Screed floor dust sealant.

My new extension is just about complete, but I understand that I need to leave the 70mm screed to dry out for around 12 weeks before laying an engineered wood floor. We would like to use the room in the interim but the bare screed is very dusty. Is there any way to temporarily cover or seal the surface which would still allow the drying process? Many thanks for any advice.

Cardboard, hardboard, wood fibre underlay (half way to laying the engineered floor!), old carpet, anything that would dry out.. Though I think I'd just have a big dust control mat in the house and teach the kids to wipe their feet before wandering throughout the clean part of he house. I actually have his situation, a liquid screed in the conservatory that I havdnt got around to tiling yet. It was laid nearly 2 years ago and has been trafficked daily. It's no longer a major source of dust. Intense vacuuming routine may be enough, see how you go (though your screed sounds like sand n cement, so may differ)

Did you install underfloor heating? It can be used to force dry the screed
