Course Description

This presentation addresses the need to implement advancing technology and methods to produce polished concrete coupling a mechanical process with concrete treatments.  

From the introduction of ‘modern densifiers’ in the early 1900’s to the advent of dry abrasive profiling and polishing, the last 100 years have seen advancements in the way we treat the final concrete surface.  

What was proven to have been counter-productive?  

What technology and approach will yield the most consistent results and longest lasting architectural concrete flooring ?

At the conclusion of this presentation you will have a general understanding of what polished concrete is and is not, how it is achieved mechanically, color enhanced and protected by treatments; and finally why specify polished concrete – it is versatile, economical and sustainable.
