We have a timber frame home. The second floor has 2×6 T&G decking over the 4×8 and 6×8 floor joist on 30 inch centers. We would like to lay tile in the 2nd floor bathroom. I was thinking I should put down a layer of 1/4in Hardie backer and Schluters uncoupling membrane. Tile size would be 12×24. My question, is this a sound, long lasting installation over this type of floor?

Call Schluter tech support but if the span is ok with them they will tell you not to use the Hardiboard. They have very specific rules and Hardi is not included
