Application of the Adhesive: apply by brush or roller spreading machine a coat of Primer C to which 3% of Accelerator should have been previously added. Drying of Primer: allow to dry at least 5 to 10 minutes before spreading the PU based adhesive. With oily leathers with very high grease content it may prove necessary to apply a slight heating to the surface by means of an infra red rays lamp or an hot air drought. Once the priming coat has dried out, then the suitable PU adhesive can be applied. Thinner: ST/121
