My home has approximately 1200 sq ft of yellow pine (pretty sure that's what it is) hardwood floor from 1919. This summer I undertook the task of refinishing it. I didn't realize that it had been treated with boiled linseed oil (probably 100 years ago) and how much work it was going to take. After some reading and trial and error, the only way I've made any headway is sanding.

I rented a belt sander and edger and did the master bedroom first (~200 sq feet) at the end of the summer. It took me 12 hours of sanding as I didn't realize how far the linseed soaks into the wood. I just did the guest bedroom (~150 sq feet) this weekend which took me 9 hours of sanding. It takes about 4 passes with 20 grit and then 2 passes of 36, 60, and 100 grit respectively.

The overall result is wonderful and couldn't be happier. But is there a better / easier method? I have the main floor to do next (~750 sq ft) and am dreading it.
