    ive just ripped up the tiles and the subfloor in the bathroom(downstairs).
    like most of the houses around here they originally had pitch pine flooring and now that ive removed all the rotten timber im left with bitumen on top of concrete. i need to bring the level of the floor up and i had planned to use consecutive layers of compound, but is it ok to pour this onto the bitumen. i had originally laid a subfloor of ply then tiled onto it, but a leaking rad and shower door has destroyed the ply and i dont want to go down that road again. i plan to tile directly on top of the leveling compound. thanks in advance.

    How much height do you need to raise?

    I think you'll need to use a primer over the bitumen. From what I can find on the internet, Ardex may have what you need and will be able to advise you.

    You may need to take the bitumen up depending on its hardness. 10-12mm is a lot. You may need to add sand to leveling compound or get one with it added. It should say it on the side of the bag(thats not a smart answer) but if it does not ring the products techanical advice.Dont trust the shop.
