My family room floor has too much bounce for my taste. House is 4 years old. Span is 16 feet with 2x10's on 12 inch centers. Cross bracing every four feet. The flor is fully exposed from basement below so I can do just about anything that would work.
Someone suggested screwing and glueing plywood to the bottom of the joists to stiffen. I'm about to begin a proejct to finish the basement and am considering taking the time & expense of attaching 3/4" plywood instead of strapping to at least the center section of the floor. The contractor we talked with said he's never seen that done but "worth a try".
Anyone ever done/seen this before? Do you think this will work? Or should I just go with additional blocking and hope that works?
