The adhesion properties of polyurethane- and polyurea-based polymer coatings designed to protect concrete were studied under the climatic conditions of Yakutia. Coated concrete samples were exposed to outdoor conditions for two years, where temperatures ranged from +20 °C in summer to –42.8 °C in winter. The results showed that climatic factors primarily affect the surface layers. During the first year, coating adhesion decreased approximately equally for all samples. However, as the testing period increased, the decrease in adhesion properties became more pronounced and uneven. This is presumably due to moisture absorption by the polymer and concrete, the intensity of which depends on the coating thickness. Freezing of moisture leads to the formation of internal stresses and microcracks, weakening the bond between the coating and concrete. Frequent temperature fluctuations accelerate this process. It was established that the physical and mechanical properties of the coatings are determined by the composition of the original components and the nature of the chemical bonds, while curing temperature has a significant impact on their mechanical characteristics.
