Cementitious coating refers to a type of material or coating that is primarily composed of cement, along with various other additives and sometimes fibers. This coating is used for a variety of construction and building applications. Here are some key features and uses of cementitious coatings: Composition: Cementitious coatings typically consist of Portland cement as the primary ingredient. Additional components may include finely ground minerals, polymer additives, and sometimes reinforcing fibers. The precise composition can vary based on the specific application and manufacturer. Waterproofing: One of the primary uses of cementitious coatings is as a waterproofing and protective layer for concrete and masonry surfaces. When applied correctly, these coatings can create a barrier that prevents water penetration and helps to protect the underlying structure from moisture damage. Corrosion Protection: Cementitious coatings can also be applied to steel and other metal structures to protect them from corrosion. The alkaline nature of cement helps to prevent the formation of rust on the metal surface. Repair and Resurfacing: Cementitious coatings are used to repair and resurface damaged concrete structures, such as bridges, parking garages, and other infrastructure. They can improve the structural integrity and extend the lifespan of the concrete.
