Moisture?

I'm currently living in Switzerland and renewing the basement of a 100-year old building.
There's this kind of sink made of massive stone.
Every time I paint it, the paint starts to crack after just a couple of days and some kind of hair appears.
The sink is at least 4 inches thick at this place, but would you say it's possible that moisture travels through from the inside or is it more some kind of mold living on the outside?

Thanks

With paint a lot hinges on the preparation. How did you clean and prepare the sink for painting?

The type of paint you use also makes a big difference, especially in a wet location like painting a sink. What paint did you use?

Improper prep or wrong coating is the most likely cause.

Just universal dispersion.
I'll give it a try with more prep.

universal dispersion
Can you further explain that? I'm not familiar with that term in painting.
DIY sink and tub painting is iffy at best. You need to use a paint that is tailored for that use. Like a tub and tile paint.

Yes, sorry.
They call "dispersion" any wall paint here in Switzerland.

It sounds like you are using a water based latex wall paint. That will not work on a sink, as you are seeing.
