By forming the top coat layer c, it is a clear color and does not affect the coloring / durability treatment layer b of the middle coat, reflects sunlight (ultraviolet rays), and contains an ultraviolet absorber, so that it is colored / durable. It exerts the effect of protecting the FRP layer of the primer treatment layer a, which is vulnerable to deterioration of the treatment layer b and ultraviolet rays.

As described above, the coating repair three-layer structure of the present invention is completely different from the conventional two-layer coating structure, and the two points of the primer-treated layer a and the topcoat layer c described above are the most important constituent requirements. The top coat layer c protects and strengthens the roof material 2 or the outer wall material 3 at the same time by the action of the resin paint of the FRP structure used as the primer treatment layer a, and the top coat layer c is applied. With the resin paint, the weather resistance was improved and the durability of the formed coating film could be improved.

Therefore, it is possible to paint even the base material that could not be repainted in the past, and it is possible to maintain the appearance at the time of painting for a long period of time.

Although the examples of the present invention have been described above based on the drawings, the present invention is not limited to the illustrated examples, and the present invention is limited to the range of design changes and application variations normally performed by those skilled in the art within the range not deviating from the technical idea. It is mentioned just in case that it includes.
