Kirsten OHG – Floor coating for old buildings and industrial areas

Assignment and requirements

In the historic building of a former military hospital from 1866, the heavily worn out concrete floor needed renovation. The goal was to create a calm and harmonious floor surface that visually integrates with the historic masonry while meeting the functional requirements of modern use.

Particularities and challenges

The heavily stressed concrete showed numerous cracks and spalling, posing a significant dust and safety risk. In some areas, the substrate was so weak that it had to be removed and newly concreted.

Additionally, there were areas in contact with the ground with residual moisture ingress, which can quickly lead to blistering and delamination with conventional coatings. At the same time, a solution was required that preserved the historic character of the building while withstanding heavy loads from machinery and transport equipment.

The solution

The diffusion-open E2 KLB INDUSTRIAL DIFFUSION LOW-VOC EP Standard epoxy system provided the ideal solution for safely coating the moist substrate. After priming, levelling, and coating, the floor was finished with a matt top sealer, creating an easy-to-maintain and chemical-resistant surface.

The result is a durable industrial floor that withstands high point loads, visually complements the historic building, and ensures healthy indoor air quality thanks to the “Indoor Air Comfort Gold” certification.
