The sub floor is down but now I am concerned about keeping it fresh and preventing the sun and potential rain from "fuzzing" it up. So we decided instead of covering it with $50 worth of plastic and trying to keep it from ripping we would paint it with the same amount of money. We choose a gray latex floor and deck enamel. I rolled 4 gallons of paint on it in about 3 hours, that is moving pretty fast. It didn't cover that well but it sure sealed the surface and that was the goal.
