OpenSky said:I talked to Bob at Groutzilla today.
in short, he doesn't think it necessary to seal our grout.
Reasons:
1. Non sanded grout can only accept clear sealer, which doesn't last long.
2. Our grout color is already dark, so as it discolors, we won't notice it.
Bob says sanded grout is the way to go, but it requires a minimum of 1/8" grout line, which is in conflict with wood look. He said it's a common mistake to do tight grout lines with light colored non-sanded grout.
we just got lucky that we aren't in that camp.
btw, nice guy, very helpful, talked himself out of $1300 worth of work (1300 sq feet plus backsplash).
Good call on your gout color.
