System description

The coating system K2 complies with all requirements in accordance with the TR maintenance directive or RiLi SIB (DAfStb) based on OS 11a 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, as well as on open parking decks. As a result from production processes, the system’s layer thickness is at > 4.5 mm, plus the surcharge for roughness depth.

In indoor and outdoor areas, the system is suitable as coating for parking areas or park decks with an adjusted slip-resistance. As surface protection system, it is chemically resistant and impermeable to liquids, thus protecting the underlying building structure.

Alternative systems: System K1 as OS 8 version in the interior, System K3 as OS 11b version with higher crack-bridging at up to -20 °C / -4 °F.
