Painting OSB boards...

[derbydad276]

just go get some heavy primer and lay it down with two good coats and then lay your paint over top. we did that in my dads garage and turned out really good.

if i was to do it again though. i would buy/borrow a sprayer and spray it all instead of rolling. so much easier and faster if nothing is in your way

this rent a airless sprayer done quick

Use 1/2" or 5/8" CDX. My garage is 5/8" CDX and 5/8" Type X drywall. Wish I would have done the whole thing in CDX.

If you plan to condition the room (heat or AC) drywall is the way to go. Mud/tape will seal all air gaps....and there are a lot less of them to begin with. Air leaks are the worst thing for controlling temperature.

It's the ribbed 26 gauge paneling that they use for walls and roofs on barns

What kind of steel panels?

I used OSB for the inside of my barn. Yes, the first coat of primer seems to disappear as soon as you can put it on. I do 2 coats of primer and 1 coat of contractor semi gloss.
I lay the panels down in the yard and use 18" rollers and extension poles. It goes really quick that way. Then I cut them to size and put them up.
