Exterior Polymerized Tung Oil Sealer

The blend of UV protection, fungicide, and polymerized tung oil makes this a high-performance exterior coating suited for a wide range of outdoor applications.

Thanks to the natural elasticity of polymerized tung oil, this finish is able to flex with the wood through harsh seasonal changes. With proper, timely maintenance, it provides lasting protection against the elements.

Sutherland Welles Ltd.® Exterior Polymerized Tung Oil Sealer is formulated to penetrate deeply into the wood fibers, creating a strong, protective foundation. It is recommended as a primer coat prior to finishing with Exterior Polymerized Tung Oil Medium Luster or Marine Spar Varnish.
