Is there any medium that an artist can paint using watercolor over oil or acrylic intermixed?

I like to build on a sketch as I experiment as I go?Is there any medium that an artist can paint using watercolor over oil or acrylic intermixed?
It's usually not a good idea to use water based paints over oil (doesn't matter how dry the oil is), oil and water don't mix and the acrylics will ultimately crack and flake.


The other way round is fine, oil over acrylic works and has been used many times.


A few artists have used small amounts of watercolour over oils (Turner was one) and these paintings now give picture restorers nightmares.


As far as I know there is no medium for this purpose.


But if it's really what you want to do then who can say no?Is there any medium that an artist can paint using watercolor over oil or acrylic intermixed?
I don't know of a medium that allows you to work wet-on-wet with oils and any other medium. If you can afford to sacrifice a canvas and at least one brush, you can experiment with mixing the two mediums on a canvas and see what you get for results. It may take a couple years to see how it works with the way you use it, but it could be an interesting experiment.





I have been experimenting with acrylics over dry oil for a couple years now with no problems. It might be a hundred years or more before we know if it flakes off or has other undesirable effects.
dont see why not,though id use watercolours last


buy some spray paint too
that would be sloppy
