Bruce hardwood over osb. I ve heard of problems with nails not holding in osb all that well. In the event the moisture differential between the osb and hardwood is too great at the time of installation problems can arise. Moisture contents of osb subflooring must be established prior to hardwood flooring installations. 1 should i use barbed nails or staples.
Install 23 32 inch or thicker osb panels in the proper orientation that is with the side marked this side down facing down. Osb is fine as a subfloor structurally but imo it won t hold a nail or staple as well as spruce plywood. There may be some exceptions to engineered floors that can be stapled down check product instructions. Flooring is attached with staples to the subfloor which can be plywood oriented strand board osb high density particle board or even existing wood flooring.
Ensure that no fasteners are exposed or raised and that there is at least an 1 8 inch gap between osb subfloor panels. Especially if you are using a stapler to install the wood. A benefit to using staples over glue is that it can be walked on immediately. My subfloor above grade consists of 23 32 sturd i floor osb over 24 oc joists.
I would not install hardwood directly over osb. Main concern is nails staples coming loose from the osb over time. Hardwood flooring will not stabilize the osb subfloor so all movement must be remedied prior to hardwood installation.
