I am in the middle of a bedroom remodel. The subfloor is old 1x boards and they have gaps between them anywhere from 1/8 to 3/8. I am currently laying down 1/2" plywood over the existing 1x boards, glueing and screwing the hell out of it. The problem is that you can feel a hump down the center of the house. Not sure how to measure this hump to give anyone an idea how bad it is. My question is, will this hump bother our hardwood floor install? I plan on putting 5/8 solid bamboo stranded flooring down. The flooring strips would run perpenducular to this hump. So, I wonder if the flooring strips would flex enough over this hump. The fact that it's stranded bamboo worries me with flexing.
