6 easy steps of fixing a crack granite sink Now take a step-by-step process of how to fix a cracked granite sink.

Step 1: Cleaning The Sink

The first thing you need to do is the cleaning process. Before you start the process of fixing your cracked granite sink, you have to clean the sink thoroughly.

If you do not clean the sink properly before starting the job, likely, the epoxy may not set properly.

If you clean the sink surface, you will also ensure any surface scratches that may have formed would be removed. Now take a look at how to clean the sink surface.

  • Run hot water around the sink
  • Take scouring powder and pour them into the sink 
  • Let them sit for about a minute
  • Dampen a towel with warm water and wipe the surface of the sink using the damp cloth
  • If you see any hard spots on the sink surface, then use a soft scrubbing brush to scrub the spots area. Press firmly on the spots while brushing and then rinse out the sink
  • Wipe the sink with a clean dry cloth

Step 2: Preparing The Sink

After completing the cleaning and drying task, inspect the crack in the sink. A large crack is easier to fix than a small crack.

The preparation starts when you apply the epoxy. You do not get any on the rest of the sink.

  • Use painter’s tape around the edges of the crack
  • Cover the entire kitchen sink area without covering any of the crack itself
  • The idea is to get as little of the epoxy on the rest of the sink as possible

If you do not have painter’s tape, you can use a newspaper or something similar. Once you are done with this job, you can now proceed to mix up the epoxy filler.

Step 3: Applying Epoxy

Pick an epoxy that states on its packaging. You can get the epoxy from any store near your home. It can be used for granite or stone repair. Epoxy is the most effective ingredient to fix any crack in the granite sink.

Applying epoxy can be a time-consuming process, but once you have done it right it should not take more than a couple of minutes.

For Larger Cracks

  • Smear the epoxy in the crack until it is filled
  • Use a plastic spatula or the tool you used in mixing the epoxy
  • Use the spatula to press the epoxy firmly into the crack
  • Add more epoxy if needed
  • Smooth it out as best as possible
  • Any bump around the surface area would need to be sandpapered later

For Smaller Cracks

Filling small cracks is the same process that you have done to fill the larger cracks. But you need to be careful when you apply the epoxy.

Instead of smearing the epoxy over the crack, you would want to take it more slowly to avoid having too much extra epoxy.

Step 4: Allowing The Epoxy To Dry

After applying the epoxy, allow the epoxy to dry. Usually, the drying time is approximately 24 hours. But depending on the brand you have used in your sink.

Follow the drying time on the package that is allocated by the manufacturer.

Step 5: Smoothen The Sink Surface

After the epoxy dry, check the sink surface for how smooth it is. It can be uneven once you apply the epoxy to the sink area. Use sandpaper to smoothen out the surface.

Step 6: Cleaning And Buffing The Area

Once you smoothen the area and you are happy with the smoothness, wash the sink more time before you buff it up and make sure it shines. Use a wet buffing pad, then gently move through, and scrub the surface of the sink.
