Finishing OSB walls?

[Frank]

Just can't get a search to work for "OSB" so forgive me if its been covered.

So I had my new garage lined with OSB rather than sheetrock. Now I would like to texture/paint it. The "slick" side is facing in. I heard that it takes a different kind of primer than used on sheetrock? Can I finish the seams with tape and mud like sheetrock or how should I handle that?

I've seen threads on here where guys taped the seams and added some spackling compound to their primer then rolled it on!

tape em, then shoot it with a hopper gun, to what ever texture you like.
I did a garage wall in other house with low knock down , look good!

Oil base primer seems to be the way to go. Caulk works for the seams and is way faster than tape & bed. I'd be afraind the water in the bedding compound would fray the OSB surface.

I did my shop walls about 9-10 years ago with 7/16 OSB. I just butted the edges together tight and nailed it down. Seams don't show that badly. I recall sanding a few that stuck up a bit and I may have caulked a few wide gaps. Overall though, everything laid together pretty tight.
For painting, I used an oil based primer/sealer, did two coats of that and then 2 coats of oil based semi gloss white paint.
A friend of mine had a Wagner power roller which we used. That worked great as the OSB really sucked up the paint! I want to say 4-5 gallons of primer and 4-5 gallons of paint for approximately 175lf of wall about 8 feet high.
Overall, I'm very happy with how it looks and works in my shop.
I did scrape up one photo to share.

so should the smooth side go in?

I just did mine with the smooth side out

If you do drywall type texture, prime once first sandwiching the compound between 2 primer coats.

I just finished mine. I have smooth side out and then over the joints I cut 1 1/4'' strip of thin plywood and air nailed them over the joints and then painted.Looks great.

If I had any gaps, I caulked them. I rolled on oil based Kilz primer. I think spending a little bit more on a good oil based primer for OSB is worth it.

Have you had any issues with flaking, peeling? Were you painting on the shiny side?
