Painting OSB

[Stefan S]

Me too! The other thought I had was to purchase a small enclosed trailer and then sell it in a few months. I doubt I would lose much money if at all buying used.

I purchased some Wooster 1/2" thick nap rollers (made in the USA) and Kilz oil primer for my walls. a standard 2 car garage probably needs 3 gallons but I will see how it goes first.

I seriously doubt that 3 gallons is going to cover walls and ceiling of a 20x22. OSB soaks up the paint like crazy. My only slightly larger garage took around 7.5 gallons.

Also keep in mind that kilz oil based will yellow over time if not sealed with a top coat.

Just the walls. I am doing a white vinyl covered insulation on the ceiling. I will take the top coat into consideration and hope to use up some white I have on hand. Thanks.

Have fun!

I would dry wall right over the OSB for a fire retardent interior.

I put 2 coats of the cheapest 5 gal latex white home depot had. It covered fine using a deep knap roller. I did do mine outside before hanging it. Did the ceilings and walls. It's good enough for a garage.

So, is that a total of 4 coats?

Whether its oil-based Kilz or 4 coats latex... seems like more spent on paint to take advantage of the OSB cost savings over plywood.

I find I'm able to use up some of my older and odd-color (free) latex as I paint out my shop.

 

[Wileel]

Ripped all of mine out and put in sheetrock, but I care about how the shop looks and I wanted to insulate. Painted OSB looks like...well....painted OSB unless you skim it in mud and then you may as well put rock up.

I'd paint it in a heartbeat. Good primer will make all the difference.

No way would I put sheetrock in a garage. It would be full of dings and dents in no time. The only garages around here that get sheetrocked are strictly for parking. No work gets done in there and they still look bad in 15 or 20 years just from leaning stuff against the wall. I don't understand why it's so popular on here.

I've thought about this too as I had planned to do my 30x40x12 pole barn walls in OSB. Right now 7/16" OSB is under $10 per sheet and 15/32 plywood is $17.75 - at 52 sheets a difference of about $400...I'm considering it but some reviews say the plywood delaminates. Am I overlooking a better cost-effective option in plywood?

That's all I see at HD, $15 per sheet here. I would still be spending money to paint the ply. The latex primer is not really any cheaper than the oil based Kilz.

You must hit your walls a hell of a lot more than I do. I try to avoid them and have stuff against most of them anyway

My take - there's 2 types of people on GJ. One makes a spiffy man cave to park the hot rod or Porsche or whatever, and the other is using it as a work space. Different finishes appeal to different use cases.

I built mine with OSB on the bottom 8' so i could use the shop.

I've done 3 frame off restorations in my garage. Its a working garage. Built sauna stoves, all sorts of projects. There are no dents in dings in walls. WTF If you know how to use tools **** don't go airborne
I think painted OSB looks hideous.

Probably depends on your experiences and climate.

I **** it up and pay $25/sheet for 1/2" exterior-grade fir ply. It's worth it to me.

Yea, I've noticed it to. Still cannot comprehend the reasoning. I have never seen, in person, a shop of any kind with sheetrock on the walls. It just isn't done around here. Garages in nice houses, yes. Nobody is doing work in them though, parking cars only.

Plywood is nicer looking than OBS. Either one looks perfectly fine in my opinion. Paint makes the uneven surface of OSB more noticable.

My current garage is a pretty old building. The inside is completely lined with tongue and groove 1x's. If money was no object I would do that on a new build.

 

[like2wheel]

I was at my mil's recently & noticed the texture on the walls of her new house. I think its called "knock down"?
Was thinking a little of that on OSB might look good.

I’m with you on this
I did put up some 3/4” Birch plywood in a utility/power/boiler/compressor room the rest is drywall. The Birch plywood was price the same as 3/4” spruce sheeting so it was a no brainer as far as I was concerned.

 

[PugetDude]

MY current garage (and the last six) have all been drywall. I've managed woodworking, welding, grinding, painting, mechanical, automotive and fabricating projects in all of them without destroying the walls or burning the place down.

 

[Mikemac1]

22x24, OSB walls. Caulked the joints and put on two gallons of kills. It was white enough that I didn’t bother painting it. That was 6 years ago and nothing bad has happened. Well except for the mudjacking sinking back to where it was and that money down the drain.

I'm all for painting it. My last shop was OSB and my current one is plywood. I primed and painted them both semi gloss white.

A good way to save a bunch is use mistint primer and basecoat. Maybe get them re-tinted more the shade you want. Or just top coat in your desired color.

How many coats of oil based primer do I need on the OSB before I can start using latex on top of it? It will just be white on white but the latex is cheaper.

 

[kbs2244]

My guys just sprayed 2 coats of cheap latex on my OSB
No primer
You can tell it is OSB but it looks and works fine

 

[chaosracing]

We did just one good coat with Kilz. Two coats of latex.

Thanks, guys.

I did a 2 car garage where the ceiling was OSB. I painted it with Kilz. Bought a sprayer and a 2ft extension so i could spray from the floor. It soaks up the Kilz. For that much space, doing 2 coats spraying you will need probably 10 gallons or more. Rolling would use less.

 

[QwikKotaTx]

Nice job on that, walls and floor as well. I only painted a few sheets with 1 gallon of Kilz oil based. Had to buy 5 gallons more this weekend but haven't gotten to cracking it open yet. The roller lets you add more paint in the deeper voids of the OSB but takes a lot of elbow grease. I only have a few ceiling panels to do thank the Lord. I am caulking the seams and screw heads but not trying to make it as flat as drywall. Back is killing me.

 

[GRivera]

I caulked seams after but I was fairly **** about gap spacing and such

I also placed the rougher textUre out into the room. It’ll never be smooth like drywall so why even try. The texture looks intentional.

Is the smooth surface side paintable? I ask cause of the waxy feel...

The oil based Kilz adheres well to the smooth side but it's a real ***** getting paint in all of the nooks and crannies. I have used about 3 gallons on the walls alone in my 2 car garage. It's a bit yellowish so I added a top coat of white semi-gloss. Not very shiny when dry but it's done at least. In hindsight I would probably just pay a crew to do the insulation and do drywall instead. It was a lot of work.

I painted my ceiling on the floor with a roller. 2 coats of oil based kilz and 1-2 coats of white latex. Then hung the panels. It was a piece of cake and turned out really well. I am still going to finish with furring strips over the seams for a more finished look.
The only thing that I would do differently is use white screws so i didn't have to paint the screw heads.

 

[Hot shot]

I painted mine exactly the same way
Never thought of white screws either
I wouldn’t call mine a piece of cake
I had like 72 sheets to do
I like the furring strips idea

Did you lay plastic on floor and paint multiple sheets at once?

I did

 

[SkeeterZX200]

I painted the OSB in my shop. Overall, I am very happy with how it turned out. This is 1 coat of Behr interior paint.

 

[tom-ky]

I did one coat of oil based primer, Kilz or similar product with 2 coats of exterior latex. I put the smooth side out. One wall has been there 3 years and the rest didn’t get done until a little over a year ago. So far I am happy.

 

[GRivera]

Once the panels have a couple of coats of Kiltz, will a sprayer be effective for topcoat?

That looks great, did you prime at all and what's the actual type of behr you used? Also did you paint the smooth side or rough side

 

[Worsedog]

Wait...WHAT?!?!?

Sacrilege

All depends on perspective. For some, the project is the garage, for me, the projects are in the garage.

There's a place in NC that sells OSB with a flame retardant coating for $10 a sheet. I like the idea of the flame retardant, and I wonder if it finishes any better than regular OSB. Anyone ever seen the stuff? I'd go look at it if it weren't 90 miles from here.
