行っている。The surface of the manufactured panel is coated in order to impart waterproofness, freeze-thaw resistance and the like. As a coating method for this purpose, a spray coating method, a shower coating method or the like is conventionally used in the spraying method, and the coating method is usually performed twice or more.
That is, in the case of applying the second coating, a paint having a high solvent concentration is used in the first coating, the air bubbles on the panel surface are impregnated with the paint to reinforce the panel, and the second coating has a low solvent concentration. A paint is used to waterproof the panel by forming a coating film.

ことを特徴とする。[Means and Actions for Solving the Problems] The method for coating a lightweight cellular concrete panel according to the present invention comprises:
What is claimed is: 1. A spray-type painting method for a lightweight cellular concrete panel, which comprises spraying a paint containing a solvent onto a lightweight cellular concrete panel having air bubbles on its surface, wherein the panel and a coating means for spraying the paint onto the panel. The distance between and the short distance that the amount of solvent evaporated in the middle is reduced, after performing the work of spraying the paint and impregnating the air bubbles on the surface of the panel in this state, the panel and the coating means The distance between and is a long distance in which the amount of solvent that evaporates on the way is large, and in this state, the paint of the same composition is sprayed at the same solvent concentration as the above work, and a waterproof coating film is applied to the surface of the panel. It is characterized by performing the work of forming.
前記散布式塗装方法とは、スプレーコート、シャワー
コート等である。Examples of the spray coating method include spray coating and shower coating.

装手段との間の距離が相対的に短い程、途中で蒸発する
溶剤の量は少ないのでパネルに当たった際の塗料は溶剤
濃度が高いものとなる。When the distance between the panel and the coating means is relatively long, the amount of the solvent that evaporates in the middle increases, so that the paint has a low solvent concentration when hitting the panel. Further, as the distance between the panel and the coating means is relatively short, the amount of the solvent that evaporates during the process is small, so that the paint having a high solvent concentration when it hits the panel.
従って、パネル表面の気泡に塗料を含浸させてパネル

られるように比較的長い距離で塗装を行う。Therefore, when the air bubbles on the surface of the panel are impregnated with the paint to reinforce the panel, the paint is applied over a relatively short distance so that the paint having a high solvent concentration can be obtained when it hits the panel. After that, when the waterproofness of the panel is enhanced by forming a coating film, the coating is performed at a relatively long distance so that the coating material having a low solvent concentration can be obtained when the panel is hit.
パネルと塗装手段との間の距離を変える際、パネル又
は塗装手段のいずれを移動させてもよい。Either the panel or the painting means may be moved when changing the distance between the panel and the painting means.

有する塗料12となっている。Next, in this state, a paint 12 having the same solvent concentration and the same composition (solvent, pigment, etc.) as that of the paint used for the first painting is used to shower coat the panel 11 with the same spray gun 13. In this shower coat, the paint 12 when hitting the panel 11 has a low solvent concentration because the distance between the panel 11 and the spray gun 13 is relatively long, and the paint contains a large amount of solvent in the paint. Becomes Therefore, the coating material 12 has a solvent concentration suitable for enhancing the waterproof property of the panel by forming the coating film.

合することができる。According to the coating method of the autoclave curing lightweight cellular concrete panel 11 according to the present embodiment described above, the panel 11 is formed by first coating and forming a coating film by reinforcing the panel 11 by impregnating the bubbles on the surface of the panel 11 with the coating material 12. In the second painting to improve the waterproofness of the, just the panel 11 and the spray gun 13
Since it is only necessary to change the distance between and, it is possible to use the coating material 12 having the same composition and the same solvent concentration. As a result, the first and second coating materials 12 for coating can be prepared in exactly the same manner.
また、塗装の際の塗料タンクも１個だけで済むため、
省スペース化、単純化及び管理の合理化に役立つ。Also, since only one paint tank is required for painting,
It helps to save space, simplify and streamline management.
