WEBAC® 4290 + WEBAC® 4490: surface protection system for coating traffic areas in car parks and underground car parks

The coating WEBAC® 4490 and the primer WEBAC® 4290 form a surface protection system of class OS 8. This coating system is particularly suited for use in indoor car parks and underground car parks where substrates are exposed to specific loads. These loads include not only mechanical stress caused by vehicle traffic but also rainwater and road salt carried along by vehicles and seasonal changes in temperature. 

WEBAC® 4490 for coating underground car parks

After preparing the substrate to be coated the primer WEBAC® 4290 is applied and scattered with quartz sand. WEBAC® 4490 is then applied as intermediate coat and also scattered with quartz sand. WEBAC® 4490 also serves as topcoat and sealer. Traffic areas in underground car parks and indoor parking decks provided with this coating system are suitable for vehicular traffic and withstand mechanical stress.
