DO NOT BUY!!

I bought this for the obvious reasons.. But it left a white film over EVERYTHING. Left it on my dark grout and tiles. I tried cleaning it off with everything I could and nothing gets this stuff off! A waste of money and it will waste your projects!

Grout sealer.

This product MIGHT be ok for grout used with colored ceramic tiles, but DO NOT use on stained glass. It leaves a film on the glass that is almost impossible to get off. Put some on some scrap glass and come back an hour later. You'll need steel wool.

Love this sealer!

Hazy film comes off with polish remover with acetone.

Best I've found for polyblend grout

Yes, this stuff does leave a film on the tiles. It's worth it though, because it seals like nothing else - no grout flaking off and ruining your project. I use a paint brush and apply the sealer only to the grout lines. I scrape off any excess.

Ruined three tabletop mosaic projects

Do not buy. We covered three tabletop glass mosaic projects with this "clear" (per the label) sealer. Applied like white glue; thought it would dry clear overnight. Not the case. Acetone is helping on the glass pieces; dark grout will have to be redone.

Don’t use this!!

The product should specify that it causes a film on stained glass! I am painstakingly cleaning the film off the glass on a large mosaic tabletop (with nail polish remover, thanks to another review) and will never use this product again!!

Ruined my large mosaic window

The bottle says, dries clear, but IT DOES NOT! Fortunately, I read review online that suggested using acetone to remove the cloudy film on my glass. This product also turned my black grout to ugly gray.Thanks to Hobby Lobby for the refund! Take off shelf!
