* Secure the bead above and below the damaged area with 11⁄4" 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.
