PROBLEM TO BE SOLVED: To remarkably improve weatherability over a long period of time within the property range of the tensile properties and rubber elasticity which are required for the general constructional sealing medium composition. SOLUTION: A method of sealing a construction uses a curable composition comprising (a) a vinyl polymer having a reactive silicon group, (b) a polyoxyalkylene polymer having a number average molecular weight of≥6,000 and an Mw/Mn of≤1.6, and (c) a plasticizer having an acrylic component as the sealing medium.
