We recommend sealing marble and granite countertops twice annually. The reality is you can never over-seal your stone. Frequent sealing provides constant protection against most oil-based stains and the same is true for water-based stains such as tea, wine or coffee.
Water should bead on stone surfaces, indicating the protective seal is working. To check your stone, pour water (about 3 inches in diameter) on the surface in several locations and let it sit for 30 minutes. If you see a dark mark or ring, the water is penetrating the stone and it’s time to reseal.
One of the most common products on the market is Granite Gold Sealer®. It contains no harsh chemicals. It is both safe and easy for the average user to apply. It’s literally a spray-and-wipe solution.
In six simple steps, here’s how to seal granite, marble and all other natural stone for about 10 percent of the cost of having a pro come do it for you:
Make sure you thoroughly clean the surface with a safe-on-stonegranite cleaner. Granite Gold makes a cleaner (approx. $6).
Spray Granite Gold Sealer on the surface in a 3-foot section.
Immediately wipe into stone with a lint-free cloth.Do not allow sealer to dry on the surface – it will cause hazing.
Buff dry with a lint-free cloth.
For maximum protection, repeat the process 2-3 times.
Wait 24 hours for sealer to cure before using a granite polish such asGranite Gold Polish®to add shine and luster.
Note: Using Granite Gold products is just a suggestion. There are other products available at most home improvement stores.
