Protect your boat’s hull with Sea Hawk AF-33 Black Ablative Antifouling Bottom Paint, designed to provide multi-season fouling protection at a single-season price. Its harder, self-polishing copolymer formula gradually wears away during use, releasing fresh biocide to help prevent marine growth while minimizing paint buildup and reducing sanding during haulout. Ideal for recreational and commercial vessels, AF-33 delivers dependable underwater protection and helps maintain a smooth hull surface.

Key Features & Benefits

• Multi-Season Protection: Provides antifouling protection against marine growth on submerged hull surfaces.
• Self-Polishing Ablative Formula: Gradually wears away during use to expose fresh biocide and maintain antifouling effectiveness.
• Reduced Paint Buildup: Helps minimize accumulated paint layers and sanding during haulout.
• Copper-Based Protection: Contains 33.6% cuprous oxide as the active biocide.
• Versatile Applications: Suitable for recreational powerboats, sailboats, fishing vessels, tugs, barges, ferries, crab traps, and other appropriate marine applications.
• Multiple Application Methods: Apply by airless or conventional spray, solvent-resistant brush, or 3/8-inch nap roller.
• Hull Compatibility: Suitable for fiberglass, wood, and properly primed steel hulls.
• Blue Finish: Semi-gloss finish for a clean, professional appearance below the waterline.
