Dirt runs off facades with the rain.
The leaves of the lotus plant are immaculately clean after every rainfall. This is because dirt and microorganisms are unable to obtain a hold on the microstructured,
non-wettable surfaces of the leaves. Dirt particles, algae and fungal spores do not become firmly attached to the leaves, merely lying loosely on the surfaces. Rain simply washes the particles
away. Scientists have managed to apply this natural protective effect to an facade paint.
A team of scientists under Prof. Dr. Wilhelm Barthlott at the University of Bonn discovered the so-called Lotus-Effect® by learning from nature's model. They observed that the leaves of the lotus plant are always clean after it has rained. This is due to the microstructured, extremely water-repellent leaf surface. Many research laboratories have since sought to utilise this effect. Manufacturers of car paints, textile fibres or sanitary ceramics seek solutions for their fields of application. The "StoLotusan Color" facade paint marked the first successful practical application of the Lotus Effect. For a number of years now, many home owners have been benefiting from dry facades which retain their attractive appearance for a longer period. About 40 million square metres of facade surfacing has since been coated with the facade paint featuring the Lotus Effect.
