Textured, UV stable finishes for the concrete you actually walk on barefoot.
Outdoor concrete in South Florida takes a beating that indoor slabs never see. Direct sun most of the year, chlorine and salt splash-out, afternoon downpours in summer, and bare feet on a surface that gets hot enough to matter. A coating that works beautifully in a garage can be entirely wrong on a pool deck, and the differences are worth understanding before you buy either one.
Three things drive every decision on an exterior deck: traction, temperature and ultraviolet exposure.
Traction comes first because it is a safety matter. A smooth, high gloss finish that looks superb on a garage floor becomes genuinely dangerous around a pool the moment it gets wet. Exterior work gets a textured broadcast, either a graded aggregate or a coarser flake, so the finished surface has grip underfoot when it is soaking.
Temperature is the one people forget until they are hopping across their own deck in July. Darker colors absorb noticeably more heat. Lighter blends stay meaningfully cooler under direct sun, and on a pool deck that is a comfort decision worth making deliberately rather than by accident.
Ultraviolet exposure is where product chemistry stops being an abstraction. Standard epoxy is not UV stable. Outdoors in Florida it will amber, chalk and turn brittle, sometimes within two seasons. Every exterior surface we coat gets a polyaspartic top coat, which holds its color under sun that runs most of the year.
If a contractor quotes you an epoxy pool deck in South Florida, that is a floor that will change color. Outdoors, the top coat has to be UV stable, and the texture has to be built in rather than added as an afterthought.
Exterior slabs have generally been exposed for years, which means the surface is contaminated in ways a garage floor is not. Chlorine residue, sunscreen and body oils, algae in the shaded sections, fertilizer overspray, and often an existing sealer or an old textured coating that has been recoated once or twice already.
All of it has to come off. We grind exterior concrete the same way we grind a garage, and previously coated decks usually need more aggressive tooling to get back to sound substrate. Hairline cracking is more common outdoors because exterior slabs move more with temperature, and control joints have to be honored rather than coated straight across if they are working joints.
Moisture testing matters here too, sometimes more. A pool deck has a body of water immediately adjacent to it and irrigation running around it, and the slab is often thinner than a garage floor. We test before we coat.
Exterior work is weather dependent in a way garage work is not. We do not coat when rain is likely inside the cure window, and during the summer rainy season that occasionally means moving a scheduled day. Slab temperature also drives pot life, so on very hot afternoons we adjust the cure speed of the base coat or shift the work earlier.
Most residential decks are a one day install. Larger decks with a lot of coping detail and step work can run into a second day, and we tell you that when we quote rather than on the afternoon of the install.
Bare, sound concrete coats at the same rate as a garage: $8 per square foot, with the same $2,400 minimum job. Most residential pool decks run 400 to 800 square feet once the surround and the walkway to the door are included.
| Area | Typical size | Bare concrete | To book |
|---|---|---|---|
| Lanai or covered patio | 250-400 SF | $2,400 - $3,200 | $240 - $320 |
| Pool deck, small | 400-600 SF | $3,200 - $4,800 | $320 - $480 |
| Pool deck, large | 600-900 SF | $4,800 - $7,200 | $480 - $720 |
| Front entry or walkway | 80-200 SF | Added to another job | - |

An existing coating has to come off before anything new goes down, and that is real labor rather than a hedge. Stripping an old acrylic, textured or painted deck adds $2 to $4 per square foot depending on how many layers are on there and how well they are still bonded.
We tell you which situation you have when we look at the deck, before you commit to anything. A bare or previously uncoated slab is the top table. A deck that has been recoated twice already is the top table plus removal.
Other things that move the price: extensive coping detail, multiple sets of steps with risers, a slab that fails the moisture test, and drainage work if water is currently sitting on the deck after rain.
Front walks, side paths and the run from the deck to the gate are inexpensive to add while the crew is already on site with the tooling out. Doing them separately later means a different batch on a different day, and the color will not match exactly.
A properly installed polyaspartic deck resists chlorine, salt, sunscreen and standard pool chemistry, and it cleans with a hose and a soft brush. It will not lift at the edges the way a peel-and-stick or a thin acrylic paint will. Traffic wear shows first in the highest use paths, typically the steps and the route between the door and the water, and those areas can be recoated without redoing the entire deck.
Eight dollars a square foot on bare, sound concrete, with a $2,400 minimum job. Most residential pool decks run 400 to 800 square feet. If there is an existing coating that has to come off first, removal adds $2 to $4 per square foot and we tell you that before you commit.
Not when it is built for outdoors. Exterior decks get a textured broadcast so there is real grip underfoot wet. A smooth high gloss finish belongs in a garage, not around a pool.
Every surface does, but color drives it more than product. Lighter blends stay meaningfully cooler under direct Florida sun, which is why we usually steer pool decks lighter.
Usually we take it off rather than coat over it. Old acrylic and textured coatings are the weak layer, and anything installed on top is only as sound as what is underneath.
No. A cured polyaspartic surface handles standard pool chemistry, salt systems and sunscreen without staining or breaking down.
