Get professional-grade repairs you can trust with J-B Weld 8281 Original Steel Reinforced Epoxy. Designed as a powerful alternative to torch welding, this two-part cold weld epoxy creates an incredibly strong, long-lasting bond that’s stronger than steel.
Perfect for DIY projects, automotive repairs, marine applications, crafts, and household fixes, this epoxy works on a wide range of surfaces including metal, plastic, wood, concrete, ceramic, tile, and fiberglass. Once cured, it can be drilled, sanded, tapped, molded, or painted, giving you total flexibility for any repair job.
The professional-size 10 oz pack includes steel resin and hardener, mixed at a simple 1:1 ratio. It sets in 4–6 hours and fully cures within 15–24 hours, forming a dark gray, waterproof bond that resists chemicals, petroleum, and extreme heat up to 550°F.
Whether the job is big or small, J-B Weld helps you fix it right the first time—with confidence.
