Zusammenfassung:FIELD: mineralogy. SUBSTANCE: invention relates to treatment of naturally occurring stones and can be applied for restoration of historical monuments (sculptures, columns, buildings, and constructions). Method is characterized by that stone surface is treated with 0.005-0.12% solution of fulleren mixture in organic solvent and then with hydrophobizing organosilicon fluid, in particular with 24-26% solution of polydiethylhydrosiloxane in tetraethoxysilane or, in another embodiment, silane-siloxan-based impregnating solution Funcosil 1C serving for protection of stone materials. EFFECT: imparted durable hydrophobization to marble and alike materials. 3 cl, 1 dwg, 2 tbl, 7 ex
