ᐅ Should you use lime-cement plaster or gypsum plaster for interior walls?

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?

Both approaches have their merits.

For me, it's all about the climate.

In our current rental apartment, the bathroom has a lime-cement plaster. Attached is a photo. Our construction coordinator showed us this plaster in one of his apartments for living areas as well. There, the texture was not as coarse, and we liked it. Therefore, we will probably choose lime-cement plaster for the entire house. If the kitchen is not considered a wet room in terms of humidity levels, then I don’t know what is. Boiling potatoes for 30 minutes produces as much humidity as a 10-minute shower.

In winter, the air is usually too dry anyway, so it absorbs the moisture—not the plaster. And in summer, the windows are open. So what? A kitchen is not a wet room because of that.

Everyone is entitled to their opinion. Your reasoning applies to the bathroom as well. Or do you only consider it a wet room if you can walk through it with a hose like in a butchery?

The fact is, a kitchen produces moisture—and not insignificantly. It ranks second right after the bathroom, followed by the bedrooms, then the living areas, and finally the storage spaces.

Putting moisture and plaster issues aside for a moment: we like lime cement plaster. It may be more expensive upfront, but overall, due to its easier, faster application with less rework involved, it is more cost-effective than lime gypsum plaster. Additionally, this plaster masks minor imperfections quite well.

In the bathroom, you may have splashing water, and if you take a long shower, you use about 200 liters of hot water. So, in my opinion, comparing the bathroom and the kitchen is not realistic. When I leave the bathroom, I can no longer see anything because of the steam; I have not experienced that in the kitchen.

Regarding water consumption, I strongly recommend using water-saving showerheads.
I just looked it up out of curiosity—5 minutes of showering uses about 50 liters (13 gallons) of water on average. That’s quite a lot.
