A dining table takes everything: elbows, glasses, hot dishes, wine stains. No finish does everything; the choice is made on use, not on looks.
Oil — Pure Tung Oil, resistant to heat, water, alcohol and acids, or Wood Finishing Oil, the all-purpose oil for tables in constant use — leaves the wood matt and alive, and is repaired with a cloth, locally, without re-sanding the top. Hard Wax Oil Natural adds a wax that hardens at the surface: a spill-proof film, also repairable by area, for the table where the children eat. Quick Dry Varnish Kitchen and Bathroom Satin, a brush-applied water-based varnish, makes a hard, washable film that is repaired by whole coat. Special Pale Polish, shellac applied with a rubber, is the finish of antique table tops: unrivalled depth, but sensitive to heat and alcohol. The method in detail below is the oil route, the most widespread.
