Fast drying screeds .? - Tile Advice

[Dumbo]

Has anybody come across retanol xtreme .
Went to have a look at a job last week .
Capable of tiling after 4 days .
My worry although maybe hard enough I would of thought their is still a lot of moisture .

Andy @Localtiler has just laid to a similar screed, same sort of curing times. Think he was advised to wait a week.
Becoming more and more popular it seems, although not that new to the industry.

I tile on Mapei Topcem screeds after 24hrs on a regular basis. 48hrs for stone.

Is there any underfloor heating in there ? Personally I wouldn’t tile on one so quick without dural or ditra.
