Self Cleaning Walls

About the Lotus-Effect®

The Lotus-Effect® phenomenon was discovered by German botanist Prof. Dr. Wilhelm Barthlott, and developed by Sto for use in facade coatings.

A lotus leaf sheds water and dirt effortlessly in order to stay clean. This natural phenomenon is caused by a unique microstructure that prevents water from gripping the surface. Using biomimicry, Sto manufactured StoLotusan Color paint with a near identical microstructure to that found on the lotus leaf.

Features & Benefits of StoLotusan

A unique microstructure

The secret to StoLotusan Color is a unique, patented surface structure at the microscopic level, similar to the microstructure discovered on the leaf of the lotus plant. Combined with carefully selected materials, this prevents water and dirt from clinging to the surface.

Keeps the facade pristine for longer

Loose dirt will still accumulate on the surface during dry periods, but as soon as it rains then the dirt will be washed away, leaving a clean and dry facade.

The best natural protection from algae and fungus

Unsightly blue-green algae requires water and dirt to thrive and spread. By removing these two factors from the facade, StoLotusan Color provides the best natural defence against this common problem.

• High and sustainable water repellence;
• Self-cleaning effect on façade surfaces;
• High film persistence on façade surfaces;
• High resistance to effects of smoke, UV rays and other atmospheric factors;
• Long-term resistance to algae and mildew;
• Suitable for tall buildings, which have no or minimum projecting roofs;
• Suitable for environments, where pollution is present due to traffic and industry (city centres, industrial zones);
• Available in granulations of 1.5 / 2.0 mm;
• Long open periods for application to façade surfaces;
• Easy application.
