Watercolor Ground. Creates an absorbent surface that allows for soft edges and flowing wet-in-wet techniques. May be brush applied for a linen-like texture, rolled on for a dappled effect, or scraped on smoothly with a palette knife. May also be lightly wet sanded for a smoothness similar to a hot pressed surface. May be applied to many different materials, including canvas and panel. Watercolor Ground dries to a lightfast, flexible surface that withstands repeated lifting and scrubbing.
