１．水性厚膜型弾性塗料を上塗り塗料として使用するこ
とにより、従来のフィラーの塗装に比べ、その作業性が
改良された。1. By using the water-based thick film type elastic coating as the top coating, the workability was improved as compared with the conventional coating of the filler.
【００１３】２．上塗り塗料として使用する水性厚膜型
弾性塗料が中塗塗料の機能も有しているので経費が軽減
された。2. Since the water-based thick film type elastic coating used as the top coating also has the function of the intermediate coating, the cost was reduced.
【００１４】３．水性厚膜型弾性塗料（上塗塗料）は原
則として１回塗装であるから、従来の有機溶剤系上塗塗
料に比べ、塗装回数が削減できた。3. Since the water-based thick film type elastic paint (topcoat paint) is applied once in principle, the number of times of application can be reduced compared to the conventional organic solvent-based topcoat paint.

ていた。Example 1 A sealer (a mixture of chlorinated rubber and a mixed organic solvent consisting of toluene and xylene) was dissolved on an outer wall surface (object to be coated) having a textured pattern coating, and the solid content was 13% by weight. Therefore, it does not contain extender pigments or coloring pigments) was applied by airless spraying at an application amount of about 140 g / m 2 . After standing at room temperature for 2 hours, airless elastic water-based paint (an aqueous dispersion containing acrylic latex as the main component, the elongation of a coating film with a thickness of 1 mm shows 540% at room temperature, and is white) Painted with spray. The coating amount is 35
At 0 g / m 2 , the coating was done once. It was dried at room temperature for 24 hours. The formed coating film had a textured pattern coating film similar to the old coating film, and it was possible to reduce the number of times of coating as compared with the conventional method, to reduce the cost of raw materials, and to improve workability.
