How Do You Finish Over Acrylic Paint?
You can finish over acrylic paint using an acrylic varnish for protection and enhancement. However, the best approach depends on your desired outcome and the type of acrylic paint used.
There are several ways to finish over acrylic paint, each offering different benefits:
-
