How to Repair a Drywall Seam

Fix drywall mistakes like a pro.

Drywall (sheetrock) is the most commonly used interior wall material because it is relatively easy to install and creates a smooth, uniform wall surface. Sheetrock is low-maintenance and durable; holes and improper installation account for the bulk of problems. Holes occur between studs where no support exists to resist impact. Installation-related issues usually happen at seams, where two boards meet. Repairing a seam is a simple task, requiring minimal skill and material, though, if you are not careful, it can get messy.

Things You'll Need

• Sheetrock tape
• 6-inch sheetrock knife
• 10-inch sheetrock knife
• Joint compound
• Sandpaper
• Dust mask

Instructions

1. Rip the existing tape from the damaged seam, and clean out any crumbled sheetrock.

2. Apply a coat of joint compound along the damaged seam using the 6-inch knife. Center a piece of sheetrock tape on the seam, and immediately press the tape into the compound along the length of the repair. Let joint compound dry overnight.

3. Apply a thin finish coat of compound using the 10-inch sheetrock knife. Sand (smooth) with sandpaper after the compound dries. Wear a dust mask while sanding.

4. Prime and paint.
