How to fix a chip in a granite countertop

Granite is one of the most durable and sterile surfaces for countertops. It is still possible, however, to chip the countertop, should a heavy object strike it. You may want to call in a professional to repair a significant chip. The contractor or store where you purchased the granite may offer to repair minor chips for little or no charge, but you can make the repair on your own with the right materials. You can find the repair products online or at some speciality hardware stores.

  1. 1

    Clean the area of the chip with a sponge and warm soapy water. Ensure that the surface is clear of grease and debris. Dry the area completely with a clean towel.

  2. 2

    Place masking tape closely around the chip.

  3. 3

    Put on the latex gloves and mix the epoxy resin with the tinted granite powder, using the tongue depressor. After the pigment is added, mix in the hardener. Read the manufacturer's instructions for the ratio of hardener to epoxy, which varies by brand. In most cases, you will use a very small amount of hardener.

  4. 4

    Apply the epoxy mixture to the area being repaired, filling the hole so that the mixture becomes flush with the countertop. Use the razor blade to scrape off the excess mixture.

  5. 5

    Allow the patch to fully cure. After 24 hours you can add sealant to the area with a paint brush. The sealant will offer further protection and shine to the surface.

Tips and warnings

  • More than one tinted powder can be used to recreate colour clusters on a marbled or speckled granite countertop. Leave a thin layer at the top of the main patch when you fill the chip. Let it cure before adding a separate mixture for each additional colour. You can place the colours side-by-side, filling the final layer until it is flush with the countertop. The colours will come together naturally when they harden.
  • Add the tinted powder sparingly until you get the right colour. A small amount goes a long way.
  • Do not add more than the recommended amount of hardener, which can become lumpy or set too quickly.
