Hey you flooring experts, I need some advice. I’m putting 3/4″ plywood sleepers over a slab floor (with my Hilti and PL400) in order to install a bamboo floor over it. The flooring is a uniform width and a 6 foot length. My client wishes to have some bounce to the floor so he can practice his karate on it. The options I’m entertaining are either to install the sleepers on the 24″ instead of on the 12″, or else to put some kind of ripped down foam sheets in between the sleepers and flooring. Anyone know what kind of rolled foam I would use? Would that option work?
