    I am putting tile in my kitchen and have grouted the tile but I find that in some areas the grout continues to crack even after regrouting that area. What am I doing wrong?

    How wide is the space? Are you using sanded or unsanded grout? How thick is the consistency of the grout?

    There's a remodel forum, but:

    1) is your subfloor strong? If not and the tiles move, the grout will crack
    2) how wide are the grout lines? Wider lines need sanded grout.

    Is this on the floor or counter top?

    Cracks mean movement. Could be from numerous sources: subfloor too thin, improper thinset, no decoupling layer (cbu or membrane, or really expensive flexible thinset), joists too springy, you used mastic rather than thinset (bucket pre-mixed verses powder you mixed up), not enough coverage, you walked on the tile too soon after setting, etc.

    A good place for tile info is www.johnbridge.com. They eat, drink, and sleep tile there.

    This should be in the remodel forum not plumbing, but I would guess bad backing, the tile is only as good as what is behind it and the glue you used. Corners will always crack and must be caulked.
