Should a primer be applied?

The choice of primer is dependant on which adhesive is to be used:

/ hertalan ks96

/ hertalan ks137 of ks205



Before adhering an EPDM strip onto a porous substrate a primer must be applied first. The same applies to surfaces with oil, these areas should first be cleaned and then abraded prior to priming. Priming should always be completed with ks96 special primer.


For porous surfaces the contact adhesive will work as a primer itself. Applying an additional first layer by brush or roller the adhesive fulfils the priming function and creates a suitable surface for the subsequent adhesive application.
