What is varnish and do I need to use it as well as a topcoat?
Varnish is water based clear coat that is sprayed in a light mist over the water base paint. Its purpose is to form a protective barrier between the paint and the topcoat, thus allowing easier topcoat application. Varnish is not a topcoat. Lightly mist it on just prior to topcoat application. After applying Wet Glaze you may use an optional coat of heat cured or UV cured nail topcoat if you wish or apply a second coat of Wet Glaze. Additional coats will extend wear.
