Unless you know where every cable or pipe is under the floor, never use longer screws than the combined thickness of the cement board plus the subfloor.
Here in the US we have Durock cement board and it’s not waterproof. It will absorb water but it won’t crumble like plasterboard. After we install it we come back over and roll on 2 coats of liquid waterproofing that dries to form the skin. Nowadays it’s all getting replaced by foam systems like Kerdi and Wedi. Much nicer to work with but eye-wateringly expensive compared to cement board
I'm just about to do this very thing to a timber first floor bathroom...then this vid pops up as I'm scrolling TH-cam...hooooo...they watching me...I found it very informative and helpful...Will have to find South African alternative products tho...the names don't sound familiar....could be wrong
Congratulations next time round when you want to change the tiles or have a new bathroom you will find you have ruined the original floor. Always better to fit a substrate like ply which can be removed and leave the original floor with minimal damage

Can I install two layers 1/4” hardie backer boards one over another with use of mortar between? It’s to get my proper measurements.
Great video. How would I screws these down into concrete floor?
I assume the adhesive alone would be enough.
Awesome!!!
When I start needing to rip this stuff up that's me finished. Good chance that chipboard floor will need replaced when the cement boards come up.
❤❤ thanks you
did not think the tile adesvied would stick to the wood
Of course it doesn't, you should use polyurethane sika and or screws.

I see what you are saying, but ply isn’t waterproof ?
@Michael thank you for the reply
But he IS installing over a ply subfloor…
If people in the States will be watching tis video talk in inches also please......
White plasterboard in a wet area 😂😂
He did eventually changed it to hardie board within the shower area.
Not porous my ass! Hardibacker will wick water up the wall! And never use this crap for floors either!
