PROBLEM TO BE SOLVED: To provide a joint sealer for waterproof pan which can fully exhibit waterproofness in a boundary between a waterproof pan and a floor surface; and a method of constructing the joint sealer for waterproof pan.SOLUTION: A joint sealer 10 for a waterproof pan 100 covers a boundary between the waterproof pan on which a device involving drainage (washing machine and drier) is mounted and which communicating with an exhaust port Th of a floor surface T, is installed on the floor surface, and the floor surface. The joint sealer is formed into a solid belt-like shape. The joint sealer has an U-shaped cross section in a direction intersecting the direction along the periphery of the waterproof pan so as to cover an inside surface 100g, a bottom surface 100f and an outside surface 100e of an outer peripheral edge 100b in the waterproof pan. An inside wall 10a covering the inside surface of the joint sealer has a different height from the bottom surface, from the one of an outside wall 10b covering the outside surface of the joint sealer.SELECTED DRAWING: Figure 4 |
