Abstract

PURPOSE: To remove easily, successfully, and in a short time a reactive substance spread over other than a repaired surface, by filling a repairing reactive substance into defects in an urethane molded article, and applying and pressing thereon a base material having a good adhesion with the reactive substance.
CONSTITUTION: A repairing reactive substance is filled into recessed defects in an urethane molded article surface, then a base material having a good adhesiveness with the reactive substance is applied thereon and is pressed over the molded article surface, and during or after reaction and curing of the repairing reactive substance, the adhesive base material is peeled off to remove together therewith the reactive substance that has spread over other than the recessed defects. Since urethans have a good adhesion, they are customarily molded in a manner where a releaser is applied on the surface of a mold, and the molded article surface has therefore small amounts of the releaser, so that the reactive substance spread over other than the defects can be easily removed together with the adhesive base material. On the other hand the defects have substantially no releaser, so that the repairing reactive substance can adhere thereto successfully.
