LEVL Top WL — mortar topping for restoring old concrete floors
High-strength cement mix laid over old concrete indoors and outdoors; compressive strength at least 70 MPa, flexural strength 8 MPa.

Laying of PoliCem polyurethane-cement floors starts with priming with LEVL PoliCem PU 05. The three-component material based on modified polyurethane, cement and aggregate seals concrete pores; it is applied with a flat trowel in two coats, filled with quartz sand. Substrate moisture must be no more than 6 % by weight, and the working temperature from +10 to +30 °C. Systems on this primer are used at food and pharmaceutical plants, in livestock farming, the chemical industry, workshops and warehouses.
