System description

The coating system K3 complies with all requirements in accordance with the TR maintenance directive or RiLi SIB (DAfStb) based on OS 11b for the production of tested car park coatings. The system offers increased dynamic capability for crack-bridging on surfaces that are accessible to foot and vehicle traffic, but must not be used on weather-exposed surfaces. As a result from production processes, the system’s layer thickness is at > 4.0 mm, plus the surcharge for roughness depth.

In indoor areas, the system is particularly suitable as car park coating with an adjusted slip-resistance grade of R11. As surface protection system, it is impermeable to liquids, thus protecting the underlying building structure.

Alternative systems: System K1 as OS 8 version in the interior, System K2 as OS 11a version for use in outdoor areas exposed to the elements.


  • slip-resistant in R11
