Would 12mm plyboard be right for this?

[DHTiling]

Make sure the floor boards are well fixed ( screwed down)....then ply over with 12mm ply and tile using BAL fastflex and BAL wide joint grout with GT1 admix or similar products........this should give you enough height for the carpet to match the tiles floor in height.........

Backerboards are ideal for bathrooms but if you need the height for the carpet then ply is the way to go...........although backer board does come in 12mm as well.........

Good luck.........

Dave shall i not skreed over the floorboards with anything first and then ply? or have i been misguided here

someone said i need to skreed over with something to make sure the ply sits properly even though the floorboarded floor may seem even

You only really need to level the sub floor if it is undulating or out of "flat". Self Levelling Compound is what is normally used for this. The choice is yours and it depends on how "Flat" you want you sub floor. The flatter the better in my opinion, but if you have not used SLC before, it is by no means straight forward.

Arditex by Ardex is ideal for this though it does stink a bit! it is a 2 part latex based leveling solution. They also do a low odour version but I have never used this.

Lol love the username Grumpy and thanks for the reply.

You see regarding the floor being flat, yes it is flat but because the building is built on a slope it isnt exactly centre level. The other thing is, since the floor boards are in the sections I am a little concerned whether the change between each bit has any effect on the ply i.e. will a little 2 mm kink underneath 12mm ply have any major effect.
