Method for forming three-dimensional decoration on wall surface, and three-dimensional decoration formed using the method

A method for forming a three-dimensional decoration on a wall surface, wherein the method comprises:

• removing a dust from a work wall-surface;
• planarizing the work wall-surface by plastering a cement on the work wall-surface or by grinding the work wall-surface;
• drawing a sketch on the work wall-surface, wherein the sketch has a shape corresponding to the three-dimensional decoration;
• installing a crack-prevention member on the work wall-surface to suppress a separation between the three-dimensional decoration and the wall surface, wherein the crack-prevention member is embodied as a metal mesh, wherein the crack-prevention member is disposed in a first region corresponding to the sketch;
• plastering a cement-mortar in the first region on the work wall-surface so as to embed the crack-prevention member in the cement-mortar, thereby to form a cement-mortar relief;
• trimming a peripheral edge of the cement-mortar relief in a corresponding manner to a contour of the sketch;
• three-dimensionally engraving a front face portion of the cement-mortar relief to form a cement-mortar relief-type decoration as the three-dimensional decoration;
• and
• coloring the cement-mortar relief-type decoration using a mixture of silicon as a binder and coloring pigments.
