Hello everyone,
we are currently building with a contractor, and I would like to ask about your experiences with the following issues:
1) It seems that many people struggle with rust stains on the ceiling. In our case, they appear sporadically on the precast concrete slabs, always circular (not elongated) with a diameter of up to 2cm (0.8 inches) and very dark rust-colored. Installing a suspended ceiling with drywall is not an option, as we need the full room height on both floors. The painter wants to cover everything with a sealing primer and not sand it down, saying that the rust comes from the rods inside the concrete slab. Do you think this will permanently conceal the rust stains? Are there better alternatives to cover these rust spots?
2) After the screed was laid, the house was briefly humid enough that permanent water stains appeared on the plaster. The painter also wants to cover these with sealing primer. I’m not really comfortable with this idea, especially since this is a new build and I don’t want to cover up and hide the problem or, worse, have to deal with the contractor’s mistake in incorrectly heating the screed. Are there alternative solutions for this issue?
3) The roller shutters have been installed, and it turns out the preparation work was poorly done. First, all the shutter tapes run very crookedly—they are not parallel to the window but instead angle downward away from it. This means the upper outlet and the box for the shutter tape are not aligned. Second, the upper outlet is set so deep into the plaster that the tape rests on the plaster surface. Is the only solution here to break open the masonry and reposition the box for the shutter tape? I’m getting a bit desperate.
Thank you in advance for your advice.

In any case, many thanks for the numerous quick responses! We will clarify everything with the painter and the surveyor.
