I'm involved in the laying of a floating commercial dance floor over concrete. It needs to last 10-15 years.
The plan is to glue a layer of pressure treated wood directly to the concrete. On top of that will be a layer of 2" thick neoprene. And on top of that will be two layers of plywood screwed to each other only, otherwise floating.
Can pressure treated wood be glued directly to the concrete or is it necessary to place a barrier between the treated wood and the concrete?
