  • Call a local stone contractor, this is not a typical homeowner DIY project.

    Try to fix what caused the crack, first.

    If the heights are different between the cracks, can you ship it back up?

    If not, it can be polished flat, after sealing, but not by most DIY people.


    You’ll need an epoxy with a needle sized applicator or a super thin epoxy to work in by hand.

    I would make sure the epoxy is rated for food-Service use, and that the VOCs are low.

    You will need nail polish remover to clean the granite surface, straight razor blades, thick super glue (gel), and if you have a darker Granite Countertop you might want to have dark Sharpie marker. Start cleaning your chipped area with nail polish remover. Let the Granite air dry. Tape off the area surrounding the chip and apply just enough glue to fill the chip and rise just slightly above the surface of the stone. Filling the glue up to within flush of the surface of the tape should be sufficient. Once the super glue has completely dried and the tape removed, use a straight razor blade to remove the excess Super glue by “fanning” the excess material away. Wait and allow the glue to cure before cutting with the razor. The time it takes for the glue to cure depends on how deep the chip was, the humidity in the home, etc.(This next step only applies if you have darker Granite) Once desired results are achieved, you may wish to use a colored permanent marker such as a black Sharpie to color the super glue. A Sharpie is permanent and dries quickly. For lighter colored stones, this may not be necessary.
