Most of the Orange Aprons I’ve talked to say that you should never glue parquet down onto oriented strand board, only on wood or plywood. I checked a couple of buckets of (latex) glue at the stores, and some of them do state on the label that OSB is not an acceptable substrate
So, is this just another urban myth, or is there something to it? Has anyone had any difficulties in this department? Or other comments?
Thanks

I use fine-thread drywall screws to hold hardwood parquet down to OSB. Glue seems overkill when you do it this way

That's from underneath, right? (G)
Hmmm..... That will sure wreak havoc with the foamboard underneath the slab

There's OSB and then there's OSB, and then again, OSB is...
the original OSB "Waferboard" isn't good for anything, even a dog house.
The OSB we get now is a little better for sheathing but the jury is still out for horizontal applications like roofs and floors.
Advantec subfloor material looks a lot like OSB but is superior to plywood in most ways.
-----All of these get called OSB but not all of them are.
The two concerns would be structural - will it move and sag and imntegrity - will it delaminate and produce bad bonds?
Since the wafers are glued to gether, I would speculate whether the glue manufactures are afraid of chemical reactions.

I'm doing some work in a new house under construction, and they are using Advantec. First time I had seen it. Heavy. Seems well made. What makes it better?
I don't know.
Frame this post! Jencar asked last night if there is anything that I don't know.
I suppose it's the type of glues or resins they stick it together with or it could have to do with the pressure applied and the curing process.
I'm sure another thread titled, "What makes Advantec better" could bring an answer. It's practically waterproof. Weathers real well without delamination..

Depends on whether the adhesive is solvent or water based.
You get water (latex) near OSB and it will move, and so will the parquet.
A solvent based adhesive will not expand and move the OSB, although the OSB will need a NIOSHA respirator with activated charcoal filters, and so will you, or you will both get sick, and die horrible construction related deaths.

...Or risk being so high you can't reach the floor, maybe?
Good point, though. Thanks

I remember one restaurant floor that left me quite happy for a day or so - untill the hangover hit!
It was twenty below outside so I didn't ventilate and I was working alone all night long to accomadate schedule. I realized later that they could have found me prone and without a heartbeat, but with a smile on my face..
