mildew.

After the wall is clean and the mould and mildew have been removed, you can start painting.
