ᐅ Mineral-Based Plaster Instead of Textured Wallpaper?

Hello!
We have a good general contractor offer that satisfies us in many ways.
One point that does not convince us is that textured wallpaper is used as a base, followed by two coats of paint.
It apparently is a very solid solution...
...but it doesn’t convince me. I would prefer lime or clay plaster.
What are your experiences with a textured wallpaper base?
What alternatives are there with a purely mineral (non-synthetic) plaster?
I look forward to your ideas and experiences 🙂

Lime plaster would be just right for us 🙂 Did you do it yourselves and did you have any experience with it? And if it’s more suitable for “advanced users”: is lime plaster a standard job for tradespeople, or don’t all of them do it? Also, are the labor costs similar to those for mineral-based plaster? (I understand lime is a bit more expensive—maybe the application process is also more involved?)

No, no, it was done by the plasterer. Honestly, I hardly know anyone who has done their own interior plastering (except friends who used clay plaster because they couldn’t find any tradesperson willing to do it...).
Lime was more expensive than lime-cement plaster in terms of materials. If I remember correctly, the labor costs were about the same. So, the application process is probably similarly (time-)consuming.

Thanks, Wickie!
And about the clay plaster... Hats off to anyone who manages to apply it themselves as a non-professional. I've heard it's more challenging than other types of plaster :-P

Applying clay plaster as a finish is quite simple. In our previous house, I used it to complete our bathroom (colored plaster can be purchased).

How lovely!
But... the wall looks nicely smooth. How is that done with clay?
I have a lot of questions because I would love to use as few tiles as possible 🙂
Is clay also suitable for wet rooms?
What kind of substrate needs to be present?

Thanks. It was a "normal" base coat plaster underneath. The clay plaster goes on top of that. It comes ready-made and is simply mixed with water. Then you apply it with a trowel and smooth it out. There’s no real difference compared to other types of plaster.

Clay plaster is actually ideal for wet rooms. It absorbs moisture quickly and slowly releases it back into the surrounding air. This helps create an excellent indoor climate. However, it is very expensive. For just the material cost of clay plaster, with other wall coverings you could easily include the labor cost as well.

Thank you, Nordanney!
I see we can’t avoid a "standard" plaster finish :P
