  • How to touch up the paint on galvanized cable trays

    How to touch up the paint on galvanized cable trays

    Thoroughly wire-brush the affected areas and apply several coats of zinc-rich primer (min. 90% zinc content) to give a coating thickness at least equivalent to the original galvanizing. Many of these paints deposit zinc at about 150g/m/coat; This will usually give a dull coating. The touch-up and repair of hot-dip galvanized steel coatings is important to maintain uniform barrier and cathodic protection as well as ensure longevity. Although the hot-dip galvanized coating is very resistant to damage, small voids or defects in the coating can occur during the galvanizing. Galvanized touch-up paint is a specialized, zinc-rich compound formulated to restore the corrosion resistance of damaged hot-dip galvanized steel surfaces.
