ᐅ Applying silicate paint over painter’s fleece?

Hello forum,
I want to paint my kitchen (new build, calcium silicate masonry with gypsum plaster inside). I have applied Erfurt M120 painter’s fleece. Is it possible to paint silicate paint over this? I know it’s not the ideal substrate since the paint needs to chemically bond with the wall, so the proper effect might not actually occur. Still, I believe silicate paint would allow better breathability than dispersion paint in this case?

Good luck, Frank

Silicate paint only works on mineral-based substrates, precisely due to silicification.

This paint does not cure at all on fleece, so it is not suitable.

Regards

Thank you very much,
the painting has already been done. I applied the paint myself, but there were stains. A painter told me to sand off the silicate paint, then apply a deep primer LF, and finally paint again with regular dispersion paint. Would this be a reliable solution?

Good luck, Frank

Try washing it off as a test?

The purpose of the primer is to even out absorbency; fleece does not absorb, adhesion should improve, and dispersion paint already has it anyway. So why use a primer?

Once the silicate paint is removed, I would apply two coats of good-quality dispersion paint.

Regards

Yep, I would follow the painter’s advice, but without using primer. To make the emulsion paint washable later in the kitchen, you can treat it with wallpaper protector. It is washable and breathable.

Thank you, that makes sense. However, the silicate paint is not completely removed, just sanded down as much as possible. I will give it a try.
