Types of finishes for Polished Concrete Flooring

There are essentially 3 types of finishes produced when looking to polish concrete flooring.  The easiest way to understand it is to think of finishes in terms of more work put into finishing the longer lasting and more resilient it will be.  See below for types of finishes and to learn more about polished concrete flooring.

 

Industrial Finish

Generally working up to about a 400-800 grit finish, the Industrial Finish provides a smooth finish with minimal reflection and little to no aggregate showing.  Perfect for industrial or high traffic commercial use.

  • Lower Cost Option

  • Low Cost Maintenance

  • Slip Resistant

  • Spill Resistant

  • Eco-Option/LEED Certified

  • Highly Durable

 

Commercial Finish

Generally working up to about an 1500 grit finish, the Commercial Finish provides a smooth finish with a more mirror-like reflection and often scattered small aggregate showing.  Perfect for industrial, commercial, and residential.

  • Low Lifetime Cost

  • Easy Clean Up & Maintenance

  • Slip & Spill Resistant

  • Eco-Option/LEED Certified

  • Highly Durable

  • Abrasion Resistant

 

Premium Finish

Generally working up to about a 3000 grit finish, the Premium Finish provides a mirror-like reflection.  The Terrazzo look is often exposed aggregate with a premium finish. This is a showroom finish where design qualities and reflectivity are a priority.

  • Lowest Lifetime Cost

  • Easy Clean Up & Maintenance

  • Highly Spill Resistant

  • Eco-Option/LEED Certified

  • Highly Durable

  • High Abrasion Resistance

Types of Aggregate Exposure Levels

With polished concrete, there are essentially 4 aggregate exposure levels. As the concrete is profiled deeper, more aggregate is exposed, creating different looks.  Each desired look depends on concrete.

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.
