I'd like to build a small (6'x8') floating deck for my yard. The deck would be resting on gravel. Ideally I'd like to use pressure treated wood, but a few of the pieces will need cuts, and my local store will only cut untreated wood. So I plan to use untreated wood for the deck.
What can I do to protect untreated wood from rotting, etc. Can it be stained? What product should I use?
