Gamvar Varnish saturates colors in your painting and gives your work a unified and protective surface. Developed in collaboration with the National Gallery of Art, Gamvar can be easily and safely removed with Gamsol. Gamvar is virtually odorless and ready to apply. Brush apply using the Gamvar Varnish Brush. Do not spray. All Gamvar can be applied when the thickest areas of your painting are thoroughly dry and firm. Gamvar Satin saturates colors in your painting, yet dries to a lower gloss level compared to original Gamvar.
