Before we go ahead and seal our newly tiled bathroom, is it normal for the grout to get a wet look when wet which dries out to the dry color sought after? The grout acts similar to cement/concrete when they get wet.
We have never seen this happen with other tile, and if typical, is there grout that does not act this way?
Will sealing fix this? If not, we want our tiler to fix it before we seal.
