Paint OSB

[bookman51]

Is there anything recommended to cover OSB that would smooth out the bumps? With the warmer weather I plan to start painting the inside of my shop.

grain filler?

Skim coat it with drywall mud. Fast, cheap, easy.

I just paint it with good paint. If you want smooth walls you should have put up sheetrock.

I did put drywall in most areas. I put up a few sheets of OSB where the wall might get bumped occasionally. Just trying to make the wall look similar.

Your best bet is the drywall mud then. It is a bit of a PITA to get it to look just as smooth as drywall tho.

Yup, my Dad did this a few years ago in his shop.

It's not horribly hard. I had to do quite a bit of skim coating in my current house. Buy a bag of the fast-set drywall mud. I like the 90 minute stuff. Lay it all on with a fairly wide putty knife. Then when it's dried, first scrape off any high spots/runs with the same putty knife then use a palm sander with a dust collection system attached to a wet/dry vac. One more coat and quick sand should do it.

Although I'm confused, if the OP wanted to use OSB to make the wall a bit more durable than drywall, putting drywall mud on it will make it just as susceptible to bumps and scratches as drywall but with the extra effort. I don't think there's anything you can just spray or roll on that will give you a flat surface otherwise skim coating would be about 1/8 as hard.

Thanks for the help. It might get scratched, which easy enough to fix, but probably no holes in it.
