Know what Concrete Finish you are getting!

The greatest benefit of a polished concrete floor is the cost factor.

If floors are polished correctly, it represents outstanding value for the finish and ongoing maintenance of the floor.

The problem with Polished Concrete floors is knowing if what you expect, is what you are getting!

* In the absence of an industry standard, many contractors, and suppliers of products within the industry have presented their process and products as a "standard".

This has led to multiple 'Standards' that do not offer accountability.
The lack of accountability allows polished finishes to fall short of the quality that should be achieved. In turn, this has affected the credibility of polished concrete floors internationally.



How can you Measure a Polished Concrete Finish?

To address the concerns around the Lack of Credibility & Accountability, the American Concrete Sawing & Drilling Association (CSDA) developed the first Industry Standard, the ST-115.

The standard uses a Roughness Average (Ra) meter to physically measure the texture of the concrete surface microscopically with a Diamond tipped stylus and gives the data as a number that can be referenced to a table that gives the surface measured a grade.

Now, a level of finish is achieved by specifying the desired Ra range, holding the contractor to an agreed standard. This means regardless of who is doing the  polishing or the condition of the concrete surface, the same floor finish is achieved every time

Taking the Measure of Polished Concrete
  • "The CSDA believes that gloss levels shouldn't be a matter of opinion, but should be based on measurable, quantifiable standards."

    -Christopher Bennett, Husqvarna Construction Products

  • "To date, ST-115 is the only tool I know of that offers the design community quantifiable, scientific, and perhaps most importantly, repeatable results."

    -Christopher Bennett, Husqvarna Construction Products

  • "While the term "grit" is a common and even useful reference to describe gloss levels, it has not been able to precisely define the polish level on any proven, acceptable, repeatable scale."

    -Christopher Bennett, Husqvarna Construction Products

  • "Measure what is measurable, and make measurable which is not so."

Instruments for Measuring Floor Surfaces
Are you getting what you paid for? And is it compliant to NZ slippage standards?

Light meters or distinction of image (DOI) meters are tools that tell one side of the story, but they have limitations. A light meter can tell you how much light a floor reflects, but it can’t tell you why that light is being reflected.
Likewise, A DOI meter can tell you how sharply an image is reflected in the floor. But again, it can’t tell you if the floor is actually polished to spec.
These meters are not reading the refined texture of a concrete floor, but the surface of the clear-coat epoxy or topical sealer placed over a floor. A Glossy Sealer can be put over a surface in order to reach DOI numbers but still wont indicate whether the surface of the substrate itself has been refined as specified.

An Ra Meter measures the surface of a refined substrate Prior to any sealer going down. This gives evidence to the client & reassurance to the contractor that the agreed specification has been met and the seal is not used to deceive the eye.
Once a Sealer has gone onto the floor, an Ra Meter is no longer reading the substrate surface texture, but that of the Sealer.

A Slip Meter (tribometer) provides a simple method of testing a floors static Co-Effiency for compliance against slip hazards.
A slip meter whilst can be used wet or dry is often used to confirm a finished floor surface is slip resistant when it's wet.
New Zealand slip compliance value is defined as having a surface with a Co-Effient of Friction (CoF) reading greater than 0.4 or a Slip Resistant Value (SRV) of 39 or greater
