There are a few key differences between epoxy and polyurea that can help you decide which is the best option for your needs. Epoxy is typically stronger and more durable than polyurea, making it the better choice for high-wear areas. It is also more resistant to chemicals and heat, making it ideal for use in industrial settings. Polyurea, on the other hand, is more flexible and can be applied in a thicker layer, making it better suited for projects that require a waterproof seal. It also dries faster than epoxy, so it can be a good choice when time is of the essence.
