PROBLEM TO BE SOLVED: To cover the outer periphery of a body in close contact in an air conditioning duct of a complicated three-dimensionally curved surface such as a straight tube-like air conditioning duct, bent part, branched part or radially enlarged or contracted part. SOLUTION: The outer periphery of a cylindrical duct body 1 is covered with putty 2 for an antidewing air conditioning duct containing 5 to 50wt.% of fiber, 95 to 50wt.% of inorganic powder and 30 to 80wt.% of water content, and then the putty 2 is dried. The powder in the putty 2 is 10 to 80% of clay mineral to improve the operability in the case of laminating the putty 2 for the duct to the body 1. 5 to 30wt.% of binder is added to the putty 2 for the duct to improve the operability and the adhesive properties to the body 1. The covering amount of the putty 2 is desirably regulated to a predetermined range of water droplet dropping limit capacity value. |
