Abstract

PURPOSE:To enable the damaged section generated on a surface at the time of executing work, of external wall panels coated with tile pattern, to be easily repaired at a low cost. CONSTITUTION:A base plate formed in the same shape as that of the one grid 1a-1e of an external wall panel 1 is coated on the same line as the tile pattern coating line of the external wall panel 1. Then, a coating film formed on the base pla-plate after dried is peeled off to set a repairing sheet 3, and the sheet 3 is fitted on every grid 1a-1e of damaged sections generated on the external wall panel 1 to be repaired.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for cleanly and easily repairing an outer wall panel having a tiled coating.

[0002]

2. Description of the Related Art In recent years, tiles, stones and the like have been increasingly used for outer walls as homes have become more sophisticated. In addition, the exterior walls are now required to have higher design quality and higher durability, and tile-like paint has been developed that expresses the high-class feeling of ceramics. The main coating is tile (ceramic) -like painting on the outer wall panels that are integrated in the factory, and transports it from the factory to the site to assemble at the site, aiming for high quality and cost reduction and easy construction. It is possible. However, tile-like painting is different from the conventional hiding type painting.
It is a semi-transparent type coating and has a two-layer structure by forming a clear coating layer on the base coating layer.

Although such a coating is excellent in weather resistance, if a damaged portion of the coating film is generated during construction, the damaged portion of the coating film becomes more noticeable as the finish of the construction is improved. In other words, the wall material is consistently manufactured and painted on the factory line,
They are transported to the site and assembled, but when they are transported from the factory to the construction site or when they are constructed, they inevitably have scratches. Therefore, in the conventional method,
If scratches etc. occur on the painted surface, the base paint is applied to that part with a brush or a spatula, and after the base paint is dried, the clear paint will be applied to repair it, but by any means,
The result was that the repair marks were conspicuous.

[0004]

If the scratches and frictional scratches have a small area, they can be easily repaired with a brush or a spatula as in the conventional method. If it occurs, repairing it in the conventional way would cause the colors to be slightly different, resulting in unevenness, making it easy to identify the repaired part, and it was not possible to finish it beautifully, which was rather dirty. And
The repair also took time.

[0005]

The problems to be solved by the present invention are as described above, and the structure is as follows in order to solve the problems. That is, a base plate having the same shape as one grid of the outer wall panel is tile-painted on the base plate in the same line as the coating line of the outer wall panel, and the dried coating film formed on the base plate is applied. A repair sheet is peeled off, and the damaged portion of the coating film formed on the outer wall panel is repaired by attaching the repair sheet in grid units.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The problems to be solved by the present invention and the means for solving the problems are as described above, and the structure of the embodiments shown in the accompanying drawings will be described. FIG. 1 is a perspective view showing the production of a repair sheet of the present invention, FIG. 2 is a perspective view showing a peeled state of the repair sheet, and FIG. 3 is a perspective view of repairing an outer wall material.
The repair sheet of the present invention is manufactured through the same steps as the steps of manufacturing the outer wall material so that the repair sheet has substantially the same material. That is, in order to make the outer wall material look like a tile being pasted on it, joint recesses are formed on the surface of the outer wall panel 1 in a grid pattern about the thickness of the tile. The tone is painted. The coating is done by performing base coating on the outer wall panel, dry baking, then clear coating, and dry baking.

The repair sheet 3 of the present invention is formed on the base plate 2, and the base plate 2 is made of a fluororesin (Teflon) plate or a plate coated with a release agent, and the joint recesses on the surface of the outer wall panel 1 are used. 1 rectangular grid separated by
If the base plate 2 is cut into the same size as a, and the base plate 2 is coated on the same line as shown in FIG. 1 in the same manner as the coating process of the outer wall panel 1, and only the coating film is peeled off as shown in FIG. 2 after dry baking. The repair sheet 3 is obtained. Since the repair sheet 3 is manufactured by the same process as the coating film on the outer wall panel 1, it has the same thickness and the same color.
Further, since they are applied almost at the same time, the secular change also progresses at about the same time, so that the appearance is almost the same even during repair after construction.

To repair with the repair sheet 3 thus obtained, for example, as shown in FIG. 3, in the case where the coating film damaged portion of the outer wall panel 1 is peeled off by a scratch, Further, the peeling portion has scratches 4 generated on the grid 1b.
In the case of, and also in the grid 1c
In such a case, the surface of the repair sheet 3 is directly wiped with a highly adhesive transparent adhesive without wiping with paper or filling with putty, etc.
It is affixed to the parts of grids 1b and 1c that need repair.

Further, in the case of a scratch having a large unevenness such as a damaged portion of the coating film damaged portion which has occurred on the grid 1d,
After filling the defective portion with a paper hook or putty and performing a pretreatment so as to obtain a substantially smooth surface, the repair sheet 3 coated with an adhesive is attached. The grid 1e is a drawing showing the state after the repair sheet 3 is attached. After that, the repair clear is applied to the surface and the edge of the repair sheet, and the gloss is adjusted to complete the work. However, the adhesive 4 does not deform or discolor by impregnating the repair sheet 3 and has high weather resistance.

[0010]

With the above construction, the present invention has the following effects. That is, even if scratches or frictional scratches occur on the painted surface during transportation or construction of the outer wall panel, a repair sheet is simply attached so that the surface scratches are covered for each grid after construction. I was able to do it. Also, since the repair sheet can be obtained at the same time as the wall panel in the same process, the appearance and thickness of the repair sheet are almost the same as the coating film on the wall panel, and the appearance after repair is almost the same as the non-repaired part It became possible to finish it. In addition, it can be applied not only to repairing tiled paint, but also to repairing exterior wall panels with a cross-cut appearance.
