I live in a 100 year old "camp" cottage in Massachusetts. Each of the 2 stories has southern yellow pine medium-wide floor boards running from end to end. The floor plan on the first floor is wide open. After 10 years here we are desperate to refinish the natural wood floors downstairs as they've been worn down with heavy traffic. They look as though they've been sanded many many times. I don't have a garage or attic to put my furniture in so I will need to crowd it from one end of the house to the other as I work.
I am looking for the most efficient and least toxic smelling way to approach this project. I am not a big project person - I just want to put some kind of finish on the floor. I would love to NOT sand the whole thing down, but rather, wash and coat. However, I have no idea what is currently on the floors.
