Product Description This watercolor ground from DANIEL SMITH allows you to use watercolors in bold new ways. Prepare any surface– e.g., plastic, cloth, tin, stone, etc.– to accept watercolor. This remarkable ground creates a soft, absorbent watercolor surface similar to cold press watercolor paper. You can use it to rescue or repair watercolor paintings, too.
