Painting Moldy Bathroom Walls
If you have mold growing on your bathroom walls use a 10% bleach solution to clean them and let them thoroughly dry before painting.
When choosing paint use a base coat primer of mildew resistant paint that is oil based such as Kilz. For your top coat you’ll also want to use a mildew resistant paint in egg shell or satin finish for walls such as Behr Ultra.
Pick paint with minimum sheen because it is more durable and if you need to wash dirty fingerprints or smears it is more scrubbable, but do not use flat paint as it will soak up and hold moisture.
