    Just got 75mm liquid concrete screed with fibres poured downstairs. Guy said to cover it with polythene for the first couple fo weeks. Does it not seem a bit overkill in winter?

    What's the reason for covering?

    House is insulated and airtight. I think he might have been concerned about it drying too quickly? Although I have no heat in it yet.

    What is the best way to dry out a floor - let it dry naturally or apply a gentle heat?

    Let it dry naturally, the concrete produces its own heat which leads to high humidity in airtight houses...keep doors and windows open as long as possible.

    It can get sauna like inside first 24hours...

    I'm assuming this is not an annhydrite screed over underfloor heating.
    A "liquid concrete screed" suggests a pourable, or pumped screed. If that is the case, then "curing" with polythene is a good idea. It will make the drying process and strength development much more efficient.

    +1 on this. On big pours we'd always cover them. As said it makes the process more efficient and it will out more evenly.
