NEODUR Floor Leveling Compound Level AU

Application

For the levelling of uneven floors in a composite on cementitious substrates as a floor levelling compound before installation, e.g. of ceramic tiles and slabs, marble and natural stone slabs, PVC coverings, carpets in residential and industrial buildings and equally suitable for NEODUR Level industrial flooring (see data sheet). NEODUR Level AU must always be occupied.

Sustainable construction

The use of NEODUR Level AU reduces the CO2 footprint, increases energy and resource efficiency and conserves natural resources. The production of the binder requires 30% less CO2 emissions than conventional Portland cement. For further information, please contact the responsible KORODUR contact person.

Properties

• Easy to mix
• Highly flowable
• Pumpable
• Faster hardening
• Early ready for paving
Low
• stress

Processing

• Substrate: Prepare cement substrate by milling and/or shot blasting before laying. Existing cracks, breakouts and damaged joints must be professionally repaired. The substrate must be load-bearing, firm, clean, dry, crack-free and free of loose parts, oils, greases or other adhesion-reducing impurities.

Surface tensile strength:

• without driving stress ≥ 1.0 N/mm2
• with driving stress and/or outdoors ≥ 1.5 N/mm2

requirements of DIN 18365 and DIN 18560 apply. Apply KORODUR PC primer to the prepared substrate, for processing see KORODUR PC data sheet.

• Processing: Place NEODUR Level AU in a clean, suitable container (e.g. KORODUR 30-litre mixing bucket) and mix with approx. 4.0 l of water using a suitable mixing whisk at least 650 rpm or compulsory mixer (e.g. Collmix LevMix or Hippo mixer) for approx. 3 - 5 minutes until lump-free and homogeneous. Commercially available screw pumps (e.g. Duo-Mix 2000 or inoCOMP Cabrio) and continuously operating mixing pumps (spread dimension according to DIN EN 12706 = 12 - 13 mm with cylinder/measuring tube with d = 32 mm and h = 51 mm) are suitable for machine processing. Do not use a mixing technique that introduces large amounts of air. In order to apply the material evenly, the use of a suitable squeegee is recommended. To remove air pockets, the surface that is still flowable must be treated with a suitable spiked roller. Mixed NEODUR Level AU should be applied within 30 minutes.

Aftertreatment

Different temperatures influence the solidification or hardening process. Under normal conditions at 20 °C, no post-treatment is required. For outdoor installations, we recommend applying a fine water mist to the freshly set surface as soon as possible without damaging the surface. The aftercare with water should be continued for at least 1 hour. Excessively dry, windy, hot or sunny conditions should be avoided.

Joints

All joints in the substrate are to be taken over in the NEODUR Level AU levelling compound. NEODUR Level AU must be separated from rising components (walls, columns, etc.).
