Product Datasheets

DEFY Composite Deck Sealer is an extremely durable clear finish that helps to 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 to protect your composite deck from color fade, moisture, and fungal growth.

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

DEFY Composite Deck 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 in sun blockers and sunscreen lotions. The nano-particles' high resistance to mold and mildew will not only prolong the return of graying, but will enable you to retain the natural color.

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

Easy Push Brush Application

For easy fast application use a car wash brush available at most home improvement stores.
