Painting OSB

[CEthridge]

Getting ready to paint/finish the walls and ceilings in our OSB 3 car garage. I really appreciate all the paint recommendations, but I would like to see more about what you all did with joints and screws. Who caulked? Who taped? Who did something else?

I used OSB with three quickly rolled on coats of Mr. Seconds latex wall paint. No primer, just roll on the paint. The paint was dirt cheap, in a 5 gallon bucket, and looks great after 10 years.

Ha! I used to shop there when I lived in WNY! In fact I worked across the street from the one on Genesee St. (Grossman's Lumber)

Anyhow, I have also had luck with using a cheap brand of (slightly thinned) oil based primer and a latex topcoat... I have also hung it with the smooth (dimpled) side showing for a more uniform look.

Hi got a question, my old garage is fall apart with the walling its got some kind of old sheathing on there not OSB! However I wanted to use OSB and was wondering if you could pain it. I been reading this forum telling me I can and I am looking up these paints / primers to use! but I can't find Kilz Oil Based Primer for Exterior use! only Interior use! and lowes has this Kilz Interior/Exterior Latex Primer I dont know if I could use that then paint it!

Also there are a lot of new paints out there with Primer and Paint! Wouldnt be more simple to go with that and cheaper? Or should I stick with Oil Priming it and then painting?

Any information you could give me would be a great help.

Thank You.

I'm just finishing up mine. My experience is that there are no real shortcuts. It took 3 coats to get the coverage and finish I wanted. Didn't seem to matter if it was 2 coats of primer and 1 coat of paint or the other way around. Don't try to cheap out on the amount product, it takes a LOT of product to get good coverage and finish. I used both latex and oil based primers at different times and the oil was slightly better.
If you have the means to do it, I would suggest getting at least one coat of primer on before putting it up. I found that by getting a coat on it on the saw horses before putting it up made the product flow into the nooks better and made the final finish smoother. I know others have had different experiences, but this was mine.

I recommend Kilz oil based printer with a 3/4" nap roller and load it on well. After that 2 coats of finish paint. An exterior semi gloss latex enamel seems to work well. That too needs a 3/4" nap roller. Don't skimp on the paint. Load it on.

I put one coat of oil based and a couple of coats of water based. Once I got it painted I see a lot of this, you can see it looks like an old bolt.

Hey, new kid on the block here, just joined, wanting info about painting or covering OSB - this forum has a lot of really good info and ideas! My workshop is 10 x 20, all walls + ceiling done in OSB. I will go for the Kilz + primer + paint. I appreciate having a place to go to get good info from those who have experience. I need all the light I can get in this workshop so I will go with semi-gloss, it's a good compromise.

P.S. I'm a girl too.

;o)

I used one coat of oil based kilz and two coats of exterior brick paint.

The kilz is a must, also a large nap roller.

[BI was curious as to use luan plywood on exterior walls. I can't afford the good stuff, but i know that luan is very strong, but it can also warp and split. Is there anyone who used this plywood for exterior use like on my storage shed. I know you must seal both sides with oil base primer, and i know i would use oil base exterior paint. I love oil based stains and paint.[/B]
