Seahawk Paints Primers & Undercoaters

Seahawk Paints Marine Primers & Undercoaters: The Foundation of a Lasting Hull Finish

Every great bottom paint job starts well below the surface — with the right primer. Seahawk Paints, manufactured by New Nautical Coatings out of Clearwater, Florida, has been engineering purpose-built marine coatings since 1978. Their primers and undercoaters are no exception: designed specifically for the demands of below-the-waterline marine environments, these products serve as the critical foundation between bare hull material and a finished antifouling paint system.

Purpose-Built for the Marine Environment

Unlike general-purpose primers, Seahawk's marine primer systems are formulated to address the unique stresses that hulls face in salt water, fresh water, and everything in between. Saltwater is a highly aggressive medium that can compromise adhesion, accelerate corrosion, and allow osmotic blistering to develop beneath even a well-applied topcoat. Seahawk's primer systems are engineered to prevent exactly these failure modes, addressing hull preparation for antifouling paint, blister prevention, and barrier coating needs from a single product lineup.

Key Products: Tuff Stuff and sHAWKocon

Two products anchor Seahawk's primer range and cover the broadest range of hull preparation scenarios:

• Tuff Stuff High-Build Epoxy Primer — A fast-drying, two-part epoxy primer formulated for use over steel, fiberglass, and properly prepared aluminum surfaces below the waterline. What sets Tuff Stuff apart is its unique Sheet Silicate Technology, which delivers all-in-one osmosis protection in a single product system. It can be used as a repair coat over blistered fiberglass or as a barrier coat over unblistered hulls. With a 24-hour applicator-friendly overcoat window, it accommodates real-world boatyard schedules.
• sHAWKocon Anti-Corrosive Primer — A fast-drying, general-purpose below-the-waterline anti-corrosive primer. Comparable to industry standards, sHAWKocon is widely used for metal and fiberglass hull preparation before applying antifouling paint, offering strong adhesion and corrosion resistance where it counts most.

Why Primer Quality Matters

Skipping or skimping on primer is one of the most common — and costly — mistakes boat owners make. A quality marine primer promotes adhesion between the hull substrate and the antifouling paint above it, seals out water to prevent osmotic blistering, and protects metal surfaces from corrosion. Seahawk's primer systems are engineered specifically to exceed these requirements, ensuring that the antifouling paint applied over them performs to its full potential and lasts season after season.

Compatible with the broader Seahawk antifouling paint system, these primers integrate cleanly into a complete coating program — whether you're maintaining a trailered powerboat, a wet-slip sailboat, or a working vessel.
