C Roberson Gloss Picture Varnish is a traditional picture varnish that gives oil paintings a high-gloss finish. It’s a nearly colourless liquid made from ketone resin, standoil & white spirit which dries to a clear, non-yellowing, non-blooming high-gloss film. You’ll need to let your paintings dry out & cure completely before applying it, which usually takes at least six months. Since it’s both flammable & potentially harmful, be sure to take sensible precautions – keep the container closed & out of reach of children. This bottle contains 250ml of C Roberson Gloss Picture Varnish. UK shipping by road only. Not available for International or Northern Ireland delivery.
