Blasting and Painting the Exteror of Three Five-Million Gallon Lead-Based Paint Coated Tanks without an Enshrouding Containment

Blasting and Painting the Exteror of Three Five-Million Gallon Lead-Based Paint Coated Tanks without an Enshrouding Containment
Available for download

In early 2009 the City of Sunnyvale in Northern California put out to bid a repaint of three five‐million gallon water tank exteriors. The tanks existing coatings qualified as leadbased paint with average concentrations of 120,000ppm or 12% lead. The three tanks were successfully abrasive blasted to an SSPC SP‐10 and recoated with a zinc/acrylic system without erection of an SSPC Guide 6 Type 1A enshrouding containment. This paper tells the story of how this was done successfully using standard but not often seen work practices, even though the project was right next door to an elementary school and multi‐family residential developments and so had to perform to the strictest levels of environmental standards.

This paper examines the authors successful experiences on some simple and very complex projects where both the coatings and environmental requirements were limited to a few pages. Being made up almost entirely of SSPC/NACE and PDCA standards that described “performance criteria” as opposed to being a prescriptive or proprietary type of specification defining what was to be used, when it was to be used and how it was to be done.

Recent polyurea resin technology advances have allowed for the development of value-added polyurea topcoats that are proving to be valuable alternatives for many polyurethane applications.  The development of an SSPC specification for a weatherable polyurea topcoat is discussed for the purpose of providing a standard that will be acceptable throughout our industry.

The Sunshine Skyway Cable Stay Bridge is the signature bridge in the State of Florida. During 2004 the decision was made to repaint the stay cables for corrosion protection and aesthetic issues. The authors participated in a coatings condition assessment, plan development for refurbishing the coating system, and project execution. This paper identifies areas that made the Sunshine Skyway Bridge a challenging project such as: coatings condition assessment, paint specifications, access, containment system, execution, and final acceptance.
