Like any surface exposed to the elements, composite wood is susceptible to fading, graying and warping. DEFY Composite Deck Sealer is available in a crystal clear finish and is designed especially for composite decks. It is highly resistant to mold and mildew, which helps the composite material to retain its natural color.
Before sealing, clean your composite wood with DEFY Composite Deck Cleaner. This will generally clean and restore previously treated surfaces to their original appearance.
