Have one just no time. I am putting all new 1 1/2 stainless hand rails and just started redoing all my decks today. I am removing the old teak and installing new plywood then 032 aluminum and after I have it all sealed I may install new teak or what ever I come up with.
Why plywood, aluminum & then wood decking? Plywood to enclose it, then aluminum to keep it watertight & protected until you decide on the wood decking?
