These fluid mediums increase the transparency of the colors while enhancing adhesion of strongly diluted colors. They can be used alone or with acrylic colors to impart gloss, satin or matte sheen, and dry to a waterproof film that is flexible, colorless, non-yellowing, lightfast and age resistant. They are ideal for glazing, increasing transparency, extending paint, color blending, thinning and collaging, or even as a sealer and ground.
