Sometimes the same can be said for boards. When one side is moistened (paint/stain) and allowed to dry the result will be warped panels. You may be able to get it all laid flat and nailed down but it may make for added difficulty. Differential drying is what happens to sometimes make the plywood sheets come pre warped from the store/yard. I should install first then paint MountainDon?

Quote from: MountainDon on November 09, 2010, 09:14:17 PMYes, install first.How far above ground is the bottom of the sheet? Protect it against ground splash. Gutters help.
Quotecap the bottom edge.
Quote from: Don_P on November 10, 2010, 08:51:10 PMI agree with that. I have pretty much the same opinion regarding paint in many applications. Finishes that form a film work great as long as the film is intact. when the film cracks or if water gets in behind the film it is a composting bag. a drop of water that gets behind a film is converted to several cubic feet of vapor that is trying to leave once it warms up. If it can't get out the moisture content of the siding rises. I prefer finishes like stains that repel liquid water but allow water vapor to get back out. I've got 25 year old T1-11 on a shed here that has been motor oiled twice I think (not that I'm suggesting that), still in good shape. I had always planned to just use that as a temporary sheathing and cover it with another siding later.
Quote from: dug on November 10, 2010, 09:27:07 PMThere are a lot of choices but I'm not sure what the best would be. I used a solid color stain on my T1-11 sheathed tool shed and it is holding up well after 3+ years. It goes on like paint but as Don stated doesn't form a top film. Like I said, lot's of options and some are probably better than others but I second the motion for stain over paint on the T1-11. The rough surface soaks up a lot so I diluted mine a bit, seemed to work well.
