Liquitex Matte Varnish is a low viscosity, very fluid, 100% acrylic polymer varnish. It produces a matte finish that does not drastically reduce color depth as does Matte Medium. It's water soluble when wet and offers good chemical and water resistance when dry.
Dries to a non-tacky, hard, archival, flexible surface that is resistant to retention of dirt and resists discoloring (non-yellowing, non-fogging) due to humidity, heat and ultraviolet light. Depending upon substrate it allows moisture to pass through (breathable). It will not crack as surface expands and contracts during temperature and humidity changes.
Applicable for any acrylic painted surface (flexible and rigid) on canvas, paper, wood, stone, Plexiglas, etc. Not for use over oil paint.
