Please recommend a sealer for my backsplash/grout
My contractor finished grouting my new backsplash yesterday. The backsplash is a mosaic tile comprised of glass, stone (marble, I think), foil painted tiles, and "deco" tiles. Many of the painted and deco tiles have an uneven/rough surface, so, given that with the stone tiles in the mix, I want to seal the backsplash as well as the grout. (The grout used was Mapei Keracolor U (unsanded).)
I've read good things about Miracle Sealant 511 impregnating sealer, but the specs only mention use on sanded grout. Can it be used on unsanded grout?
Do I need to use 2 different sealers -- one foe the grout, and another for just the tiles? I really hope not, because my tiles are only 1/2" x 1/2.
I'm also unsure how long to wait before I seal. I've read anything from 72 hours to 30 days.
TIA for any suggestions.
