last two coats are going on my bedroom floor today, sure will be nice to stop sleeping on the guest bed in a couple/three weeks after the finish is cured ...and the trim is up...and the french doors are built for the sunroom...and the walls are painted...and the ceiling patched, plastered, and painted....and the closet doors built. well, ok, probably more like couple/three months, but progress is progress .
as with anything ~105 years old there's still some 'character' here and there, but all in all i think it cleaned up pretty good considering the shape it was in (two layers of carpet, both stapled down, lots of deep gouges from improperly moving furniture, and at some point a previous owner decided that paint store recommendation be damned, you can stain pine, you just have to pour the darkest stain you can find in the middle of the room and mop it around til the floor is black). the thresholds did not exist previously, there was just wide end grain gaps between the rooms from a century of shrinkage and settling. those are new boards set in (routed out the floor with a handheld router and set the thresholds in flush).
waterlox for sealer and top coat, garnet shellac in the middle for color (satin on top, just looks glossy cause it was applied today, still wet). these particular floor boards have gotten quite dark over their century in this house, so it only took one coat of the garnet to darken them quite a bit (other than the new thresholds which wound up taking 3 or 4 to match). other rooms are taking two or three to make them like this one.
