Tiling Onto Uneven Concrete/bitumen Floor

[Qwerty]

Best removing as much as possible as already advised, then the SBR slurry, followed by a SLC over this.

Alright. Thank you for your advice. I'll talk it through with the other half . Her folks are insistent on the chipboard sub-floor.

Do not turn a concrete substrate into a wooden one, that is not a good piece of advice. Clean the bitumen up and level the floor. Even if you were to put chipboard down (which you shouldn't even consider), you'd still need to put a backer board over it to make it tileable, all those layers would leave you with a 40mm step into the room.

Also, don't forget a expansion strip between different areas.

Okay. Not too sure where that goes but I'll work it out. Thank you all.
