Application of ambient temperature cured polymers or prepolymers to a cured elastomer

The process of bonding a tread lug laminate to a cured elastomer tire substrate, comprising the steps of:

• cleaning the surface of said cured elastomer tire substrate,
• applying from a liquid system, at least one treating agent layer, said treating agent layer selected from the group consisting of a N-halohydantoin, an N-haloamide, and an N-haloimide, said treating agent layer effectively bonded to said substrate surface, and
• applying to said substrate, in the form of a tread lug, a liquid system containing an amine curable polymer or a prepolymer in a polar solvent and an amine acuring agent, said amine curable polymer or prepolymer effectively bonding to said treating agent layer at ambient temperatures to form a tread lug.
