THE FINAL TOUCH: HOW TO POLISH CONCRETE

We explore how to polish concrete and create a lasting finish in varying degrees of smoothness.

One the most intriguing aspects of concrete is its finish – it can be rough and raw or smooth and polished. When it comes to polished concrete, the results can differ depending on the level of polishing.

The process of polishing concrete is not dissimilar from sanding wood – diamond-impregnated disks that vary in fineness are used to progressively grind down the surface of the concrete to the desired level of shine and smoothness.

When preparing to polish concrete it is important to prepare the surface by removing any existing coatings using the correct tools such as a 16 to 20-grit diamond abrasive.

For larger pieces or sections of concrete, industrial machinery can be used to create a sleek finish. Disks of varying grits may be used in order to achieve the desired result. When a high polish finish is required, a grit of 1500 or finer is required in order to achieve a mirror-like shine.

Polished Concrete

For smaller pieces, technology has stepped up in the form of hand polishing pads. Similar to sand paper, the pads vary in fineness and are ideal for working on smaller pieces. For designer, artists and visionaries taking part in the PPC Imaginarium Awards, these are recommended tools.

By using diamond polishing pads, varying degrees of smoothness can be incorporated into pieces. Imagine a design that starts mirror sleek at the top, and slowly tapers into a rougher finish at the bottom, effectively showing the gradient of polishes available for concrete.

Concrete is not only malleable in its shape, but also in its final finish. This is why it is such an exciting medium to create with as the possibilities of what we can do with concrete have only just begun to surface...
