The unyielding shell of our high-performance decking—Trex Transcend Lineage, Trex Transcend, Trex Enhance and Trex Select—means it never needs painting or staining. The rich color and protective finish are engineered right into the shell, and the shell is designed to remain free of rotting, splitting, splintering and insect damage for the duration of the warranty. Not to mention, painting Trex decking may void your warranty.
