AGA Announces New Touch-Up And Repair Online Video Series

One of three acceptable methods of touch-up and repair of damaged galvanized coatings, as detailed in the AGA's introductory video, is to coat the affected area with a zinc-rich touch-up paint.

Centennial, CO – The American Galvanizers Association (AGA) has developed and released the Touch-Up and Repair of Hot-Dip Galvanized Steel online video series. These six short videos detail the specifications and methods used to touch-up and repair hot-dip galvanized steel. The videos provide highly beneficial visual aids to those needing assistance with touch-up and repair, whether in the plant or the field. Topics include proper materials to use while performing the process, as well as specifications to follow, and proper application of the repair materials.

Touch-up and repair is important in maintaining the hot-dip galvanized coating’s uniform barrier and cathodic protection, which ensures maintenance-free longevity. The first video in the series introduces the process of touch-up and repair of hot-dip galvanized coatings, and the reasons why items may need to be repaired. ASTM A780, Practice for Repair of Damaged and Uncoated Areas of Hot-Dip Galvanized Coatings details three acceptable touch-up materials, zinc-based solders, zinc spray metallizing, and zinc-rich paints, which are covered in detail in later videos.
