Fading of Composite Deck Boards Versus Their Crumbling Due to Oxidation

FADING OF COMPOSITE DECK BOARDS VERSUS THEIR CRUMBLING DUE TO OXIDATION 

As it was noted above, antioxidants usually do not prevent fading. For instance, old (defective) GeoDeck boards which did not have any antioxidants and showed progressive deterioration, particularly in the South, retained their colors even when almost completely crumbled. 

This can be rephrased as follows Antioxidants can decrease fading to some extent and in some situations, but they do not prevent it. On the contrary, lack of antioxidants does not necessarily accelerate fading. Antioxidants often disappear from the very surface of a composite deck board rather quickly they would prevent
