Granite is a popular material for counter tops in the kitchen and bathroom, but the nature of granite is prone to chips. Fortunately, there is a way you can repair small chips at home using some tools found at a hardware store. Chips usually form in granite if something heavy is dropped on it. If the chip is very large, you may have to replace the panel itself, but small chips can usually be covered up so they are barely noticeable.

Wipe the chipped area down with methyl-ethyl-keytone, a solvent that is often sold in paint departments.of hardware stores and home centres, to clean the surface and remove any oils. Dry the area with a blow dryer to get the granite totally dry.
Line masking tape around the chipped area. This "frame" will prevent excess epoxy from making a mess around the area.
Put on latex gloves, open a window to provide some ventilation, and mix together epoxy resin with tinted granite powder. Granite powder can be found through online retailers if you can't find it in stores. It is basically granite rock (in varying colours) that has been crushed to a fine powder. When the tint matches the counter top, add the hardener. Read the manual to find out how much hardener to add, since it varies by brand.
Fill in the chipped granite with the epoxy shortly after adding the hardener. Fill the hole completely and try not to get any on the surrounding area. Smooth off the top of the epoxy so that it is even with the rest of the granite panel.
Take a clean razor blade and gently scrape the surface of the epoxy to make it perfectly smooth while removing any excess.
Wait 24 hours for the repaired chip to dry.
Buff out the area with sandpaper if necessary, using a very fine grit. Be careful not to scratch adjacent surfaces.
Paint sealant on the dry patch with a paint brush. This makes the restored area look shiny like granite.

- Only add a small amount of hardener, or the epoxy will be ruined.
