I recently bought a house with a 2 story garage. the upper floor is 30 X 24 and open. the lower is divided into bays 20 X 12 with a 10 X 24 room on the back. The floor joist are true 2X6 on 24" centers. the garage is balloon framed with the floor joist nailed the outside wall studs and the centers resting on the dividing wall between the bays. the Floor itself is 1X6 shiplap planks
The floor has a lot of bounce when you walk across it and I would like to get rid of it. I have been trying to decide on one of two ideas.
1 remove all the wiring from the existing floor joist and install 2X8 resting on another 2X8 nailed to the existing framing and blocked between.
2 add 1X6 boards to the existing floor
I'm thinking #1 is the proper way to go
Thanks for your help
