Can I put acrylic paint over DRY oil paint?

Im confused about this. Obviously you cant if its wet but what if the oil is dry, will the acrylic hold?Can I put acrylic paint over DRY oil paint?
You have not described what this is. Are you thinking of a painting? Is this on some form of craft project and what is the material support (surface material being painted) ?





This is not good practice. You can put oil over acrylic but should generally avoid acrylic over oil unless this is something you don't care whether it lasts or not. Generally, oil should go on oil and acrylic should go on acrylic.





Acrylic is not rigid as one post above states. Though it is plastic it is flexible as many forms of plastic are flexible. Oil is more brittle than acrylic. When acrylic paint dries you can peel it off a smooth surface and it is like rubber.





Oil needs to be handled with care even when placing oil over oil. Layers of oil should increase in the proportion of oil they contain with thinner, less oily, layers under thicker and more oily layers. This is due to the manner in which oil paint oxidizes. You have to account for each layer's drying characteristics. If this is done incorrectly the top layers will wrinkle and crack.Can I put acrylic paint over DRY oil paint?
Of course you can. I definitely suggest priming it first. One coat of primer should do fine, then 1-2 coats of paint. You can ask anyone in the hardware store you buy your paint, they're all usually experts at it. At least the one I work for.
its posible, as long as the oil application is thin, if its too thick, the surface might be too shiny for acylic paint to stay. but dry on dry is ok.
No! Oils even when dry always moving. Acrylics are plastic and become rigid. You would end up with problems down the line.
