Stone Pro Quartz NanoGuard Countertop Protector (Quarts/ 32 oz.)

Very good

This stuff is amazing! We plan to use it annually to keep our white countertops in good shape.

Great shine, protects well Easy to apply

I applied this to all of the quartz countertops our new house as soon as I got the keys. It’s been two months and so far it seems to have created a barrier that even spills and messes left by my kids haven’t penetrated. I was worried being a first time quartz owner but water beads up on the surface, and even greasy spills/fingerprints have not soaked in. I definitely recommend if you are a human living with other humans who make messes.

It helped a lot with cleaning and in fact there is way less stain on the countertop that we need to deal with

liked that it works!

I applied three coats of this exactly as directed and my quartz countertops seem to still scratch easily. I was really hoping for more, but this seems like it was just a waste of money.

We recently completed a remodel of our master bath with white quartz vanity tops. After being cautioned by our contractor about the potential for staining I selected this sealant as a level or protection. Per the bottle instructions, I applied with a microfiber cloth and allowed the five minutes to set before wiping. The product was easy to apply and clean, I had no issues with impacts to the quartz finish or negative interaction with neighboring materials (walls, cabinets, faucets, etc. I don't have any interesting in testing the stain resistance but at the very least it provides a level of comfort in that I tried something to be preventative of an expensive project. The bottle is big enough I have plenty of product remaining to reapply in the future.
