Thread: Epoxy primer

  1. #1

    Default Epoxy primer

    Can Epoxy primer be thinned more than recommend for better flow, or will its quality be greatly affected?

    If you're using the EP as a sealer you wouldn't want to thin it too much because it won't "seal" the surface like it would if it was a little thicker. If you are using it as a "primer" you really shouldn't over-reduce it because you want maximum adhesion to the metal and you should go with the manufacturer's recommendation. So additional reducer is ok for a sealer but the more reducer the less of a seal.

    Most epoxies you can add up to 10% reducer and get better flow out but that is as a sealer and not directly over bare metal. If you want you could shoot one coat of unthinned epoxy then follow that up a half our later with a partially thinned coat. That way you still get the film build you need and you get the flow out you want. (some unthinned epoxies go on a little orange peely.
