We have developed a long-lasting, environmentally friendly product for the remediation and protection of biologically degraded plasters on insulated façades. This zinc-based solution responds to growing demand for non-toxic, regulation-compliant treatments and has already reached the stage of industrial licensing.

Sustainable Solution for Biologically Damaged Facades
Biological degradation of building façades—caused by algae, fungi, or other organisms—has become a growing concern, especially on insulated buildings. Traditional chemical-based treatments are often short-lived or environmentally hazardous. In response, our team developed an ecological inorganic formulation based on zinc compounds, which offers long-term protection while meeting strict environmental and safety criteria.
Innovative Material Based on Inorganic Chemistry
The core of the product is a non-toxic, waterborne zinc-based solution that acts both remedially and preventively. Its formulation allows for:
• effective suppression of biological growth (algae, fungi, etc.),
• prolonged activity over 6–8 years,
• safe application without harmful emissions or waste generation.
The preparation process is also eco-friendly, relying on inorganic precursors and optimized for low environmental impact.
Application and Certification
The product has been tested in real-life conditions on multiple types of façade plasters and has demonstrated:
- strong adhesion and penetration,
- effective action against visible and underlying biotic growth,
- long-term stability and resistance
to leaching.
The material has been certified by the Czech Technical University in Prague, confirming its performance and safety for building applications. Following successful trials, the licensing was granted to Malpex Ltd., a Czech producer of façade treatments.
Market Relevance and Impact
The development comes at a crucial time: new European Union regulations are restricting the use of conventional biocidal treatments in the building sector. Our formulation provides a compliant alternative, bridging scientific innovation with practical construction needs. This is a strong example of applied inorganic chemistry meeting real-world ecological challenges—resulting in a commercially viable, regulation-ready, and environmentally sustainable product for the construction industry.
