The combination of UV guards, fungicide and Polymerized Tung Oil make this a superior exterior coating for a variety of outdoor applications.
The elasticity of the Polymerized Tung Oil allows this finish to withstand harsh seasonal cycles. This finish requires timely maintenance to protect the wood.
Sutherland Welles Ltd.® Exterior Polymerized Tung Oil Sealer is formulated for the tung oil to penetrate deep into the wood. We recommended it as the primer coat for finishing with our Exterior Polymerized Tung Oil Medium Luster and Marine Spar Varnish.
For best results, use within one year of manufacture date on the bottom of the can. Once finish turns milky, it is no longer usable.
Exterior Polymerized Tung Oil Sealer
Sutherland Welles Ltd.® Exterior Polymerized Tung Oil finish requires timely maintenance to protect the wood. With multiple seasonal cycles the finish will eventually develop hairline fractures that allow moisture to invade, but with timely maintenance coats those fractures are filled in with new Tung Oil and help keep the finish intact. Ultraviolet light from the sun is the biggest threat as it completely weakens the finish. So how often to re-apply the Exterior Tung Oil will be a function of how much sun it gets, but at a minimum we recommend an annual application. Timely maintenance reduces the labor involved to keep a project looking great and well protected. Reapplication is easy, just clean and re-coat.
