How long does it take for thick oil paints to dry?

I have made a poster using pencil and white-out for the main villian of my book, and acyrlics and marker for the background about five years ago. I am painting over the background with very thick oil-paints to add a vibrant look. I am trying to give a slight 3-D impression, but for the sword I want to paint over the thick oil paint with metallic acyrlic along with other area's. I just want to know how long I should give the oil-paint to dry with area's as thick as 3 to 4 mm. Thank you for your help!!How long does it take for thick oil paints to dry?
Oil paints can feel ';dry'; after a few days, but they can take weeks to ';cure';. Oil paints dry by oxidation - meaning oxygen must reach the deepest layers in order for it to dry. A layer of 3 to 4mm may take over 4 weeks to fully cure.





This is one of the reasons acrylics cannot be used on top of oils - they dry much faster and do not allow the oil beneath to oxidize and cure properly.





You would have much better results using a pasty mixture of acrylic paint and acrylic gel for the textured area, which will cure in about 24 hours, then paint over that with your metallic paint with great results.How long does it take for thick oil paints to dry?
You can paint over acrylics with oil paint but I think you will have a problem painting over oil paint with metallic acrylic which is water base. I think it would crack off after a while. Try using a metallic oil base paint instead. Then you won't have to wait for your oil paint to be that dry, just dry enough to paint over with out blending in with the metallic paint.





Good Luck!
several days, check randomly, and wait until at least touch dry before adding other paints,

The answer depends on what part of the country you live in are you in a cold %26amp; dry climate or a humid one? Anywhere from 1 to 3 weeks. you will know when its not sticky.
