Maintaining a busy household amid the chaos of daily life can be challenging. Even the most careful family occasionally cuts a corner too close or bumps into a wall, resulting in chips and dings in the plaster. Corners and edges seem to get the most abuse, and on corners the damage is especially noticeable. Fortunately, you can repair chipped plaster and fill wall dings in a matter of minutes.
Spread a drop cloth beneath the chipped area. Use a putty knife or utility knife to gently scrape away any loose plaster around the dinged section of wall, and then wipe the area down with a damp sponge.
Spread the joint compound into the chipped area with a putty knife until it is level with the wall surface. Feather the edges so that the patch blends in with the rest of the wall. On a corner, make sure you feather out to both sides.
Let the joint compound dry completely, according to the manufacturer's guidelines.
Sand the dry compound with 120-grit sandpaper until it is smooth and flush with the surrounding wall. Wipe the dust away with a slightly damp sponge.
Prime the patch and the wall around it. Let the primer dry and then paint it to match the rest of the wall. If you have dark paint, you may need to apply more than one coat.
