DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a repair paint suitable for repairing decorative boards used for construction such as tile or natural stone.

[0002]

2. Description of the Related Art Conventionally, decorative panels of tile-like or natural stone-like have been used as outer wall materials of buildings because they can express a high-grade appearance. However, such a decorative board often has its surface decorative layer damaged particularly during transportation, storage, construction and the like at a construction site. In particular, in the case of a decorative plate which is fixed to a base by nailing, appearance damage due to such damage easily occurs around the nailed portion.
When the decorative layer of such a decorative plate is damaged, it is repaired by applying a paint having a color similar to the base color.

[0003]

However, when a complicated spot-like pattern is formed on the surface, such as a tile-like or natural stone-like decorative board, a color similar to the above-described conventional base color is applied. Also, even when repairing by painting in a neutral color between the base color and the spot-like pattern, the difference between the damaged repaired part and the undamaged part became clear, and rather the surface makeup appearance was often impaired .

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has been developed for repairing a decorative board such as a tile or a natural stone, which can be easily repaired at a building site with good appearance. It is intended to provide a paint.

[0005]

In order to achieve the above-mentioned object, a repair paint according to the present invention comprises a paint having a spot-like pattern formed thereon.
A refinish paint to be applied to the damaged portion of the粧板, the transparent or semi-transparent resin coating, diameter in the range of 0.05~5mm
Yes, what is the base coloring paint applied to the decorative board to be repaired
The scaly or granular colored aggregates of different colors are mixed, so the tiled and natural stone-like spotted patterns can be repaired well without any noticeable defects in appearance, and without damage Is what you can do.

[0006]

According to the present invention, if the decorative layer of the decorative sheet is damaged before or after the application, the repair paint of the present invention is repaired by brushing, roller coating, etc. on the damaged area. The scaly or granular colored aggregate in the transparent or translucent resin paint of the pattern and the repair paint is compatible with each other, and the damaged portion can be made inconspicuous. When the maximum diameter of the aggregate is 5 mm or more and 0.05 mm or less, the repaired portion is too large in the former compared to the spotted pattern of the decorative board, and too small in the latter, and the repairing effect is insufficient. Becomes

In the case where the decorative layer of the decorative board is relatively smooth, it is preferable to use a material in which a flat scale-like aggregate is mixed to express the texture of the surface. In the case of a stone-like shape having fine irregularities in the layer, it is preferable to use a three-dimensionally shaped granular aggregate, which can provide a more natural repaired appearance.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a repair paint according to one embodiment of the present invention will be described.

The transparent or translucent resin paint used in the present invention is a urethane resin, an alkyd resin, a polyester resin, an acrylic resin, a silicone resin, a fluororesin or the like. An adjusting agent, an extender and the like are mixed.

The colored flake-like aggregate that can be mixed with the transparent or translucent resin paint has a flat shape and a color tone different from that of the base colored paint applied to the decorative board to be repaired. . The colored flaky aggregate may be artificially colored or the natural color of the material. The shape of the aggregate has the largest diameter of 0.05 as described above.
It is necessary to be within the range of 5 to 5 mm.
Those having a range of about 3 to 3 mm are most desirable.

The material of such aggregate is not particularly limited,
For example, plastic, mica, ceramic, metal,
Paper or the like can be used, and is added in an amount of about 5 to 70% by weight in the transparent or translucent resin paint. If the amount is less than 5% by weight, the amount of aggregate is insufficient, and if it exceeds 70% by weight, the amount of aggregate is too large, and a satisfactory repaired appearance cannot be obtained.

[0012] Instead of scaly aggregates, colored granular aggregates can also be used. This granular aggregate can be the same as the scaly aggregate except that its shape is not flat but three-dimensional. In addition, sand particles, expanded inorganic particles and the like can be added to the material. .

The repair paint of the present invention can be obtained by mixing such scaly or granular aggregates with the above-mentioned transparent or translucent resin paint.

When the repaired portion of the decorative board is repaired by using the repairing paint of the present invention, a brush, a roller,
Alternatively, it can be achieved by applying the repair paint of the present invention by spraying. When the decorative layer of the decorative board is damaged from the base colored layer, a repair paint using a colored translucent resin paint having a color tone similar to that of the base colored layer is applied to the damaged part and finished in a single application. Alternatively, the base color may be repaired by applying another colored opaque paint, and then repaired using the repair paint using the transparent or translucent resin paint of the present invention.

[0015]

As described above, the repair paint of the present invention is a transparent or translucent resin paint having a diameter of 0.05 to 5 mm.
mm range and the base applied to the decorative board to be repaired
Since the colored paint is a mixture of scale-like or granular colored aggregates of a different color, if a damaged portion occurs in the decorative layer of the decorative board before or after construction, the repair paint of the present invention When the damaged part is repaired by brushing, roller coating, etc., the spotted pattern of the natural stone or tile-like decorative board and the scaly or granular colored aggregate in the transparent or translucent resin paint of the repair paint However, the repaired appearance can be remarkably improved as compared with a conventional repair using only an opaque colored paint similar to that of the related art.

If the decorative layer of the decorative board is relatively smooth, use a flat-plate-like one in which scale-like aggregate is mixed. In such a case, by using a three-dimensional granular aggregate, the texture of the surface can be expressed, and a natural repair appearance can be achieved.
