What is Polished Concrete
The Concrete Polishing Association of America has defined 4 types of polished concrete. It is important to understand the advantages and disadventages of each so that the correct process is selected to meet your expectations and budget.
Bonded Abrasive Polished Concrete
The processing of a concrete surface by means of a multi-step mechanical process that involves cutting and/or refining the surface to its maximum potential with a bonded abrasive medium where each step cuts progressively finer microscopic peaks and valleys until the desired level of reflective clarity and sheen is achieved. Depending on the client's wishes and at what grit level the process stops at, bonded abrasive polished concrete can have a matte sheen to a high degree of reflective clarity like a mirror.
Burnished Polished Concrete
The processing of the concrete surface through means of a mechanical process that uses abrasive nylon pads where each step is burnished until the desired level of reflective clarity and sheen is achieved. When compared to bonded abrasive polished concrete, burnished polished concrete's reflective clarity quality is diminished and has a lower degree of durability.
Topical Polished Concrete
The processing of the concrete surface through means of a chemical application that lays on top of the concrete surface. It is the topical chemical that creates the polish appearance and not a mechanical process. The durabilty, reflective clarity and sheen of topical polished concrete will depend on the makeup of the chemical.
Hybrid Polished Concrete
The processing of the concrete surface through means of a combination process that uses Bonded Abrasives, Burnished and/or Topical Polished Concrete. The durability, reflective clarity and sheen of hybrid polished concrete will depend on the combination of processes and makeup of chemical used.
