SYSTEMTHREE Polyurethanes, Shellac & Varnish 1855S24 Editorial Review

The System Three Marine Spar Varnish is a quality product that provides UV and water resistance. However, it is recommended to use a 2-step epoxy sealer before applying this varnish on exterior wood to prevent moisture intrusion. The varnish is not suitable for raised panel doors with natural thermal/moisture movement. It is suggested to use a penetrating oil finish for front doors. The product is easy to apply and provides a self-leveling finish. It is expensive but provides a brilliant and tough finish.
