I am thinking about using the 7/16 OSB on my detached garage walls. I don't want to use drywall because I don't think it will stand up to the abuse and other options are much more expensive. I fiqure till I get shelving and cabinets ect up you will not see much of the wall anyway. I figure if I hang things I will be hitting studs anyway so it will not have to hold much weight. Has anyone used OSB and if so did you paint it? I was wonding what it might look like varnished if you put the unmarked side out. Any thoughts?
