If you get OSB wet it acts like a sponge, then starts to flake and gets soft. When used in sheeting, if you look at the sheet you will notice that one side has usually blue and red lines on it, these are to help when nailing the sheet down so that you don’t need to strike lines to hit rafters (or joists, ugg, if you decide to use it as subfloor)

Thanks, Jeff. Good point about one side giving more traction on the roof.
I'm just going to be using it as the sides and floor of a workbench. It will be ugly but it will be cheap and likely warp less than plywood.

As for it's structural capabilities either side can face up or out. When I sheath a new roof I prefer to have the rough side up as it is less slippery and provides some traction. hope this helps jeff

Is there a difference or purpose for either side of OSB sheets? I notice that one side is always smooth and the other side is rough. I've sort of assumed that there was an additional adhesive added to one side. However a store associate says that the smooth side is the side that was cut.
Thoughts?
