Question: Acrylic Underpainting, how long


Well-known member
How long is safe to wait til your acrylic underpainting has dried to paint oils on top?

Has anyone had any issues with oils not sticking after they've dried?
I paint on an acrylic underpainting as soon as it is dry to the touch. Sometimes I speed it up with a hair dryer. It's never been an issue.
Same here. As soon as it's dry where I can wipe my hand across it and make sure. Dry to the touch, like sno said. I've not had any problems with them not sticking. Just don't do it the other way around (acrylic over oil).
