Q: I just bought a 70 year-old house. Iâ€™ve looked at the hardwood floors and they donâ€™t seem to be in too bad shape at all (there was carpet covering them). I want to bring them back to life. Do I need to sand them down or can I just throw a coat of varathane on them, or wax them?
A: I would strongly advise you to have a professional floor finisher in your area have a look at them. If the floor is an original wax finish without varnish or polyurethane, you can clean them up with a product such as Renovator from Dura Seal. www.duraseal.com. If they have a varnish/urethane coating, you might be able to have them buffed and coated. this can be risky, since you have no way to know what contaminants rest on the finish which could impede or prevent adhesion of another coat.
