What is cellular PVC or Vinyl decking and how is it different from Composite decking?
.
Cellular PVC decking was formerly considered Composite decking. In most cases, PVC is a much higher end product than standard Composite decking. Composite decking now is made up mostly of cellulosic (wood dust) material and polypropylene or other recycled plastics. DeckMAX™ was developed for PVC decking and will not bring back the color of faded polypropylene or other recycled plastics. A rule of thumb is if you see organic material in your deck board it is a composite deck, not vinyl PVC.

Please consult with your decking manufacturer to determine the make-up of your deck and to see if DeckMAX™ is right for use on your decking material.
