How to Repair a Silgranit Sink

Silgranit sinks, made by Blanco, are a line of manufactured sink products. They are made of a molded material that consists of 80 percent granite. Silgranit sinks are designed to be chip resistant and impermeable to scratching. However, accidents can happen, and even a Silgranit sink can be in need of repairs. You can patch up a Silgranit sink using epoxy, which will fill the scratch or chip and blend it into the rest of the sink. If the sink is structurally unsound, you'll need to replace it.

Instructions

- 1
  Wash the chipped area with granite cleaner and hot water. Scrub with a nylon scrub brush. Rinse well and dry thoroughly. Do no proceed until the area is completely dry.
- 2
  Mix the epoxy with the epoxy color on a piece of cardboard until it matches your sink's color. Follow the manufacturer's instructions for mixing, since different brands of color and epoxy vary in how they are mixed.
- 3
  Scoop some of the mixed epoxy onto a razor blade and work it into the flaw. Hold the razor blade at a 45 degree angle from the sink. When the chip is full, scrape a clean razor blade gently over the chip to remove any excess epoxy.

  Allow the epoxy to cure according to the manufacturer's instructions. This varies from one to 36 hours. Do not use the sink before the epoxy cures.
