Residual Dye (Lubricant) on Galvanized Fasteners - How Much is Too Much?

Residual Dye (Lubricant) on Galvanized Fasteners - How Much is Too Much?
Available for download

The nuts of galvanized fasteners used on bridges are coated with a wax-based lubricant that contains a dye. Once installed, the fasteners are cleaned to remove the wax prior to painting. Cleaning is typically accomplished using a combination of solvents and hand tools, but questions are often raised as to how much residual dye on the surface is acceptable for painting.

Cleaning is typically accomplished using a combination of solvents and hand tools, but questions are often raised as to how much residual dye on the surface is acceptable for painting. To gain better insight into this issue, the Florida Department of Transportation (FDOT) commissioned a research project to evaluate the performance of a bridge paint system applied to mechanically galvanized and hot dip galvanized fasteners after removal of various amounts of lubricant. This paper summarizes the research that was undertaken and the results

Painting Over Hot Dip Galvanized Steel

Product Number: 41207-348-SG
Author: Thomas J. Langill
Publication Date: 2007
$20.00

Duplex systems, also known as painting over hot dip galvanized steel, are extremely effective corrosion protection systems. However, careful surface preparation techniques need to be used to alleviate potential coating failures. The age and characteristics of the galvanized coating should be used to determine what type of surface preparation is needed.

Duplex systems, also known as painting over hot dip galvanized steel, are extremely effective corrosion protection systems. However, careful surface preparation techniques need to be used to alleviate potential coating failures. The age and characteristics of the galvanized coating should be used to determine what type of surface preparation is needed. Surface preparation should develop an anchor profile for the paint without removing the zinc coating.

Lessons Learned for Painting Over Hot-Dip Galvanizing

Product Number: 51217-048-SG
Author: Kevin Irving
Publication Date: 2017
$20.00

This paper provides an introduction to the hot-dip galvanization process as an effective and important coating option and the necessary surface preparation steps for successful painting over hot-drip galvanized steel, also known as a duplex system. Proper practices and procedures must be used to prepare new and weathered zinc-coated surfaces on after-fabrication steel products for painting to improve the bond of paint to the zinc surface and provide long-term protection against corrosion.
