Screed is laid - laying tiles in HAR due to heat pump?

Hey,

the screed has been in place for 1.5 weeks. Unless anything changes, the heat pump is supposed to come in week 15. Now the area under the heat pump should also be tiled. My construction manager said that with a diffusion-open adhesive, the tiles could be laid there. What do you think?

And if yes, then only in the area of the heat pump or should the HAR and the adjacent storage room be tiled as well?

Thanks!

By the way, what tile sizes do you have in the HAR? Maybe even some pictures?

Take an s2 adhesive, which is basically approved from curing onwards (usually stated from day 3 after screed laying in the datasheet) and apply it only around the absolutely necessary area for now. Is that cement screed?

Wet-in-wet works. And after 1.5 weeks it still counts as wet.

Yes, it is cement screed

how long is that considered wet?

The background is that I would still buy tiles today before the hardware stores close, and the tiler—if he is allowed to continue his work—will tile if he has time...

I'm not a tiler either, but ours said about 2 weeks.
