This finish is typically used on existing floors that may be badly damaged or already covered with various products such as paint, glue, epoxy, tile-adhesives etc.
The concrete is first ground to eliminate any damaged or unwanted products from the surface exposing the good concrete underneath. A densifier is then applied to harden the concrete before finally being polished.

The major benefits of this process being that due to the reflectivity of the polished surface, the amount of lighting required can be reduced as much as 50%.
Polishing a commercial floor consists of applying a densifier to harden the concrete and polishing the concrete to create an extremely durable and reflective floor.

Polished concrete is a far superior finish for heavy traffic facilities as oppose to epoxies, paints and virtually any floor covering. When combining good quality concrete and then polishing it you will get a surface that is near bullet proof, looks great and will last a lifetime.
