Diamond Sand Wear-Resistant Flooring

Product Details

Diamond-hardened wear-resistant flooring is a high-strength surface created by uniformly spreading diamond-hardened aggregate and grinding it into the concrete during its initial setting phase. The aggregate bonds permanently with the concrete substrate, forming an exceptionally durable surface that offers outstanding wear resistance, impact resistance, and dust and sand prevention. Economical and long-lasting, it requires no additional coatings and boasts an extremely long service life. It is widely applicable in industrial workshops, warehouses, logistics centres, car parks, and other locations demanding the highest levels of wear resistance.

Construction Steps

1. Substrate Preparation: Remove debris, loose particles, hollow areas and oil-stained sections before grinding. Roughen smooth surfaces and establish concrete elevation benchmarks.

2. Concrete Placement: Use concrete with strength grade ≥ C25 and slump controlled at 120–140mm. Level using laser screed or screed bar before initial setting, achieving ≤3mm deviation when tested with 2m straightedge.

3. Concrete Bleeding: When concrete compresses under foot by approximately 5mm or 3-4 hours post-pouring, employ a disc trowel to draw out bleed water and eliminate segregation;

4. Abrasive Application: Apply 2/3 of total abrasive aggregate evenly in the first pass. Roughly level with a wooden float to ensure aggregate-concrete bonding. For the second application, scatter the remaining one-third of aggregate vertically. Manually supplement corners and adjust local flatness.

5. Compaction and finishing: After aggregate application, use a disc-equipped trowel machine to grind the surface twice in both directions, eliminating segregation and compacting the aggregate. Before final setting, switch to metal blades and adjust speed and angle to complete 3-4 passes of fine grinding and polishing. Finish corners manually with an iron trowel.

6. Cutting and Curing: Determine cutting timing based on ambient temperature (typically within 24 hours). Within 4-6 hours post-construction, spray specialised oil-based curing compound or cover with damp geotextile, maintaining moisture for 7 days.
