Polished Concrete Services
Concrete Floor Polishing
Polished concrete is a multi-step process where a concrete floor is mechanically ground to a smooth, flat, consistent surface and polished with bonded abrasives in order to cut a concrete floor's surface. It is then refined with each cut in order to achieve a specified level of appearance from minimal, medium to full exposure finish.

Grind and Seal Concrete Services
This system is not considered to be polished concrete as there is very little physical refinement of the concrete slab. However, it does provide a similar look to polished concrete and may be appropriate and recommended for warehouse, garage, driveways, alfresco.

Our Polish Concrete Process
A diamond polished concrete floor is very a comprehensive process, due to the fact that there are at least six to twelve steps of actual grinding involved. The general rule is to start the initial grinding with a coarse 30/60-grit diamond and finish with an 800, 1500- or 3000-grit diamond, depending on the exposure level of aggregate and gloss level required. These diamonds are impregnated inside a metal or resin-bonded segment. Typically the diamonds' grit size will double once the first grind has been carried out. The polishing process begins with a 50-grit diamond resin pad instead of a metal segment. When using the resin pads the steps may be 100, then 200, 400, 800, 1500 and finally 3000 grit. Throughout the process, a densifier/hardener is used to harden the concrete surface, which allows the concrete to be polished. A number of densifiers/ hardeners can be used; these consist of lithium or potassium. In some cases, a grouting chemical is also used to fill in any holes, cracks or imperfections that were exposed from the initial coarse grinding step. The concrete can be also finished with a natural-look impregnating polish guard, which penetrates 2–5mm inside the pores of the concrete to prevent any deep staining from oils and spills. It is also breathable and not a sealer (as a sealer actually totally seals the concrete and does not allow vapor transmission).
Diamond-polished concrete floor process can have different exposure level and gloss level such as.
- Salt & Pepper Concrete Exposureminimal/medium and full Concrete exposure
- Gloss level Concrete Exposure
- Satin, semi-gloss, gloss, high gloss polished concrete exposure
