Development of the technological process of painting granite of the Mansurovsky deposit

Painting of facing products made of natural stone has a significant impact on the decorative value of these products. At the same time, the best decorative indicators are achieved by volumetric impregnation of the stone structure with adhesive coloring compounds. The paper focuses on the process of painting Mansurov granite with these compositions. It highlights the creation of granite samples painted in different colors and studies the influence of technological factors on the quality of products made from it. At the same time, it was found that the surfaces of the stone painted with adhesive impregnation are resistant to water, tea, coffee, sunflower, transformer and other oils spilled on them. The main result obtained in the course of this study is the theoretical justification and experimental confirmation of the possibility of painting Mansurov granite in various colors by the method of its volumetric impregnation.
