Paint for OSB?

[Jason280]

My 24x32' shop build has interior walls and ceiling covered in OSB, and I would like to paint it all white...any suggestions on a good paint that won't require too many coats?

 

[mygarageone]

It will **** up paint like crazy so I would suggest a quality primer coat first .

 

[jlipsky14]

I would use Zinnser or kilz. Should do it in one or two coats, that's what I used on mine. Don't use anything water based as it may affect the glues is the wood and absorb into the wood raising the grain.

 

[Jason280]

I'll check on the Kilz, bet it takes at least 5 gallons...

 

[jlipsky14]

Just checked I used Zinsser high hide oil base primer/stain blocker/bond coat. It worked great for me use a thick nap roller. I bought a 5 gallon bucket for my 24x24 but didnt paint the ceiling and used less than half of it so you should be ok with 5 gallons.

 

[nadogail]

Kilz-2 has been, for me, a reliable option. Dunn Edwards and Zisner also make excellent products.

 

[James-W]

I will suggest the same thing I have suggested to others, sand down the seams with a belt sander and then apply two thin coats of drywall compound. The drywall compound will make the OSB smooth all over and it will not require as much paint. But you will still want to use a good quality primer and then a good quality paint.

17 years ago I installed OSB board on the walls of a store room here. Two heavy coats of Kilz exterior latex primer (with a thick-nap roller), followed by two coats of interior eggshell latex. Still looks good. YMMV.

I also recommend an alkyd or shellac based primer for the first coat. Then you can used 100% acrylic for subsequent coats. I would not start with a 5 gallon can. If you buy in gallons, you can return unopened cans. Around here you don't save all that much buying paint in fivers anyway. Pour a couple gallons into an empty 5 gallon bucket, insert your roller screen and get to work! Definately use the long nap roller and consider one wider than the normal 9 inches.
Also, don't use flat paint. Spend a couple more bucks and get eggshell or pearl or whatever your supplier calls it. Flat paint is too hard to keep clean.

Any oil primer take your pick. Then a coat of exterior acrylic like A100 or SuperPaint from sherwin or comparable. Yep Im a painter lol

I did killz oil based primer on mine. 5 gallons did two coats on my 24x30x8. First coat took 5 hours for two people. Second coat took a little over 2 hours.

I'll also recommend the Kilz Oil based primer. After I had that on, I rolled Kilz Pro-X 170 latex paint over it in my garage. The house garage got, I think Glidden rolled over it.

Since the house garage is unheated, I used an exterior paint I believe. It covered nice over the primer but I would have to look at the can just to be sure what it was.

If you have the smooth side out and ink showing on the OSB, I'd suggest when you start rolling, put a coat over the ink first, then start the rest of the wall, effectively put three coats over the ink. Kilz is good stuff but sometimes that ink can be heavy and want to fight you.

I just did the same this last weekend, I painted 2 walls of my garage, essentially came out to 20 sheets of OSB that I painted. Used the Kilz 2 oil based primer, 2 coats and it took all of 5 gallons. The first coat really soaks into the OSB, 2nd coat covers everything up nicely.

Just went over the top of it last night with some higher quality Sherwin Williams interior paint and it looks really nice. Waiting for it to dry to see if I'll need a 2nd coat.

 

[Kennybill]

I also recommend Zinner oil primer stain blocker. That's what I did.

 

[Tucker99]

Spring for a 18" roller, frame, & tray. Saves tons of time and well worth the extra money. Wish I had this years ago, so much quicker to paint.

That's what I said earlier but think twice about it if you don't have strong arms and youthful endurance.

 

[Rex_A_Lott]

I recently did the same thing. I went to Home Depot and got the paint with the primer in it, guaranteed to cover in one coat. I think it was a Glidden paint. I had to put two coats of it on, but it looks good. I think that one-coat stuff is meant for sheetrock. I just rolled it on, nothing fancy. Good Luck!

My shop walls are all OSB. I went to the local Restore shop which is a Habitat for Humanity store. Businesses donate unused products - lots of oops paint. I took a bunch of light colored paint which was $2 a gallon and mixed them all up in a large bucket. Threw it up on the walls (2 coats, no primer) and it looks great. It's been a year and is holding up well.

 

[PeterT]

Me too.... By the way, that OSB ***** up the paint so a primer coat might be an idea. I think I might of hung some of my OSB smoothside out, so it really sucked it up when painting the inside.

I have the same problem. Jason ... will you need any help? Where are you located?

This is the thread about painting OSB ... right?

I'm planning on putting OSB on the inside of my 42x23.75x10 shop. I was thinking about painting the OSB before I put it up. I figured the 4x8 sheets would be easier to paint while lying on the shop floor than vertical and I wouldn't have to worry about drips on the Rust Bullet floor.

But it appears that everyone is applying the OSB first and then painting it. Is that the best way to go?

If you're not too far away Jason ... maybe I could come over and help you for a while to get some experience in doing this.

 

[NUTTSGT]

I'm out in the garage and looked at the glidden paint I used in the house garage. Its exterior satin paint

That's another great idea. Mix light colored paint together, even mix flat and semigloss, for the first one or two coats and then if you want white, just pay retail price for the final coat and still get the exact shade and sheen of white, pale gray, or whatever you want.
Unless you want to pay for extra light fixtures and extra electricity to run them, remember that dark walls, although dramatic, **** up thousands of lumens.

 

[Doozer75]

I did my OSB shop walls, bought 5 gal bucket of Kilz oil base primer (2 coats)
and used Rustoliem white. Looks fabulous. No latex paint for me.

Why no latex?

 

[jgschroeder99]

I used Zinsser oil based primer (1 coat) and Dutch Boy latex paint (2 coats). I think it came out really well. Some of the OSB grain and nailing lines will show through the primer. This is OK since the primer is just there to prep the surface for paint, not hide everything. I used a floor scraper and push broom to knock off any loose chips first. Then I caulked all of the corners.

[fastbike02]

I'm getting ready to hang osb in my shop what is the best way smooth on the inside or out ? and what do yall think about adding some drywall mud in the paint to give the walls a texture and hide the joints alittle bit? so for hijacking thread just figured it was better to ask that start a new one

 

[walrus]

I put 2 coats of oil based Killz and then 2 coats of Home Depot Latex on my walls. They look great and the walls can be cleaned of hands prints pretty easily

 

[dlcwent]

Although white paint does brighten things up, I really like the look of OSB as it is. Kind of a cheap wooden wall look.

 

[Jason280]

I don't mind the "look" either, but hoping that a nice coat of white will help with lighting.

 

[Shiftless]

Why no latex?

The water in latex or acrylic paint tends to raise the grain on bare wood. To avoid that, use oil based or alcohol based PRIMER as a first coat. After that, you can use water based paint.
Just don't paint latex paint over oil based paint that isn't a primer. It will peel.

I used only 2 coats of plain old Glidden interior latex house paint in a light grey.

I laid tarps along the base of the wall for mistakes and overspray then sprayed one coat left to right, when I got to the end, I went back and did another light coat up and down. I did it all (24x36x10) with about 7.5 to 8 (edited) gallons. Plus, it only took me about an hour to do it.

I will buy anyone a beverage of their choice that can find a thin spot, it turned out great.

[BruceMc]

That's pretty good - getting ~4000 sq ft of coverage (and sprayed, no less) out of less than 5 gallons and no primer.

 

[jlckmj]

Bruce,

Actually, I have to change that, I just saw a 5 gallon can today in the shop that is about half full yet, so I probably used 7.5 to 8 gallons of paint.

Hi there!

I put Zinser oil-based primer on my OSB ceiling, then 1 coat of Behr primer+paint in satin white. I used a thick nap roller. It worked great. I haven't painted the walls, since the weather turned cold right after I did the ceiling.

I used an 18" roller frame, which made painting go faster but it is definitely heavy.

I installed the OSB "smooth side out" but I don't think it matters much.

 

[Jon_E]

I am going to be putting OSB on my walls and painting them white, but also going to paint the ceiling, which is exposed roughsawn 2x10 joists with Advantech sheathing above. I like the 'industrial look'. I was thinking sprayer, but I don't own one. Any recommendations on a good spray unit or a better way to do this?

 

[Vette10R]

Back in the day I used to build subwoofer boxes out of MDF, that stuff would **** up paint like you wouldn't believe! I found a little trick that if I took some of the titebond 2 wood glue and mixed it with a little water to thin it out then paint the glue/water mixture over the entire box it would create a barrier that would never peel away from the wood then any paint I used would stick to that glue in one coat and never absorb into the wood. You could do a little test section and see if it works the same which I don't see why it wouldnt. I don't remember the exact mixture I would use but try at least 50/50 or even thinner...
