Suitable for high-humidity spaces where mildew growth is a concern.

Overview: This satin finish version builds on the same mold- and mildew-resistant protection with a slightly glossier surface for easier cleaning and scrub resistance. It seals porous surfaces and bonds to glossy surfaces without sanding. Fast-drying and low-odor, it’s designed for interior walls and ceilings in damp rooms, basements, and utility spaces. The product is water-based and easy to clean with soap and water, offering a practical option for ongoing maintenance.

Suitable for decks, wood, vinyl siding, drywall, concrete, brick, and other surfaces where mold tends to accumulate. Use proper ventilation and PPE during application. While primarily a stain remover, it complements mold prevention by eliminating visible evidence that can chronically invite regrowth when surfaces are left untreated.
Paint-Guard Mold & Mildew Defense Additive (1 Gallon)
Overview: This water-based additive is poured into paint to create a mold- and mildew-defense film on the painted surface. It’s designed for easy integration with existing paints and extends protection by resisting growth on new coatings. Ideal for walls in damp spaces such as bathrooms and basements where ongoing humidity challenges exist, offering a practical retrofit option for older paint jobs.
MICROBAN Mold & Mildew Paint Additive
Overview: MICROBAN additive blends into oil- or water-based paints and stains, delivering a mildew- and mold-resistant coating. Each 1.5-ounce packet treats one gallon of paint, providing long-lasting protection at the time of application. The additive helps extend the life of the paint film against fungal growth, making it suitable for frequent-humidity areas and high-moisture rooms when integrated into standard paints.
RMR-86 And RMR-141 Bundle (Mold & Mildew Killer)
Overview: This bundle combines two RMR products for comprehensive mold and mildew control. RMR-141 RTU is EPA-registered and designed to kill mold, mildew, bacteria, and viruses while addressing odors. RMR-86 provides rapid stain removal to lift existing marks, helping maintain a clean appearance after treatment. The combination offers both remediation and prevention benefits, suitable for indoor spaces and problem areas with persistent growth.
Buying Guide: Key Purchase Considerations
- Surface type and paint compatibility: For painted walls, mold- and mildew-proof paints (like PERMA-WHITE) offer durable protection. If you’re repainting, consider self-priming formulas to reduce surface prep.
- Scope of use: Choose products that match your goal—prevention (paints and additives) vs. remediation (stain removers, EPA-registered cleaners).
- EPA-registered options: For disinfection and mold removal, look for EPA-registered products such as RMR-141 to ensure regulatory compliance and efficacy online with health guidelines.
- Odor and drying time: Low-odor, fast-drying formulas minimize disruption in living spaces; this is particularly important for bathrooms, kitchens, and bedrooms.
- Surface safety and ventilation: When using cleaners and potent mold removers, ensure proper ventilation and PPE to protect skin and lungs, especially in enclosed spaces.
- Long-term protection vs. immediate results: Paint-based solutions offer long-lasting defense, while sprays and removers address existing stains quickly. A bundled approach can cover both needs.
- Application skill level: Some products require no sanding or minimal prep, while others may demand more surface preparation for optimal adhesion and efficacy.
