Interior Overlays & Toppings

We need a product to resurface a concrete pool deck in a community complex in Las Vegas. The summer heat is unbearable, and the concrete gets so hot you can't walk on it. I have heard about a product called Kool Deck, but pool stores tell me it's really just a paint. Can you recommend a product for our needs?


Those pool stores are wrong. Keystone Kool Deck from Mortex Mfg. is a not a paint. It's a spray-applied cement-polymer overlay available in light colors that will help to reflect the heat. It also has an "orange peel" texture that provides air pockets to help keep the surface cooler underfoot. The Las Vegas summer sun will heat up any surface, but a spray texture overlay in a light color will help quite a bit. These products have been standard coatings for pool decks in the sunbelt regions of the U.S. for decades. (See Resurfacing Existing Concrete with Pool Deck Coatings.)
