White, opaque, matte and ground acrylic! Works well on canvas, wood, paper, metal, chipboard, fabric, plastic and more! Dries quickly. Works well for a variety of color products providing a smooth, non-yellowing, chalky background. Gesso is water-based, but permanent and flexible after drying. Will mix with pigments, or acrylic paints, to create a range of customized, colored grounds. Can be applied with a palette knife, texture tool or a brush.
