Laying Ceramic Tile over 2X6 T&G Floor

The floor is 2x6 T&G on 4X8 beams, 32in OC, (11.5) ft span.

I am planning mosaic tile on 1/4in Hardibacker. I want a durable, trouble free result, but want to keep the floor thickness as thin as practical. Can I achieve this without another layer between the Hardibacker and the T&G? If thickness were not an issue, I would put down 23/32in Advantech that I have on hand.

Any suggestions?

32 inches on center? Are you sure?

Won't work.

Not wise to put only tilebacker over that type of dimensional lumber. You need the plywood and I would suggest 3/4" ply, then the Hardie. Even then, that type of structure is iffy for tile, especially mosaics.

How about a nice laminate flooring?

1. 32 inches is correct. This is a loft in a log home.

2. Had not considered laminate. I tend to think tile in the bath for water containment. I guess I could stay rustic and keep the T&G as the finish floor like the rest of the loft.
