Strip and clean with MEK.
Rebond with two part PVC adhesive
It is vital to use lots of MEK in order to decontaminate the surface, remove loose plasticizers, chemically abrade, and swell the material to prepare it for receiving adhesive
During the application phase, it is vital that the humidity and temperature be less than 85F / 65% RH. Isocyanate reactants are very sensitive to moisture until they are cured.
