Bare gray concrete can hit skin-scorching temperatures in summer sun. Cool-deck coatings fight back with light, reflective pigments and texture that bounce heat away and expose less surface to your feet. Here are the coatings that actually lower deck temperature — and a realistic look at how much cooling to expect.
The original Tucson-born cool-deck topping, a cement-based, acrylic-modified mix you tint and trowel over concrete to drop a scorching pool deck's surface temperature and add a comfortable non-skid texture. Unlike roll-on coatings it is a genuine masonry job: mixing and troweling take skill, it bonds best to fresh or well-prepped slabs, and you will likely source it from a pool-supply specialist rather than a home center.
- Cool underfoot
- Pool decks
- Heat reduction
- Non skid
Pros
- The original cool-deck topping — light color and texture cut surface heat markedly
- Cement-based topping is harder and more durable than a thin paint film
- Non-skid mottled texture is comfortable and safe around a wet pool
Cons
- Mix-and-trowel cement application is labor-intensive and skill-dependent, not roll-on
- Best bonded to fresh or properly prepped concrete — retrofit prep is demanding
- Sold mainly through specialty pool suppliers, not big-box stores
A water-based, self-crosslinking acrylic engineered to reflect UV and lower a concrete pool deck's surface temperature by up to about 20°F while resisting chlorine and salt exposure, and it covers far better than most textured coatings. Be realistic about the physics: the cooling is real but modest and depends heavily on using a light color and full sun conditions, and it is a premium, Sherwin-Williams-store product rather than a budget big-box buy.
- Heat reflective
- Pool decks
- Chlorine resistance
- Hiding imperfections
Pros
- Cool Feel technology reflects UV to cut surface temperature by up to ~20°F
- Self-crosslinking acrylic resists pool chemicals and household stains with a UV-fade shield
- Higher coverage (~200-300 sq ft/gal) than most textured pool-deck coatings
Cons
- Real but modest cooling (~20°F) that varies with color, sun and ambient heat
- Maximum cooling needs lighter colors — deep shades reflect less and run hotter
- Sold through Sherwin-Williams stores, not big-box, and priced at the premium end
A tough, water-based acrylic coating whose speckled texture adds real underfoot grip on wet pool decks and patios while filling hairline cracks and resisting hot-tire pickup. The honest trade-off is coverage: at roughly 50 sq ft per gallon in two coats it eats product fast, and like any film coating it only lasts if you fully etch and clean the concrete first.
- Pool decks
- Patios
- Slip resistance
- Hiding hairline cracks
Pros
- Textured multi-speckle finish is genuinely slip-resistant when wet
- Fills hairline cracks and hides surface imperfections in the concrete
- Water cleanup and resists hot-tire pickup, grease and household stains
Cons
- Very low coverage (~50 sq ft/gal) means you buy and roll a lot of product
- Demands thorough etching/cleaning prep or it will peel from smooth concrete
- Limited stock color range and speckle look is not to everyone's taste

Frequently Asked Questions
- How much cooler does a cool deck coating actually make concrete?
- It depends on color and sun, but manufacturers cite real reductions — H&C Cool Feel claims up to about 20°F, and textured cement toppings like Kool Deck can feel dramatically cooler than bare slab. Lighter colors reflect more heat, so shade choice matters as much as the product.
- Does the color of a cool deck coating matter?
- Yes, a lot. Light, reflective colors bounce away solar heat while dark colors absorb it, so a dark 'cool' coating largely defeats the purpose. For the coolest bare-foot surface, choose the lightest color that suits your deck.
- Is Kool Deck the same as an acrylic cool deck coating?
- Not exactly. Kool Deck is a cement-based topping you mix and trowel on, giving a durable masonry surface, while products like H&C Cool Feel are roll-on acrylic coatings. The cement topping is tougher but a harder, more skilled install; the acrylic is far easier to apply.
