Lime-Based Finishes and Their Resistance to Algae and Mold Growth

Limewash and German Smear, both derived from lime-heavy materials, offer natural resistance to algae and mold through their alkaline properties and breathability. These finishes create environments inhospitable to microbial growth while allowing moisture to escape, reducing the conditions that foster such issues. Understanding their scientific mechanisms and the role of breathable waterproofing can inform choices in architectural applications.
