bright white grout - epoxy?
I was considering using grout from Custom (Fusion Pro) for a shower with subway tile and another shower with Porcelanosa Madison Nacar tile but I'm concerned about the fact that it says not to use it when temps are above 90 degrees. We're in SC so it's hot! Is this true of other grouts? Also, no one locally carries it and the tile guy is setting tile now so I was hoping not to have to order the grout and delay the process. I would like to use the best product for ease of cleaning considering it's white grout and the porcelanosa was pretty expensive. Is epoxy grout the solution? Does it turn yellow? The grout joint on both showers will be 1/16".
