Color Hardener, as the name implies, forms a denser surface that is more durable and resistant to abrasion. This increases the lifespan and performance of the flatwork. Because it is a surface applied product, Color Hardener can also provide more flexibility. It can be used to color portions of a project without necessitating separate concrete orders (for example, a 9 yard job that requires two or more colors would only require one load of standard concrete). Furthermore, advanced techniques (even in conjunction with integral color) can yield different aesthetic effects such as marbling.
