LEVL Top Cor corundum topping reaches at least 80 MPa in compression after 28 days (slightly less than Top Corund), with abrasion up to 0.35 g/cm². The mix of cement with graded corundum and quartz sand is broadcast dry onto fresh concrete of at least M300, floated by machine, and then LEVL Cure 100 is applied. The coating is designed for very significant mechanical loads in workshops, warehouses, car parks and on ramps. Besides the natural grey version, green, red, light grey and dark grey ones are produced.
