UNDERGLASS

UNDERGLASS

This varnish is particularly recommended for preparation works on wood and marine plywood, both on interior and exterior of boats. For its outstanding sealing power provides excellent waterproofing characteristics and resistance to humidity conditions. Recommended as a basecoat it can be overcoated by two-component clear varnishes or polyurethane enamels but also with further coats of topcoat varnish or with synthetic undercoats. For best adhesion sandpapering between coats is recommended.
