Polyaspartic Flooring Myths Nashville Homeowners Should Ignore

Homeowners researching polyaspartic flooring often encounter marketing claims that oversimplify how garage floor coating systems actually work. In Nashville’s humid climate, understanding what is myth versus fact can make the difference between a floor that lasts and one that fails early.

Myth 1: Polyaspartic Flooring Bonds Best When Applied Straight to Concrete

One common myth is that quick-cure polyaspartic (or polyurea) coatings can be applied as the direct-to-concrete primer coat and the clear top coat. This is how “1-day” coating systems are applied. In reality, while polyaspartic floor coatings excels as top coats, they are simply not recommended for direct to concrete application. Why? Because these coatings (i) go down thinly, and (ii) cure very quickly (in under an hour). As a result, the thin base layer doesn’t have time to deeply penetrate the concrete. 

Yet, all concrete naturally contains moisture, especially in Middle Tennessee. Without a base/primer coat that properly provides moisture mitigation, there is a significant increase in the risk of delamination (peeling). That is why professional systems always begin with a high-build (read “thick”) moisture-mitigating epoxy primer; it acts as a moisture vapor barrier designed to manage moisture that inevitably accumulates beneath the surface.

Myth 2: Epoxy Flooring Is Unnecessary

Another myth is that an epoxy floor coating is an unnecessary addition. In reality, epoxy remains one of the most important components of a long-lasting garage floor coating. A moisture-mitigating epoxy can be applied thickly…and it bonds slowly and deeply into the porous concrete. Unlike a polyurea-polyaspartic, it’s an ideal base coat and primer.

Epoxy floor coatings are also commonly used in indoor spaces where UV exposure is limited. While epoxy has lower UV resistance than polyaspartic products, its strength lies in creating a stable foundation beneath the surface.

Myth 3: A 1-day Installation Is Always the Best Choice

Some homeowners assume a 1-day system is automatically superior. In truth, the right timeline depends on concrete conditions. In most cases, a 2-day installation allows for moisture mitigation, better curing, and long-term performance. (2 days are often required because the epoxy primer is slower curing than a polyurea-polyaspartic). 

Myth 4: Polyaspartic Flooring Is Only About Looks

While polyaspartic coatings offers a clean, finished appearance, the real value is protection. Polyurea-polyaspartic coatings resist UV exposure, chemicals, and hot tire transfer, which is essential for active garages.

But it’s true that a complete garage floor coating system can also look beautiful. You can use our Live Coatings Visualizer to see for yourself, and preview how colors and flake blends would look in your actual garage or home.
