Global Colours Polyurethane Gloss Varnish is a concentrated glazing medium for artists, which produces a final clear protective coating of the toughest degree. It is a hard polymer producing a non-tacky concentrated glaze, designed for maximum gloss on hard surfaces where flexibility is not needed; e.g. concrete, wood, or boards. If greater flexibility is needed use Global Colours Gloss Medium and if further flexibility is needed then use Binder Medium diluted with water.
For varnishing, use this product undiluted. Evenly apply slowly with a soft, broad brush in the direction of the wood grain. Allow to dry for several hours between coats, 2 to 4 hours is recommended, as coating before the previous coat has dried can cause the varnish to dry cloudy. Do not apply more than 3 coats in one day. Dry time will also vary depending upon weather conditions and temperature. Can be sanded gently after drying for 24 hours.
Apply 3 coats for water and alcohol resistance. Do not use over oil-based products. Suitable for indoor and outdoor application.
