LEVL Top Corund — corundum topping for heavily loaded floors

LEVL Top Corund, a dry mix of cement with graded corundum and quartz sand, is intended for floors under very significant mechanical loads. It is worked into fresh concrete of grade M300 or higher, after which the surface is treated with LEVL Cure 100 curing compound. After 28 days compressive strength reaches 90 MPa, abrasion (wear) does not exceed 0.35 g/cm², and service is permitted from −40 to +60 °C. Colours: natural grey, green, red, light grey and dark grey.
