Granite Sink Repair
- 1). Scrub the chipped or cracked area of the granite sink thoroughly with a nylon scrub brush and granite cleaner to remove all traces of dirt, algae and other debris. If the damaged area is near the edge of the sink, scrape any existing epoxy away from the seam with a razor knife. Allow the sink to dry completely before continuing.
- 2). Add epoxy resin color, which is available from home supply stores, to part of your epoxy resin, stirring it thoroughly with a putty knife to distribute the colors. Try to make the color of the epoxy match the color of your sink as closely as possible. Add the rest of the epoxy to the colored portion and mix it with the putty knife.
- 3). Scrape a small amount of colored epoxy up with a razor blade and smear it across the crack or chip, holding the razor at a 45 degree angle. Avoid leaving excess epoxy on the surface of the sink. Working quickly, smear more epoxy across the damaged area until it is filled and level with the surrounding surface of the sink. You have only a few minutes before the epoxy begins to harden.
- 4). Remove any excess epoxy from the surface of the granite sink with a new razor blade. Gently sand over the damaged area of the sink with fine grit sandpaper to smooth the surface of the epoxy. Allow the sink to remain undisturbed for four to six hours until the epoxy cures completely.
