Hello,
The plasterer will be coming in the next few days, and the more I read about it, the more confused I get. May I ask about your personal experiences, especially regarding indoor air quality and surface texture?
Standard for me is a lime-cement plaster, but gypsum plaster was also offered as a cheaper alternative. Now I have read about lime, lime-gypsum, gypsum-lime, or something similar. I’m feeling a bit lost.
Thank you very much.

Thank you for your response.
Is there a base coat and a finishing coat when applying lime plaster or lime-cement plaster, or is the plaster applied directly in a single layer onto the wall (in my case, hollow brick)? In our case, a base plaster was applied.
In the basement, garage, utility room, and attic, we used MEP (lime-cement plaster), and in the living areas, etc., we used red lime (lime base plaster).
Afterwards, a 1-2mm (0.04-0.08 inch) lime finishing coat is applied, depending on the desired final surface (there are also different textures or smooth finishes available).
We opted for a 1mm (0.04 inch) grain lime finishing coat.
For the aerated concrete exterior walls, it was important that we sprayed on a primer to prevent the plaster from drying too quickly and possibly causing the surface to blister.
A 1:6 dilution was sprayed using a pump sprayer.
By the way, the spraying took about 5-6 hours for the “geht’s Haus.”
