Most drywall problems can be remedied with basic dry wall materials and specialty materials: drywall screws; paper joint tape; self-adhesive fiberglass mesh tape; corner bead; all-purpose joint compound; drywall repair patches; scraps of drywall; and drywall repair clips.


To repair a popped nail, drive a drywall screw 2" above or below the nail, so it pulls the panel tight to the framing. Scrape away loose paint or compound, then drive the popped nail
1⁄16" below the surface. Apply three coats of joint compound to cover the holes.

How to Repair Metal Corner Bead

  1. RN668 081ATIFret

    Secure the bead above and below the damaged area with 1 1⁄4" drywall screws. To remove the damaged section, cut through the spine and then the flanges using a hacksaw held parallel to the floor. Remove the damaged section, and scrape away any loose drywall and compound.

    Cut a new corner bead to fit the opening exactly, then align the spine perfectly with the existing piece and secure with drywall screws driven 1⁄4" from the flange edge; alternate sides with each screw to keep the piece straight.

    File the seams with a fine metal file to ensure a smooth transition between pieces. If you can’t easily smooth the seams, cut a new replacement piece and start over. Hide the repair  with three coats of drywall compound.
