OSB for interior walls - prime/paint before hanging? etc

[liljestrom]

I have a garage with romex and outlet boxes that is 32x36 and will put OSB on the walls. I'll have to cut out for the boxes and a couple of windows. Previously I have done this and primed and painted after it was up.

I'm thinking hang it all then prime/paint.

Does if make any sense to prime/paint the sheets then cut out OR prehang/take down and prime/paint?

It's easy enough to roll paint onto walls. What do you gain by painting before hanging it other than the fastener heads being unpainted?

I would think that managing multiple sheets while painting one side would be a nuisance as well as an opportunity for the OSB to warp and make hanging it more difficult as well.

Paint in place. It's one thing to prepaint detail stuff like trim, but I wouldn't do wall cladding like that.

Renting a sprayer would cut the time massively, just cover absolutely everything else in plastic.

We used to have one of these style paint rollers where the handle is a giant syringe full of paint.

Worked great.

I have a roller attachment for my sprayer... Curious how well it works but I don't really want to find out

rolling/spraying it after it's up will be easier than any other approach

Not really what you asked....but I'm going to give you my thoughts anyway.

Strongly consider spending the extra money and getting tongue/groove plywood, instead of OSB. Yea, it's 10-15 more per sheet, but it looks SO much better after you install and paint it. And for damn sure is more solid for heavy cabinet/other things mounted on the walls.

I even used caulk to fill the joints on my vertically installed sheets, which makes the walls look almost seamless.
