PROBLEM TO BE SOLVED: To provide a sealant of improved design while maintaining its inherent physical properties including adhesivity and spreadability. SOLUTION: The sealant composition to be filled in joints formed by external facing material and subjected to spatula finish is such that an indeterminate sealing main material is incorporated with a granular material. The granular material comprises a thermoplastic organic resin, its shape is nearly spherical, and its granular size and compounding ratio are set so as to afford such a design as to develop surface unevenness when the sealant composition is subjected to spatula finish.
