You want thin set morter. Not pre mix. It will not dry under the hardi. You can get away with an unmodified under the hardi since it is getting screwed down also. Do not use dry wall screws.
Most pre mix can only go up to 12x12 or 16x16. Si ce the boards are 36x60 they dont get enough air to dry.
Your subfloor should be 3/4 min before hardi.
Pm for any other questions.
