What to Know About Painting Over Mold and Mildew

Musty ground-floor apartments, poorly ventilated bathrooms and dank basement laundry rooms are all potential petri dishes for growing ugly and unhealthy mold and mildew. Interior and exterior paints or primers containing antimicrobial properties can help keep mold under control.

Mold, a form of fungus that produces spores that float through the air, thrives in moist, warm environments. Mold and mildew produce allergens that, when inhaled or touched, can cause allergic reactions and trigger attacks in asthma sufferers. According to the Environmental Protection Agency (EPA), “The best way to control mold growth is to control moisture.”

Here are some useful steps for dealing with mold in and around your home:

  • Find the source of the moisture. Don’t forget to look for hidden leaks in walls and under kitchen cabinets.
  • Clean infested areas with detergent and water.
  • After cleanup, let surfaces dry completely (allow 24 to 48 hours).
  • Repaint the area with a mold-resistant product.


  • Install fans in bathrooms, leave windows open whenever possible, use an exhaust fan when cooking and run dehumidifiers to reduce indoor humidity.
  • Add insulation to windows, pipes and walls to prevent condensation.
  • Maintain gutters and downspouts.

Once you’ve taken care of the moisture problem and cleaned the area, here are some top-rated paints and primers to help keep the mold and mildew from returning.

Rust-Oleum Zinsser PermaWhite Exterior Paint

Rust-Oleum Zinsser PermaWhite Exterior Paint makes preventing mold and mildew growth a no-brainer. It requires no sanding, resists dirt and moisture and cleans up with soap and water.

As one Amazon reviewer wrote, “We had some exterior wall areas that had some mildew and moss. Most of this we washed during prep and scraped, but even so, areas remained discolored. One coat of this paint applied by brush completely covered these areas, and even a few spots that weren’t prepped. Excellent paint and primer in one.”

In some cases, the best remedy for serious mold problems combines a fungicidal primer layer with a topcoat of antimicrobial paint. This two-step process is especially warranted after severe water damage (like from a flood) or when mold has gone unaddressed for some time.

Applying the ready-to-use Zinsser Mold Killing Primer delivers an outstanding protective undercoating on non-porous surfaces. For small projects, use Zinsser Mold Blocking Primer spray.
