Bruce Hardwood Over Osb

I will be installing bruce unfinished 3 4 strip flooring this weekend.

Bruce hardwood over osb.

Main concern is nails staples coming loose from the osb over time. In the event the moisture differential between the osb and hardwood is too great at the time of installation problems can arise. My subfloor above grade consists of 23 32 sturd i floor osb over 24 oc joists. Osb that has absorbed moisture on the jobsite shrinks as it dries which can loosen around nails and staples that attach the hardwood flooring.

2 is there any advantage to. Tap tongue and groove sheets together with a hammer but leave a. 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.

There may be some exceptions to engineered floors that can be stapled down check product instructions. 1 should i use barbed nails or staples. Osb is fine as a subfloor structurally but imo it won t hold a nail or staple as well as spruce plywood. A benefit to using staples over glue is that it can be walked on immediately.

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. Hardwood flooring will not stabilize the osb subfloor so all movement must be remedied prior to hardwood installation.
