Abstract:

This Innovations Deserving Exploratory Analysis (IDEA) project developed a method for applying protective paint coating on structural steel without the need for blast cleaning, which is undesirable in terms of costs, environmental contamination, and coating quality control when existing steel has lead-based paint present. The investigation involved three recent innovations: (1) surface tolerant, high penetration primers; (2) interlocking of primer and topcoat by embedding hollow glass fly-ash microspheres in the primer, which are then fractured to key-in the topcoat; and (3) use of advanced thermal spray and liquid applied zero volatile organic content (VOC) polymers to provide the primary environmental barrier. The results showed no significant advantage over current practice.
