Hi all,
I've researched and researched on the best thing to do when tiling my bathroom floor. The floor is T&G chipboard, the green stuff (property about 18yr old), and is pretty sound in my opinion.
I was going to ditra matt over it but some tilers i've had over some said thats fine, some said to put down 12mm ply, another 6mm ply, another tile straight on.
I've decided to put down 6mm hardie backer, and then ditra matting. My question is why do i have to put adhesive on the underside of the boards and then screw down, instead of just screwing them down? I thought the whole point of overboarding like this was so that no wet addy would touch the chipboard, if i'm going to put adhesive on the chipboard why would i not just put the membrane straight on top?
Thanks in advance!
