I regrouted the floor of my shower, and I think there's a problem. The grout
turns gray when wet, then white again when it dries (the old grout on the
walls doesn't change color when wet). I used an unsanded white grout
(Mapei), and sealed it too. Any ideas? Thanks.
Thanks, Al. I did not know that the grout on the shower floor needed to be
the sanded variety. Everything I read always said to use unsanded grout for
the shower. Do you think it is worth the effort to regrout the floor for
