Stone Pro Quartz Nano Guard, Countertop Sealer for Granite, Quartz & Quartzite, Protector Against Oil and Water Borne Stains(1 Quart / 32 oz.) (Quart Bundle)

My contractor used this product to seal our quartz countertop. So far, it had held up well. Surface is smooth, and much easier to clean than before we sealed it.

I was concerned about doing this process. It was so easy I regret waiting to do it! I have the preferred maintenance spray for it. (Brown label) I can’t attest to durability yet. -Oh the smell really isn’t too bad. I’m scent sensitive and it was ok. No headache or other distress. - The material is like skim milk in color. Very fluid. - Water resistance-I still see water marks near faucet bases. I’m a worry wart so it’ll be reapplied sooner than later. - For kitchen activity fluids I’m quick to wipe things off. (Blood, kool-aid, the oils from canned foods) I don’t even want to test it. Clean as you go it shouldn’t be an issue.
