Is it safe to paint a layer of acrylic on a canvas and then when dry paint with Flashe vinyl paint over the top?
Hello there,
Mostly yes,
In extreme cases it depends also of the kind of acrylic, the thickness of these previous layers and the kind of flexible stress the art will suffer.
I’m saying that because flashe paints are less flexible than common acrylics. So if you put your slightly rigid flashe over a great thickness of very soft acrylic, and then start rolling and unrolling your canvas, you’re likely to get cracks of the flashe.
To some extent if you’re familiar with it, it’s also a ‘fat over lean’ rule (flexible over less-flexible)
It’s an extreme case risk though, flashe have some flexibility as well, just not as much as common acrylics. It’s unlikely to happen in most ‘normal’ situations and uses. Just be aware of it.
But adhesion and compatibility is expected to be good.
Good painting to you,
Lussh
