  • Elastic and crack-bridging
  • Abrasion-resistant and easy to clean
  • Simple dosing at the specified mixing ratio
  • Slip resistance possible by scattering in quartz sand

Areas of application

  • Balconies, access walkways and terraces outdoors
  • Priming and levelling under Sikafloor systems
  • Indoors and outdoors on concrete and cement screed

Technical details and application

Sikafloor-410 is a 2K preparation. The substrate must be clean, load-bearing, dry and free of greases, oils and separating substances. Do not use on ceramic coverings, as trapped moisture can lead to detachment and discolouration. Consumption about 0.15 kg/m²; on floors with full-surface chip scattering, two passes are recommended. For a slip-resistant surface, scatter in 10 to 30 g of quartz sand (0.1 to 0.3 mm) per litre.
