Abstract: Objective. The objective of this study is to evaluate the influence of technological process parameters on the shielding effectiveness of conductive composite coatings, as well as to assess the adhesive strength of these coatings when applied to cement-sand plaster under conditions closely approximating those found in rural environments. Method. Various measures for mitigating the negative impact of electromagnetic radiation (EMR) in rural settings were evaluated. It was determined that the simplest and most reliable method for protecting existing buildings from EMR is the application of shielding paints to their structural envelopes. Following a lifecycle assessment of these protective-decorative coatings, a program was developed to simulate operational conditions throughout the entire service life of the coating. Result. The study presents findings from an innovative method for modifying composite materials, which ensures a highly uniform spatial distribution of conductive particles throughout the polymer matrix. An analytical link was established between the degree of filler dispersion and key performance characteristics of the coating, including shielding effectiveness, mechanical strength, adhesion to plastered surfaces, resistance to external factors, and durability. Conclusion. It was found that a uniform distribution of conductive particles within the paint significantly enhances its functionality and its capacity to shield against electromagnetic radiation. The achieved homogeneity of the polydisperse system resulted in greater resistance to external factors, with the coating retaining its original properties even after testing. Modifications to the paint composition allowed for the inclusion of additional components that bolster shielding properties and improve operational characteristics, such as adhesion to the substrate surface.
