Concrete etching is a cleaning process that opens the pores of the concrete to prepare the surface for the next treatment. This allows the coating to better penetrate and adhere to the surface, providing a better, longer lasting finish. It can also be used to create decorative patterns or designs on new concrete surfaces.Web
