Concrete coating refers to the application of a protective layer over a concrete surface. This layer can enhance the appearance, durability, and functionality of the concrete. Common types of coatings include epoxy, polyurethane, and stains, each offering different benefits such as resistance to chemicals, UV light, and wear. The process of applying a concrete coating typically involves cleaning the surface, repairing any damage, and then applying the chosen coating material. Proper application can help prevent issues like cracking and staining, making it a popular choice for both residential and commercial spaces.
