Like any solid surface, high impact blows can harm granite. Because of its crystalline structure, it can chip if subjected to sharp hard objects. Wear and tear can sometimes cause scratches and chips in the granite. There are a few things you can do to repair the cracks and scratches to look like new.
Apply granite cleaner with a sponge. Wipe it squeaky clean. Dry with a lint free clean towel. Add 1-inch of extra masking tape around the affected area.
Mix Granite Epoxy - wearing protective clothing as instructed on the label. Read the instructions thoroughly and mix the epoxy accordingly. Apply the epoxy to the damaged area with a putty knife.Smooth the epoxy over the damaged area. Wipe away the excess with a razor blade and allow the epoxy to dry completely for the required time. Refer to the instructions that come with the epoxy filler, as some of the materials differ in their drying times.
Seal the affected area when its dried. Refer to the directions on the product to apply it correctly. The sealer should be applied before replace anything on the granite surface. Remove the tape and your fix is complete
