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.
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 the final topcoat varnish. It can be used, however, as a preliminary varnish as soon as the oil paint is touch dry, making it useful for varnishing before an exhibition. Retouching Varnish can be removed with Turpentine or White Spirit prior to final varnishing. Contains White Spirit.
