There are three choices for outdoor exterior finishes from simple to super
durable. The two biggest enemies of outdoor wood items are moisture and
ultraviolet light. Moisture causes the wood to rot and sunlight bleaches out
the natural color. Both processes undoubtedly are already underway in your
tabletop but the sanding probably will reveal more of the original condition of
the wood.
Exterior oil is by far the simplest to apply. Just flow it on , let it soak in
and wipe off the excess. You can flow it on with a brush, rag or even an
inexpensive garden hand pump sprayer. Oil offers the least protection and must
be re-applied annually. It's available at hardware stores, home centers and
paint stores.
Exterior spar varnish offers more protection from moisture and UV damage but
requires about 8 coats for most brands and has to be re-coated every few years.
An epoxy sealer with an exterior varnish topcoat is the most durable and can
last for many years but the application is more difficult.
