Heidi196512 Dec 2020 22:29Next week, the screed will be installed in the new build. Until now, I thought it needed to dry for at least 6 weeks before the tiler could start. Now the contractor says it can be done as soon as the floor is walkable, and besides, the tiler is available immediately, so we should arrange to get the tiles as soon as possible.
So it’s either immediately or after 6 weeks. Where is the logic in that, and how can the screed properly dry with large tiles (60 x 60 cm / 24 x 24 inches) on top?

It should not dry for 6 weeks; it should dry for x weeks, and then the residual moisture is measured. Each room should have a small hole in the center with a plastic rod inserted for the measurement.
There are additives that allow the screed to dry faster (very quickly). This is expensive and is listed as an item either in the scope of work description or in the construction contract.
However, the client is often told something different to keep the construction moving forward.

The screed should not lose moisture too quickly, for example on the surface, to prevent it from becoming crumbly (this is my layman’s understanding). If the tiler is reluctant to work in the "haze" and opens all the windows wide, the screed could cure unevenly and unfavorably. However, @KlaRa can surely advise on what is “best” for the screed.
If necessary, agree with the tiler that only the windows in the specific room are opened, but avoid opening windows opposite each other to prevent cross-ventilation.

by the way: what is the rod for? Here, it was triangular blue foam. Placeholder for the measuring device?!
