National Shipbuilding Research Program (NSRP) project 0329, June 1991 “The Effects of Sbustrate Contaminants on The Life of Epoxy Coaatings Submerges in Sea Water” by Dr. Gerald Soltz.  This study has been controversial, but Lydia Frenzel has confirmed that, “High Humidity is the cause of “steel Rust Back” is FALSE. ” Properly cleaned steel will not rust for thousands of hours, even at 100% relative humidity. Problems with surface rerustng after blasting, indicates that there is still undesirable contamination on the steel’s surface.”    Lydia Frenzel has placed old rusty panels cleaned by abrasive blasting or by UHP WJ waterjetting (hdroblasting) above water for years.  The abrasive blast cleaned surface quickly develop localized corrosion sites around crystals of salt; the WJ cleaned panel just doesn’t turn. Dr. Soltz has later papers at SSPC proceedings and at the JPCL.  0329_soltz_salt

  11. Copyright by SSPC in 2001; Fred Berry, Wayne McGaulley, and William Shepperson- Comparison of Secondary Surface Preparation Over Waterjetting surface and the effect on Coating Performance. They conclude “Peak density is reduced by surface preparation that implements mechanical deformation of the surface, though without magnification, water jetting does not appear to impart a profile.” “The effects of water jetting on surface profile were undetectable using either Testex tape or profilometer.” “The data  show no significant difference between the adhesion of coatings to the various surface preparations used.” “Water jetting may affect substrate surface energy.” Webmaster note- The Waterjet community knows that waterjet cleaning can peen the substrate. waterjet_navy_2001_sspc_profile_berry
  12.       Federal Highway Research Administration (FHWA)- Maintenance for Bridges containing Lead Based Paint.

This is a series of cost and production comparisons for surface preparation for Steel Bridge Paint Systems (Lead Based Paint) sponsored by the Federal Highway Research Administration, 2001, with Corrpro.

“COST EFFECTIVE ALTERNATIVE METHODS FOR STEEL BRIDGE PAINT SYSTEM MAINTENANCE”
FHWA: CONTRACT NO. DTFH61-97-C-00026 September 2001, Corrpro

A cost model for bridge painting maintenance was developed to aid specifiers in evaluating the costs associated with currently available painting technologies. A myriad of design approaches, surface preparations, and coating systems are currently available to engineers tasked with maintaining painted bridges. This cost model allows quick and easy comparisons between many of the current options for steel bridge painting. The information used for the model is based on actual field observations1 and current industry practices. This “User’s Guide” describes the model’s primary components and features and the basic operation of the cost model.

The liquid pretreatment is a liquid material that is sprayed on the painted surface at a specified thickness, allowed to dry, then blasted off with the underlying lead-based paint. These products are intended to reduce the amount of leachable lead in the waste produced during blasting operations as indicated by the Toxic Characteristic Leaching Procedure (TCLP) test. Each user of these products must perform the correct testing to determine
if the waste is hazardous.  REP7
