Hi Floor People, I have removed the original, very-thin tile and adhesive off a 75-year-old kitchen floor, and the "underwood" looks great. (I don't know if that's the subflooring or not.) Is there any reason why I can't just sand the wood and put Varathane over it? I don't know if the original (linoleum?) tiles were put down just for looks or for functional purposes. I would like to leave the wood -- unless there's a good reason why I shouldn't? Jean
