How to Apply Corner Beads to a Knee Wall

Metal Corner Bead

• 1

  Measure the length of the corner to be covered, and cut a strip of corner bead to fit using tin snips or scissors.

• 2

  Knock any loose drywall from the seam between the two boards; loose particles will cause lumps and prevent a smooth finish.

• 3

  Lay the corner bead flat against the seam so that half of the bead is on each drywall board. Drive drywall screws with a power drill, at 8-inch intervals, through the holes on each side of the bead to secure it to the knee wall. Repeat for each open seam.
