PROBLEM TO BE SOLVED: To provide a heat insulating and waterproofing method which effectively prevents temperature rise in a room due to direct sunlight into the room in summertime, thereby forming a comfortable living space, reduces power consumption for cooling the room, thereby contributing to energy saving, and has highly reliable waterproofing effect, thereby extending the working life of a building, and to provide a heat insulating paint for use in implementing the method. SOLUTION: The heat insulating and waterproofing method is applicable to a roof floor, a veranda, a roof portion, etc., and comprised of the steps of (1) primer coating, (2) coating of the heat insulating paint inclusive of strong inorganic foam particles, (3) coating of a waterproof paint once or more, and (4) coating of a top coat. These steps are successively carried out. The heat insulating paint for use in the above method, contains aggregate and the other fillers. Eighty percent or more of the aggregate consists of inorganic foam particles having particle size distribution in the range of 0.6 to 4.75 mm, and the surface of the particles is covered with a porcelain skin layer to form the strong inorganic foam particles. Further, the mixture ratio of a miscible liquid to the strong inorganic foam particles is set to 1:0.5 to 1:3.0 (ratio by weight).
