Instructions for How to perform a Granite Repair
Caution: These Granite repairs can be difficult and are often best performed by a professional. If you are a do-it-yourself type of person, you can perform these repairs using quality products, the correct tools, and a good amount of patience. These represent the some of the most common types of granite problems a homeowner may face.
Granite Repair: Removing and Replacing Sink Silicone
To perform this repair, you will need the following supplies:
1) A 2 1/2 Inch 5 in 1 painter tool, putty knife or razor blades (Be careful!) to remove old silicone.
2) 1 tube of Kitchen/bath silicone. I suggest using a color that matches the color of the sink.
3) Mineral Spirits or Water for post-installation cleanup. Check the label on the Kitchen/bath silicone to determine which in needed for cleanup
4) Caulking Tool. A caulking tool is used to smooth caulking after it is injected into the seam. Caulking tools work much better than your finger!
5) Caulk Gun
6) Rags and/or paper towels
7) Time. This type of repair will take 45 minutes to 2 hours for the repair, depending on such factors as: sink size, sink shape and condition of old caulk. In addition, you will not be able to use the sink for several hours. Check the label of the silicone for specific drying/curing times.
Begin this granite repair by carefully removing the old caulk/silicone using your painters tool, putty knife or razor blades. Use caution to avoid scratching the sink or granite. I have found that using a razor to cut the top edge of the caulk/silicone (by the granite) and the bottom edge of the caulk/silicone. Use your painters tool or putty knife to pierce the caulk/silicone and pull out a small amount. Once you get it started, most of the silicone should come out like a string (unless it is really rotten and hard). Use a razor blade to carefully remove all remaining caulk/silicone.
Once you have removed all of the old caulk/silicone, you may begin installing the new silicone. Use the caulking gun to inject the silicone into the gap until the gap is completely filled and slightly overflowing. Use a caulk tool to smooth the surface of the caulk and remove any excess. As you tool the silicone the caulk tool will become loaded with the excess silicone. At regular intervals, you will need to use a rag or paper towel to remove the excess silicone from the caulk tool.
Once the new silicone is smoothed and the excess has been removed, you are ready for the clean up. Check the label of the silicone to determine the best clean up method (water or mineral spirits). That it! You have just completed your sink repair.

Granite Repair: Cracks & Seams
To perform this Repair, you will need the following supplies:
1) Nylon Scrub brush. Used to clean the crack prior to installation of epoxy.
2) Knife-grade 2 part epoxy(must be purchased from a natural stone tool/product specialty store). While expensive, I have found that epoxy is the best for use in areas that will come into contact with water. Many stone professionals refer to polyester resin and acrylics as "epoxies". When purchasing check to be certain that the product is a true epoxy.
3) Epoxy color kit(must be purchased from a natural stone tool/product specialty store).
3) Razor blades. Razor blades work well to smear the epoxy into/over cracks and to remove excess epoxy.
4) Acetone. Acetone is a solvent used for cleanup of tools.
5) Putty knife. The putty knife will be used to mix the color(s) into the epoxy and to mix the two part epoxy prior to installation.
6) A small piece of cardboard. The cardboard will be used to mix the epoxy.
7) Rags or paper towel. To clean up tools after installation.
8) Granite Cleaner (NOTE: Always test your granite cleaner in a small inconspicuous area prior to use on the surface to determine if the product is suitable).
For this repair, it is important to understand that there are actually 2 different ways to fill cracks and seams. One method involves filling, then sanding the crack or seam to create a smooth appearance. The other method, as described here, involves filling the crack without sanding. The result will be a filled crack or seam that is not perfectly flush with the surface of the granite.
Begin this repair, by carefully removing all debris and/or old epoxy from the crack or seam using a razor blade and the scrub brush.
Next clean the crack or seam using the granite cleaner and the scrub brush.
After the crack or seam is completely dry, you may install the epoxy. Begin by reading the directions on the epoxy. Color one of the parts of the epoxy to match the granite, mixing using the putty knife. Then, after you are satisfied with the color, mix the two parts of the epoxy (part A and part B) according to the directions on the epoxy can using the putty knife.
To install the mixed and colored epoxy, use a razor blade. Take a small amount of the mix on the blade and use the blade to smear the epoxy mix across the seam or crack at a 45 degree angle. Take care to not leave much excess epoxy mix on the granite surface. Repeat until the entire crack or seam is full. Be sure to work quickly as the epoxy will begin to harden in just a few minutes.
After the filling is complete, use new razor blades to remove any excess epoxy mix from the surface of the granite.
Clean up tools using Acetone and the rags or paper towels. Thats it! This granite repair is now complete.
