Mildew stains often make an appearance in damp locations,
such as bathrooms and basements. Before painting, you'll
need to eliminate this black, speckled growth to make sure
new coats of paint adhere well.
Test the stains by
washing with some warm water and mild detergent.
Ordinary stains will wash out, but mildew won't. If
the stains don't wash out, gently sand them out with
150-grit sandpaper.
Put on some rubber
gloves and eye protection before you wash walls with
bleach, which will kill the mildew spores. After the
bleach treatment, wash mildew away with some TSP
solution or a phosphate-free substitute, then rinse
the area with clear water. Allow the wall to
completely dry.
