If you’re researching ways to upgrade a cracked, discolored pool deck, you have likely come across epoxy flooring. Epoxy is a household name, and it performs incredibly well in climate-controlled indoor environments. But when it comes to outdoor applications like pool decks, lanais, and patios, applying traditional epoxy is a costly mistake.
At Poly Shield Coatings, we frequently meet homeowners who are living with the consequences of an outdoor epoxy project gone wrong. Within just a year or two of exposure to the sun, their beautiful floors have turned an ugly shade of amber, started chalking, and begun to peel.
Here is the scientific reality behind why traditional epoxy fails outdoors, and why Poly Shield Coatings uses an entirely different system to guarantee long-term success.
The Problem with Epoxy and Solar Radiation
Traditional epoxy is highly sensitive to ultraviolet (UV) light. When the sun’s UV rays hit an epoxy coating, a chemical reaction occurs that breaks down the polymer chains within the material. This degradation manifests in a few distinct, frustrating ways:
- Yellowing (Ambering): Clear or light-colored epoxies will rapidly develop a yellow, muddy tint, ruining the aesthetic design of your pool deck.
- Chalking: The surface of the epoxy will degrade into a fine, powdery residue that transfers onto your feet, shoes, and pool towels.
- Delamination: As the chemical bonds weaken from constant UV exposure and thermal expansion, the coating loses its grip on the concrete and begins to lift, crack, and peel.
The Poly Shield Coatings Solution: Next-Gen Polyaspartic Technology
Outdoor concrete coatings must be engineered to withstand brutal heat and continuous sunlight. That is why Poly Shield Coatings bypasses standard epoxy entirely for outdoor spaces, utilizing a premium polyurea and polyaspartic flooring system instead.
Unlike epoxy, our polyaspartic topcoats are 100% UV-stable. They are chemically formulated to resist solar radiation, meaning they will never yellow, fade, or chalk, regardless of how many hours of direct sunlight they endure. Your pool deck will look just as vibrant and colorful in ten years as it did the day we finished the installation.
Flexibility Matched with Climate Realities
Outdoor concrete expands and contracts as temperatures rise during the day and drop at night. Epoxy is rigid and brittle; when the concrete underneath moves, the epoxy cracks.
The advanced coatings applied by Poly Shield Coatings are highly flexible. Our polyurea base coat penetrates deep into the pores of the concrete, establishing a mechanical bond that is four times stronger than epoxy, while remaining flexible enough to move with the slab during temperature swings.
Don’t waste time and money on a temporary fix that the sun will destroy. Choose Poly Shield Coatings for an outdoor concrete coating designed to go the distance. Reach out to our team today to explore our wide variety of UV-resistant color flake styles.
