I know this subject has come up from time to time but it seems there are split opinions - is tile backerboard an adequate alternative to ply?
I'd like to get the hallway tiled which currently is floorboarded. The rooms off it are sanded floorboards, so to add at least 12mm ply on top will create a height issue Because of its shape it would be quite a big job to replace the floorboards altogether with 25mm ply so I would like to avoid that.
I've read up and seen the Hardie backerboard video which recommends 6mm thickness and it all looks very straightforward - too straightforward in fact. Would 6mm really provide an adequate non-flexing base even if every board was solid as could be and the instructions were followed to a t? Thanks
