Can grout be used when working with Aspect tiles?
A sand-less grout can be used. A grout containing sand is not recommended as the grout may scratch the surface of the tile in the cleanup process. If you want a grout-line look, colored or white silicone caulking will have the same effect and is easier to apply and at the same time providing a water-tight seal. Be sure to remove excess caulk or grout before it dries.
