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.
Prevention
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.

KILZ Interior/Exterior Basement and Masonry Waterproofing Paint
Safe to use indoors or out, it’s not only mildew-resistant but forms a barrier to stop water infiltration. This helps ward off future mold problems. Apply with a brush, roller or airless sprayer. The paint dries to the touch in one hour and can be re-coated in four.
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.”

Zinsser Mold-Killing Primer
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.
