  1. Remove the damaged plaster

    Cut around the damaged or peeling plaster with a utility knife. Remove the damaged area. Use sandpaper to smooth any rough edges, wiping away the dust with a damp rag.

  2. Mix the plaster patching compound

    Follow the manufacturer's instructions for mixing the plaster compound. Slowly add water to the compound until it achieves the desired consistency.

  3. Apply the patch

    Using a putty knife, push the plaster compound into the hole. Continue until the hole is filled. Place joint tape over the hole, and cover the tape with a small amount of the plaster compound. Blend the edges into the surrounding wall. Allow the plaster patch to dry for 24 hours.

  4. Apply a second coat

    Apply a second coat of the plaster compound over the initial coat. Extend the edges 1/2 inch beyond the first coat, smoothing them into the wall. Allow this second coat to dry overnight before sanding and painting the wall.
