About Spray Deck
Spray Deck surface is what you see around almost all commercial pools. Of course, high-end hotels typically opt for a more glamorous look like stamped concrete.
Spray Deck (also called "Knock Down Spray Deck") installation involves spraying concrete through a hopper gun (similar to the textured ceiling application we are all accustomed to), then taking a flat trowel and knocking down the bumps.
People think that Spray Deck is a finish on the concrete (especially around pool decks) that is cooler to the touch than normal concrete. In reality it is cooler only because your feet touch about 50% of solid concrete, rather than 100%. With Spray Deck, the knock-down finish enables air to circulate under your feet, keeping them cooler.
