Bristol Finish Traditional Amber urethane is a high-performance urethane varnish for interior and exterior wood applications. The urethane varnish provides the highest UV resistance possible for a transparent coating. Suitable for fine furniture, yet tough enough for high-traffic floors, the varnish is a low-maintenance alternative to spar varnish. Spray, roll, or brush-on applications dry quickly so you can re-coat multiple times in one day. No sanding required between coats.
