ᐅ Non-woven wallpaper on the walls – which type to choose?

Hello everyone,

I have a question about wall finishing that I’m unclear about. I agreed with the painters on a Q3 level finish, a fleece, and a silicate paint. They haven’t started yet, but they have already delivered several rolls of glass fleece to the construction site.

I wasn’t expecting that; I thought fleece was made from cellulose or similar, so I’m a bit surprised. I will ask them about it, but I wanted to get your input first. Is this standard practice? What is the professional view on this?

Thanks, regards
GD

Unfortunately, you are asking the wrong questions.
What was agreed upon in the contract? Because fleece can mean many different things — painter’s fleece, fiberglass fleece, jointing fleece.
And how is the fleece supposed to be applied? On the finished Q3 wall, or embedded in the plaster, then sanded and painted?

All the options I mentioned are possible and professionally acceptable, even standard. The real question is what you commissioned. Saying “put fleece on the wall” basically leaves all options open for the contractor. A clear instruction in the contract would be something like: “Plaster the wall, apply joint compound to Q3 level, sand, then adhere painter’s fleece weighing 220g/m² (6.5 oz/yd²) and paint with white silicate paint Sto Schlagmichtot.”

Thank you, Nordanney – yes, I’ve just checked it now...
Well, I’m more of a lay expert, and after asking around and searching forums, I decided on fleece without realizing there are so many different types.

The painter plans to fill it, sand it, apply filler twice more, and then use mineral/silicate paint from Keim. He says this method keeps the surface most breathable since we have lime plaster.

I had only thought of the classic painter’s fleece, applied with adhesive to the smooth wall and then painted over –
but I find the version offered now more elegant (just my lay opinion).

Then it’s probably more like a mesh, right? Otherwise, I would say that fiberglass is not vapor permeable... But yes, I wouldn’t put painter’s fleece over lime plaster either...

But yes, with lime plaster I also wouldn’t stick paintable fleece over it…

Sort of — it’s not the typical mesh with small squares but rather a fleece made of irregular mineral fibers. I’ve seen it; it’s very thin, almost transparent. Apparently, you can paint it directly, but that’s not really my preference.

So, a fiberglass mesh tape. Personally, I think it’s the best solution. Look forward to a great wall that only needs to be painted and still won’t show the usual cracks.
