One of the key challenges associated with traditional buildings constructed from vernacular materials is their response to climatic agents and microorganisms. These present a significant challenge also for the surface of constructions based on unbaked clay elements. This paper presents the possibility of creating plasters based on clay, lime and other additives, their behaviour in response to mould growth, and the potential for coating treatments to enhance their resistance to the harmful action of microorganisms. The antifungal treatment was conducted with the objective of exploring the potential for recycling expired non-food household and medical products. The experimental results indicated the initial development of colonies of Penicillium notatum and Aspergillus niger and subsequently demonstrated the potential for enhancing resistance to mould action through pellicular treatment and/or surface impregnation. It can therefore be concluded that not only is it possible to create clay-based plasters with enhanced performance, but also that this represents an original contribution to the implementation of the concept of the circular economy.
