Hello, we are currently trying to decide whether to use lime-cement plaster or gypsum plaster in the living areas.
Gypsum plaster is cheaper and results in a smoother wall. However, we are leaning slightly towards lime-cement plaster because it is said to be more impact-resistant and to improve the indoor climate.
Everyone recommends something different :-(
Are there any people here who have lime-cement plaster in their living areas and can share their experiences?

Plaster is the usual choice, probably more for cost reasons. In my opinion, lime-cement plaster is of higher quality but has a different texture, which can be quite appealing. It is moisture-resistant, but that doesn’t make it the exclusive “wet room plaster.” It’s simply a positive feature—or a negative for gypsum plaster (as is its sensitivity to impact).
I won’t comment on any so-called indoor climate gurus.

Due to various energy-saving regulations or mechanical ventilation requirements, recirculating range hoods are often installed. While the potatoes are simmering, the steam moves around the living room. Gypsum plaster can swell. Lime-cement plaster does not.

Gypsum plaster can swell. Lime cement does not. Clay plaster does not either. Lime as well... but both are probably in a higher price category – and also more challenging to paint.

So gypsum plaster does not swell just from potato steam. There would have to be more moisture involved. A kitchen is not considered a wet room.
