Selecting the right abrasive tools is a critical step in concrete floor grinding and polishing. Choosing the correct bond not only extends the life of your diamond pads and enhances floor gloss but also helps you effectively control costs and increase project profitability.

1. What is a Bond?

The "bond" is the metal matrix that holds the diamond particles in place within the tooling. During the grinding process, the bond gradually wears away, continuously exposing fresh, sharp diamonds to maintain efficient cutting performance.

Golden Rule for Bond Selection:

Hard Floors → Use Soft Bond (Faster wear, continuous diamond exposure, prevents under-polishing)

Soft Floors → Use Hard Bond (Slower wear, prevents over-cutting, extends tool life)

If you are unsure of the floor hardness, we recommend using a Mohs hardness tester or conducting an on-site test grind. If testing is not possible, opting for a medium bond is the safest and most versatile solution.

2. Three Main Bond Types & Their Applications

⚠️ Warning: Using the wrong bond can lead to "glazing" (where the metal bond covers the diamonds, stopping them from cutting) or abnormal wear – both of which waste significant time and money.
