How to Repair Damaged Drywall From Removing Wallpaper
- 1). Apply a thin, even coat of joint compound over the damaged area using the drywall knife. Press a strip of drywall tape into the compound at any damaged joints or corners. Scrape any excess compound from around the tape and smooth with the knife.
- 2). Allow the coat to dry before applying a second thin coat. Apply a third coat after the second dries.
- 3). Smooth the dried compound by rubbing it back-and-forth with sandpaper.
