Hello everyone,

I am currently planning the interior finishing. The walls will be handed over with Q2 plaster.

My idea is as follows:
- Smooth the walls as much as possible, but without too much effort
- Apply painter's fleece on top (Erfurt Variovlies V180 or V200S)
- Then paint with Brillux paint

What do you think? I would apply the adhesive to the wall and then stick the fleece edge to edge.

I would appreciate any feedback.

Alright, thanks everyone! I will wait for now and decide afterwards.

Here is the plan I have so far:
0. Review the result and, if necessary, bring it up to Q3 standard.

Wall treatment:
1. Deep primer LF (e.g., Vietschi)
2. Paste, Metylan NP
3. Smooth fleece Vietschi 150 (similar to Erfurt’s V150Pro but unpigmented)
4. Two coats of paint with Caparol Indeko-Plus

For the bathroom, I’m not completely sure yet, but probably like this (lime-cement plaster is present):
1. Deep primer, e.g., Caparol FungiGrund
2. Smooth fleece Vietschi V150
3. Anti-mold paint, e.g., Caparol Fungitex-W

Any opinions?

Regarding the materials. For primer, use anything available—even a generic brand from a hardware store is fine. The price can be the deciding factor here. For interior wall paint, Caparol is acceptable, but if you use Sto, one coat will probably be enough. This is professional-grade paint, available online.

As for the bathroom, I would approach it differently. Fill large uneven areas with a cement-lime putty, apply primer, then install fiberglass mesh, which comes in a range from very coarse to very fine, depending on your preference, and finally paint with latex paint. This is how professionals treat wet rooms.

Sto In, however, only has a coverage class of 2, while Caparol is class 1. I’m planning to paint twice anyway, because the fleece is not pre-pigmented and this way I get a uniform seam appearance. I think Caparol is higher quality, right? (Unfortunately, it is also significantly more expensive).

Thanks for the bathroom tips!

At least it’s a very good paint, although I find it somewhat overpriced. But never mind.

ps I’m not a painter, but my brother is a master painter. So you always get good advice.

Okay, thanks. I have an offer for €75/12.5L (3.3 gallons), and I think I can live with that.
