Aqua Fix can be mixed with watercolor paint in lieu of water or applied over a watercolor wash. It makes the surface waterproof and allows successive washes of color that do not disturb one another — colors remain clean and vibrant. This product has a slightly milky appearance but dries clear. Some artists have found it useful for application over watercolor painted on canvas in order to preserve and protect the surface. Wash brushes and palette immediately after using Aqua Fix.
