Many houses experience minor structural problems as they settle over time. Fortunately, repairing a corner bead separating from the rest of the drywall only takes a few materials: drywall compound, drywall mesh tape, drywall nails, a hammer, primer, sandpaper, a straightedge and a taping knife.Continue Reading
Tap the corner bead lightly with the hammer to straighten a bent bead and push it back flush with the wall. Use a few nails to secure it to the stud. Use the straightedge to make sure none of the corner bead sticks out from the wall.
Use the mesh drywall tape over the edge of the corner bead, covering the cracks between it and the drywall. Use the taping knife to spread a coat of drywall compound on one side of the corner bead. Smooth it flat with the edge of the knife. Allow it to dry.
Coat the other side of the corner bead then mesh tape it with drywall compound. Smooth it flush with the wall. Allow it to dry.
Sand both sides, creating a smooth finish flush with the wall. Apply a coat of primer and allow it to dry. If necessary repaint the wall, but make sure it matches the existing color.
