Damaged, wet drywall should be replaced whenever possible. Replacing drywall might be more difficult and expensive, but it’s worth doing to avoid mold growth. It’s especially important to replace wet drywall if it’s in the basement.
Because of the stack effect, the air from the basement flows upward into your home. Due to how harmful mold spores are, you should prioritize replacing basement drywall over repairing them and then focus on waterproofing the basement.
How Moldy Drywall Gets Repaired
If the drywall has mold but it’s not severe enough to require replacing, it can be removed in multiple ways. Even if you have experience removing mold around your house, you might want to leave this one to the professionals. Not only is mold potentially dangerous to deal with (especially if you have a weak immune system), removing surface mold is different from removing mold that is deeply settling into a wall.
Professionals will prepare a strong product that deeply penetrates the drywall. Many times, experts have access to chemicals and substances that are not commercially available due to their toxicity. This allows them to create a professional-grade mold remover that completely cures your drywall of any mold.
Other Repair Methods
If the drywall has a bulging spot or the surface is chipping away, it can often be repaired depending on how much moisture the wall has. If the moisture has remained on the surface, an expert will be able to completely dry out the moisture from the wall.
After that, the damaged parts are removed and a primer is applied. Once that dries, the contractor applies the paint. It’s important to use ceiling paint on drywall instead of wall paint when repairing them: Ceiling paint has special adhesives to better stick on to the material they are applied on.
