Instructions
Paint over the surface of the painting with crackle medium. This gives the painting the appearance it cracked slightly over time, with age and sun exposure. Allow the paint to dry for 30 minutes.
Apply a thin layer of amber-tinted glaze over the painting with a paintbrush. Leave some space under the glaze for the original color of the paint to peak through. This gives the painting a more authentic appearance. Allow the glaze to dry at least two hours.
Apply a second layer of glaze to seal the painting. Use clear glaze this time, to avoid making the painting too dark or dull to see. Allow the painting to dry overnight.
