Is there a recommended surface preparation method for applying Smooth-On epoxy adhesives?

A clean, dry surface is a necessary prerequisite for adhesive bonding. Porous materials are simple to bond to, providing they are dry. Non-porous surfaces, as found on metal and plastic materials, should be degreased, dried, and roughened by sanding, sandblasting or chemical etching.

We have prepared an extensive guide detailing how to prepare various substrates for epoxy adhesive bonding, which you can review here:
