K28A Heavy-Duty Diamond Aggregate Dry-Shake Floor Hardener

K28A is a high-strength, dry-shake mineral aggregate floor hardener formulated with high-hardness metallic aggregates, selected quartz sand, special cement and functional additives. It is evenly applied to freshly placed concrete during the initial setting stage and mechanically trowelled to form a dense, durable and fully integrated wear-resistant surface.

The finished floor provides excellent resistance to abrasion, impact, heavy loads and surface dusting. It is designed to withstand frequent traffic from forklifts, industrial equipment and heavy vehicles while significantly extending the service life of concrete floors. K28A can be applied together with newly poured concrete, offering efficient installation, easy maintenance and a range of optional colours.
