Step 6: Cover outside corners

• Make sure the metal corner bead on outside corners is nailed or clinched every 10 inches. Straighten bends, if necessary, with corner clincher (see "Tools List").
• Using the 5-inch knife, smear one side of bead with compound. Repeat on the other side.
• Holding the blade against drywall and bead at the same time, run the knife down the corner, smoothing the compound in a single stroke. Repeat on the other side.
• Let compound dry overnight.
