The invention described herein comprises a two component sealant composition and process for applying the same for repair of ruptures, holes, cracks, etc., in hoses, pipes, tires, etc. The first component is an alpha-cyanoacrylate glue which is applied as a layer covering the rupture or crack and after a very short period the second component, a powder, is applied to the surface of the alpha-cyanoacrylate. This second component comprises a polymerization initiator having hydroxyl and/orcarboxylate groups therein, such as carbohydrates, i.e., saccharides, etc., hydrolyzed polyvinylacetate, etc. A particularly preferred initiator is alginate.
