In the end mother nature will get all your outdoor furniture. Your options are to regularly do the work to maintain the furniture or learn to live with that grey, weathered look. I don’t like the weathered look, I like my outdoor furniture to look as new as possible. One easy thing to do is to stop moisture from getting into the legs. Those legs normally have their end grain in direct contact with the ground. That causes rot, decay, and eventual failure. This simple method requires nothing more than epoxy and masking tape. West System Epoxy is expensive, but the 1 gallon one with pumps will last you for many years.
