“Polished Concrete” is a broad term used to describe a wide variety of decorative concrete finishes.
To simplify this, we can break this down into two main types of finishes; Grind and Seal, and Mechanically Polishing.
Whilst both of these finishes can have similar methods of grinding the concrete, they differ in the way they are finished.
A grind and seal finish relies on a clear coating as the final surface (similar to polished floorboards). This protects and enhances the concrete underneath, and provides a hard-wearing surface. In most cases, these coatings will be either a polyurethane, an epoxy, or an acrylic. All of which have their benefits, depending on the intended use and desired look of the floor.
A mechanically polished concrete finish, also known as HiPERFLOOR or “True” polished concrete, is a system of grinding and hardening the concrete, prior to polishing it with progressively finer diamond grit. This leaves an extremely smooth, glass-like finish without the need for a topical clear coat. The main benefit of this being that the final surface is actually hardened concrete, which is extremely durable and resistant to abrasion when compared to a coating. The concrete will also remain a more natural color when compared to a topical coating.
Whilst not all concrete slabs are suited to a mechanically polished finish, a grind and seal finish almost always delivers consistent results on all types of concrete.
