There are principally three methods for the removal of anti-fouling systems:
Scraping: sanding, grinding, or scraping by hand or equipment to scrape off the paint;
Blasting: grit blasting (dry blasting, wet blasting); and
water blasting/washing: (low, medium and high pressure).
Requirements for removal of AFS:
As with all facilities for coating removal, basic requirements for the facility are an impermeable floor or work surface and a means for capturing and containing AFS waste, fouling materials, dust, and, if water is used for removal, water contaminated with waste.
The floor or work surface should be clean at the start of the operation. Structures and materials within the work space that are not needed during blasting should be removed from the work area.
