calling tile and grout experts
Two questions for the tile experts or others out there!
1--Has anyone had experience, good or bad, with "Grout Once"? It's a liquid sealer that you apparently mix in WITH the grout so you don't ever have to seal the grout after installing the tile. Tile store said it's fairly new and everyone's using it. I don't want to be a guinea pig for new tile technology but I'm happy to if this is pretty proven already.
2--Second question: my backsplash tile is a glass and marble mosaic. The grout lines are a bit over 1/16th inch. The tile store is telling me I need to use sanded grout on any tile with grout lines over 1/16 or the individual tiles will eventually pop out. Our tile guy (who has done great work for us before) says unsanded or the marble and glass will scratch. I'm flummoxed on this one.
This is a sample of the BS tile:
Thanks for any input!
