We are in the process of closing on a house. The house has been around for over 50 years and is a split level house. The upper level has wood floors (oak). There is wear and tear on the floor and we thought it would be best if we could refinish the floors (sand and coat) before we move in. We asked for quotes from a few local contractors and all the quotes mentioned polyurethane (oil based), most recommended 2 coats.
But here's the dilemma, on researching polyurethane, everyone agrees its toxic and not good to have around the house, especially with kids. I don't want to break the bank but also want to know if contractors generally work with the alternatives and what could be an expected price variation.
So, my question is, what are the alternatives or sustainable products to polyurethane for wood floor finishing?
