DEFY Composite Deck Waterproofing Sealer is an extremely durable clear finish that helps prevent the return of black stains on composite decks as well as protect against the damaging effects of water, fungi, and UV radiation on composite wood surfaces. This V.O.C. compliant, water-based product is fortified with zinc nano-particles, a natural deterrent to recurring black algae stains. There are over 30 TRILLION of these zinc nano-particles per square inch that protect your composite wood by blocking out the sun's harmful UV rays, helping protect your composite deck from color fade, moisture and fungal growth.

DEFY Composite Deck Waterproofing Sealer can be applied to all natural and composite wood surfaces.

DEFY Composite Deck Waterproofing Sealer contains zinc nano-particles that reflect the damaging Ultraviolet Rays from the sun. When you reduce the size of these zinc particles down to the nano level, they become invisible to the naked eye. These nano-particles are distributed at a rate of over 30 trillion per square inch of surface area to provide protection from the sun in much the same way as they do when used in sun blockers and sunscreen lotions. Not only will this help with prolonging the graying, but the nano-particles are highly resistant to mold and mildew, enabling you to retain the natural color.

DEFY Composite Deck Waterproofing Sealer is available in a crystal clear finish.

DEFY Composite Deck Waterproofing Sealer is designed for composite decking including:

  • Trex
  • TimberTech
  • Azek
  • Fiberon
  • Evergrain
  • Duradeck
  • ChoiceDek
  • CorrectDeck
  • etc.

Before using DEFY Composite Deck Waterproofing Sealer, clean the deck with DEFY Composite Deck Cleaner. This will generally clean and restore previously treated surfaces to their original appearance. The surface should be recoated when graying initially starts to appear.

    Gary Sulivan told me that you have a stain made for composit decking. I installed ChoiceDek on my deck 4 years ago. It has been nothing but trouble, but my issue for you is the fact that it has changed color from a nice rich harvest brown to an ugly orangish tan. Can the sealer be tinted, or do you have a stain that works well on composite line ChoiceDek

    We have a ChoiceDek deck. Will Defy sealer penetrate this material so as not to create a film that will peel?

    This will work on all composite decking.

    Hi: I want to do the right thing, but I'm getting wildly different suggestions from potential contractors:
    1. Is Defy Sealer designed be applied to the floor of a deck made of pressure treated pine, with cracks?
    2. If so, is it a good idea to prep the floor boards with Deck stripper and brightener before applying the Deck sealer?
    3. Do you recommend applying a Defy stain over a deck that has been treated with Defy sealer?
    4. Any other caveats and suggestions would be appreciated.

    1. This is a composite sealer for composite wood. If you have a PTP deck, you would want the Defy Extreme Stain.
    2. You always have to prep first.
    3. You cannot apply a sealer over a deck stain or vice versa.
    4. You do not need both a sealer and a stain. Just the stain.

    I just painted my composite deck with Arborcoat Deck Paint, and I want to seal it. Will this product with over top of the Arborcoat Deck Paint? It was made to work with composite decks.

    This will not work over a paint.
