8 Best Mildew Resistant Paints 2025 in the United States

The Zinsser 276087 Mold Killing Primer is a water-based primer that stands out due to its ability to paint directly over mold, effectively killing existing mold, mildew, and odor-causing bacteria. It is versatile for both interior and exterior use, making it suitable for various surfaces like masonry and metal.

The product is also EPA registered, providing an extra layer of assurance regarding its effectiveness and safety. With a matte finish, it dries with a subtle sheen that can be easily painted over with a topcoat if desired. Each pack contains 32 fluid ounces, which should provide ample coverage for small to medium-sized projects.

One notable feature is its ability to bind chalky surfaces, making it a good primer for older, weathered surfaces. The product is particularly beneficial for users dealing with persistent mold issues in their homes or properties, providing an effective solution to prevent future growth.

The Rust-Oleum Zinsser 287512 Molding Blocking Spray Primer is a solid choice for those needing mildew-resistant paint. One of its standout features is its EPA registration, which assures it effectively blocks existing mold, mildew, and odor-causing bacteria without requiring extensive pre-cleaning. This makes it a very user-friendly option. Additionally, its low odor and water-based formula make cleanup easy with just soap and water, which is a convenient feature for any DIY project.

The primer covers between 8-10 sq. ft. per can and dries to the touch in just 5 minutes, allowing for recoating within 30 minutes. This quick drying time is ideal for projects that need to be completed swiftly. It’s also versatile, working well under any topcoat, but is particularly recommended with ZINSSER Perma-White. It performs well on various surfaces like masonry and metal, binding well to chalky siding and even metal surfaces.

The matte finish might appeal to those looking for a non-shiny look. However, the coverage area per can might be considered limited for larger projects, meaning multiple cans might be necessary. Additionally, while it’s efficient for small indoor projects, the aerosol form might not be suitable for larger areas compared to traditional paint cans. Despite this, its low VOC level is a bonus, making it a safer choice for indoor use. In summary, this product is highly suitable for small-scale indoor projects needing quick and effective mold and mildew resistance.

The Zinsser 02774 PERMA-WHITE Mold & Mildew Proof Interior Paint stands out for its strong mildew resistance, making it a great choice for damp indoor environments like bathrooms and kitchens. The paint film is guaranteed to be mold and mildew-proof for five years, which provides peace of mind and reduces maintenance needs. Additionally, it is self-priming, eliminating the need for sanding and simplifying the application process. The finish is eggshell, which is both washable and scrubbable with soap and water, adding to its durability and ease of cleaning.

This paint is a water-based watercolor type, which might not be as durable as oil-based options for high-traffic areas. It has a flat finish, which might not appeal to those looking for a more glossy look. The coverage is fairly standard at 300-400 sq./ft. per gallon, but it may require more coats for darker surfaces. The drying time is relatively quick at 2 hours, which is convenient for faster project completion.

The paint contains mildewcide to prevent the growth of mold and mildew on the paint film, but it is important to note that this protection is only on the paint's surface and won't address underlying moisture issues. For those looking for an easy-to-apply, mildew-resistant paint for indoor use with a durable and cleanable finish, Zinsser 02774 is a solid option. Its suitability for specific applications should be considered, especially if a glossy finish or high durability is necessary.
