what type of subfloor for Hardwood

I am installing 3/4" Solid Hardwood into my living room. I've pulled the carpet and am beginning the prep work.

Some installers say that I can install directly on to the OSB Floor and not install subfloor. is this true? Should I lay down a subfloor on top of that prior to installing my hardwood?

What type should I use? how thick should it be?

the OSB on top of your floor joists IS your sub floor. Make sure it's secured properly and thick enough for your joist span to prevent sagging. Re-nail or screw if necessary.

I agree with this guy, thick sub floor is essential part for top flooring.

Are you agreeing with the original posters advisor? Or poster #2??

I am in the exact same position. Have nearly all my old flooring removed. The original wood floor I am removing was nailed right to the OSB with only tar-paper underneath.

What kind of sub-floor are you recommending??

If you have 3/4" osb you can staple or nail right to that---

How was the flooring that you removed? Was it holding well?

I prefer staples ---but never had a reason to fault the cleats---
My flooring guy uses staples and said that demolishing a stapled flood is much more work than removing a floor set with cleats---

The general recommendation I see from manufacturers is CD Exposure 1 grade plywood or OSB Exposure 1. minimum 5/8" thickness on 16" o.c joists or 3/4" thickness on 19" joists. Always satisfy manufacturer's requirements.
