Opus Essential Gesso is an artist-quality gesso, perfect for preparing unprimed surfaces such as canvas, linen, wood and paper. This heavy-bodied, bright white gesso has maximum opacity, adhesion, and water-resistance, and dries to a non-yellowing, flexible matte finish. Opus Essential Gesso contains high levels of titanium dioxide, calcite grit, and acrylic resin. Apply 2–4 coats as desired.
