None of that is suitable for a commercial installation. The old flooring has to be removed first, and then the subfloor prepped. A commercial level gluedown product from Karndean or Mannington would be my recommendation. Your local flooring supply house that handles contract level flooring is the best source. Your pro installer should have a relationship with them.

Thank you for that advice. We just talked to an installer today who said the same thing. Go figure :)
