LEVL Top Corund Premium ST — quartz-corundum topping with low abrasion

Toppings

LEVL Top Corund Premium ST has one of the lowest abrasion values in the LEVL range: no more than 0.15 g/cm². The mix of Portland cement with quartz and corundum aggregate is applied dry onto fresh concrete, floated by machine and coated with LEVL Cure 100. Compressive strength at 28 days is at least 90 MPa; service from −40 to +60 °C, short-term up to +100 °C. The material is intended for workshops, warehouses, car parks and ramps; work is carried out at temperatures of at least +5 °C.
