I am experiencing problems with a paint system on some vessels we built. The system is an ethyl silicate zinc primer, glass flake epoxy tie-coat and aliphatic poly top coat. The project is constructed from A516 boiler plate 1/4 in thick. Blasted to SP10 with 2.5 mil profile. Painting is being done inside a paint booth where ambient conditions clearly meet the specification. The coatings are exhibiting symptoms of solvent popping in a specific area on the exterior of the vessel. The problem only manifests itself over the back side of a weld that is on the inside of the vessel. We have made numerous adjustments to the system as well as the process to try to solve the issue. Nothing is helping. The manufactures reps are scratching their heads, and I am pulling my hair out. Any input would be welcome.
