Polyaspartics, also known as polyureas, and epoxies are two types of flooring coatings widely used in the construction and renovation industries. However, they differ in their chemical composition, properties, and applications. The experts at L’Artisan du Plancher offer you a brief comparison to help you make your choice.
Polyaspartic (or Polyurea) Polyaspartics are synthetic polymers often used as hardening agents in flooring coatings. They are typically derived from aspartic acid and can be modified to achieve various properties.
Epoxy Epoxies are thermosetting polymers that contain epoxy groups. They generally consist of an epoxy resin and a hardener, which chemically react to form a durable solid.
Polyaspartic (or Polyurea) Polyaspartic coatings generally offer excellent adhesion to substrates, as well as chemical and scratch resistance.
Epoxy Epoxies are also known for their good adhesion and chemical resistance, but they may be more susceptible to scratches and wear in certain applications.
Polyaspartic coatings generally have a shorter curing time compared to epoxies, meaning they can be applied more quickly and require less downtime. In terms of durability, polyaspartic (or polyurea) retains its clarity. It is also flexible and resistant to cracking due to concrete movement. Drying time: 6 hours for foot traffic and 24 hours before parking a vehicle.
Epoxies may have a longer curing time, which can require a longer period without traffic after application. In terms of durability, epoxy can yellow and deteriorate under UV rays. Drying time: Up to 5 days to fully cure after the final coat.
Polyaspartic (or Polyurea) Polyaspartics can offer some flexibility, making them suitable for surfaces where structural movement is expected.
Epoxy Epoxies are generally more rigid and less flexible than polyaspartics.
Polyaspartic (or Polyurea) Due to their fast curing time and chemical resistance, polyaspartics are often used in environments where quick turnaround is necessary, such as industrial facilities, parking lots, warehouses, etc.
Epoxy Epoxies are commonly used in a variety of applications, including commercial and industrial floors, as well as surface coatings for countertops, bars, and tables.
Although both polyaspartics (or polyureas) and epoxies are popular flooring coatings offering various benefits, they differ in their chemical composition, curing times, flexibility, and specific applications. The choice between the two will depend on the specific requirements of the project and application conditions.
