How to Repair an Outside Wall Corner

So the best possible solution is to repair it thoroughly. This simple activity does not require any special construction skills as anyone can repair their outside wall corner within few hours, using some simple tools.

Cut the external damaged wall corner
Use a putty knife to do away with any wobbly material from the surface of the damaged wall corner. Now mark the affected area with a hacksaw and cut it in the vertical direction, using a taping or utility knife. Once you cut the damaged wall, use pry bar or screwdriver to remove all the screws or nails holding the plaster of wall in place – if any.

Install new corner bead
Install a good quality corner bead to avoid any kind of damages in future. Corner beads are available in the market in various shapes and sizes; select them according to your requirement and size of the damaged wall. Temporarily fasten one of the edges of the corner bead with the help of some drywall nails or screws. Now align the center of the corner with the attached corner bead and drive some more drywall nail into it. Carefully drive the inserted nails or screws flush with the surface of the wall of your house.
