(8) In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure. The present disclosure may be practiced without some or all of these specific details. In other instances, well-known process structures and/or processes have not been described in detail in order not to unnecessarily obscure the present disclosure.

(9) FIG. 1 is a flowchart showing a working process according to a preferred embodiment of the present disclosure. As shown in the drawing, the present disclosure includes following operations:

(10) 1) Planarization of a Work Wall-Surface

(11) A dust attached to the work wall-surface to be worked on is removed. When the work wall-surface is uneven, a cement may be plastered on the work wall-surface or the work wall-surface may be ground. This allows the work wall-surface to be planarized.

(12) 2) Drawing a Sketch on the Work Wall-Surface

(13) A sketch may be drawn on the planarized work wall-surface. FIG. 2 is a photograph showing a state in which the sketch is drawn on the work wall-surface.

(14) 3) Installing a Crack-Prevention Member on the Work Wall-Surface

(15) A crack-prevention member is installed on the sketch region, that is, a region corresponding to a cement-mortar relief-type decoration. A metal mesh such as a metal lath or a fiber mesh may be used as the crack-prevention member. The crack-prevention member may be fixed to the work wall-surface with an anchor or a nail.

(16) The crack-prevention member is intended to prevent cracks in the cement-mortar relief-type decoration made of a cement-mortar, as described below, thereby to prevent separation of the cement-mortar relief-type decoration from the work wall-surface.

(17) In one embodiment, the crack-prevention member may be attached over an entirety of the sketch area and then the cement-mortar may be plastered on the entirety of the sketch area. In another embodiment, the crack-prevention member is attached over only a portion of the sketch region, and the cement-mortar is applied to the region where the crack-prevention member is installed, and then, the crack-prevention member is attached over a remaining portion of the sketch region where the crack-prevention member was not installed, and, then, the cement-mortar is applied to the remaining portion.

(18) 4) Plastering the Cement-Mortar on the Sketch Region

(19) The cement-mortar is plastered on the sketch region. Using a trowel, the cement-mortar may be applied. Thus, as the cement-mortar is plastered, a cement-mortar relief is formed on the work wall-surface, while the crack-prevention member is embedded in the cement-mortar relief.

(20) If necessary, a mortar adhesion enhancer may be applied over the crack-prevention member, and then, the cement-mortar may be applied thereto.

(21) 5) Engraving a Pattern in the Cement-Mortar Relief

(22) A peripheral edge of the resulting cement-mortar relief is then trimmed to match a contour of the sketch. A front face portion of the cement-mortar relief is three-dimensionally carved according to a target design. Of course, if the cement-mortar is finely formed to match a shape of the sketch at the operation of plastering the cement-mortar, it may not be necessary to trim the periphery of the cement-mortar relief or carve the front face portion thereof. However, it is difficult to finely form the cement-mortar in a shape corresponding to the sketch using the trowel.

(23) This engraving operation may be performed using a tool such as a caulking hera or a sculpting knife.

(24) On the other hand, when the cement-mortar relief is hardened, it is difficult to scrape the cement-mortar relief. Thus, the cement-mortar relief must be scraped before the hardening of the cement-mortar relief. In one embodiment, a cement-mortar may be plastered over only a first portion of the sketch, and then a first cement-mortar relief may be formed and carved. Then, a cement-mortar may be plastered over only a second portion of the sketch, and then a second cement-mortar relief may be formed and carved. Then, a cement-mortar may be plastered over only a third portion of the sketch, and then a third cement-mortar relief may be formed and carved. This process may be repeated until a shape corresponding to the entire sketch is completed.

(25) This iterative approach may also be applied to the crack-prevention member. Thus, a first crack-prevention member may be installed over only a first portion of the sketch, and then, a cement-mortar may be plastered over only the first portion of the sketch, and then a first cement-mortar relief may be formed and carved. Then, a second crack-prevention member may be installed over only a second portion of the sketch, and then, a cement-mortar may be plastered over only the second portion of the sketch, and then a second cement-mortar relief may be formed and carved. Then, a third crack-prevention member may be installed over only a third portion of the sketch, and then, a cement-mortar may be plastered over only the third portion of the sketch, and then a third cement-mortar relief may be formed and carved. This process may be repeated until a shape corresponding to the entire sketch is completed.

(26) FIG. 2 shows a sketch operation. FIG. 3 to FIG. 6 show the following repetitive operations: a first crack-prevention member may be installed over only a first portion (a lower portion of a right wing) of the sketch, and then, a cement-mortar may be plastered over only the first portion of the sketch, and then a first cement-mortar relief may be formed and carved. Then, a second crack-prevention member may be installed over only a second portion (an upper portion of the right wing) of the sketch, and then, a cement-mortar may be plastered over only the second portion of the sketch, and then a second cement-mortar relief may be formed and carved. Then, a third crack-prevention member may be installed over only a third portion (a lower portion of a left wing) of the sketch, and then, a cement-mortar may be plastered over only the third portion of the sketch, and then a third cement-mortar relief may be formed and carved. Then, a fourth crack-prevention member may be installed over only a fourth portion (an upper portion of the left wing) of the sketch, and then, a cement-mortar may be plastered over only the fourth portion of the sketch, and then a fourth cement-mortar relief may be formed and carved. As shown, the entire wings may be completed. In this way, the cement-mortar relief-type decoration may be formed.

(27) 6) Coloring the Cement-Mortar Relief-Type Decoration

(28) The resulting cement-mortar relief-type decoration may be painted. In this operation, the background of the work wall-surface may also be painted. The cement-mortar relief-type decoration may be painted after it has been completely dried.

(29) The cement-mortar relief-type decoration may be painted using ordinary cement paint. Preferably, coloring pigments may be used to color the cement-mortar relief-type decoration according to one embodiment of the disclosure. Silicon may be added as a binder into the coloring pigments. When the mixture of the silicon and the pigments as described above is used, a colored layer may be rendered clearer, may be less changed, and may be less likely to be peeled off, as compared to a color layer using the cement paint.

(30) In this connection, FIG. 7 is a photograph showing that the cement-mortar relief-type decoration and the background of the work wall-surface are colored.

(31) 7) Installing an Illumination Device Around the Work Wall-Surface

(32) Once the coloring is complete as described above, the illumination device may be installed around the work wall-surface. In this embodiment, as shown in FIG. 7, the illumination device is installed at a top of the work wall-surface. FIG. 8 is a photograph showing the state of illuminating the work wall-surface by turning on the illumination device.

(33) With this illumination device, the work wall-surface may be decorated more beautifully. In particular, as the illumination device illuminates the work wall-surface at night, a different mood may be produced from the daytime mood. In addition, the illumination device may function as a streetlight.

(34) According to the present disclosure, the cement-mortar relief-type decoration is formed using a cement plastering technique. Since the cement-mortar relief-type decoration is directly formed on the work wall-surface at a work site, a mold for molding a three-dimensional ornamental object is not required.

(35) Unlike the prior art, there is no need for costly and time-consuming labor for molding the three-dimensional ornament and transporting the ornament to the work site. In particular, the cement-mortar relief-type decoration may be formed in an elaborate and complex form that is difficult to mold using a mold. Therefore, according to the demand of the consumer, it is possible to decorate the wall with various designs without limitation of the design.

(36) Although the embodiments of the present disclosure have been described with reference to the accompanying drawings, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the disclosure as defined by the appended claims. It will be appreciated that the disclosure may be embodied in other specific forms.

(37) Accordingly, it should be understood that the above-described embodiments are illustrative in all aspects and not restrictive. The scope of the present disclosure is defined by the appended claims rather than the foregoing description. It is intended that the present disclosure cover the modifications and variations of this disclosure provided they come within the scope of the appended claims and their equivalents.
