I've started tiling my bathroom, floorboards are all screwed down and tight, and i have 6mm hardiebacker to lay first.
but there is a dip from the centreline of the room towards one corner of up to 10mm but mostly 4-6mm. on one side.
do i hardiebacker then level up? or level the floor first then hardiebacker?
and will bal rapid flex one be ok to use to level it up? ( i have spare) or do i need SLC?

Yes , Hardibacker, prime and slc. 👍
Thanks, :)
do i need to prime the hardibacker before levelling?
i've got plenty left from priming the walls, but didn't think hardi had to be primed?

It can be primed if dusty or simply wipe over with a damp sponge.

Thanks again :cool:
looks like a trip out to get some leveler then, pity as i have a couple of bags of bal rapid flex left over,
but leveler will be easier to lay...
