NEODUR Hard Screed HE 65 Plus

Application

For the production of heavy-duty industrial floors, 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.

• Waterproof, suitable for wet rooms
• Non-slip, Non-slip,
• Anti-slip Frost and de-icing salt Resistant
• Electrostatic Non-rechargeable
• Chloride-free
• Physiologically and ecologically harmless
• Consistent
• quality through quality assurance in accordance with DIN EN 13813

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 NEODUR HE 65 Plus water-diluted surface to the matt damp surface in a slurry-proof consistency with a hard street broom as an adhesive primer.

• Application: Mix NEODUR HE 65 Plus 65 with the specified amount of water for approx. 3 minutes and draw off onto the pre-slurried substrate "fresh on fresh" via gauges (round bars) using an aluminium straightener or vibrating plank 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 smoothing machine).

Aftertreatment

Different temperatures influence the solidification or hardening process. NEODUR HE 65 Plus 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

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