I recently had my bathroom redone. I knew nothing about grout or grout lines ect. and I mean nothing........Anyway, the contractor had used unsanded grout (Durabond fortified tile grout) in the tub area with 1/4" (or larger in some areas)gaps. When he grouted he only put a little grout into each gap and then left and came back in a day or two and filled each gap up a little bit more. That process lasted 1 month. He also used two different colors of grout although they do blend. He never caulked the ceiling or the corners so of coarse they cracked but I also have two other cracks that are not in the corners that are aprx. 5" long. My question is --- Is it ok that the grout was layered? and do you think I should just fix the two cracks or have someone regrout since it's in the bathtub area? Thanks for your imput.....................
