Common issues and queries you can face
Microorganisms
They can colonize both mineral renders and organic coatings.
Wind and humidity
With wind and humidity, microorganisms and pollen eventually settle on facades and form biological soiling.
Low sun exposure
Microorganisms develop more easily on facades with low sun exposure.
