Hello,
I have lime-cement plaster throughout the entire house and want to start by painting everything white, possibly adding some accents after moving in.
The idea is simply to paint everything white first or maybe use wallpaper.
What have you done with your lime-cement plaster? Is it worth using silicate paint, or is the difference in indoor climate compared to an emulsion paint rather small? What should I pay attention to?
Does anyone perhaps have experience with wallpapers?
Many thanks to you all

Whether you dilute the primer or use the TG, it doesn’t matter. Both the TG and the primer are meant to achieve the same result. You can also dilute with water.
The goal is to prevent the substrate from absorbing too much, so that the topcoat provides a uniform finish without appearing patchy. That’s the main point. The paint won’t peel off the wall even without a primer. What is useful for new plaster is to lightly sand it once, because during curing and drying, it forms a sintered layer on the surface that paint adheres poorly to. Karsten

Karsten I would sand, prime, and apply the paint with an airless sprayer. It looks great and the equipment isn’t that expensive.

Marvinius. The questioner seems to be able to tell brushes from rollers. And you’re talking about spraying.I’ve heard a lot of different opinions, so I’m a bit unsure. Recently, a painter told me that you should only remove the bumps with a scraper, but never sand the plaster (in his opinion, sanding would show after painting). Another person, however, strongly recommends sanding.
So, maybe both are correct.
The problem: At the top of the ring beam and in the corners, the plaster dries very poorly and forms this sinter layer, which also hinders drying. I lightly sanded these areas by hand with fine sandpaper, which resulted in those spots drying properly and turning white. For the large wall surfaces, we only removed bumps with a filler and filled in spots where the ladder or something had bumped against the wall.
I think the sanded areas are not noticeable.

I don’t quite understand—what exactly did you use to fill the lime-cement plaster (LCP)? We have the same setup. We have LCP in the wet rooms. It was applied as a base coat by the plasterer. I’m struggling with how to proceed now. I’d also like to just fill and sand, but I’m not sure with what material and then apply the paint.
How was your LCP prepared before painting? Was anything applied on top of the base plaster? Did you also just fill and sand, and if yes, with what material?
Thank you all 🙂

The classic approach: gypsum plaster in the living areas, and lime-cement plaster only in wet rooms. That’s how most people do it. Since my brother is a master painter and therefore professionally qualified, I’ll share what he did with me. Bathrooms and kitchen: We didn’t want too many tiles for aesthetic reasons. So, walls were filled and sanded. In the kitchen, where there was gypsum plaster at Q2 level, only the hollows were filled.
Then a primer (Tiefgrund) was applied. On top of this, fiberglass mesh was glued, Sto Tex. Then StoCryl Semi-Matte paint was applied. Commonly called latex paint, but ultimately it’s an acrylic paint; genuine latex rubber paint is apparently no longer available on the market.
The result is scrub-resistant, washable walls, similar to tiles.
All other rooms: hollows filled, primer coat (Stosil Putzgrund) rolled on and a textured pattern brushed in with a ceiling brush. This product fills unevenness and is a great base for wall paint.
On top of that, tinted wall paint of my wife’s choice from Renovo. Ceilings, after filling, were all painted with Stobasic in an off-white shade.
After several coats, any other paint peels off.

We painted the lime-cement plaster with interior silicate paint (permeable to vapor).
Two coats were necessary without primer.
