 How can I achieve a layered effect with Art Resin? There is no limit to how many layers you can stack one on top of the other of Art Resin. And the fun thing that you can play with is actually adding artwork in between those layers. So you could do collage, you could do paint marker, you could do acrylic paint, whatever your heart desires. You can even embed objects once your last layer of resin has cured for about three to four hours and is still tacky. But if you want to paint on the resin you should actually wait for about 24 hours till it's completely dry to the touch. So as you layer coat upon coat it gives a 3D effect much like a shadow box.
