<p>The present invention has an external wall panel and a coating method for it. The coating method is capable of providing a stable coating in the vicinity of a corner edge area of a convex portion, even if the area has cracks, hairline cracks, blowholes and/or pinholes. The coating can solve problems caused by cracks and the like. An external wall panel has a base panel having a three-dimensional ornamental design surface, a lower coating layer formed on the surface of the base panel, a mid-coating layer formed on the lower coating layer, a first clear layer containing beads formed on the mid-coating layer, and a second clear layer made of a transparent layer or semi-transparent layer formed on the first clear layer wherein the second clear layer has a thick film layer portion in the vicinity of a corner edge of a convex portion of the three-dimensional ornamental design surface.</p> |
