The Pros Know
Two at a Time
When gluing OSB to I-joists, don't let too much time pass before you nail flooring down. Most glues will start to harden over. Not only does that create a poor bond, but it can cause a space for the flooring to move, which will cause a squeaky floor. Glue down just one or two panels at a time, and ensure nailing happens shortly after gluing.
