a. Try to scratch the surface of the Azek and competitor boards with your fingernail.
b. Then, drag a key across both boards, using slight pressure. Try again, using more pressure.
c. Notice the superior grain retention and scratch resistance of the Azek board.
This scratch test demonstrates how resilient the Azek surface is, which ensures grain retention as well.
Typically, many composite boards will lose grain in high-traffic areas. In fact, many manufacturers recommend "No Power Washing" because this may remove protective polymers. The Azek surface features a unique Celuka top-layer that is fusion-bonded with the board during the manufacturing process so it won't wash off... and you can enjoy your deck without worry.
a. Apply a quarter-size amount of BBQ sauce, cooking oil or ketchup to the Azek board. Let it soak in while you make the same application to the competitor board.
b. Wait 15 minutes, blot the competitor board and wipe dry.
c. Leave the spot on the Azek board for as long as you'd like, then blot and wipe the board dry.
Azek's vinyl deck formulation does not harbor mold, which is a major problem in the decking industry today. To combat this problem, many competitor boards are coated with a polymer for stain protection, but this coating diminishes when exposed to the elements.
Azek decking materials are engineered without wood fillers so that the surface resists stains and mold from the inside out.
