Don’t Paint or Caulk Over Mold

Painting over mold does not fix the problem—it only hides it temporarily. While fresh paint or caulk might make the surface look better, the mold underneath is still alive and active, continuing to grow and spread.

Why This Matters

Mold grows because of moisture, and if the moisture issue isn’t addressed, painting or caulking over it traps the problem beneath the surface. Over time, the mold will:

• Break through the new paint or caulk, often causing bubbling, discoloration, or peeling.

• Continue releasing spores, even if you can’t see it.

• Create bigger problems, requiring more expensive repairs later.

Covering mold does nothing to remove spores from the air, meaning exposure risks continue.

Common Mistakes to Avoid

• Don’t assume mold is “sealed in” just because it’s painted over.

• Avoid using mold-resistant paints or primers as a quick fix—these are preventative, not a solution for existing mold.

• Never apply new caulk over moldy or damp surfaces—moisture trapped underneath will lead to more mold growth.

What To Do Instead

• Identify and eliminate the moisture source before making any cosmetic fixes.

• Remove or properly clean the mold first—this may require professional remediation if it has spread.

• Use mold-resistant paint or materials only after the area is fully remediated to help prevent future issues.

Painting over mold is like putting a Band-Aid on an infected wound—it may cover the problem for a while, but it won’t stop it from getting worse. Treat the cause, not just the appearance.
