Outlast® Mold-Buster™ is an EPA-registered product designed to stop mold, mildew, and algae growth on paints, stains, coatings and adhesives.

Each 7.5 oz. container of Mold-Buster additive treats up to 5 gallons of paint or stain; or, it can be measured out in single gallon doses through the "view finder" strip on the side of the container. It does not alter the color of the coating and its thin viscosity allows easy mixing.

The formulation is freeze-thaw stable, and has low odor and low VOC. Suitable for use in oil and/or water-based coatings, Mold-Buster should still be working hard to protect the paint film after 3 years or more.
