Crackle paste is a white, light-weight ground made with a unique balance of solids and acrylic binders. It’s use results in an intentional controlled failure that causes the material to develop cracks as it dries. This product allows the artist to introduce a random, cracked look which can imitate an aged surface, like that seen on old frescoes or antiques. The cracking is random but can be influenced somewhat by the thickness of the application. This ground can be tinted with acrylic color before application (up to 10% by volume) and can be painted, glazed or stained with color once dry. This product performs best on a rigid support which is primed with an absorbent undercoat such as gesso, high-load color, or even house paint. The directions on the package should be followed. Tools clean up with water.
