Epoxy has been around since the 1930's and has been an industry standard for durable industrial flooring. Polyurea was created as a coating much later. The choice between the two depends for floors depends on the specific requirements. Epoxy is known for its durability, chemical resistance, and versatility. It creates a hard and glossy surface that is resistant to stains, impacts, and abrasion. Polyurea on the other hand is a bit more flexible and fast curing (something we here at Big Top Concrete Resurfacing, LLC are not too fond of). Polyurea coatings can be applied in a wide range of temperatures and adhere well to various substrates, including concrete. IN Summary, epoxy is a popular choice for its durability and versatility, while polyurea offers faster curing times and excellent resistance properties, and flexibility. It is important not to get caught up in the gorilla marketing tactics of companies touting one is 20x stronger than the other. They both have their place in the coatings market but truthfully polyurea sets fast and that is why many companies use, to get the job done quickly. This is not our preferred method, yes speed is important but being thorough and giving material time to absorb is much more important.
