Gesso can be thought of as the bridge between your support (canvas, board or whatever you paint on) and the paint. Golden Gesso is designed to penetrate supports and provide a surface to which paint can adhere. It is formulated to be flexible and is highly pigmented for greater opacity. Proper preparation with Golden Gesso increases the life span of artwork.
Sandable Hard Gesso is formulated with 100% acrylic polymer emulsion and can be sanded to provide surfaces that are smoother and more even than those created using regular gesso.
