Mold in an office building in Madison, IN

Mold sealant is a paint-like substance designed to seal a moldy surface from which the mold cannot be fully removed, like wood. Encapsulating mold in this way is generally only done when the moldy material cannot be removed and replaced. Most of the time, it’s better to remove the moldy material if it cannot be adequately cleaned.

What is a Sealant?

Sealant resembles paint (or it can be clear as in the picture above) and it can be applied with a paint brush, paint roller or sprayer. However, unlike regular paint, it contains antimicrobial ingredients that help fight mold. It also seals in any mold remaining on a material, like wood, so that it cannot continue to grow and spread. This process is known as encapsulation.

It’s important to understand that regular paint will not have the same effect. It will just cover up any remaining mold, making it more difficult to see the mold when it begins to grow and spread. It will make the situation worse in the long run.
