Moisture exposure is a leading cause of deck deterioration, whether from precipitation, waves or water splash from pools and hot tubs. The volume of moisture exposure can be huge. If you build a modest-size commercial deck in a city on the Gulf Coast, every year it will be exposed to more than 200,000 gallons of rain thats nearly six full rail cars of water pouring on the deck annually.
