Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building paint surface repair sheet and a building paint surface repairing method for repairing paint defects such as scratches on the paint surfaces of interior and exterior walls of a building.

[0002]

2. Description of the Related Art Conventionally, repair of coating defects such as scratches and stains that have occurred on the coated surface is done by polishing the repaired portion on site and then repainting by bringing in a coating device. There is. Further, if the damage to be repaired is small, the repair is performed by a repair method called so-called touch-up using a repair crayon or the like.

It has been proposed in the past to attach a repair sheet to the repaired part of the automobile in order to repair it (for example, Japanese Utility Model Laid-Open No. 63-85639).
No. 1-163126, etc.), a similar sheet applied to the repair of painted surfaces such as the inner and outer walls of a building, and a repair method using such a sheet have not been disclosed yet.

[0004]

By the way, in the conventional means for repairing the painted surface of a building, a painter must be brought to the site, and power for the painter is also required, which requires a large-scale painting work. In addition to having to do it, experience and technology are required for repair painting [especially for repairing prepainted panels (units)].

Further, even if a small scratch is touch-up repaired with a repair crayon or the like, it cannot be repaired in accordance with the pattern on the painted surface. In particular, in the case of a painted surface such as a ricin coated with uneven spray coating, it is difficult to perform a clean repair by touching up.

Further, in the case where the coated surface is roughened by the aggregate-containing coating, it is necessary to match the coating of the repaired part with the color tone of the painted surface and also the roughened state of the painted surface. Therefore, there is a problem that a high degree of skill is required for repair work. Furthermore, in architectural painting, it is often the case that multiple layers of coatings with different functions are applied in layers and the specific function is obtained with the entire coating of these multiple layers. Besides matching the color tone and the roughened state of the painted surface, it is necessary to make the functionality of the coating film the same, which makes repair work even more difficult.

The present invention is intended to solve the above-mentioned problems, and it is extremely easy and in a short time to perform repairs having the same color tone, surfaceized state and functionality as those of a painted surface of a building without requiring skill. An object is to provide a paint sheet repairing sheet for a building that can be applied and a method for repairing a paint surface for a building.

[0008]

In order to achieve the above-mentioned object, a building painted surface repair sheet according to the present invention (claim 1) is formed in the same painting step as the building painted surface to be repaired. It is characterized by having a coating layer. The coated surface may be a rough finish coated surface (claim 2), or the coating layer may be formed on release paper or a resin sheet (claim 3). Further, an adhesive layer may be formed on the back surface of the coating layer formed on the release paper or the back surface of the resin sheet (claim 4). Further, a waterproof paint layer may be provided between the release paper and the paint layer (claim 5).

Further, according to the method for repairing a painted surface of a building of the present invention (claim 6), after the repaired portion of the painted surface of the building is removed to have a predetermined shape, the same painted surface as the painted surface is removed. The repair sheet provided with the coating layer formed in the step is cut into the predetermined shape, and the cut repair sheet having the predetermined shape is attached to the removed portion of the painted surface of the building. At this time, a predetermined paint may be applied to the removed portion removed into the predetermined shape, and the repair sheet may be attached to the applied predetermined paint (claim 7).

[0010]

In the building painted surface repair sheet and the building painted surface repairing method of the present invention having the above-mentioned constitution, the repair sheet includes a coating layer formed in the same painting step as the building painted surface to be repaired. When repairing the painted surface of a building, after removing the repair part to be repaired into a predetermined shape, cut the repair sheet into the predetermined shape and repair the cut predetermined shape. Since the sheet is attached to the removed part of the building painted surface,
This makes it possible to perform repairs having the same color tone, surfaceized state, and functionality as the painted surface of a building very easily and in a short time without requiring skill.
