How Do You Repair The Drywall In The Bathroom Above The Shower/Bathtub?
The drywall in the bathroom above the shower and bathtub is typically subjected to a daily onslaught of steam. If there’s a lip at the top of the shower stall, water collects there and seeps into the drywall, causing it to soften and crumble. Although the sheetrock used in bathrooms is usually “greenboard,” which has a moisture-resistant coating, it’s not waterproof, and once water seeps into the tiniest crack or gap, it will start crumbling. Fixing bathroom drywall entails making the repair as watertight as possible. Remove softened, crumbling drywall and scrape away peeling paint. If there’s a large area of ruined drywall, cut it out with a utility knife. Scrape away loose caulking along the lip of the stall with a putty knife. Attach at least one furring strip (1-by-3-inch piece of wood) to the back of the existing drywall with 1 5/8-inch drywall screws unless the drywall you’ve removed has exposed at least two wall studs. You will need something solid to attach the new drywall patc
