Overview

DEFY Extreme Composite Deck Sealer delivers a crystal-clear finish that helps protect composite decks and natural wood from water intrusion while maintaining a true, natural appearance. The formula emphasizes long-lasting defense against moisture and UV exposure, so your outdoor surfaces stay vibrant without added tint or yellowing.

Key benefits

  • Waterproof clear deck sealer that forms a durable, transparent layer to resist stains and water damage while preserving the deck’s natural look.
  • Zinc nano-particles help mitigate fading, graying, and color loss, helping maintain the authentic color of your wood or composite surfaces over time.

Coverage, application, and dry times

On bare composite or natural wood, applying two coats typically yields coverage of about 100–150 square feet per gallon, depending on surface texture and porosity.

  • Easy application with a sprayer, brush, or pad applicator for flexible workflow and even spread.
  • Clean-up is simple with soap and water; recoat when graying initially starts to appear to refresh the finish.
  • Dry time ranges from 2–4 hours at temperatures above 45°F; plan for a 24-hour cure before heavy use.

Usage notes and care

Apply only to bare composite or natural wood surfaces. Do not use on painted or varnished substrates. For best results, ensure surfaces are clean and dry, and follow recoat guidance when you notice graying.

Made in the USA

DEFY’s deck sealer line is proudly made in the USA, combining quality ingredients with advanced water-repellent technology for outdoor protection.
