Liquitex - Acrylic Surface Prep - Clear Gesso - 32 oz - Surface Preparations are used to seal, prime and add tooth (for color adhesion) to all surfaces such as canvas, wood, paper and metal. This same preparation is used for both acrylic and oil paint. Our professional gessoes usually take just 1 coat. Liquitex Clear Gesso is a very clear size and ground that keeps the working surface visible. Clear Gesso provides an ideal degree of tooth for pastel, oil pastel, graphite, and charcoal as well as an excellent ground for acrylic and oil paints. This gesso is ideal for painting over colored or patterned surfaces or over an under drawing. Mix with acrylic color to establish a tinted transparent/translucent ground. Dries clear to translucent depending on thickness. One coat is usually enough.
