Pro Tips

  • ✓ Allow new pressure-treated wood to dry 6–12 months before staining — the chemicals need to cure
  • ✓ One gallon covers ~200 sq ft per coat; weathered wood is thirstier and may take more
  • ✓ Deck brightener lowers wood pH after cleaning and opens the grain for better stain penetration
  • ✓ Stain in shade or on a cool overcast day — direct sun causes lap marks and uneven drying
