In the Kö8 shopping center in Köngen am Neckar, the new "CurryBox" snack bar is now providing shoppers with currywurst, burgers etc. As spills are part of the fast food business, the stand area is designed to be hard-wearing and easy to clean, without neglecting design quality. Shell limestone-colored large formats with an easy-to-clean proClean surface were chosen. The deep hydrophobization of the concrete largely prevents the penetration of dirty water and the surfaces are easier to clean. In addition, the attractive appearance of the visible surfaces is completely retained.
