Used as a medium, it increases transparency, flow and gloss for traditional glazing techniques. Gloss Medium is concentrated and increases the adhesion, flexibility and durability of the paint film. It is recommended over water alone (excessive use of water as a diluent decreases the strength of the acrylic film).

To thin acrylic color, make a mixture of 50% water to medium and add to color until desired consistency is achieved.
