A Guide to EonCoat Surface Prep by Substrate and Condition

One of the most common questions we get about EonCoat is the amount of surface preparation required for a specific substrate. We’re happy to answer these questions, especially because EonCoat usually saves contractors time and money during the surface prep process! 🙂

EonCoat saves contractors money on the application side since it only requires one coat (primer is recommended once below), but it also saves contractors time on the surface preparation side. The recommended surface preparations for EonCoat are equal to or in most cases, less time intensive than leading corrosion/abrasion coating competitors.

Below we’ve listed some of the most common surfaces used for EonCoat and the amount of preparation required for EonCoat to fully bond with the substrate:
