How to further process cement plaster in the bathroom?

Good evening everyone,

the interior plastering work has been completed by us. The main bathroom was plastered with cement plaster.

Only the shower and 1.25 m in the other wet areas will be fully tiled.

Now the question arises for us, how to treat the rest of the plaster?

How did you solve the “problem”? Who has a good tip for us?

Best regards

Eve

Yes, we have thought about that too.

We are also aware that it needs to be pre-treated.
Unfortunately, the specialist trade is not in agreement on this. Hence the question: How did you do it?

In the areas where there are no tiles, we had a very fine premium plaster applied and partially painted it to set a color accent.

That it needs to be pretreated is clear to us as well.
Unfortunately, the specialist trade does not agree on that. ?

About what? About the design or the pretreatment?

Yes, we thought about that too.

Had Q4 plastered and then painted "normally" (Caparol Indeko Plus + wall tattoo to set accents).

About what? About the design or the pretreatment?

Both. That is what's called a specialist retailer. One of them told us we could wallpaper the bathroom with fleece wallpaper, as well as the rest of the house. When I asked him where the moisture was supposed to go, he just shrugged. In our experience, fleece is not suitable if the walls are not properly dry yet. Surely there is still moisture inside when moving in, right?
