Our teak face plywood is made by applying teak veneer to an exterior type plywood substrate, usually meranti. Typical boat applications for the standard grade panel includes cabinets and interiors. It has also been used with some success for exterior applications, however No Warranty is available for exterior application.   The plywood must be fully sealed on all sides and edges with a proper marine or exterior varnish for any type of marine use.  For exterior use, additional coats per the below *finishing instructions or similar must be applied.

This product is produced with Type I exterior glue and is NOT an actual marine grade plywood.  It is intended for interior cabin use on boats.  It is not guaranteed for any type of exterior use. Even if heavily coated in marine finishes, it could fail.  If you intend to use this on an exterior exposure application you must completely seal all edges and faces to keep water from penetrating into the plywood. 4 coats of Smith’s clear penetrating epoxy (or equivalent) must be applied to all edges and 2 coats to both faces. A minimum of 10 coats of exterior varnish (Spar varnish or equivalent) must be applied to all edges with at least 6 coats applied to the good face and 2 coats on the back. No warranty is available and never use below the water line.
