8 Best Mildew Resistant Paints 2025 in the United States

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 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 Zinsser 2770 PERMA-WHITE Mold & Mildew Proof Interior Paint is specifically crafted for indoor use, offering strong mildew resistance thanks to its built-in mildewcide. This protection lasts up to five years, making it a reliable option for areas prone to mold and mildew growth, like bathrooms and kitchens. Being a water-based paint, it is easy to work with and clean up.

The eggshell white finish provides a subtle sheen that is both durable and washable, which is great for maintaining a clean look over time. One of its standout features is the extensive coverage of up to 2000 sq. ft., making it a cost-effective choice for larger spaces. Additionally, the paint’s low VOC levels make it a safer option for indoor environments, reducing concerns about harmful fumes during application and drying. It dries relatively quickly, allowing you to complete your painting projects efficiently.

However, the paint is quite heavy, with the 5-gallon can weighing over 60 pounds, which might be cumbersome to handle for some users. The price point may be a bit higher compared to other interior paints, but the long-term durability and mildew resistance can justify the investment. This paint is ideal for anyone needing a durable, mildew-resistant solution for their interior spaces, with excellent coverage and a user-friendly application process.
