Winsor & Newton Oil Varnishes
Winsor & Newton Oil Varnishes are final coatings which protect finished pictures from the 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 so that paintings can be cleaned in the future. Oil Varnishes are labelled ‘gloss' or ‘matt', it should be noted that different resins used in the varnishes impart varying degrees of gloss.
