I made that mistake with our dining room floor!
What I am curious about in respect of removing vinyl tiles prior to
screeding
is how important is it to remove traces of the bitumin-like adhesive from
a
concrete surface. I had the devil of a job with the dining room, making
only a
50/50 job of it with a flamethrower and scraper.


When a job eventually makes you consider setting light to the house because
it'd be easier, it's time to just go for it, in my opinion. Removing floor
tile glue/bitumen is one of those jobs.
Nothing untoward has happened in the 5 years since I put the levelling
compound down and the ceramic tiles we laid over it haven't shown any signs
of movement.
