FINISHING AN OUTSIDE CORNER

Using Pre-taped Corner Bead

• Measure and cut the corner bead 3/8" shorter than the height of the wall.
• Apply a ¼" coat of drywall compound on both sides of the corner using a 4" knife.
• Firmly embed the pre-taped corner bead into the corner and tight to the ceiling. 
• Wipe off excess compound and feather the edges 2" beyond the paper tape.
• Make sure there are no air bubbles underneath the tape. 
• Allow to dry, then sand lightly, removing any raised or rough areas.
• Apply a second coat using a 6" knife.  Feather the edges 2" beyond the first coat.
• Allow to dry, then sand lightly, removing any raised or rough areas. 
• Repeat with a third coat, using an 8" or 10" knife, if necessary.
• Use a Pole Sander or Hand Sander for sanding.

Using Nail-On Corner Bead
