PROBLEM TO BE SOLVED: To provide a technique which can form a finished surface high in appearance in relation to the exterior surface of a building, suppresses the temperature rise of the building, and contributes to energy saving. SOLUTION: A substrate layer (A), a heat insulating undercoat layer (B) formed from an undercoat material containing a binder and hollow particles, and a finishing coat layer (C) formed from a water base covering material comprising a synthetic resin emulsion (p), a modified condensate of an alkoxy silane having at least one polyoxyalkylene group (q), and infrared reflecting powder (r) as indispensable components and containing 1.0-40.0 pts.wt. of the modified alkoxy silane condensate (q) in terms of SiO<SB>2</SB>in relation to 100 pts.wt. of the solid content of the synthetic resin emulsion (p) and 1-200 pts.wt. of the infrared reflecting powder (r) are formed from the indoor side toward the outdoor side of the exterior surface.
