Most people think that it looks ugly.
Painting will involve re-painting, every .. ? .. years.
Depending on the size of the shed - board & batten
might satisfy most people's esthetics. It's what I did
for a few small garden sheds, over the years
at different homes. My neighbour just replaced a
large tin garden shed < ~ 14 ft. x 10 > that was on
a nice concrete slab with a board & batten shed that
stands a few feet taller and it looks & functions great.
Be sure to paint the edges, that is the most vulnerable area. See below.
OSB's other moisture challenge has to do with dimensional stability - in
other words, OSB can irreversibly swell, especially at the edges, when
it gets too wet. This is not a decay issue, but swelling can cause other
difficulties in construction. ... In addition, OSB is bonded with
OSB is prone to moisture absorption and swelling. You'd have to paint all 6 sides with oil-based paint to help keep that from happening. I would not do it, unless you want to patch in perpetuity. As an alternative, I just built a shed (9x16) last year and used 19/32" thick T1-11 siding. I chose the thicker panel because the thinner one (11/32") felt like I'd punch through if I accidentally hit it while parking the lawnmower or something. I painted two (2) coats of white oil based primer ("Zinsser Cover Stain 1 gal. White Oil-Based Interior/Exterior Primer and Sealer" from Home Depot or Lowes) on outside and 4 edges, and 1 coat on inside. Oh, and the whole thing is min 9" off the ground, built on concrete sonotubes, to keep the splashback from the ground/soil from rotting out the bottom of the facade or structure. And, I included Z-channel metal flashing on the panels at gable ends, also to help protect against water entering an edge. Looks beautiful after one northeast winter, and is built like a tank. My method is definitely not as cheap as using OSB, but I'll be living here for quite some time and wanted it done once and right, without regrets.
