One of the worst things that can happen to your granite work table is for a crack to develop in the surface. A crack in the surface of your work table will be unsightly and frustrating at best and render the table virtually unusable at worst. Fortunately, with a little patience and attention to detail, you will be able to repair cracks in your granite work table effectively and return your table to its former glory.

Step 1 - Clean Area

Clean the granite around the area of the crack thoroughly. To do this, you can either use acetate or a mixture of 50% diluted household ammonia. Just make sure that you clean the area completely and wipe it dry before continuing on to the next step. Be careful about using any other cleaning solutions for this step, as some cleaning products have the potential to damage the finish of the granite.

Step 2 - Mix Granite Epoxy

Mix your granite epoxy. This product can be purchased at any local hardware store. Once purchased, mix the epoxy according to the manufacturer's instructions. Do not mix all of the epoxy at once, however. Only mix as much epoxy as you anticipate using in 10-15 minute intervals.

Step 3 - Color Granite Epoxy

Next, you will use the granite epoxy color pigmentation kit that you have purchased to add color to the epoxy. Add color so that the epoxy matches the color of your granite work tabletop as closely as possible. Again, mix and apply this pigmentation according to the manufacturer's specifications.

Step 4 - Apply Epoxy

Using small tools such as a foam brush or palette knife, begin to apply the epoxy inside the crack in your tabletop. When working in and around small cracks, a toothpick might be your best tool to use, as it can fit into tiny spaces that you could not otherwise access. Be aware that once the epoxy is applied and allowed to set, it will harden very quickly, so you will need to work quickly and efficiently to ensure that you get through your entire project before your epoxy hardens.

Step 5 - Repeat Steps

Once you have used the above steps to fill in portions of the crack in question, repeat the steps as many times as necessary to ensure that the entire crack is filled in. If you apply too much epoxy to an area, wipe the excess epoxy away before it has time to set, as it will be very difficult to remove at a later point.

Step 6 - Seal the Crack

Once you have applied the granite epoxy to your satisfaction, apply a layer of granite sealer to the top of the surface and allow it to set for 15-20 minutes. Once this first layer has dried, apply a second layer on top of it. Allow the tabletop to dry for at least 24 hours before using it again.
