Your still looking at a day per millimetre if you want sand and cement screed

If you go for 50 mil pumped concrete it cures in a matter of days

25%  extra though

You can put additives in which greatly speed the drying up. I added some to my sand cement screed and it was ready to tile in  14 days. 

 

It's not so much the drying, it's  the curing with UFH.

 

Cadnans who are doing my UFH next week still advise gradually heating the screed over 28 days before tiling even when using dura matting.

 

Years ago before the advent of flexible adhesives we used to screed in the morning and lay boards and tile in the afternoon. I can't remember any of those lifting.

 

This will be the first time I've had UFH in our home so I'll err on the side of caution.

Mine was a mapie product that was basically a rapid hardener so it cured and dried out fast. I still followed the slight increase in temp each day when I got the plumbing sorted. 

Any reason you are in such a rush to tile??

Avoid liquid screeds if your tiling / bonding the floor covering down. A lot of prep work after its cured. Nowhere near as tolerant as dry S&C screed for laying on 'too soon' too.

I'm with Declan. Why the rush? There are companies who will put a sand and cement screed down and certify to 'dry' in very short timeframes.

 

Ronacrete

 

Flowcrete

 

@tillywiz, have you spoken to either of them ? I'll ring my guy in a bit and see what he has to say.
