ᐅ Laying the floor before plastering / Properly covering surfaces

Good morning everyone,
First of all, thank you for welcoming me, and I hope to receive your constructive support 🙂
We are about to move into a newly built house, which will be handed over in Q2. I have found a relatively affordable plastering company.
Since it is a new housing development, unfortunately two others before me have already hired this company. Now, the company (a one-person operation) needs about 3-4 weeks for the job. This means I would have to wait almost 2 months. That is obviously frustrating since I can’t really do much without finished walls.

Now I’m wondering if it might be possible to lay the floors in advance and cover them properly.
The internet suggests using thicker milk carton paper (gray plastic sheeting), for example. Unfortunately, I have found very little experience regarding this. Otherwise, I could consider thick fleece or cardboard. My thinking is that the worker only applies relatively thin layers, so it shouldn’t cause a huge mess. Unfortunately, finding an alternative company is quite difficult. All other offers were significantly (at least 50%) more expensive. I would appreciate hearing about your experiences.
Best regards, S4z4

Is the screed already installed?

Yes, the screed is already installed. Except for the walls and the floor (laminate), everything is ready.
I just don’t want to have to wait two months idly for the plasterer.

I think at this point it doesn’t matter. Normally, the interior plaster should have been applied before the screed to create a sealing layer. Now it’s too late anyway.

Hmm, okay.
The question remains whether it makes sense to install the floors (laminate and vinyl) now if the plasterer will come afterwards. Of course, this is not ideal, but the question is whether it is possible and what your experiences as experts are regarding this.

Basically, it doesn’t make much sense to plan it that way, but it won’t cause any harm as long as you properly protect the finished floor, as mentioned. Of course, the plasterer might not like it. They need to work at the very bottom, so I’m not sure if it bothers them to have a 3mm (0.1 inch) protective fleece layer there. You should ask them. Alternatively, you could hire a different plasterer who works faster. Supposedly, there are more available again now due to many cancellations. I can’t say whether that beats the 8-week wait time.
