NEODUR Rapid Screed HE 60 rapid

Application

For the production and renovation of quickly usable composite structures with increased abrasion resistance as industrial flooring for the highest loads, e.g. multi-storey car parks, industrial halls, assembly halls, aircraft hangars, workshops, high-bay warehouses and other industrial areas with the highest loads. For indoor and outdoor use.

Sustainable construction

The use of NEODUR HE 60 rapid increases energy and resource efficiency and conserves natural resources. A hard material industrial floor has an enormous durability. The service life of a hard material industrial floor is many times longer than a pure concrete floor or alternative industrial flooring systems. For further information, please contact the responsible KORODUR contact person.

Processing

• Substrate: The load-bearing concrete (at least C 25/30, surface tensile strength ≥ 1.5 N/mm2) must be prepared, e.g. milling and shot blasting. For a force-fit composite, the surface must be crack-free, even, free of loose and crumbly components and ultra-fine mortar enrichments, as well as rough and open-pored. The requirements of DIN 18365 and DIN 18560 apply. The flatness should comply with DIN 18202, Table 3, Line 3. Thoroughly pre-wet load-bearing concrete one day before installation, avoid puddling. Apply the KORODUR HB 5/60 rapid adhesive bridge to the matt damp surface (see data sheet).

• Processing: Mix NEODUR HE 60 rapid with the specified amount of water for approx. 2 - 3 minutes, depending on the type of processing, until a buildable consistency is reached, apply fresh to the still moist adhesive bridge, peel off in alignment and rub off in a timely manner using a plate smoothing machine to close the pores and smooth according to the required surface structure (leaf troweling machine).

Aftertreatment

Different temperatures influence the solidification or hardening process. NEODUR HE 60 rapid must be protected from drying out too quickly in accordance with DIN EN 13670 / DIN 1045-3. For post-treatment of the NEODUR hard coating, we recommend the products KOROMINERAL CURE or KOROTEX (see data sheets). If subsequent surface treatment, coating or markings are planned, the post-treatment should only be carried out with film.

Joints

The joint grid must be specified by the planner. All joints in the hardened load-bearing concrete are to be taken over in the hard material layer. The hard screed must be separated from rising components (walls, columns, etc.).
