Does anyone have advice on installing engineered wood floors over a
concrete subfloor in a 6th floor condo? Do you recommend floating the
wood or gluing it down??? What about using a cork underlayment?


The manufacturer will have the best advice for their product. Floating
floors work well and are much more easily taken out 20 years later if that
is what you want to do. I used Mannington and they have an underlayment
just for it, one for above grade, another for below grade. Check
