This is due to polyureas extreme flexibility, elongation, dense cross-linking, and mar resistance. Polyureas can take a tremendous amount of abuse because they are malleable and can take the physical impacts and disperse them, much like the rubber on a car tire.
Polyureas are 98% more flexible than typical Epoxy/Hybrid floor coatings. This flexibility is key during the summer when the California heat reaches it's peak. Polyureas, being as flexible as they are, expand and contract with the concrete leaving the surface strong and intact.
Polyureas are more chemically resistant to a much wider range of chemicals than epoxy surfaces. This is due to their densely cross-linked chemistry. From Salt, Oil, Gas, and Grease, to Acids, Skydrol, Hydroxides, Polyureas will stand the test of time. Polyureas are also 100% UV stable.
