Solving a Century Old Problem for Oil Colorists... Someplace in Portland-Gamblin Artist colors has solved a centuries old problem for oil colorists wanting to protect their artwork. It used to take up to 6-12 months. This made it hard to sell artwork that was properly varnished. Varnish is the first defense of artwork and when not used will expose the painting to direct and chemical pollution.
Gamvar uses a synthetic and elastic replacement to damar which is inelastic. Thus when the painting dries the varnish moves with the paint film so there is no problem with cracking.
