Polyaspartic Versus Polyurea

Polyaspartic and Polyurea coatings are both popular options for protecting concrete surfaces. However, they have distinct differences that make them suitable for different applications. In this blog post, we will look at the differences between polyaspartic and polyurea coatings for concrete.

Polyaspartic Coating: Polyaspartic coating is a two-part system that consists of an isocyanate and a polyaspartic ester. This coating is known for its fast cure time and excellent UV resistance. It can be applied in one coat, making it an ideal option for large commercial projects where time is of the essence. Polyaspartic coating is also known for its high gloss finish, making it an excellent option for decorative concrete surfaces.

Polyurea Coating: Polyurea coating is a spray-applied elastomeric coating that consists of a two-part system made up of an isocyanate and a resin. It is known for its excellent chemical resistance and ability to withstand harsh environments. Polyurea coating is often used in industrial applications, such as on tanks, pipes, and concrete surfaces. Unlike polyaspartic coatings, polyurea coatings typically require multiple coats to provide optimal protection.


  1. Cure Time: Polyaspartic coating has a faster cure time than polyurea coating, making it an ideal option for projects with tight deadlines.
  2. UV Resistance: Polyaspartic coating is more resistant to UV light than polyurea coating, making it a better choice for exterior concrete surfaces that are exposed to direct sunlight.
  3. Chemical Resistance: Polyurea coating is more resistant to chemicals than polyaspartic coating, making it a better option for industrial applications where chemical exposure is a concern.
  4. Finish: Polyaspartic coating has a high-gloss finish, while polyurea coating has a matte finish. This makes polyaspartic coating a better option for decorative concrete surfaces.
  5. Application: Polyaspartic coating can be applied in one coat, while polyurea coating typically requires multiple coats for optimal protection.

In conclusion, both polyaspartic and polyurea coatings have their own unique benefits and drawbacks. The choice between the two will depend on the specific application, environmental conditions, and desired finish. Whether you are looking to protect your concrete surfaces or add a decorative touch, it is important to choose the right coating to ensure long-lasting protection and beauty.
