I will be installing bruce unfinished 3 4 strip flooring this weekend.
Bruce hardwood over osb.
Tap tongue and groove sheets together with a hammer but leave a.
2 is there any advantage to.
Ensure that no fasteners are exposed or raised and that there is at least an 1 8 inch gap between osb subfloor panels.
There may be some exceptions to engineered floors that can be stapled down check product instructions.
My subfloor above grade consists of 23 32 sturd i floor osb over 24 oc joists.
Main concern is nails staples coming loose from the osb over time.
Osb that has absorbed moisture on the jobsite shrinks as it dries which can loosen around nails and staples that attach the hardwood flooring.
In the event the moisture differential between the osb and hardwood is too great at the time of installation problems can arise.
I would not install hardwood directly over osb.
Install 23 32 inch or thicker osb panels in the proper orientation that is with the side marked this side down facing down.
Hardwood flooring will not stabilize the osb subfloor so all movement must be remedied prior to hardwood installation.
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.
I ve heard of problems with nails not holding in osb all that well.
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.
