How to Fix a Cracked Granite or Corian Countertop

Granite

• 1

  Clean the granite with a sponge soaked with warm water and mild detergent to ensure the crack does not contain any dirt or debris that will interfere with the repair. Dry the stone with a towel.

• 2

  Fill the crack with a granite epoxy repair. Some epoxies are clear and naturally blend in with the surrounding stone; others have colors added so the epoxy matches the granite color as closely as possible. Follow all instructions on the package for best results and remove any excess with a razor before it dries.

• 3

  Sand the repair with a fine sandpaper to even out the repair and make it even with the surrounding granite. Wipe away any loose sand with a rag.

Corian

• 4

  Clean the Corian with an ammonia-based cleaner prior to repairing. DuPont recommends avoiding glass cleaner because it leaves a residue. Rinse the counter once cleaning is complete and dry the surface with a towel.

• 5

  Sand down small cracks with a blue or gray abrasive pad that is included in a Corian repair kit. Sand down the crack if it is shallow to make less visible.

• 6

  Insert an epoxy repair into the Corian crack and wipe away the excess with a razor or rag. Allow the repair to dry.
