The question first: What are the pros and cons of poly vs. wax? We're remodeling the third floor (we've used it as a storage attic) of our 200-year-old house. The wide pine floorboards are in pretty good shape, just very dull and dirty and stained in a few spots. Contractor says we should sand and poly (which we did on downstairs oak), but I'm wondering if that will look too new and shiny. Would it be better for these ancient boards if we just sanded, maybe applied some kind of shellac sealer and then used paste wax and buffed? This would not be a high-traffic area. (Our second floor, pine and walnut, was never poly'd, but keeps a nice mellow sheen with occasional buffing.) Anybody?
