Mohs 7+Extra Soft#80Reduces glazing on very hard aggregate.

Coating removal

PCD or aggressive metal tooling first, then metal bond cleanup.

Ask for a before/after scratch photo from the test pass.

Grinding

Use the bond table by floor hardness and keep passes even.

Move to the next grit only after scratches are consistent.

Polishing prep

Avoid skipping transition grits before resin pads.

Confirm the floor is flat before moving into higher grits.

Surface prep

Prioritize stable scratch profile and predictable tool life.

Choose a conservative first set when hardness is unknown.

QC Proof to Request

Request segment height photos, Redi-Lock fit check, and packing video for bulk sets.

  • Segment height measurement.
  • Bond and grit label photo.
  • Quantity and packing count.
  • Carton mark and shipment reference.
