Re: What should I use to fill large divets and small gaps in OSB subfloor?


I've never used this thicker product, but I did install a temporary sheet vinyl floor that was carpet-taped to the underlayment (which was not smooth-seamed). I was afraid the ringshank nails or seams would show, but they didn't. I did not, however, like the slight bubbling from either infiltrated air, heavy furniture, or house movement. These "floating" vinyl floors are great on concrete, I'm not sold yet on top of wood regardless of thickness.

It should be thick enough to hide any slight imperfections in the OSB, so leveller like others stated. I use subfloor glue in the non-T&G sides gaps as a backer rod.

My insistence on using underlayment for anything but 3/4" hardwood or carpet comes from years of removing other's flooring put directly on the subfloor. Houses always get remodeled, and I like to see an intact subfloor nailing patterns and all. But that was before you stated the subfloor is on a dimpled membrane in the basement, so I'm not sure an underlayment would matter much here.

Ah, those drains are on the big guys' premium products. Don't come across those as I only get to see cheap OSB eveywhere since those came to market.

That "drain" hole, how does that work in T&G, especially glued? Why would a ply manuf. design for POOLING water on a temporarily exposed subfloor? I have to look this one up, I still think its whack.



I was referring to the underlayment, not the finished floor. The whole post was related to installing underlayment.

Most likely this sheet was top or bottom of the pallet, metal band cut a groove.

No, they are drainage grooves. I think the OP has the sheet installed upside down though. The grooves prevent pooling of water on the end of the sheet. Also Chandler, OSB subfloors are very common in many parts of the country.

Another underlayment plus the floor is actually over 1/2", although technically out of code for riser but could get used to it.
But smooth underlayment is called for the kinds of flooring that are very thin. Traditional vinyl sheets or tiles that are little thicker than 1/16. 3/16, even if vinyl, seems thick enough to bridge some gaps, although maybe not osb edge joints that are different thickness. You could get the tiles and lay them without removing the glue protection and try walking over them. Also what does the manual say? You could even rent a floor sander and smooth down the osb. Bondo may be very stable filler for your situation.

1/4 underlayment actually measures about .200 plus or minus a little. Add in the 3/16 (.1875) floor and it comes to .3875, a little over 3/8". I honestly doubt anyone would notice the first step being 3/8 shy.

Yes some building inspectors can be anal, but my inspector doing final walk through's has never measured a stair step. Just walked up and down them to see how they felt.

That said, is there going to be a final inspection hear?

It's very doubtful that home inspector would flag a stair step being low by 1/8".


This is only MHO, I would not be worried about the stair step and use the underlayment. OSB just makes crappy underlay for vinyl. It compresses in traffic area's, tiles lift from delamination, and heaven help you if a little water gets spilled.
