M. Graham Acrylic Gloss Medium
Gloss Medium is a crystal clear, water-soluble, permanent coating for acrylic paintings that will not crack or yellow.
Gloss Medium is recommended over water alone as excessive use of water as a diluent decreases the strength of the acrylic film. Gloss Medium increases the adhesion, flexibility, and durability of the paint film as well as enhances the color.
To dilute acrylic color, make a mixture of 50% water to medium and add to color until desired consistency is achieved. Used as a medium, it increases transparency, flow, and gloss for traditional glazing techniques.
