A natural stone surface sidewalk block manufacturing method is provided to improve durability and visual beauty by preventing the surface layer of a sidewalk block from bleaching due to external environment for long time. A natural stone surface sidewalk block manufacturing method comprises: a step(100) for forming a lower base layer of a sidewalk block by mixing white cement, high steel material, and water; a step(200) for forming an upper surface layer by mixing natural aggregate, water, white silica sand, and powder aggregate; a step(300) for curing the sidewalk block formed by laminating the materials and molding the sidewalk block; a step(400) for polishing the upper surface by spraying sand and air and exposing natural aggregate to outside; and a step(500) for hardening the surface by spraying water-soluble epoxy coating material on the surface of the natural aggregate exposed to outside. |
