Pebeo Retouching Varnish for Oil Colours is a very fine and discreet varnish composed of acrylic resin. It is used in smaller areas, during painting, to correct coats which sometimes accidentally produce an unwanted matt sheen. It unifies the brilliance and corrects the problem. It is always used in fine coats and gives temporary protection. The varnish will protect the work and give a uniform finish. The thermoplastic film allows the possibility for the eventual restoration of artworks.
