Hello everyone,
I have a question for the building experts regarding interior plaster. Unfortunately, we have not yet found a well-founded opinion on this.
In our preliminary building specification (contract not yet signed), it states that the interior walls are to be finished with gypsum plaster.
When our building plans became more concrete, I also got some literature. From the book "(K)ein Pfusch am Bau: Wie ein Bausachverständiger (s)ein Haus richtig und dennoch kostengünstig bauen würde“ by Günther Nussbaum-Sekora (which I find really good as a layperson), the following quote:
[ I]Due to my inquiry (note: building surveyor), the building quality could already be improved before the first ground-breaking.[/I]
[ I]According to the building specification “interior plaster machine application”[/I]
[ I]What was meant was the cheaper and moisture-sensitive gypsum plaster. It was upgraded at no extra cost to lime plaster. The high pH value of lime (>12) prevents microbial growth.[/I]
End of quote
In addition, we will be building with Ytong blocks and installing a ventilation system.
So now my question to you is:
Does anyone have experience with this?
Are there other aspects besides microbial growth that would speak for or against lime plaster? (e.g. problematic texture, more difficult application or finishing, paintability, wallpapering issues, moisture sensitivity, or similar)
(where I understand the purpose of lime plaster is to absorb moisture better)
If you support using lime plaster, would you use it throughout the entire living area as interior plaster or only in wet areas (bathroom, kitchen, utility room)?
If my assumption is correct that lime plaster absorbs moisture better – does this still make sense if a ventilation system is installed that already removes room humidity?
Thank you very much for your answers

We also have plaster on the walls in our old building. How can I find out what type it is without doing a material analysis at a technical institute somewhere?
By the way, gypsum plaster can be painted with lime paint...
Sebastian, why did you not want that, or why did you choose lime-cement plaster instead of pure lime plaster? Is lime-cement plaster visually better than pure lime plaster? Or is it cheaper or more expensive?

People will not be satisfied with plaster applied quickly and cheaply by the construction company if it is the wrong type of plaster on the right substrate and cracks appear or the plaster starts to detach. It is not about subjective impressions or carelessness, but about a structurally and physically correct application of the materials.
Most companies do not give this much thought either, because they only "know that one type of plaster"; private builders have even less expertise and "don’t notice anything" until the building damage may become severe. Just because something has "always been done that way" does not mean it is always correct. It is well known that there is a tendency toward collective error.

You get cracks in the plasterboard (KZP) quickly anyway – but they are not necessarily a problem (as long as you know the cause).

It was definitely quite a bit more expensive Could you possibly tell me what you paid for lime plaster? My preferred plasterer wants 18.00 €/sqm (per sq ft) net!
Unfortunately, only the additional cost was covered – it was handled through the general contractor but before signing the contract. The extra charge was about €8 per square meter (approximately $8.70 per square yard) – which only helps to a limited extent. It could be that the plastering company was very cheap and did poor work. Likewise, it could be that the current company was very expensive because they have a good workload. It’s difficult to compare like this.
I am still satisfied because the result convinces me.
