Which primer and which paint are suitable for gypsum plaster in new construction?

Hello dear home builders,

the thread title already says it: The plasterer will soon start plastering the walls of our new building with gypsum plaster. He said I have to sand off the sintered layer, prime it, and then paint. Clear so far.

Which primer should I use for something like this?

Which paint is suitable for this? So far I have read online that dispersion silicate paints or lime paints should be used because they are vapor permeable and maintain the climate-regulating property of the plaster...
The plasterer told me today "lime paints don’t work" and "I can also use any normal interior paint like Al**na white...". So what is correct?

Regards,
kirsel

We applied a silicate-based primer and then painted over it with silicate interior paint. It worked great, but it really wasn't cheap (which I would anyway advise against for a private home). I don't know what else works and what should be avoided in connection with gypsum plaster.

Please tell me which products you used. Thanks!

a these are diffusion-permeable and maintain the climate-regulating property of the plaster...

The gypsum plaster is rather not diffusion-permeable.

We painted the entire house with Caparol Indeko Plus. We used various primers (brand name products to no-name ones from the hardware store). The end result is identical everywhere. Only with the paint did we pay attention to quality - it is also damn... expensive. Some painters also used Caparol at the neighbors.

What is your opinion on the two theories mentioned in the first post?
Which color type is suitable for gypsum plaster and which is not?
