Hello,
In one bedroom, we will be applying glass fleece to the wall. Before that, it will be skim-coated with Knauf surface filler. Is it possible to paint this glass fleece with dispersion silicate paint (in our case Caparol Sylitol Interior Silicate), or will it not adhere properly?
Alternatively, we would only skim-coat the room (Knauf surface filler). Is this a suitable base?
Thank you very much

I wouldn’t use fiberglass fleece in the bedroom, as it’s not vapor-permeable and you generally don’t need that level of stability there.
What made you consider that?
Use regular painter’s fleece with 130-150 g/m² (4.3-4.7 oz/sq ft) instead. It is vapor-permeable and you can paint over it with any type of paint.
Silicate dispersion paint works well. It’s also vapor-permeable, highly alkaline, and therefore effective against mold.
The surface filler, in my opinion, is a gypsum-based filler. That would hold if primed first, but from my perspective, it doesn’t offer any advantage. It’s harder to apply as a DIY option than painter’s fleece, not alkaline, and doesn’t form a strong bond with the paint.
If you hire this out and have a sufficient budget, use lime-cement plaster at Q3 level finishing, then silicate paint. That is the most effective against mold.
Are you planning to do this yourself?

Hello,
I need to fill and smooth the wall because it is not even (not a new build). However, the unevenness is only in the lower millimeter range. Would it be okay to
Is glass fleece really not vapor-permeable? You can even blow air through it.
Thank you very much

- smooth fill with Knauf surface filler
- apply glass fleece wallpaper
- then paint with dispersion silicate paint

Hmm, are you possibly referring to reinforcement mesh?
As far as I know, glass fleece becomes diffusion-resistant as soon as it’s coated with adhesive and paint. I can’t rule out that there might be some products considered breathable (sd ≤ 0.5).
The question is, what do you expect to achieve with this in the bedroom?
When it comes to filling, it depends on whether you just want to level out minor unevenness (which is normal), or if you want to skim coat the entire surface to get a perfectly smooth finish ready for painting (which I wouldn’t recommend for a non-professional).
Sure, you can do this up there. But I’m skeptical about the usefulness of it.

I looked for the sd value in the technical datasheet but couldn’t find it, which makes me rather skeptical. It’s also quite expensive—more than twice the price of a basic renovation fleece.
Again:
What do you expect from using fiberglass fleece in the bedroom? Is there that much foot traffic there?
