Lay the floor before plastering / Cover properly

Good morning everyone,
first of all, thank you for accepting me and I hope for your constructive support :)
We want to move into a new building soon, which will be handed over in Q2. I have found a comparatively inexpensive plastering company.
Since it is a new housing development, unfortunately 2 others before me have already hired this company. Now the company (one-man operation) needs about 3-4 weeks for ProHaus. This means I would have to wait almost 2 months. That is of course annoying because I can't really do much without finished walls.

Now I am wondering if it might be possible to lay floors already and cover them properly.
The internet suggested, for example, thicker milk carton paper (gray foil). Unfortunately, I find very few experiences on this. Otherwise, I would think of thick fleece or cardboard. My thought process is that the colleague only applies relatively thin layers and there shouldn't really be a huge mess. Unfortunately, searching for an alternative company is rather difficult. All other offers were significantly (at least 50% more) expensive. I would appreciate your experiences.
Best regards S4z4

Is the screed already in [yet]?

Yes, the screed is already in. Except for the walls and floor (laminate), everything is ready. I just don't want to have to wait inactive for 2 months for the plasterer.

I think then it doesn't matter, normally the interior plaster should have been applied before the screed to create a sealing layer. Now it doesn't matter anymore.

mhh okay. The question remains, however, whether it makes sense to lay the floors (laminate and vinyl) now if the plasterer comes afterwards? Of course, this is not optimal, but the question is whether it is possible and what your experiences as experts are.

It basically makes no sense to plan it that way, but it doesn’t hurt now either, as long as you, as written, protect the finished floor well. Of course, it’s possible that the plasterer doesn’t like it. He has to get right to the bottom, I don’t know if it bothers him if there’s 3mm of protective fleece lying there. You should ask him. Or just take another plasterer who is faster. Allegedly, there are reportedly more capacities again now because of the many cancellations. Whether that beats the 8 weeks, I can't tell you.
