A process has been discovered to mix and apply a mixture of a self-curable material with an accelerator which will permit the material to cure quickly on an article on which the material is applied, but not cure in the equipment and applicator conduit used to apply the quick-curable mixture. Thus process inter-, ruptions do not incur the economic and operational disadvantages inherent in a two-component system from which a quickcuring mixture of a self-curable material and accelerator is dispensed. More specifically, the process comprises applying sequentially, through the same applicator means the self-cur-, able material (no accelerator) then the mixture containing, accelerator and …
