Q: In the process of a home remodel, I’ve noticed the grout in my new bathroom varies in color. The tile installer and I agreed on a gray tone, which I see on the floor and maybe a wall or two. But the grout in the shower and other walls is definitely black. Can this be corrected without damaging the porcelain tile?
A: There’s a good chance the grout for your project wasn’t properly mixed. Fortunately, the problem can be fixed with no damage to your tile.
