PaperArtsy Crackle Glaze provides a crackled effect between two contrasting colors of paint. The high contrast in colors is important so you see the bottom color through the cracks in the top one.
Apply the first color and allow it to dry. Shake the bottle of Crackle Glaze to ensure it’s well mixed, then apply a thin layer and allow it to dry too. You can use a heat gun to speed up the process. Apply the second paint color on top of the dry Crackle Glaze. As it dries, the reaction between the second color and Crackle Glaze will allow the cracks to form.
