I have a valley in the cement and am not willing to use self-levelling. Only maybe around 1/4" off and it's really only one strip of the floor. Seems like using a 1/4 X 3/8 for everywhere but a 1/2 X 1/2 for that line of tiles wouldn't be a bad idea to even things out. Is that a typical practice or do tilers just build up with extra back buttering?
Thanks!
Thanks!
