We recently had a flooded basment and had to pull up the rug in my sons room. We found an old linolium tile floor that seems to have been installed directly on the concrete floor. It is very nasty and very uneven. I would like to eventually replace the carpeting, but that is not in the budget at this time. I thought maybe I could just sand it to rough up the suface and paint it with a good floor paint. Will this work?
