Concrete grinding is also known as concrete polishing and it is the process in which concrete flooring is polished to a specific level of grit by a concrete densifier and grinder. There are instances where flooring needs to have grit so that the coating that follows can hang on to the concrete floor. The grit size is going to vary, such as an ...
They are used to grind down the concrete surface to achieve the desired degree of smoothness and shiny texture in the concrete. Like the process of sanding wood, when the grinder moves on the concrete surface, it produces fine particles of concrete dust due to grinding. After removing the concrete dust, a fine mirror-like glossy finish is obtained.
