Finish Coverage Guide

  • Wood stain: ~200 sq ft/quart, 1-2 coats typical
  • Polyurethane: ~125 sq ft/quart, 2-3 coats recommended
  • Lacquer: ~150 sq ft/quart (spray), 3-4 coats
  • Tung/Danish oil: ~100 sq ft/quart, 2-4 coats

Tips

  • Open-pore woods absorb significantly more finish on the first coat
  • Always sand between coats with 220-320 grit sandpaper
  • Raise the grain with water before applying water-based finishes
