Meanings of  Sand-Retaining Grinding and Polishing of Emery (Floor hardener) Floors :

1 Emery Floor

Refers to Emery Wear-Resistant Floor, a high-strength, abrasion-resistant surface formed by broadcasting emery (carborundum) aggregate (Floor hardener) onto fresh or hardened concrete, then troweling and compacting it. Commonly used in factories, warehouses, parking lots, etc.
2 Sand-Retaining

Means retaining the emery particles on the surface layer to prevent delamination or loss, ensuring long-term abrasion resistance and slip resistance.“Sand retention” is a key indicator of construction quality.
3 Grinding/Polishing

Involves mechanical grinding using diamond grinding pads or resin polishing discs on cured emery floors to:
◦ Remove surface laitance and burrs
◦ Expose and trim emery particles
◦ Improve flatness, gloss, and dust-proof sealing
◦ Achieve a mirror finish or matte anti-slip surface

Overall Meaning:
“Sand-Retaining Grinding and Polishing” is a precision finishing process performed on emery wear-resistant floors using professional grinding equipment and diamond tools. Through multi-stage grinding, it exposes and secures emery particles while enhancing flatness, gloss, and durability.

Typical Sand-Retaining Grinding Process:
1 Coarse Grinding (30#–50#): Remove laitance, initially expose aggregates
2 Medium Grinding (100#–200#): Trim particles, achieve >90% sand retention
3 Fine Grinding (300#–800#): Improve flatness and gloss
4 Polishing (1000#–3000#): Optional, for mirror-like finish
5 Sealing/Hardener Application: Enhance sand retention and dust-proofing
