ere are the cold hard facts about polished concrete.
Polished concrete floors are known for there superior durability, however, they are not impervious to staining, scratches or chips. This is a finished floor system, and must be treated as such. It is imperative that a polished concrete floor be kept clean. Although it is an extremely durable surface, dirt, sand and other contaminants, will act as a sandpaper by abrading the polish over time. Floor mats placed at entrances help minimize the tracking of contaminants onto the surface; these mats should be maintained and kept clean.
Using concrete with a low water-cement ratio and not adding excess water at the jobsite will help to keep shrinkage in check.
