Interlux Paint Primers & Sealers

When it comes to marine coating systems, proper primer application is essential for topcoat adhesion, creating a smooth surface, preventing rust, and establishing a strong bond between the substrate and finish paint. Interlux Paint has built its reputation on delivering exactly this level of protection, and nowhere is this more evident than in their comprehensive Primers & Sealers lineup designed specifically for the demanding marine environment.

Marine-Grade Protection Built on 140+ Years of Expertise

A division of AkzoNobel, Interlux is one of the world's largest manufacturers of high performance boat paint, and formed in 1881, the brand has become synonymous with the highest standard of care for all kinds of vessels. This legacy translates directly into their primer formulations, which are engineered to withstand the unique challenges of saltwater, freshwater, and brackish environments where galvanic corrosion, osmotic blistering, and adhesion failure can compromise even the finest topcoat systems.

The Interlux Primer Portfolio

Interlux offers several distinct primer and sealer systems, each engineered for specific substrates and protection requirements. Primocon Primer is an essential primer designed to prevent rust and corrosion on underwater metal surfaces, making it the go-to choice for hulls, running gear, and the lower units of outboards and stern drives. It provides a barrier to reduce pitting caused by galvanic corrosion, a critical concern when dissimilar metals are present in the marine environment.

For fiberglass hulls requiring blister protection, the Interprotect 2000E system incorporates proprietary Microplates technology to create an effective barrier against water penetration and osmosis. Pre-Kote is a primer that prepares surfaces for topcoat application, ensuring maximum adhesion and a long-lasting finish, particularly when working with Interlux's polyurethane topside finishes like Brightside and Perfection.

Beyond dedicated underwater primers, Interlux also offers Epoxy Primekote for comprehensive surface preparation, Inter-Prime Wood Sealer for wooden substrates, and specialty conversion coatings that allow incompatible paint systems to work together. Primocon serves as an excellent primer for antifouling paint over sanded fiberglass and can be used as a conversion coating over unknown well-adhered antifouling paint to prevent cracking of new antifouling paint.

Application Versatility and Professional Results

What sets Interlux primers apart is their compatibility across multiple application methods and substrates. Whether you're working with aluminum, steel, fiberglass, wood, or previously painted surfaces, there's an Interlux primer specifically formulated for that scenario. The Primocon line is even available in convenient aerosol formats for touchup work on props, shafts, and hard-to-reach components.

These primers integrate seamlessly with Interlux's complete coating systems, from antifouling bottom paints like Trilux 33 and Micron CSC to high-gloss topside finishes. This system compatibility ensures that each layer works in harmony with the next, maximizing both protective performance and aesthetic results. For boatyard professionals and DIY enthusiasts alike, following Interlux's recommended primer systems eliminates the guesswork and delivers consistent, reliable outcomes season after season.
