We just bought our first house, an old house, about 100 yrs. The floors don't seem to have any varnish at all, and have been covered with carpets until about 3 months ago. They are a beautiful oak, reddish in colour. We don't want to stain them, but want to finish them. Would you recommend this job for a first-timer? 3 bedrooms, all hallways, dining and living and stairs ... how long would this job take? Are we crazy or keen?
