I have built a yurt platform, which is basically a deck with 1 1/8" tongue-and-groove plywood as the decking. Usually that stuff is used as a subfloor, but in this case it's the floor itself. Call it rustic.
I bought this deck (and yurt!) standing at another location, disassembled, moved it to my location, and rebuilt it. The previous owners had painted the floor after assembling the yurt, so the paint doesn't go all the way to the edges. There are some rough spots from damage over the years. And some of the panels suffered in the weather while they were in storage. (I'm a slow builder!)
I would like to repaint it before I erect the yurt. I was thinking of renting a floor sander (the spinning kind) and taking a pass over the floor, and then putting on a few fresh coats of paint.
Most of the online information about painting floors is either for fancy indoor floors, or for outdoor floors exposed to weather. This will be protected from the weather once the yurt goes up, and our expectations are simple.
How should I attack this problem?
(Speed is an issue, we want this done fast!)
