Cool Deck and textured acrylic are two different things. Cool deck is porous, it stains easily, is more likely to peel. It is also cooler than the much more durable textured acrylic coatings. They are often confused because, although textured acrylic can be made to simulate almost any surface, the most common finish is the Spanish lace, which looks like cool deck. Other than a very slight difference in the surface sheen the two would look identical, but they do perform different.
I have had textured acrylic coated decking for 12 years. Maintaining it properly does require touching up any cracks or chips and re coating the color top coat every few years.That seals it, prevents water getting under and peeling, and renews the wear surface. I have done the complete deck once and it cost me $150 or so for material and one day to finish. After 12 years, the deck looks just like the day it was first put in. All in all, I'm very happy with my choice.
