Munich Airport – Wall coating for sensitive service areas
Seamless hygiene and lasting durability.
Assignment and requirements
In the new Technical Service Building at Munich Airport, approximately 600 m² of wall surface in a hygienically sensitive area needed to be coated. Containers from aircraft sanitary technology are collected, cleaned, and disinfected there.
A robust, liquid-tight, and chemical-resistant wall coating was required, which is permanently disinfectable and withstands intensive cleaning processes.
Particularities and challenges
To exclude hygienic weak points, the wall coating had to be completely seamless. At the same time, the large wall area and tight timeframe placed high demands on uniform and efficient processing.
The surface also had to permanently withstand daily chemical and mechanical stresses and enable reliable cleaning and disinfection.
The solution
With the reinforced epoxy resin wall coating system N1 KLB INDUSTRIAL WALL EP, a homogeneous, seamless, and slightly structured surface was created. After priming with KLB-SYSTEM EPOXID EP 50 and an optional filling of blowholes, the base coating was applied with KLB-SYSTEM EPOXID EP 699 S. The KLB Reinforcement Fleece VA 125 × 300 was embedded into the fresh layer, rolled, and then over-sealed again with EP 699 S.
Due to the area size, EP 699 S was applied using a Graco airless machine in a spray process. This allowed for a uniform material application and significantly reduced the execution time.
The result is a robust, liquid-tight, cleanable, and disinfectable wall coating that permanently meets the high chemical and hygienic requirements of the sensitive service area.
