Paint should be reapplied only as needed. Also note, unfinished wood like teak will adopt a gray sheen over time. Do not worry; this process does not directly harm the wood in any way. Rather, it is the sun’s natural patina process fading the wood into an aged, mature look. If that’s not your thing, make sure you keep up on the varnishing.

However, just as you do, the rain starts to pour down like crazy as you try to set up your hammock in your backyard.
