M. Graham Artists' Acrylic Medium Gloss Medium & Varnish 4oz
Gloss Medium is a crystal clear, water-soluble, permanent final coating for acrylic paintings that will not crack or yellow. 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.
Note: To thin acrylic color, make a mixture of 50% water to medium and add to color until desired consistency is achieved.
It is recommended by M. Graham over water alone (excessive use of water as a diluent decreases the strength of the acrylic film).
