I have already read a lot about lime, lime-cement, and gypsum plaster – I think clay is too expensive for us.
Some say gypsum plaster can be used, others say it must be lime plaster. The heating engineer we consulted criticized gypsum plaster as inert material. Our general contractor wanted to use lime-cement plaster everywhere but has now offered gypsum. It's a bit confusing. Should we insist on lime plaster? Does it really allow better breathability and improve the indoor climate? I would appreciate your living experiences.

We have gypsum plaster – which I wouldn’t recommend, especially if the walls are not going to be wallpapered. Gypsum is soft, so any dents become visible.
However, we didn’t really compare the two options afterwards, since gypsum plaster was used in our case. Maybe gypsum has some positive properties? Apart from the low cost?
If I say that mold tends to develop more easily on gypsum than on cement plaster, that might not be entirely accurate, but it’s probably not wrong either. I’m not familiar with the details, as I mentioned before... we just didn’t want to look into it further. But it could be a good reason to ask about it, look it up online, or trust the next person here who knows more about this.

Stefan Ruhnau20 Mar 2015 13:01Hello,
Usually, living spaces are finished with gypsum plaster at quality level Q2, which means the plaster is ready for wallpapering.
At this quality, the plaster is not suitable for painting because slight imperfections are immediately visible. In wet areas, lime-cement plaster is often used. This also serves as a base for tiles. I hope this information is helpful.

Stefan Ruhnau20 Mar 2015 14:53Hello, you can cover the gypsum plaster with a fiber fleece and then paint it. This works very well. In our region, the price for lime-cement plaster is about €14 per square meter (≈ $15 per square yard) and gypsum plaster costs about €12.50 per square meter (≈ $13.50 per square yard), including additional services. This is how the developers purchase here.
