I have a crack (not all the way through) on my counter top. Can I just wet sand this myself?

    No you need to apply filler. . You'll just scratch it. Go to a marble store to see what color works for you.

    Step 1

    Clean the surface around the crack thoroughly with acetone or a 50-50 mixture of household ammonia and warm water. Dry thoroughly. Don't use a product that will damage the finish on the granite.

    Step 2

    Mix granite epoxy according to the manufacturer's directions. Mix only enough hardener and resin to use in 10 or 15 minutes.

    Step 3

    Use the color pigment kit to add color to the epoxy, again following the manufacturer's instructions.

    Step 4

    Spread epoxy in the crack with a small tool, such as an artist's palette knife or a foam brush. Use a toothpick in very small cracks. Quickly wipe up any messes because once the epoxy hardens it will be very difficult to remove.

    Step 5

    Seal the crack in the granite with granite sealer. Apply the sealer, let it set for 10 to 15 minutes, then apply another coat. Let the crack repair cure for a day.

    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.

    Another cool suggestion, thanks.
