Granite countertops are a wise investment for the kitchen because of their durability. However, don't assume that just because granite countertops can fend off more damage than other types of countertops, that they cannot be damaged. All it takes is one careless action for the edge of your granite countertop to get chipped. To help keep your granite countertop looking its best, take the time to maintain it properly.
Seal your granite countertops before they are used. Granite often has small cracks in it that cannot be seen by the human eye. Liquid can get into these cracks and slowly damage your countertop. Apply granite sealer yourself, or ask the company that is installing the countertops to seal them for you.
Avoid sitting or standing on your granite countertop, or leaning against it. Granite may be harder than other types of countertops, but it's also less flexible.
Keep dirty dishes in the sink or in the dishwasher. Stacking them on the granite countertop will not damage it, but a stack of dishes falling could cause a chip in the granite. Be especially careful with heavy pots, pans and mugs.
Don't let children play with toys on your granite countertop. A child banging their toy on the edge of the countertop may very well put a chip in it.
Use a cutting board at all times, even if you only need to cut one thing. While you're not likely to chip the edge of the countertop while cutting through an onion, it will put more wear and tear on the countertop, and make it more susceptible to chipping in the future.
Fix any small chip (no bigger than one inch) immediately. A small chip can be repaired easily, but a small chip can quickly turn into a big chip if ignored--and cost more money to repair. Use granite dust and an epoxy mixture to fill in the chip. In the case of big chips, first try reattaching the lost piece to the countertop instead of just filling it in.
Clean your granite countertops with a soft rag or sponge. Too many rough cleanings will damage your countertop in the long run. Have your granite countertop tested every few years to make sure it does not need to be resealed.
