Ground OnlyOutlast Mold-Buster is for Exterior and Interior Coatings. Stops mold, mildew, and algae growth on paints, stains, coatings, and adhesives. Outlast® Mold-Buster™ Additive is an EPA-registered product. Its active ingredient is IPBC (3-iodo-2-propynyl butylcarbamate), a broad-spectrum fungicide with a distinguished history of use. Although a primary use is as a preservative for paints and coatings, it is also used in industrial fluids, plastics, textiles, inks, HVAC ducts, and cosmetic and personal care products. There are more than 50 registered pesticide products containing IPBC. 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 water-based coatings, Mold-Buster should still be working hard to protect the paint film after 3 years or more. Made in the USA.  Mold-Buster Data |  MSDS 


  • Contains proven fungicide, IPBC
  • Prevents growth of mold, mildew, algae
  • Extends service life of coatings - less frequent cleaning needed
  • Mixes readily with paints and stains
  • Does not affect color or drying time
  • Resists yellowing

Use Outlast® Mold-Buster when additional protection is required to control surface mold, mildew, and algae growth on the coating such as:

  • High humidity climates
  • Lake Homes
  • Shady Areas and North Sides

Mold-Buster will not hurt the environment and is safe when used as directed. DO NOT treat over existing mold, mildew, or algae. Always sanitize the substrate and clean thoroughly before re-coating. Prepare the surface prior to painting by cleaning and scrubbing with water, detergent and bleach as directed by the stain/coating manufacturer's guidelines. You may use a suitable alternative cleansing system such as Outlast® Kleen-Start. Always rinse all soap or cleaning chemical residue thoroughly. Make sure the surface is dry before coating. All visible signs of discoloration should be removed prior to recoating.

Outlast® Mold-Buster can help extend the service life of nearly any coating. Impressive results are achieved when the Additive is used in a combination approach:

  • Eliminate sources of moisture whenever possible. Increase air flow and air circulation.
  • The life of exterior coatings will improve substantially by cutting back shrubbery and overhanging tree limbs.
  • Install gutters to redirect rainwater away from the surface.
  • Interior coatings last longer and stay clean when exhaust fans are functioning properly and air-flow is maximized.


For Protection Against Mold, Mildew, and Algae:
Using 7.5 ounce containers:
Mix entire container into 5 gallons of paint/stain, or measure single gallon doses of 1.5 ounces per gallon according to the measuring mark on the side of the container.
Using all other package sizes:
Measure doses of 1.5 ounces per gallon of paint/stain. MIX THOROUGHLY. Apply coating to the surface as directed by the coating manufacturer. Always follow all recommended surface preparation procedures accurately.
