Kitchen floor tiling - Currently laid with Karndean - Tile Advice

[BroughtyTiler]

Hi - I have been asked to tile a kitchen floor which currently has Karndean (Or other such...) type flooring stuck possibly onto a thin board, but it is ultimately all stuck to a concrete/screed subfloor.
I've never been asked to lift this type of flooring before doing the tiling work, so...
Does it leave the whole subfloor sticky?
Can you then tile straight onto that or does the sticky stuff have to be removed/treated?
Any help greatly appreciated.
Cheers

Standard practice prior to tiling is to create a floor that is able to accept tiles.
In this case, rip everything up to expose the bare floor. Assess the floor for movement. Repair and make solid without movement. Overboard with cement board as per instructions. Tile.

Thanks for the reply...
I wouldn't normally overboard a concrete/screed floor with tiling boards as you would normally just tile straight onto that, which is why I was concerned about any adhesive being left on top of it.

No mate, I was talking about a timber floor when I talked about movement and covering with cement board to strengthen any vertical bounce.
As you well know, concrete floors suffer from lateral movement sometimes, and that is where anti-fracture mats and screeds come into play.
