Blast and Paint Metal Tanks
These tanks came to us covered in rust. Our objectives were to blast to an SSPC10 near white metal in order to prep the surface for the coatings specced by our clients.
According to SSPC officials, “a near-white metal blast cleaned surface, when viewed without magnification, shall be free of all visible oil, grease, dust, dirt, mill scale, rust, coating, oxides, corrosion products, and other foreign matter, except for staining as noted. (sspc.org) ”
THE PROCESS
When these tanks arrived, all surfaces were covered with a heavy layer of rust and mill scale that needed to be removed. After the surface was prepped to the standard, Blast It Clean applied a Sherwin Williams coating system which included a Zinc Primer, Macropoxy 646, which acted as the Intermediate Coat, and an Acrolyon HS 218 for the finishing top coat.
For this project, we chose Black Beauty coal slag as our blasting media. Black Beauty coal slag is applicable on multiple surfaces. It is also an economic choice for a project on this scale. In addition, coal slags are low dust, environmentally-friendly and contain less than 0.1% of free silica, which is also safer for our blasting crew.
These tanks were delivered to our main shop, which located in Kansas City, MO. Blast It Clean has the capacity of accepting non-fixed-base projects on our work site. This offers higher flexibility for clients with medium-to-small sized projects.
