Nano-Technology Granite Sealer, Cleaner & Polish - Great Solution!
My granite countertops in house I just bought were a bit neglected so I thought I would give this a shot. This product came with complete instructions, was super-easy to apply, and appears to have done the job (water is now beading on granite surface and not soaking in after 10 mins of observation). All in all, this is exactly what I needed to seal my granite countertops.

Not a replacement for Liquid Quartz
I saw this mentioned on a discussion board as a replacement for Liquid Quartz for ceramics. It is definitely water repellent, but also definitely not a sealant for ceramics. I got condensation within an hour.

Works well!
I thought it worked well to seal the granite I was using it on. Make sure you wear gloves to avoid getting it on your skin.

O yeah!!!!
Easy to use. NO harsh or flowery smell. Will purchase again. Did exactly what is expected. Can be used again & again to keep counters protected without high gloss shine. Nice buffed finish.

doesn't work
The product didn't work on counters, and the spray top was broken. I ordered a replacement and that was also broken. I returned both

Unfortunately didn’t work for us !
Nozzle broken, doesn’t spray right and after a properly sealed table stain from a juice came right in to a countertop and left stain . Wish i could love it but no. Don’t worry for us . ( photo is after a cleaning with all other products quickly to get if a red juice color )

Excellent protection for stone. Gave my slate fountain a new life.
This stuff is great. After applying once, after 24 hours I thought perhaps I should apply a second coat - but didn’t need it. The product had saturated well enough the first time and one second spray immediately beaded up. It has no odor or ‘out gassing’ and is easy to use.
