Studio Project: Plywood (as a wall finish)

My design studio acts a lab for experimentation, in this video I discuss lessons learned from installing plywood as a finished wall surface. The four main discussion points covered are:

1) Material thickness: 1/2" - 3/4" typical range. NOTE: if you're using sprayed foam insulation in your walls, the plywood covering must act as an ignition barrier for the foam - thickness will be critical. Thickness also affects: translation of framing inconsistencies to the finished surface, stability and price.

2) Panel cores and veneer faces. Steer clear of the Chinese Plywoods. Choose panels from the same lot and age if possible. Veneer plywood has a front and back side; the less banded side is the finished face. Take care when cutting to avoid material blow-out.

3) Attachment. Concealed versus exposed fastener. I recommend a concealed clip as well as a tip for aligning the finished face of the panels (it's a special fastener).

4) Finishing. Determine the project goals first, then select the finish. Mine were: - Low sheen - Preserve natural wood appearance - Easy to apply - Non-yellowing

I review oil-based and water-based finishes, Danish oil, spar varnish, paste wax, natural soap (Hans Wenger furniture), and finally WOCA oil + lye.
