Concrete polishing is a specialized technique that transforms raw concrete floors into a smooth, durable, and visually appealing surface, with gloss levels ranging from matte to high-gloss mirror finishes. Used in residential, commercial, and industrial projects, polished concrete is now extremely popular in Montreal, Laval, Longueuil, the North Shore, and the South Shore.
In this guide, we provide a clear overview of the concrete polishing process, the methods used, and the key steps required to achieve professional-quality results.
Concrete polishing is a process comparable to sanding wood. Specialized machines, known as planetary grinders, are equipped with diamond abrasive tools that gradually grind the concrete surface to achieve the desired level of smoothness and shine.
The process begins with coarse-grit diamonds and progresses to increasingly finer diamond grits. The finer the grit, the smoother and shinier the surface becomes. The final finish can range from satin to semi-gloss or high-gloss, depending on project requirements.
There are two main methods for polishing concrete floors: dry polishing and wet polishing.
Dry polishing is currently the most widely used method. It is faster, cleaner, and more environmentally friendly. Modern equipment is connected to high-performance dust extraction systems, allowing work to be completed without water and with minimal debris.
Wet polishing uses water to cool the diamond abrasives and reduce dust. While it can extend tool life, it generates liquid slurry that must be collected and disposed of properly, increasing cleanup time and overall costs.
Concrete polishing is a multi-stage process that requires specialized equipment and professional expertise. It typically begins with the removal of existing coatings and the repair of cracks and joints using appropriate materials.
Initial grinding is performed using coarse diamond grits (30 or 40), followed by intermediate passes with finer grits (80 to 150) to level the surface and expose aggregates according to the desired finish.
A chemical densifier is then applied to harden and strengthen the concrete. Polishing continues using resin-bond diamonds (100 to 800 grit), and finishes with 1500 or 3000 grit diamonds to achieve a high-gloss finish.
Depending on floor usage, a protective or stain-resistant treatment may be applied to simplify maintenance and extend surface durability.
Every concrete polishing project presents unique conditions, including concrete type, surface condition, desired gloss level, and floor usage. Incorrect tool selection or skipped steps can compromise both durability and aesthetics.
