When your next concrete polishing job can benefit from a wet polishing method, consider the CRMX 3-Step Polishing System.

Advantages of Wet vs. Dry Polishing Processes

The water used to cool diamond abrasives in a wet polishing process:

  • CRMX Concrete Polishing SystemEliminates grinding dust
  • Reduces friction
  • Lubricates the polishing abrasives, extending their life

Machines used in the dry polishing process:

  • Require no water to cool the diamond abrasives
  • Eliminate virtually all of the mess usually associated with a wet polishing process that a crew must clean up, which slows productivity

During concrete polishing jobs, contractors can opt to use both processes for different stages of grinding. Dry polishing can be used for the initial phase, to remove the most concrete. To achieve the smoother stages of polishing, crews can shift to the wet polishing process.

Advantages of the CRMX 3-Step Polishing System

When this system process is followed concisely, GMI guarantees the results are “perfect” every time:

  • Works the same on all concrete floors regardless of hardness
  • Used for every stage of concrete polishing
  • Virtually dustless polishing process
  • Eliminates the need for topical polish guards
  • Reduces tooling inventory
  • Simplifies diamond selection process
  • Reduces labor costs by as much as 45%
The CRMX Polishing Process

Following proper steps and procedure is critical to achieving perfectly polished concrete every time. Each step includes instructions for tooling and chemicals. Here is how the process works:
Floor Preparation – move directly to Step 1 after floor prep unless a PCD tool is used. Then follow floor prep with the appropriate metal bond tool to mitigate the scratches before proceeding to Step 1.
Tooling Component: The 10-Segment Canvas “Setting” Tool is designed to operate in conjunction with the CRMX™ Surface Refining Agent, removing the most difficult scratches on the hardest concrete surfaces. In one fast step, reduces labor and additional tooling costs because it can follow 6-, 16-, 20-, 30-, 50-, 80- or 100-grit metal bonds
Chemical Component: Uses with tools in both Step 1 and Step 2, the CRMX Surface Refining Agent helps in removing scratches quickly, eliminating the need for lengthy grinding steps to achieve high levels of clarity.
Tooling Component: Made from natural earth materials, the 5-Segment Canvas “Refinement” Tool will not transfer spent resins in the concrete surface that cause contaminated finishes and provides a scratch-free surface that can be sealed as is. For a higher refinement, continue to Step 3.
Chemical Component: The CRMX Densifier hardens and increases density in one, ready-to-use formula, dust-proofing concrete with nano-sized particles. Once properly applied, the densifier significantly improves the durability of the surface, resisting moisture and topical water spills. The densified floor has to be completely dry before proceeding with the polishing tool.
Tooling Component: Developed to produce the cleanest finishes in the industry, the 3-inch Canvas “Polishing” Tool is constructed with the highest grade epoxy resins available, producing average gloss ratings of 70 and frequencies in the single digits.
Chemical Component: The CRMX Acid Blocker is formulated to perform in high pH environments and high traffic settings such as retail groceries, commercial facilities and industrial floors, rendering a high performance, ultra-hard, water tight, dust-repellant surface that is resistant to chemicals and acid staining. It provides a 60% increase in light reflectivity from untreated concrete surfaces without decreasing the coefficient of friction on surfaces. Burnish with a non-diamond high speed burnishing pad after the chemical has completely dried.
