Your pool deck is one of the hardest-working surfaces in your Arizona backyard. It has to handle intense UV exposure, dramatic temperature swings between seasons, chlorine and water splashout, constant foot traffic, and — perhaps most critically — bare feet that can’t afford to land on a surface that’s been baking in 115°F direct sun.
Choosing the right material from the start saves you from premature cracking, costly refinishing, and the daily frustration of a deck that’s beautiful but impractical. Here’s a breakdown of the most popular pool deck materials for Arizona homeowners.
Kool Deck and Textured Acrylic Coatings
Kool Deck is the most widely used pool deck material in Arizona — and for good reason. This cement-based textured coating is applied over existing concrete and formulated specifically to stay cool to the touch even in direct sun. Studies have shown Kool Deck surfaces can be up to 30°F cooler than standard gray concrete on a hot day.
It’s also slip-resistant, durable, and available in a range of colors — from classic Sahara white to terracotta and earth tones that complement Arizona’s desert palette. The main limitation is that it will eventually need recoating (typically every 8–12 years depending on sun exposure and maintenance).
Travertine
Natural travertine is one of the most elegant pool deck materials available, and it has a unique property that makes it particularly well-suited to Arizona: its porous surface stays cooler underfoot than dense, solid stone. The natural air pockets in travertine reduce heat absorption, making it comfortable even on the hottest days.
Travertine’s warm, earthy tones — creams, golds, and soft browns — complement the desert landscape beautifully. It’s also non-slip in its natural tumbled or honed finish. The tradeoffs: travertine requires periodic sealing to resist staining from pool chemicals and organic debris, and it is a premium-priced material compared to coated concrete.
Concrete Pavers
Concrete pavers are a versatile, budget-friendly alternative to natural stone. Quality pool-grade pavers are engineered to resist UV fading, freeze-thaw cycles (yes, Arizona does get freezing temperatures at night in winter), and the repeated wetting and drying that comes with pool use.
One of the key advantages of pavers over poured concrete is repairability. If a section of poured concrete cracks — which is common in Arizona’s expansive clay soils — the repair is visible and costly. With pavers, individual pieces can be lifted and replaced without disturbing the surrounding area.
Light-colored pavers in tan, buff, or sandstone tones are the best choice for heat reflection around a pool. Dark charcoal or slate-toned pavers are striking but can become uncomfortably hot underfoot in direct summer sun.
Exposed Aggregate Concrete
Exposed aggregate finishes — where the top layer of cement paste is removed to reveal the embedded stone, pebble, or glass — offer a textured, decorative surface with good slip resistance. Lighter-colored aggregates (white quartz, cream pebbles, or tumbled river rock) reflect heat well and age gracefully in Arizona’s climate.
Exposed aggregate is a step up from standard broom-finish concrete in both appearance and durability. It’s a popular choice for larger deck areas where the cost of natural stone or pavers would become prohibitive, but you still want more visual interest than plain gray concrete.
What to Avoid
A few materials that look great in showrooms but consistently underperform in Arizona: standard gray broom-finish concrete (gets blazing hot, prone to cracking, stains easily from pool chemicals); wood decking (requires constant maintenance to prevent warping and cracking in extreme heat and UV); and dark natural stone like slate or black granite (absorbs too much heat to be comfortable barefoot in summer).
