ᐅ Wall construction on lime-cement plaster (healthy indoor environment / mineral-based)

Good decision, latex paint is really an eyesore (and also unpleasant when you regretfully want to remove it from the wall). By the way, when our cat was very ill, she soiled the hallway walls with vomit and very loose stool, and both could be completely cleaned off the dispersion silicate paint used there with a damp microfiber cloth. So, ordinary dirt from a wet dog or similar shouldn’t be a problem.

Thank you, your advice reassures me a lot. My Rottweiler lady is like a bull in a china shop, so dirt on the wall happens quickly.

felt-like appearance of painter’s fleece.

I agree with Tolentino. With painter’s fleece, the wall looks plastered and perfectly sanded. You can’t even tell there’s anything on the wall.

Besides the indoor climate

The large amount of fleece does not affect the indoor climate. It simply can’t. It’s like it’s not even on the wall. It is completely vapor-permeable.

But it would also depend on trying whether you can cut out a large piece of painter’s fleece, reattach it, and repaint over it

That’s exactly how you can do it. The difference you might notice comes from the paint, which may look different than the paint already on the wall for two years. If you repaint the entire wall, it won’t be noticeable anymore. But that applies to any surface.

I think there’s often some misunderstanding because the term painter’s fleece unfortunately refers to many different things (it’s even used for floor protection fleece). I’m talking about proper heavy-weight (150g/m² (4.4 oz/sq yd) and up) cellulose-based fleece that is vapor-permeable and perfectly smooth to the touch. In my opinion, after painting it simply looks like a smooth wall. Any surface texture then comes solely from the paint roller.
So accidental scratches and the like generally don’t get through this kind of painter’s fleece. In my house, I also rarely drill holes in the walls just to end up with nothing on the wall afterward.
But yes, I think you’ll probably notice a patched area more than on a wall that’s already completely skim-coated. Though it could be worth trying whether you can cut out a large piece of the painter’s fleece, re-adhere it, and repaint it seamlessly. In any case, the seams of the fleece strips aren’t visible after painting.

Yes, that’s probably it—qualities labeled as “painter’s fleece” vary so much that the results can differ widely. Personally, I may only have seen low-quality or poorly applied painter’s fleece so far (both in this rental apartment and in a newly built house where it was still fresh and unused). Here, I can clearly see where holes were filled even though the wall has been completely repainted since then (by a professional, not the previous tenant herself). In the new build, the appearance wasn’t bad, but it still didn’t look like skim-coating to me. The texture was definitely not from the roller but came from the fleece itself. But that may largely depend on the exact material used.

For me, a wall must be able to have holes made and patched without the repairs being visible afterward. For example, we have quite a bit of artwork on the walls that we like to swap, rearrange, or change frames for, so this happens quite often.

That’s obvious, and it doesn’t even have to be two years apart. Spot touching is almost always noticeable, even if the paint has only been on for a week. But nobody who cares about well-painted walls does spot fixes. You usually have to paint the entire wall up to the next corner or door frame. As I said, the mentioned wall was fully repainted, yet you can still see it. It’s a texture issue, but maybe that doesn’t happen with every painter’s fleece.

Definitely not. They probably used some cheap (thin) material with texture, which allows for a low price per square meter (square yard) and still hides unevenness in the wall. That approach is quite similar to the traditional woodchip wallpaper.

What I and @nordanney are referring to is a different matter altogether.

Thankfully, it’s not as bad as textured wallpaper, but I can absolutely imagine that cheap was chosen instead of good. Do you know which type of painter’s fleece was applied in your case (or yours, @nordanney)? I’m happy to give it another chance if there is a significantly better quality available than what I know so far.

Which painter’s fleece was used – if known – in your case (or yours as well, @nordanney)?

I can’t really tell you for my last apartment. It was a "no name" fleece with 150 or 180 g/m² (4.4 or 5.9 oz/yd²).
Currently, I am redoing my entrance hall at home. For that, I bought Erfurt Variovlies V 180 Pro.
