The type of Trex you have will determine how well your Trex deck can withstand Mother Nature. Trex Accents, Trex Origins, Trex Profiles, Trex Brasilia, and Trex Contours are examples of early generation composite decks that lack the high-performance shell with enhanced fade, stain, and mold resistance. As a result, these classic composites will gradually fade over time, reaching their aged color in 12-16 weeks. Trex Transcend, Trex Enhance, and Trex Select are newer generation high-performance composites with a protective shell technology that delivers exceptional fade and stain resistance.
