Big problem need advice...Remodeling again...(Flood Victim) I have a concrete sub-floor that has terracotta (spelling) was laid on top..What I have done in the past is put a layer of felt paper on top for a moisture barrier..(We live in the South, Very humid... Floor sweats..) I then put a layer of 3/4 " plywood on top and tried to use concrete nails to anchor down..In doing this in the past it is my experience that the Terracotta floor shatters under the plywood and we hear a squeek when we walk on the floor.. Like I said we have recently flooded and need to make changes in floor and I'm wanting to try something else..I see my big problem is trying to anchor plywood to Terracotta Floor..I was wondering if they had some kind of glue or something that I could anchor plywood to terracotta..My problem is needing some type of moisture barrier between the terracotta and the plywood..Is their a way that I could seal terracotta floor so that I would not need a moisture barrier...I need to get this done and I'm looking for something anything that will work.. Need help in Louisiana

hi, we hired a handyman to sand to refinish our Dade County pine floors, a type of heart pine. he used three coats of oil-based poly, but it's been a week and a half and they are still not dry. the floors are sticky and oily to the touch. we live in a very humid environment. the handyman won't help us (expensive lesson learned about more thorough reference checking), and mineral spirits won't budge the sticky finish. any tips? we'll be having extensive renovations done on the house, so it's possible we'll be refinishing again in a couple of years anyway (just needed to get rid of disgusting carpeting that was over the floors). is there any simple fix we can live with for a couple of years so we're not walking over an oil slick? thanks!
