This versatile varnish is used to bring back the original paint quality of dry or dull oil. Retouching Varnish is reduced with solvents and is much thinner than final top coat varnishes. By its very nature, oil colour is incompatible with water and dissolves only in turpentine, white spirit or low-odour thinners. Artists' oil colours are made by dispersing pigments in an oil medium to create a smooth, slow-drying paint. The choice of oil mediums from the wide variety available depends on the surface and the finish required, and the working properties preferred during painting.
