Dad had Ash coming out of his ears at the mill (emerald ash borer blight) so he cut us a deal on some flooring…$1.25 a bd ft…only catch was we had to do all the work (milling from rough lumber, installing, sanding, finishing.) This took us most of July to complete but it was SO worth it. The finish is; Minwax oil-based stain (equal parts "Cherry" and "English Chestnut"), one coat of universal sealer (aka #2 lb cut of clear de-waxed shellac), and several coats of Sherwin Williams water-based polyurethane for floors.) I sanded with 320 before putting down the final coat. The guys at work tried to talk me into using Waterlox but I couldn't deal with the VOC's for an extended amount of time…the oil-based stain was bad enough. We have big labrador retrievers, though, and they've already scratched it up pretty good. I'm wondering if we shouldn't have gone with a finish that you can just add to as time goes by instead of having to sand and refinish 10-20 years down the road. Live and learn, eh?
