So I have bought my hardiebacker board. I'm going to put it up on Thursday. Quick question, am I right in thinking I just need to stick the 6mm stuff to the ply wood floor with tile adhesive, no screws?

And do you think using hardiebacker 12mm on these stud walls is a good idea? I was going to sceew them to the stud timber with "gold" branded screws.

Just hope the boards don't warp being stood up like this before I get around to doing it on thursday

Just sticking my oar in one one point. In my humble opinion ALWAYS underboard EVERY floor FORMER. Even when the manufacturers say that their product doesn't need it. It does! Think about it. Even with flexible adhesive and grout, tiles and grout do not like ANY movement. Even the slightest movement could result in a hairline crack in the grout (and in some cases the tiles). This will result in water ingress under the tiles. Not a problem as far as leaks are concerned if you have tanked properly. But you will still have water under the tiles and an unhappy client. Like all building work. Get the foundations correct and you are half way there.
