StoColor® Dryonic® 

Intelligent paint for dry facades.

A building‘s aesthetic depends on more than the colors, materials and original design, it requires high performing materials that help keep facades beautiful. StoColor® Dryonic®, part of Sto‘s iQ TechnologyTM family of coatings, combines supreme performance with intelligent technology – for optimum resistance to weathering and protection against algae and fungi.

We are proud to be an approved applicator of StoColor® Dryonic®       This innovative paint uses     a technology borrowed from nature which allows it to both repel water and channel it away at the same time.


When it comes to facades, aesthetic appeal is what counts. However, achieving a successful facade design is not simply about choosing the right color. Facade coatings are constantly exposed to weather- ing and run the risk of fading or being attacked by unpleasant microorganisms, which means they have to be able to do much more. 



 Is your house suffering from  green algae and mold attack?   

An inspired, natural way of keeping facades vibrant and beautiful.

StoColor® Dryonic® was inspired by the fog basking beetle. It lives in the Namib desert and has adapted to the conditions that prevail there perfectly. For this beetle, constant drought is no problem, as it can turn fog into drinking water.

So what is its secret? Its shell is covered in countless microscopic bumps. Thanks to this unique surface texture, the beetle is able to turn fog into liquid fast: while the hydrophilic tips let the water condense, the hydrophobic depressions in between divert the water away. 

Sto has taken this observation from nature and transferred it into top performing facade paint. The paint's special surface texture helps dew and rain on the facade  dry in record time, depriving algae and fungi of the nutrients they need to grow. This unique, patented, Dryonic® Technology helps provide bright and gleaming facades on virtually any substrate, year in and year out.

High performance coating that dries extremely quickly after rain, fog or dew, protecting against algae or mold growth.

STO have mimicked the shell of the fog-basking beetle to create our Dryonic® Technology. Using an innovative formulation with a clever architecture of binding agent and extender, a microtexture forms on the coating‘s surface. 

The result is an extremely quick drying surface after rain, fog, and dew.             The facade has an environmentally friendly and long-term safeguard against algae and fungal attack.

The Fraunhofer Institute for Structural Durability and System Reliability LBF tested five facade paints with regard to their drying properties. The result: StoColor® Dryonic® excelled with the fastest drying times.

Irrespective of the choice of color shade, the composition of the substrate, or the prevailing weather conditions, StoColor® Dryonic® provides dry, beautiful, and radiant facades that last.

StoColor® Dryonic® Projects & Reviews

“We used the StoColor Dryonic façade paint on our property some years ago and we were absolutely delighted with the results. The building looked excellent when the job was done and it has certainly retained its good looks. The paint really stays clean and white. I’d have no hesitation in choosing StoColor Dryonic for any future repainting.”

Nigel, Haywards Heath

“The StoColor Dryonic façade paint really is a superior product. Our building was painted at the same time as our neighbour’s property. Our decorator, GLR Painters used StoColor Dryonic in white, while the neighbour’s decorator used an exterior white trade paint. 18 months later and our house is gleaming white and theirs is back to a faded cream colour.”

“We’re very proud of the fact that we’re an authorized applicator for StoColor Dryonic façade paint. It’s an incredible, innovative paint that uses techniques found in nature to provide a rugged and reliable surface which both repels any water falling on it and channels it away at the same time. It gives great, long-lasting protection against the growth of algae which can cause staining problems in the future.
