The NSRP Surface Preparation and Coatings panel sponsored a project to reduce the extent of abrasive blasting to remove aged, ultra-high solids coatings from tanks and other spaces on Navy ships. This “partial blast” process allows a percentage of remaining serviceable Ultra High Solids (UHS) to remain. After surface preparation, a single coat application of UHS coating is applied to all surfaces.

The seismic retrofitting of the County of Placer/Foresthill Road Bridge included replacing the gusset plates at the bolted connection points on the structure. Newly fabricated connection plates were prepared in the steel fabrication shop by abrasive blast cleaning and applying an inorganic zinc-rich primer. Existing connection plates were removed and the surfaces beneath abrasive blast cleaned and primed on-site with an organic (epoxy) zinc-rich primer. The connections were slip-critical.
Steel surfaces are frequently cleaned by abrasive impact prior to the application of protective coatings. The resultant surface profile must be accurately assessed to ensure compliance with job or contract specifications. But is profile height alone (the most commonly measured parameter) a good indicator of long-term coating performance?
Discussion around the basics of shop-based air powered abrasive blasting, some of the criteria which should be considered when choosing a surface preparation method and ways to reduce costs associated with this process. Technologies and Industry Best Practices are often overlooked or circumvented in the name of tradition or cost savings- but the results of these choices can be very harmful. The conversation will be centered around taking steps to maintain or increase production, while increasing departmental profits.
This paper summarizes the work performed under 2011 funding from the National Shipbuilding Research Program (NSRP) Surface Preparation and Coatings Panel.
This is a print-on-demand (POD) book that will be produced just for you in 2-5 days after your order. It should arrive at your door in about one to two weeks. However, due to supply chain and logistic challenges currently affecting the industry, it may take longer. Allow three weeks for international orders.
The SSPC Pocket Guide to Coating Information is a handy reference to those charts, standards, and calculations most frequently needed during surface preparation and coating application.
Chapters consist of topics such as soluble salts, concrete coating, inspection, corrosion basics, and more.

The life of a coating depends as much on the degree and quality of surface preparation as on the selected coating system, because most coating failures can be attributed to inadequate surface preparation or lack of coating adhesion.
In this Standards and Best Practice for Surface Preparation of Steel Substrates reference book, students and technicians are provided with the basics of numerous surface preparation techniques, pertinent technical standards, and numerous case studies on how to apply the techniques and adhere to the standards.

Few things in life improve quality, decrease costs and reduce the Environment impact. With the proper technology, using steel grit to prepare steel structures for coating can accomplish this.
Employers understand that safety is one of the most important ingredients to a successful business. However, providing a safe workplace and ensuring a safe and environmentally-sound environment is complex. Navigating the course to fool-proof safety can be mind-boggling.
This study is a result of analyzing the data and statistics from the Brooklyn Bridge project collected during lead paint removal operation. The $508 million Brooklyn Bridge Contract 6, which is still ongoing, commenced in 2010 as a part of New York City Department of Transportation’s (NYCDOT) $2.6 billion East River Bridges Capital Program.
