Inspired by the time worn charm of provincial antique furniture and artifacts, Crackle Medium marks any painted surface with the gentle hand of age.

Porter's Crackle Medium is an easy to use medium for creating antique and decorative crackle effects on furniture, walls, picture frames and other decorative elements.

Apply Crackle Medium to a previously painted surface, then, after a time, apply an acrylic paint (either Porter’s Ultra Flat, Eggshell or Low Sheen Acrylics).

As this finish coat dries, the Crackle Medium beneath causes the paint to split and crack, revealing the base coat or surface beneath.

Features & Benefits

Porter’s Crackle Medium is a clear medium that is designed for use in conjunction with other paints and finishes. The cracks will dry with a glossy finish. Water wash up. Apply by brush.
