How to Seal Granite and Other Natural Stone
A damaged protective seal leaves granite and other natural stone surfaces susceptible to costly repair and replacement. Frequently sealing granite countertops and any other natural stone surface is among Three, Essential Steps to care for your natural stone, whether it’s a countertop, floor, shower wall or vanity. Sealing frequently will maintain maximum surface protection for resistance against staining, etching and soil build-up. We’re often asked how often natural stone should be sealed. Some in the industry will say once a year; others maybe twice annually. The reality is you can never over-seal your stone. Frequent sealing provides constant protection against oil-based stains such as salad dressing, cooking oil or vegetable oil. When they come into contact with unsealed natural stone, the oils can penetrate the pores and leave unsightly reminders. The same is true for water-based stains such as tea, wine or coffee.
- 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.
- Make sure you thoroughly clean the surface with a safe-on-stone granite cleaner. We, of course, recommend Granite Gold Daily Cleaner®.
- 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 as Granite Gold Polish® to add shine and luster
