Winsor & Newton Dammar Oil Based Varnish 75ml
Varnishes are final coatings which protect finished pictures from build-up of dirt and grease. Oil paintings must be thoroughly dry (at least 6-12 months) before varnishing. For fine art usage picture varnishes should be removable sio that paintings can be cleaned in the future. Different resins in the varnished impart varying degrees of gloss.
