Advice for tiling bathroom floor

[Chrisp69]

Folks I'm after some general advice for tiling a floor... I'm going to be laying 60 x 60 tiles.

So I've replaced all the floor with 22mm T&G P5 and I've going to lay hardibacker over the top. Should I SBR the floor before fitting the hardibacker or just make sure its good and clean?

So once the hardibacker is down, do I need to prime it before tiling over it?

With the size of the tiles, would you say use a 10mm square notched trowel and should I back butter the tiles?

Thanks folks... not as experience as you lot and I just think the more knowledge I have the better 👍🏻.

In my opinion never does any harm to prime. I use a SBR based primer, dilute 1:3. On the floor and then the boards once down (backer boards are pretty porous so will stop them drawing water out of the adhesive and give you more working time). A 10mm trowel would be fine, I use a half round notch but just my own preference. Always good to back butter larger tiles to provide more contact. 👍

Thank you so much for your reply... you've really just confirmed my thinking 👍🏻. Glad to see I'm on the right lines 😀..

Thanks so much...
