Crackling paint is a great technique that can be achieved in a few different ways. We have highlighted what we think are the two most achievable and consistent techniques. The first involves a white glue and the second uses a commercial product. As you can see from the side-by-side demonstrations, both produce wonderful results.
Apply white school glue to half of a painted surface.
To the top of the glue apply a layer of paint or wash. Allow it to dry completely.
Apply commercial crackle to the other half of the painted surface. Allow it to dry completely.
This view allows you to see the differences in the crackles prior to shading.
To shade the commercial crackle, apply a thin layer of paint or watercolor crayon and work it into the crackle using a soft cloth or baby wipe.
Work the shading into the crackled paint created with white school glue.
