I did a wall in my garage years ago and it's indistinguishable from drywall. Would have been cheaper to use drywall, but I had the OSB and other materials already. I first primed it with Killz oil based primer (this will prevent moisture from reacting with mud. I believe I used the +3 mud and I put heat lamps up while it was drying, this prevents the mud from shrinking as much. I did two very thin coats and then skim coated the whole thing. Used a drywall knife to knock down the high spots and liftoffs when it dried, a light sanding. Then primered with a water based primer, another quick sanding and painted. You can't tell it's OSB and I like it better because I put French cleats across the wall and don't have to worry about wall studs.

This video came out at just the right time for me. I took an osb ceiling out of the garage and I'm turning it into some sturdy storage boxes.

That’s awesome ! Great way to repurpose old material!

I like the idea of using OSB for finish products like shelves. One expansion on your method is to prime the OSB first. In construction we used OSB mostly for interior garage or basement work but found priming it prevents the strands from swelling and keeps excessive water from dissolving the material altogether. Spackle and drywall mud work great on filling imperfections like OSB spaces as well as resurfacing old house trim that has paint runs or gouges.

I’ll get some and try it next time. I might be doing this more often.

Do you use oil base primer?

That being said about using primer first, I have a small porch on my house that has painted OSB. I want to change the color and was wondering if mud would work over existing paint? I assume I would have to either sand or prime first to remove the gloss?

I did my whole 24x24 garage this way. Fast and cheap. I used a wet sponge to wipe it smooth. No sanding or dust. After 3 or 4 panels youll get it figured out and you can fly through the process.

I’m going to tape off and mud the inside of my shed walls that are OSB before I paint it, I saw a drywall finisher do this to wood paneling and it look good so I’m going to try it

@jimbobkitty 4 ай бұрын

now i want to experiment. i bet a light sanding of the osb before the mud would make a better result, i.e. like the edges that got smoothed by the saw blade. maybe even a quick but heavy sanding with a belt sander

I bought 440 sheets of Formica for 400 bucks several years ago. And since I still have about 400 left... I know what I would have done.

I'm using OSB for new soffit material to finish a 2'w x 72'l roof' extension. I've done exactly the same thing, only I used the other side of the OSB. The surface is flatter, with out any ridges. Other than that we've both used OSB in a unique way to save on expenses. Cheers!

I would probably trying sanding it first, then mud, Primer, Paint. Definitely has potential.

Thanks for showing us your experiment, I hope you would show us if it didn't work cos that's just as important! Interesting to know about drywall mud as we are using plywood to line our house but having trouble smoothing the gaps... Not sure if it would be too brittle and crack with the natural movement of the wood though.

@BOCraftsman Жыл бұрын

I think it probably would crack from moister and movement. If your also wrapping your house with Tyvek , it should smooth out the seems naturally .

I would have added some PVA glue in the mud because only mud might flake off more easily I reckon. Also first I would have sprayed the OSB with water to raise the grain and sand it right after, to avoid the actual mud raising the grain.

Where I live a sheet of Birch 18mm (3/4”), is about $200. Consider the average income in my country is about 1/3 of Western Europe and US, I treat every scrap like it’s gold and only use it for absolute necessities.

@anthonys1573 9 ай бұрын

This is a great technique which I use often for creating access panels. But you need to do as @stephensano9156 says and prime the osb first or you are going to see warpage on anything over about a square foot in size from the osb (or plywood which is surprisingly more susceptible to this) absorbing the moisture out of the mud.

As one commenter stated pva binding glue or some type non-water-based sealer like primer should be used prior to mud. Videos are like seeing food on tv and the host telling you how good it smells.
