Polished Concrete Flooring

A lifetime floor, polished concrete is great way to get that professional, modern, and highly durable look that captures the eye.  Through the process of mechanically honing and chemically densifying the concrete stone surface so tight that it is sealed onto itself.

What is Polished Flooring? 

First to explain polishing; polishing is the act of honing a surface to tighter, smoother, surface which is often more reflective to light and denser the tighter the surface.  Mechanically polishing concrete is basically using diamond infused metal, resin, and other materials pads in incremental steps from course to fine, with chemical densifiers and sealants, as well as fillers, to polish the concretes surface.

What is the process of Polished Concrete Flooring?

Depending on the level of sheen or gloss desired, the actual steps it takes to polish a concrete floor from start to finish vary from 10-15 steps in total.  The process begins with mechanically grinding with metal bonded diamonds to open up the surface, then patching and filling cracks and imperfections as needed/desired, then cleaning up patch work by grinding with metal or ceramic bonded diamonds, then honing the surface using ceramic or hybrid bonded diamonds, application of a lithium silicate or calcium silicate (or a combination of the two) densifier to the substrate and allow to cure, then the polishing phase begins using resin bonded diamonds, lastly we apply an added layer stain resistor to the substrate and burnish (or not depending on desired look, burnish creates a high gloss effect).  The more durable a floor is to be means the more steps in the process.  Main factors which influence the amount of steps in the process, as well as time to accomplish each step, are influenced by substrate condition, weather conditions, and types of concrete.
