When you ask BestFinish to paint your home's exterior, this is the coating we recommend most. Inspired by the fog-basking beetle of the Namib desert and certified by the Fraunhofer Institute for the fastest drying time of any facade paint tested, Dryonic® keeps facades dry, beautiful, and free from algae and fungi — naturally.
The Namib desert sees barely 12mm of rain a year. Yet the fog-basking beetle thrives there, harvesting drinking water out of thin air. Its secret: a shell covered in countless microscopic bumps. Hydrophilic tips condense fog into water; hydrophobic depressions channel it away in seconds.
Sto's research team studied that surface, then transferred the principle into a facade paint. The result is Dryonic® — a coating with the same micro-textured architecture, working the same way. Where ordinary paints stay damp for hours after rain, dew or fog, Dryonic® dries in record time.
That single difference — speed of drying — is what keeps a facade radiant for years instead of fading and greening.

A patented microtexture, baked into the paint's binder architecture, gives the surface its self-managing properties.
The microtexture turns the facade into a directing surface. Rain, fog and dew bead, run off and evaporate before they can soak in.
Without prolonged surface moisture, the conditions micro-organisms need to colonise simply don't exist. Protection is structural, not chemical.
Less moisture means less weathering, less fading, less greening. The colour you paint today is the colour your neighbours see in five years.
The Fraunhofer Institute for Structural Durability and System Reliability (LBF) tested five leading facade paints side-by-side, measuring how quickly each one shed water and dried after exposure. Dryonic® came out fastest in every measured condition.
That is not a marketing claim from Sto — it is an independent result from one of Europe's most-cited applied-research institutes, and it is repeatable across colour shade, substrate and weather.

algae & fungi protection comes from physical surface texture — not biocides leaching into the soil
performance is independent of shade, substrate or prevailing weather conditions
A paint job is only as good as the coating that goes on. Cheaper facade paints might look identical the day they're applied — but the test is what your home looks like in three winters' time. We use Dryonic® because we want our work to be the work that still looks fresh five years on.
BestFinish is trained and approved by Sto to apply their iQ-Technology coatings to specification.
Stucco, render, brick or pebbledash — Dryonic® performs across substrates we work on every week.
Heavy dew, drizzle and damp days are exactly the conditions Dryonic® is engineered to survive without algae bloom.
Higher up-front cost, lower lifetime cost. A facade you don't have to repaint, jet-wash or treat every other year.
