DEFY Crystal Clear Composite Deck Waterproofing Sealer, 1 Gallon

Key item features

  • Clear Waterproofing: This water-based, clear composite deck sealer protects composite wood from sun damage without significantly altering its natural appearance.
  • UV Protection: Fortified with zinc nano-particles, the sealer reflects damaging UV rays, preventing premature graying and color loss in composite decks.
  • Durable Resin: Made with high-quality synthetic resins, this sealer offers enhanced resistance to fading and darkening, providing extended durability.
  • Mildew Resistance: The integrated zinc nano-particles also act as a natural deterrent against mold and mildew growth on the deck surface.
  • Easy Maintenance: For reapplication, simply clean the surface and apply a single maintenance coat; stripping is not required.
  • Application Coverage: One gallon covers 100 to 150 square feet, with a single coat recommended for horizontal composite deck surfaces.

Works for me

Used alot of different products over the last 30 years. Have kind of settled on this one because we prefer a clear finish. We live in Georgia under alot of trees. Deck accumulates alot of tree debris on one end and suffers from merciless sun on the other. Oil products grow too much mildew here. Still have to clean and redo after every 3 years or so....but offers decent protection. The story of deck owners!

Pricey, but worthwhile

Expensive, but about the only product that can protect composite decks. It lasts about about a year. This will be a yearly exercise, but worth it.
