If you’re researching polyaspartic flooring for your Phoenix garage or home, you’ve probably seen epoxy mentioned alongside it. While these coatings are often discussed together, they serve very different purposes within a professional garage floor coating system. Understanding how each material works, and where it performs best, can help you choose a floor that actually lasts in Arizona’s extreme conditions.
How Epoxy Flooring Functions in a Polyaspartic Flooring System
A moisture-mitigating epoxy floor coating is known for its ability to be applied thickly and bond deeply to concrete. The epoxy cures slowly, penetrating the porous concrete slab creating a strong foundation for the layers that follow. (It acts as a moisture vapor barrier). That makes a moisture-mitigating epoxy an excellent base/primer coat, especially in garages where concrete moisture is a concern.
However, epoxy flooring is also commonly used indoors, where UV exposure is limited. While epoxy is highly durable, it has lower UV resistance, which means it can chalk or fade over time if exposed to Arizona sunlight. That’s why epoxy typically works best as the hidden workhorse beneath a full garage floor coating system rather than the final surface coat.
Why Polyaspartic Flooring Excels as a Topcoat
Once the concrete is properly prepped, primed with the moisture-mitigating epoxy, and the flake blend broadcast into the “wet” primer, application of the polyaspartic coatings follows. Polyurea-polyaspartic top coats cure quickly and deliver extreme resistance to UV rays, chemicals, oils, and hot tire transfer—critical advantages in Phoenix garages.
Because polyaspartic coatings are not recommended for direct-to-concrete application, they perform best as color and protective topcoats. These layers lock in durability, prevent discoloration, and maintain their appearance even in high heat.
Choosing the Right Garage Floor Coating in Phoenix
The best garage floor coating systems don’t force you to choose between epoxy and polyaspartic products—they use both, strategically. The moisture-mitigating epoxy builds the direct-to-concrete bond, while the clear polyaspartic coating protects the surface. Together, they create a long-lasting solution engineered for Phoenix’s climate.
