I have a 3/4" T&G pine floor directly on the joists (no subfloor). Can't replace it since the boards go under the walls.
I'm thinking of laying another wood floor on top. I'm a big guy and tired of feeling like I'm tip-toeing around.
What is the minimum thickness of underlayment to strengthen/ remove squeaks?
I'm thinking 1/2" ply glued and screwed, but also don't really want to raise the floor more than than necessary.
Any ideas? Thanks.
