Epoxy and Polyaspartic: The Pros and Cons of the Two Best Concrete Coatings

On October 30, 2023

Polyurea and epoxy flooring are two popular options for concrete coatings, and each has its own properties and advantages. Understanding the differences between these two flooring solutions can help you make a more informed decision when it comes to choosing the right flooring system for your needs.

In this article, we will make a side-by-side comparison of polyurea and epoxy flooring to help you get a better idea of what you can expect from each of these concrete coatings.

Epoxy or Polyurea?

There are several key differences between epoxy and polyurea concrete coatings, but it’s difficult to say which one is better. However, with highlighting their differences, we can see how each of these options might perform better under different circumstances.


Polyurea Flooring – Polyurea is a type of polymer that is formed through a chemical reaction by blending an isocyanate component with a resin mixture. Polyurea is known for its fast curing time, which makes it an ideal choice for projects that require a quick turnaround.

Epoxy Flooring – Epoxy flooring is created by mixing up an epoxy resin with a hardening agent, which results in a rigid and highly durable finish. Epoxy typically has a longer curing time when compared to polyurea.


Polyurea Flooring – Polyurea is well known for its exceptional durability, and it is highly resistant to abrasions, impacts, and chemical exposure, which makes it suitable for a wide range of industrial and commercial applications. Polyurea can also withstand heavy traffic and harsh environments.

Epoxy Flooring – Epoxy flooring is also durable and able to withstand heavy foot traffic, as well as moderate industrial use. However, it may be more prone to chipping and delamination under extreme conditions.


Polyurea Flooring – Polyurea is extremely adhesive, which allows it to create a strong bond to a concrete substrate. This results in a strong surface, but it is more difficult to create a seamless finish with polyurea due to its fast curing time.

Epoxy Flooring – Epoxy concrete coatings also provide strong adhesion, but it may require additional surface preparation to ensure a strong bond. In some cases, epoxy may be more sensitive to surface contaminants, which can affect its ability to adhere to the substrate.

Chemical Resistance

Polyurea Flooring – Polyurea is known for its superior chemical resistance, which allows it to withstand exposure to many different types of chemicals without significant degradation. However, if your polyurea flooring is exposed to a strong acid or solvent, it’s best to clean the surface as quickly as possible to preserve your floor’s integrity.

Epoxy Flooring – Epoxy coatings also provide substantial chemical resistance, but they may require additional top coats or specialized formulas to enhance their resistance to certain chemicals.

UV Resistance

Polyurea Flooring – Polyurea flooring tends to be a more popular choice for outdoor applications since it provides superior resistance to sun exposure. Even when exposed to direct sunlight every day, polyurea concrete coatings will not discolor or degrade.

Epoxy Flooring – Epoxy flooring tends to be more suitable for indoor applications due to its UV sensitivity. Over time, epoxy flooring can change color and take on a slightly amber tone when it is continuously exposed to direct sunlight.
