Step by Step Instructions

1 Prepare the surface of the plaster crack
2 Cover the crack with plaster compound
  • Step 1. Prepare the surface of the plaster crack

    Scrape in the crack with your putty knife to open it up a little and give the plaster a bit more surface to stick to. Then sand around the crack to roughen up the paintwork. Now dust the surface down with a rag and cover the crack with a piece of jointing tape.
  • Step 2. Cover the crack with plaster compound

    Scrape the plaster compound into the crack and flatten it on to the wall with your paint scraper. Once the compound is dry, lightly sand it until it is smooth. Dust the wall off and apply a second, slightly wider coat of plaster compound to the wall. Again, let the compound dry, sand it smooth and dust it down. Now the crack is repaired and your wall is ready for painting.
