Screeded floors - OK to use the rooms after it's set?

[dogfonos]

Would be grateful for your views on using rooms that have recently been screeded (to 100mm depth laid on 100mm insulation with damp proof course beneath).

I know that the screed should not be walked on for the first few days and that's not a problem. I also understand the need to wait several weeks to allow moisture to evaporate before applying the final floor finish, sheet vinyl.

My question is: after the first few days, can the rooms be used or will that cause problems of some sort? For instance, should something (breathable?) be laid over the screeded floors to prevent dust being kicked up? Or will dust not be an issue?

Thanks for your consideration.

I'd let the screed dry for a week or two. TBH the biggest issue is dust - cement screeds generate a lot of very fine dust if you walk over them (a nuisance, but little more) and you shouldn't cover them at all because that slows down the rate of curing (and evaporation)

A week or two? A lot longer then that. Drying time will be 100- 150 days for 100mm depending on drying conditions.
You need to do a moisture test after 6 weeks and see how it's drying.
