  1. Scrape and prime the damaged area

    Scrape the crack and the surrounding sheetrock with a putty knife. If the sheetrock is covered in gloss paint, cover the crack with drywall primer.

  2. Apply drywall tape and joint compound

    Cover the crack with a strip of fiberglass drywall tape. Use a 4-inch drywall knife to spread a thin layer of joint compound over the tape. Smooth the compound with the knife, and let it dry overnight. The following morning, apply a second coat of joint compound with an 8-inch knife. When the second coat is dry, use a 10-inch drywall knife to apply a third coat. Let it dry overnight, and then inspect the repair. If the surface is not completely smooth, apply a fourth coat of joint compound.

  3. Prime and paint the repaired area

    Use a paint roller to spread primer over the repaired area, and let it dry according to the manufacturer's instructions. Cover the dried primer with paint.
