Manufacturer

Interlux Paint

<p>Since 1881, Interlux has established itself as one of the world's leading manufacturers of high-performance marine coatings and yacht finishes. As a division of AkzoNobel, Interlux combines over a century of expertise with cutting-edge coating technology to deliver protection and beauty for vessels of all sizes, from recreational powerboats to racing sailboats and luxury yachts.</p><h3>Marine Coating Excellence</h3><p>Interlux's reputation is built on formulating specialized solutions that address the unique challenges of the marine environment. Unlike automotive or general-purpose coatings, marine paints must withstand constant exposure to UV radiation, saltwater, temperature fluctuations, and the physical stresses of wave action. Every product in the Interlux lineup is engineered specifically for marine applications, ensuring vessels receive the protection they need while maintaining a brilliant, professional appearance.</p><h3>Comprehensive Protection Systems</h3><p>The Interlux product range covers every aspect of vessel maintenance and refinishing. Their <a href="/7399-interlux-paint-wood-finishes-varnish-201205">wood finishes and varnishes</a> preserve and enhance natural teak and other marine woods with UV-resistant formulations that withstand harsh sun exposure. For hull and deck applications, <a href="/7399-interlux-paint-interlux-topside-paint-200585">topside paints</a> deliver durable, high-gloss finishes that resist chalking and fading season after season.</p><p>Below the waterline, protection becomes even more critical. <a href="/7399-interlux-paint-interlux-antifouling-paint-200583">Antifouling paints</a> prevent the growth of barnacles, weeds, and slime that can degrade hull performance and increase fuel consumption. For competitive sailors, <a href="/7399-interlux-paint-interlux-racing-bottom-paint-200584">racing bottom paints</a> are formulated to maintain smooth, low-friction surfaces that maximize speed through the water.</p><p>Proper surface preparation is essential for long-lasting results, which is why Interlux offers a complete line of <a href="/7399-interlux-paint-primers-sealers-200811">primers and sealers</a> that ensure optimal adhesion, prevent corrosion, and create the ideal foundation for topcoats. These barrier coats and anti-corrosive primers are critical for protecting fiberglass, wood, and metal surfaces from water absorption and galvanic corrosion.</p><h3>Innovation and Performance</h3><p>Interlux continues to advance marine coating technology with innovative formulations. Products like Brightside polyurethane enamel and two-part Perfection paint deliver durable, high-gloss finishes, while ablative bottom paints use self-polishing technology that continuously renews the active surface. Whether refinishing a classic wooden yacht or maintaining a modern performance cruiser, Interlux provides the coating solutions that professional boatyards and knowledgeable boat owners trust for exceptional results.</p>

Product Details

Interlux Seam Compound (Y31/QT) is a durable, flexible sealing compound formulated specifically for filling and sealing hull seams on wooden boats above the waterline. Engineered to move with the natural expansion and contraction of wood planking, this compound maintains a long-lasting, watertight seal through seasonal changes and varying moisture conditions.

Key Features:

  • Remains permanently pliable — accommodates the natural expansion and contraction of wooden planks without cracking or losing adhesion
  • Highly adhesive — bonds tenaciously to properly prepared wood and painted surfaces above the waterline
  • Easy application — smooth consistency allows effortless application with a standard putty knife
  • Tight sealing performance — fills hull seams completely to prevent water intrusion
  • White finish — paintable surface that blends cleanly under topcoats
  • Quart size — generous volume suitable for full boat seaming projects

Interlux Y31 Seam Compound is an essential part of any wooden boat maintenance toolkit. It is designed for above-waterline use where plank movement is greatest, delivering the flexibility and adhesion needed to keep seams tight season after season. Compatible with Interlux topside paints and primers for a seamless finish.
