Wall covering - Aerated concrete Q2, painter's fleece and paint

Ok, all clear, then thank you! I will wait for now and decide afterwards.

So, here is the plan I have now: 0. Look at the result, possibly bring it to Q3. Wall treatment: 1. Tiefengrund LF (e.g. Vietschi) 2. Kleister Metylan NP 3. Glattvlies Vietschi 150 ([Ähnlich V150Pro von Erfurt aber nicht pigmentiert]) 4. 2 coats of paint with Caparol Indeko-Plus In the bathroom I’m not exactly sure yet, but probably like this (Kalkzementputz liegt an): 1. Tiefengrund e.g. Caparol FungiGrund 2. Glattvlies Vietschi V150 3. Mold protection paint e.g. Caparol Fungitex-W Opinions?

About the materials. Primer, take anything, the no-name brand from the hardware store is also fine. Here the price can be the deciding factor. Interior wall paint, Caparol is OK, but if you use Sto In, one coat will probably be enough. Professional paint, available online. Bathroom, I would do it differently. Rough unevenness fill with lime cement plaster, primer, then stick fiberglass, which comes from very coarse to very fine, depending on taste, then latex paint on top. This is how professionals treat wet rooms.

But Sto In only has opacity class 2, with Caparol it's 1. I want to paint twice anyway, because the fleece is not pre-pigmented and so I get an even seam appearance. I believe Caparol is higher quality, right? (unfortunately also significantly more expensive).

Thanks for the tips about the bathroom!

At least it is a very good color, just a bit overpriced in my opinion. But whatever.

ps I'm not a painter, but my brother is a master painter. You always get good advice from him.

Ok thanks, I have an offer for 75€/12.5L, I think I can live with that.
