You may or may not remember that we took a different route when finishing our wood floors in our home. Instead of installing pre-finished floors or using polyurethane, we chose to finish unfinished yellow pine with pure tung oil. And in the two years we've been living with these floors, we have received hundreds of questions about how they are holding up. I guess we aren't the only ones who are interested in this beautiful, natural, nontoxic finish.
