I am getting ready to frame our new house, subfloor is already down. How long can the 3/4 OSB T&G stand up to all the rainy weather we have had here in Ohio.
Thanks

15.7 seconds and then it's down hill from there.
I've seen OSB go through 16" of rain and only need some edge sanding.
A lot of guys around here spray Thompson's water seal on the subfloor as soon as it's down to help protect it.
I know of one guy who coveres his whole subfloor with Tyvek before he frames walls, and leaves it on until after the drywall is mudded.

When I was doing some work for Habitat we would put Thompsons down same day as the deck went down, never knew when it would get done.
On the flip side, the big track home builder in the area would put in about 30 foundations before winter and deck them, leaving them bare to the elements, then in the spring they would start building on them, sometimes, but not always, they would sand them, by that time they probably had a good 5/8" deck.
I wouldn't take one of those houses as a gift.
I wouldn't want to leave it exposed to the elements for very long but under normal building conditions it probably wont fall apart to fast, depends on what you call to fast.

Tyvek on the floors to protect them? That has got to be the most stupid, idiotic lame brained retarded moronic thing I have ever heard and that builder must be the most half-azzed stupid moron that ever walked and is probably the guy giving the rest of us fine homebuilders a bad name.
If some idiot did that to me, I'd show up to frame in spiked golf shoes. The slightest water makes tyvek slicker than snot on a doorknob, and they expect guys to walk, set ladders, and frame on that?
And the thomsons water seal deal.........talk about speeding the aging and breakdown rate on snot board.......I'm sure that's approved by the plywood council...........honey, I've smelled this strange smell since the house was closed in....kinda like thinner, or mineral spirits, and why is the carpet and pad discolored everywhere?
If you can get it under roof before it gets wet, use fir, if not use syp.

"...that builder must be the most half-azzed stupid moron that ever walked...
Based on what I know of him from working with him, and what I know of you from these forums, I'd put the 2 of you on roughly equal footings. Except maybe he's a little more open minded.................(-:
I helped that guy take one of his houses from foundation to shingles, and didn't find the tyvek to be slick at all. The only bad thing I noticed was that it wore through after a while in the doorway we used all the time.
Once the drywall was done and the tyvek torn up, the subfloor looked as good as the day it was put down. No drywall mud to scrape off the subfloor.
Using water sealer on the subfloor also seems like a good idea to me. I did it on my spec house. There never was an odor that I can remember. Of course - I didn't put 20 or 30 gallons on - Just enough to soak into the top.
Why is it that you so aggressively attack ideas that you don't agree with? Lighten up a little.Who are you going to believe, me or your own eyes?
BS boss...first rule of wet construction...when it' wet, don't step on plastic tarps, lumber wraps or tyvek. You'll fall and break something you need to feed your family. Thomsons is pariffin in solvent....spread it on anything you want, but not that super absorbant, held together with glue resin POS snot board.
And in case you don't know, I don't give a flying F what you think of me.
boss... the tyvek may have kept it clean.. but it sure didn't do much for keeping it dry.... god had more to do with that... one little hole and the tyvek will be worse than useless... any holes and the water will get thru... then the tyvek will prevent drying to the top..
so .. tyvek on subfloor.. no way.. no how...
want to stop worrying about subfloor gettting wet ?.. switch to AdvantechMike Smith Rhode Island : Design / Build / Repair / Restore

use the osb behind your tub tile. you will save a bunch of money... lol
My sister's house lasted 3 rainstorms before every butt end of every sheet swelled to !" thick. The builder told her that it was no big deal. 20 months later and the hardwood floor squeaks like a bitch. OSB is pure crap. Do yourself a favor and use Advantech on the second floor deck.

I frame in the PacNW and we get RAIN. We have used OSB for the last 15 years and never once have had to sand it. I'm serious. I don't know what it is, but we haven't had any problems. Now it does swell, but we haven't had any problems with our sublfoor.
This last march, the subfloor was wet on this house we framed for about 1 month straight. No problems with it. We have been using LP TopNotch and for the last 10 months, we've used the Gold Edge by Weyhauser.
Personally, you should get the roof on and dried in as quickly as possible and don't leave it sitting in the rain.
Have you thought about Advantech? I'm itching to try it myself.
We are in NKY and we use Avantec. It seems to hold up well. If you did not use that or an equivalent once you get it dried in use a dehumidifier and sand the seams.
