    Hi I've tried to find the answer to this everywhere but seem to get conflicting views.

    I have an old concrete subfloor which is a little damp so have covered with wickes liquid dpm which is bitumen-based. But I now need to level this before tiling but don't have much height to play with - 10-12mm.

    Can I prime the bitumen and then pour on a latex slc? Will it stick?

    If not is the another way of levelling on top of the bitumen before tiling with ceramic tiles?

    Thanks for any help.

    I think I've found the answer. Ardex Arditex NA. Does anyone have any experience of using this? Thanks

    Thanks for the recommendation. Just put the NA down, how long should I leave it before putting an f75 dpm on top? The NA it about 8mm at its deepest. Thanks.

    Thanks for that! It just wasn't entirely clear. I'll give them a call.
