Interior OSB Finish Ideas

Drywall is your best bet. Otherwise horizontal or vertical wood, wainscoting etc. going to take a lot of paint to cover OSB and have it not look like OSB. Alot of paint. Alot.

 

Yikes, drywall over it all? I've not dealt with this situation but drywall will prove costly. A texture splatter over a skim coat might be cheaper. The texture splatter afterwards would cover up imperfections in the quick skim coat.

 

Id hang plasterboard over it before i bothered to skim it.
Why not look into what you can do to make a feature of it stain and clear coat?

 

Found this idea, the osb was stained a dark color, then with a short nap roller painted white.

They said it celebrates the osb rather than hides it.

What do you think, may work for tall cathedral ceilings in this build

 

Yeah that looks pretty cool.

 

I'm my area this wouldn't pass code for flame spread reasons. If its living space you need to cover the osb with drywall.

 

So I Googled "Flame Spread Index" and found this doc from the American Wood Council:

www.awc.org/Publications/dca/dca1/DCA1.pdf

They say that "most tested wood products have a flame spread index less than 200, making them acceptable under current building codes for a wide range of interior finish uses."

so I think that it meets code from what I read.

 

drywall it. Seriously, do you want the inside of the house to look like a garage with painted OSB?

 

Cover that crap up man. You can put anything on there. You have infinite nailing locations

 

There Is an alternative ! If your willing to pay for it. This process can work over brick.Block.Wood...etc. The seams on that osb will need to be taped and one coated tho. [imo] http://www.frescoharmony.com/index.php/galleries

Don't quote me on this !! But I think this is around $2 a ft. So you do the math ...Fresco or Drywall it And finish it off smooth.

I know this tho...Drywall over that osb will make for some nice flat ceiling and walls.

 

Check out Nick's You tube channel ..He has a vid where he trowels over a ply board kitchen ceiling . Turns out nice! And he has a large variety of colors to choose from.. After the sealer goes on ...No painting..

No sanding either.. I'll say that again...No sanding involved !!! Plus you get to kick the painter to the curb!!:laughing:

 

the point of the thread was ideas to avoid drywall,
that what the client wants.

input along those lines are appreciated.

so far they like stain with white paint over for the ceilings.

Yes they will save money doing that way, if fact the roof panels can be stained & painted while on the ground super fast before hoisting up.

No scaffolding etc only thing to do is caulk the seams, but the 10 roof panels are 8' X 18', not that many seams.

 

Exposed osb . That's fancy.

But... It's not mine to ask why!:whistling

 

Have known SIP panel homeowners to cover with drywall mud then paint. They said it was durable and couldn't tell difference. I'm experimenting with some now

Anyone still here? I'd be curious to know how this has evolved...I've had not-great adhesion of mud over both primed and unprimed OSB, and then similarly-crappy adhesion of even "the best" primers I could find over the perfectly-flattened resulting surface. Nothing like starting THAT process all over again. Then, my point was to get to a nearly-defect-free starting point to apply lime plaster, but I won't live long enough to continue THAT process, sadly (being hyperbolic, I hope.)

I got here while googling for a roll-good of some kind (how about rosin paper?) that would created a drywall-like base for "decorative coatings." I'd install it over OSB like wallpaper, after doing a level-one-ish prefill of gross defects, then...well, not sure - could be a conventional solid color, or something faux-ish - whatever I could do on a level 4/5 gyp installation. My premise is to NOT use gyp, which I have grown to hate (for the swelling in our humidity, the ease of damage, the massive added weight, the mold...sorry if this offends career rockers here.)

Blacktop's link Fresco Harmony | Wall Treatment System still works. It's pretty interesting - I mean, I only spent about thirty seconds clicking around on it, since I've had way too much coffee already, but it looks like a poor-man's much-quicker version of traditional lime plaster: you mix colorant with topping mud from your local home center, trowel on with your choice of methods, apply sealer if you choose. I don't think you can get much of a burnished sheen effect with mud, like you do with marble-based plasters like Veneziano, but I'm all about experimentation (my will back me up: my projects take even longer than they otherwise would because of these excursions...)

If you're trying to avoid gypsum altogether, maybe a stucco white coat with concrete bonder mixed in? I haven't tried it on OSB, but it works on previously painted block walls (I scratched the joints in with stucco base coat first, also with bonder added). The combination of the bonding additive (some kind of acrylic, I believe) and the mechanical key from the rough surface seems like it would hold pretty well. I'd probably staple some sort of mesh tape over the joints in the OSB first, and put one coat over those and let it set before going over the whole surface.

I have tried Fresco Harmony, both with regular mud and veneer plaster. Regular mud doesn't get much of a sheen to it; the plaster can, but it's a moot point if you're going over it with a sealer. There's a lot more color variation (light and dark spots) if you do it with the plaster, especially if you use a blister brush to finish trowel (not recommended by USG for pigmented finishes, but I'm not good enough to get a satisfactory surface without a wet trowel).

 

Make chalk paint with hotmud and low sheen paint.(as a primer coat). Another option is Westpack bluedot taping mud in a box, it will stick to anything and will have enough teeth for plaster.

 

Kids would love it.

 

First step is to bring your gas grill inside and hang pictures of girls on the walls. Well that's what we did when we built forts in the woods. Can't think of any other place I've seen osb as a finish material.

I wouldn't even be able to stand the look of it in a garage. At least spring for plywood and make a board and baton or something.
