What is Polished Concrete
Polished concrete… …is not terrazzo
Bonded Abrasive Polished Concrete Defined Result of processing a concrete floor surface with bonded abrasives until the desired class of aggregate exposure and the desired level of glossy finish are achieved
Benefits • Permanence • Low maintenance • Reflective surface reduces need for lighting • Dusting and particulate debris elimination
Benefits • • Abrasion resistance Stain resistance Slip resistance Cost-effective lifecycle
Art and Science of Polishing Concrete
Art • Skill of polishing contractor to “read” concrete and “listen” to equipment • Experienced to deliver finish that meets desired design intent
Science • • • Specifications Concrete quality Polishing equipment Chemicals Quality of surface finish
