Expert Advice on Home Improvement

Outside corners on walls take a lot of abuse and can become dented and damaged over time. To repair, use a hacksaw to cut through the damaged section of the metal corner bead, then score along the edge of the bead about 1¼” back from the corner. After prying the bead off the wall, cut a new piece of corner to fit, and nail it in place. Apply several coats of joint compound to the repair, allowing adequate drying time between each coat. Sand the joint compound smooth, and prime the repaired section before painting the wall.
