Very nice, I certainly am happy I decided a few months ago to go with 1x6x8' yellow pine and then milled the edges with tongue and groove cutters at work. The room is about 15'3" x 11'6"
The original floors are yellow pine, I should say they are really sub floors with only the dining room having had a top layer of flooring using 4" wide yellow pine. I had to replace the top floor in the dining room as it was covered with a layer of newspapers from 1949, then four layers of linoleum sheets, and painted around the 2' perimeter where the 9x11 linoleum didnt reach. Then on top of that was a 20 year old seasick green wall to wall carpet! The old floorboards were in horrid shape, common nails banged in, splits, holes cut for a basement furnace duct,and repaired with plywood, two burned spots from a coal hod maybe, and beside the odor of old linoleum and musty newspaper, it was filthy and never had been varnished or covered.
The new yellow pine ran me just 46 cents a lineal foot for 1x6 sanded 4 sides from the lumber yard. I applied 4 coats of water based polyurethane which I have usaed before with great results.
I plan to do the rest of the rooms the same way.
The pets have made some scratches, but as was pointed out, maybe once a year a floor can be given one thin coat of clear finish to renew the shine and all. Randall
