How to Repair Plaster Chips on Corners, Edges & Walls

Updated August 08, 2018

Maintaining a home amid the chaos of daily life can be a challenge. 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, it's not hard to repair plaster chips and fill wall dings. You can fix them in a matter of minutes.

Spread your dust sheet beneath the chip. Use a putty knife or utility knife to gently scrape away any loose plaster around the chipped part, and then wipe the area down with a damp sponge.

Spread the joint compound into the chip 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, it may take more than one coat.

Tip

Use a vacuum or broom to sweep up any dust or plaster particles between each step. If you don't have matching paint, pry out a chip and take it to your local home improvement store to be matched.

Warning

Always wear a dust mask when sanding. Do not use Durabond on painted surfaces; it won't adhere properly.
