Sealing screed surface before dry?
Discussion
Hey OP, not a thread hijack, but literally just finished the membrane and UFH piping for the poured screed coming tomorrow. Nominal thickness about 55mm. Not anticipating being in before Christmas. UFH to be pressurised for the pour. I was told 2mm dry per day, so 5-6 weeks before flooring. Floor covering to be a mix of of engineered wood, carpet and tile in different rooms. Wet room bit shuttered off to be finished by hand next week ! Was told to keep windows open to allow air flow to maintain drying (and get burgled) . Repeated by screeder and engineered wood company that it cannot be rushed... don't even think about putting on UFH, tiling etc this side of 2018.

OP, I’m no expert but be careful force drying with a dehumidifier like that.
Any screed I’ve ever seen the longer to dry the better - even to the extent of actually damping it down with a fine hose spray and covering with plastic to keep it damp for longer!
I’d have thought the better way would be to use products designed to decrease drying time rather than force drying?
But as I’ve said, I’m really only guessing.
Good guess. As above, what you've said will achieve maximum strength. If you only ahieve half strength then that's OK in the majority of cases. If you force dry it and only ahieve one third strength it may be OK, dpends on the mix and end use.Any screed I’ve ever seen the longer to dry the better - even to the extent of actually damping it down with a fine hose spray and covering with plastic to keep it damp for longer!

Ps. I’ve had too many Strongbows to explain proper
