Filigrandecke or exposed concrete

A cast-in-place concrete slab does not look different from a filigree slab - the price is usually similar, but the effort is usually avoided.

Thanks for your answers, I want to avoid plastering and painting and wallpapering is out of the question.....

According to offers from several shell builders, the in-situ concrete ceiling costs quite a bit more than the filigree ceiling.

Any more ideas?

Have a nice evening, Wolfgang

Why should the ceiling be more expensive? It was cheaper for us, easier for the electrician and the controlled residential ventilation builder, and it also went faster since we were not dependent on delivery from the concrete plant. Of course, it involves more work for the shell builder.
The ceiling is then seamless and does not consist of different parts whose joints also have to be filled (this is important for you if you want exposed concrete).

Hello,
how have you decided now?
What speaks against leaving the filigree ceiling final?
That is at least my plan. Of course, one must think in advance about the arrangement of ceiling outlets for pendant lamps or spots and plan that with the shell construction worker. But is the appearance of the untreated filigree ceiling not acceptable? Has anyone done it that way and maybe has photos of how the look is?

And leave the joints like that too?

You can see it if it hasn't been filled.

Yes! I don't know if I'm completely off track here, but it's purely a matter of visual preference when you finally see the joints, right? Either I can't find any photos of how it looks or simply no one does it because it has to be leveled and filled. From what I keep reading, most of the crookedness occurs during the leveling, filling, and sanding, and the appearance later is not as desired. Or is it important for other reasons to close the joints?

You definitely have to fill and sand and fill the joints - especially with [Streiflicht] it otherwise looks strange. Completely untreated would mean gray mottled... yes, of course, it's a matter of taste, but I found this step from gray to white already nice and satisfying.
