Mineral plaster instead of textured wallpaper?

Hello! We have a good general contractor offer that satisfies us in many respects. One point that does not convince us is that a textured wallpaper is used as the substrate + a double coat of paint. It is apparently a very solid solution... but it does not convince me. I would prefer lime or clay plaster. What are your experiences with textured wallpaper substrates? What alternatives would there be with a purely mineral (not synthetic) plaster? I look forward to your ideas and experiences :)

To what extent experiences? Or rather, to what extent does it not convince you? There is nothing to criticize qualitatively, you can live like this and I am not aware of any disadvantages. Whether you can aesthetically come to terms with it, you have to decide for yourself. Are there children involved? They like to pick off the bumps from textured wallpaper, on the other hand they also tend to quickly make stains on the wall, which in the worst case cannot be painted over. Some form of wallpaper (which can be peeled off together with the stains) is not the worst option.

Thank you very much for your feedback, Kekse :) Hm.. I think what doesn't convince me is primarily emotional: We have been living in an old building for a year. Almost all the walls here were covered with wallpaper, which made me feel uncomfortable. It seems to me that significantly more dust can accumulate there than on a plastered wall. So hygiene more than aesthetics. And also, that all wall and ceiling surfaces are covered with paste: I wonder how "healthy" something like that is?

Are there children involved? They like to pick off the lumps from woodchip wallpaper, but on the other hand, they also quickly put stains on the wall, which in the worst case can't be painted over.

Small children no, but dogs, who so far haven't managed to make stains on the wall (except in the entrance area, when drying). But I had to laugh a lot that children come up with such scratch games :D

Paste are adhesives in the form of an aqueous swelling product made from starch or organic cellulose ethers. They are usually methylcellulose. They consist of 2–20% renewable raw materials and 80–98% water. Paste sets physically by evaporation of the water; they cure cold and are easy to process.
From wiki

Children are given paste to play with in [kiga]. Therefore.

If you want plastered walls to have texture, dirt will also stick to them.

My tip for indoors. We apply a primer filled with quartz sand, watery and purely mineral, from sto, sakret, among others, onto the plastered wall. We roll it on and a second person has the ceiling brush ready and wipes a texture into the fresh primer in large semicircles. We let it dry. We then paint over it once with a dispersion paint of choice, done. Surely this is a misuse of the primer, but the result is very nice. And easy to do. Karsten
