Cement Boards

[DIYMARK]

I am tiling a cloakroom and small lobby which have a new screed floor. I want perfection, and there are slight imperfections in the level so is there any problem with laying down aqua board? If so, does it require fixing?

Floating is a bit tricky because we there is a gap all around the floor where we have put wide foam strip for expantion (standing upwards) so the mix could leak away down the sides.

I am also battening out around a Geberit WC frame. Should I batten over the top of the frame or stop with battening level with the top?

I am thinking I will tile the top?

I would'nt be putting aquaboard on a screed floor, could'nt you use a self leveling....

For what reason? Self levelling is tricky because of gap around the screed floor for the self levelling to escape.

If you're worried about levelling compound running away, use draught excluder or silicone to form a barrier, then remove once the leveller has cured.

Is Aquaboard recommended to use for laying tiles in bathrooms on 18mm plywood?

I'd use 6mm hardie glued and screwed but it dos'nt prevent bounce/deflection on the floor...
