To fix a damaged or cracked corner of a wall, you can start by removing any loose debris and applying a layer of joint compound to fill in the crack. Smooth it out with a putty knife, let it dry, and sand it down. Then, apply a second coat if needed, sand again, and paint over the repaired area to match the rest of the wall.
