Can I Use Acrylic Paint Over Oil Paints?
It is safe to use oil paint over acrylic paint, but if you think about applying acrylic paint over oil paint, then it cannot be a good decision. Oil and acrylic are used for paintings, but acrylic paint is not suitable for oily surfaces. So, what you want is the wrong method.
Acrylic is plastic. So, you cannot say when it becomes breathable and when not. An old car emits gas. Acrylic paint will crack and flake because the gas escapes if you paint it on top of the oil.
Can I Apply Acrylic Paint on Oil Alkyd?
You can use automotive acrylic paint over oil alkyd, but you must accurately cure the oily surface. When the oily surface is cured, re-paint with acrylic paint or oil-based paint, and you don’t face any problems. Now how do you know the oil-based paint is completely cured? After curing, it becomes so hard, and you cannot eliminate the finish even if you scrub. It takes almost 10 days to be fully cured.
But don’t dare to use acrylic over the uncured oily surface. Otherwise, acrylic paint will crack the top coat. Then you have to start the painting from the beginning. On the other hand, alkyd paints that have not yet healed can be safely painted with alkyd or oil paints without fear of cracking the top coat.
