FAQs
Next to diamond, sapphire, and ruby, granite is the hardest natural product on earth. Once polished, natural granite will maintain its high gloss for as long as the owner cares for it. Normal use of kitchen knives, cutlery, and cookware leaves no scratches. Heat has almost no effect on natural granite, making it much safer than synthetic surfaces with polyesters and resins. Pots and pans heated to 900 degrees Fahrenheit will not dull natural granite’s lustrous finish, but the use of trivets is recommended to keep your granite counter clean.
Knives cannot scratch true granite. The only thing harder than granite is diamond. For example, diamond is scored 10 on the MOH’s hardness scale and granite is scored 7. Diamond blades are the only thing that can cleanly cut through granite. Other natural stones like Gneiss and Schist are commonly called granite, but they do not have a MOH score of 7, and they can be probably scratched by knives.
If you use high quality impregnating sealers like DuPont Bulletproof sealer, you should have to reseal your granite every three years. If you use a cleaning liquid called Revitalizer also made by DuPont, you will not have to reseal your countertops ever. A gallon container of Revitalizer usually costs $39, which will lasts 2 to 3 years depending on the size of your countertops.
No. If you use 3cm (1 ¼”) thick granite which is normal, you do not need any special reinforcement. You may need some additional support in the corners of walls that our team can work directly with you on.
