Before coating concrete, you must first know what the substrate is that you are working on. Since all concrete floors are not the same there is no one, size fits all system. In fact, many buildings will have several different types of concrete floors. Add to that the different mix designs, placement techniques and environmental conditions and you end up with a menagerie of concrete floors exhibiting a wide variety of properties.
Concrete is the second most common man-made material after potable water, yet it is a complex material that is poorly understood. Steel reinforcement is added to improve the concrete's tensile strength and ductility and is initially protected by the high concrete pH and depth of cover concrete. Eventually, due to the ingress of deleterious ions, lowering of the pH from carbonation, or electrical potential changes within the steel, corrosion will occur.
Concrete is one of the most durable construction materials available, but all too frequently we ignore its maintenance. Many of the techniques called "coating", "protection", and corrosion mitigation are, maintenance of concrete. The life span of concrete structures can be significantly extended by pro-actively addressing deterioration and durability issues through keeping water and other deleterious materials out of concrete after it has properly cured
