Hi Al,
Welcome to the forums. If you check in the Techniques thread of the forum, there is a FAQ thread all about Future floor wax. I would try to answer your question for you, but as Im not 100% sure of the answer, the best I can do is direct you to where I think you can find the info you need.
Good luck
