“Using basement paint to waterproof the walls can be a good idea when you are trying to eliminate the possibility of mildew. Basements are usually very dark and musty. Because of this, they can be a great place for mildew and mold to grow. By using waterproof paint, you will help prevent moisture from getting in through the walls. When moisture cannot get in through the walls, mildew will have a very difficult time growing in the basement area. Even if it is still dark in the basement, it will not have the moisture that it needs to grow.”
