    What's the minimum for 12" tile? Can the notch be smaller if you back butter the tile, or should you always back butter the tile?
    Customer has a rental where the guy use a 1/8" trowel and the tile popped off. I think the grout was the only thing holding the tile in place. :D
    Anyway, the owner want's me to install the new tile. There's a 5x5 bathroom, a 3 1/2 foot square entry with an angle cut and an 8 or 9 foot by 13 foot kitchen.
    The original backer board is down and she told me they cleaned/smother it out and it's ready to go.
    It's Hardi, probably 1/2 inch

    If they are porclean tile back butter them. Trowel notch is 3/8v notch if I remember right. I think you also need to dampen the Hardi or it sucks the moisture out of the adhesive.

    More important to butter porcelain than regular tile?
    How about regular or modified thinset?
