Our Ceiling Paint, Wall Paint and Trim Paint all have a mildew-resistant finish which helps inhibit the growth of mildew. While the mildew-resistant finish will help keep mildew growth at bay, it will NOT prevent, or fix the growth of mold, mildew, or other fungi. Painted surfaces in high-moisture spaces, such as bathrooms, or homes in excessively humid climates, should have proper ventilation to help avoid mildew and mold.
