PROBLEM TO BE SOLVED: To obtain a one-package sealant which scarcely suffers seal defect due to poor mixing occasioned when a two-package sealant is used and gives a sealing joint capable of retaining its beautiful appearance for a long time because this sealant, unlike a conventional one-package sealant, can cope with the variety of the coloration of interior and exterior decorative materials and scarcely suffers the aging of a thin-layer area and joint staining with time. SOLUTION: By adding a colorant to a moisture-curing one-package sealant composition mainly consisting of a polysulfide resin and containing no colorant and mixing them just before applying the composition to a joint, the color of the resultant composition is matched to a desired joint color.
