Sorry I cant help, I'm not versed in wood floors. Does not seem like many stop in here to offer their advice. If you dont get an answer try http://boards.hgtv.com/eve/ and post with a request to Floor Guy. He knows his stuff on wood floors.

Thanks, how do I find Floor Guy?

Just start a thread there called something like Need Floor Guy's Help. He volunteers his time so if he does not answer fast he may be busy.
