Can acrylic paint be used to paint a mural on top of a wall that has been painted using oil based paint? I am painting my room blue with oil paint and i want to paint some planets and stuff over it with acrylic,but the wall itself is being painted with oil paint.
You CAN paint acrylics over a wall painted with oil paint IF you sand the area once it's dry, and apply a good household primer (from the hardware store) that's meant to cover oil paint. The labels will tell you which one works best. To sand just the area you need, tape around the shape with masking tape - use a couple of layers so you don't sand through. Or - just repaint the areas you've sanded after your planets are painted. Lastly, there's no reason you couldn't paint your planets in artists' oil paint.
