Formulated as a low molecular weight synthetic resin varnish, GamVar has a refractive index similar to dammar natural resin varnish. Gamblin's GamVar was created in collaboration with Rene de la Rie at the National Gallery of Art in Washington to bring the studio painter a contemporary varnish with their most stable resin identified. 

GamVar gives your Oil and Acrylic paintings a protective and unified surface, available in three surface qualities sure to suit whatever look your painting needs. Pre-mixed, virtually odorless and ready to apply. 

All Gamblin Mediums will be temporarily unavailable as they have been recalled by Heath Canada due to labeling issues. Thank you for your patience as we await an ETA.
