Does painting over a mouldy surface take care of the mould problem?
A. Painting over mould only masks the problem. Paint does not kill the mould nor stop if from growing. Surfaces that are washable should be cleaned with a detergent and bleach solution, and then allowed to dry. If you are going to paint, remove any mould first. Then ask yourself why is the mould growing here? Until you fix the problem, it will keep coming back.
