Concrete Floor Grinding

Concrete Floor Grinding and Polishing

Concrete floor grinding doesn’t sound like the most glamorous of jobs; that’s why the DirectStone team tend to use “We work with diamonds’ as our party opener! And of course, it’s true. Our HTC Superfloor™ grinding machines use diamond tools to grind back the surface of concrete floors to expose the unique patterning of the aggregate beneath, in preparation for concrete polishing.

Diamond Floor Grinding

As specialist providers of polished concrete flooring, the DirectStone team is also skilled in concrete floor grinding, or diamond floor grinding. This is the process of grinding back the surface paste of concrete to reveal the aggregate beneath, in preparation for polishing. It also has a number of commercial and industrial applications:

  • Removing legacy flooring or dry adhesives.
  • The removal of oil or dirt deposits.
  • Floor levelling.
  • Reprofiling older concrete slabs.

Residential Concrete Floor Grinding and Polishing

DirectStone floor specialists transform and industrial material into elegant polished concrete flooring in rather the same way that a wood carver transforms timber into objects of beauty. We begin by grinding back the ‘surface paste’ of the slab to reveal the aggregate patterning below. Once the desired aggregate exposure is revealed, the concrete is hardened with a densifier and sealed to enhance stain resistance.

When the initial grinding is complete, the polishing phase begins. We use diamond studded pads to achieve this, applying ever-finer grits until we achieve the required sheen. Our flooring team has the experience to know exactly when to switch from one grit size to the next, simply by observing the condition of the polished surface and the rate of surface removal.

Polished Concrete Floor Finishes

Every polished concrete floor is unique, not only because of the aggregate patterning and colouring, but also because of the finish chosen. There’s a range of options to select from:

  • Bronze Finish. This is the only finish that doesn’t begin with grinding back the surface paste. Instead the top layer of the surface paste is polished to a deep, mirror-like sheen.
  • Silver Finish. We grind deep into the concrete until the ballast is exposed. The surface is then left unpolished for an elegant matte surface finish.
  • Gold Finish. This is a gloss finish which is achieved by grinding back the surface paste and then polishing the surface with the HTC Twister™ to produce a tough, durable finish.
  • Platinum Finish. The high gloss effect which is achieved with platinum, requires the most grinding and polishing stages. The result is an unbeatably durable, shimmering floor.

Sustainable Concrete Flooring

In many cases concrete floor polishing doesn’t require the addition of new materials. Most of the residential work we do is grinding and polishing existing concrete floors that may have been hidden for years beneath existing floor coverings. In this case creating a polished concrete floor is about revealing and recycling, rather than adding.

Maintaining Your Polished Floor

DirectStone clients are always delighted to hear that polished concrete flooring requires on light touch maintenanceIt’s important to keep the surface free from dust and grit, as this can create microscopic scratches that dull the sheen over time. For long-lasting shine, simply sweep your concrete flooring regularly, and mop with a light detergent.
