Thanks for your time in advance. I am very grateful for it. Our new house has hardwood floors. We need to sand and seal them. Someone came out to look today but his estimate may be more than we want to pay. My husband is extremely handy. He read up on how to do it using a sanding machine then a water based sealant. Can it work if you do it yourself? We are anxious to move in but need our appliances first, due July 5, our six foot fence finished for my doggies due to be done in early July and the floors need sealing since we do have dogs. We rented our apartment thru July and are in no rush. But then we WANT to move too lol. Any experiences on doing hardwood floors?
