When your bench is completely dry, coat it with an exterior penetrating oil finish. There are numerous commercial products available from brands like Cabot, Penofin and Sikkens, and they run from the $35 per gallon range and up. If you can find a product in quarts, one quart will give you three rounds of refinishing. These products also come in various tints. Your bench was originally finished in Cabot Woodtone Deck and Siding Finish, with the tint labeled “natural”. We suggest that you talk to a local paint retailer about your options, then follow the manufacturer’s recommendations for applying their product to your bench.
With regular maintenance your Leopold bench from Pleasant Lake Hardwoods should give you many years of comfortable outdoor seating.
