glue down hardwood flooring along gulf coast
I know this is an old post but thought I'd add what I've seen work.
I'm in Houston and a few friends have laid 3/4 hardwood over concrete. They put a thick plastic like used under concrete on the floor, then laid down 3/4" plywood diagonal to the finished floor, then put 30lb felt paper over the plywood, then nailed the hardwood to the plywood. Everything is floating over the concrete.
My brother did this with wide oak hardwood in a bonus room in his garage without air or heat about a year ago and hasn't had problems. Right now concrete around here is wet in the garage due to high humidity all week so I know his floor has seen plenty of humidity in the last year. He did say that it creaks a bit but I can live with that on a first floor. I'm getting ready to do about 1300 sq ft in my house like this.
Has anyone else used this method or seen this method fail? I'm going to use the maple since I bought it used from a reclaimed gym floor.
