JB Weld Marine vs. Original
Overview of JB Weld MarineWeld
MarineWeld by JB Weld is the perfect product for any DIY repair projects involving marine or watercraft equipment. This is a two-part epoxy cold welding system that provides strong, long-lasting repairs to a variety of surfaces.
At room temperature, JB Weld MarineWeld sets in 4-6 hours and dries to a dark gray color within 15-24 hours. The material can be shaped, tapped, filed, sanded, and drilled once it has been cured and it will retain its strength above or below water’s surface. With a mixing ratio of 1:1, MarineWeld has a tensile strength of 5020 PSI.
Overview of JB Weld (Original Cold Weld)
JB Weld is an epoxy adhesive with two parts. A resin is the first component, and a hardener is the second component. Before applying these two components, you must mix them together. A solid bond is formed between these two elements, which is resistant to high temperatures and intense pressure.
The use of JB Weld creates strong and long-lasting bonds on metal and other surfaces. You only need to ensure that both parts (resin and hardener) are mixed at a 1:1 ratio. When cured, the bond will have a PSI 5020 tensile strength.

Which One Is The Best? JB Weld Marine or JB Weld (Original)?
Both JB Weld MarineWeld and JB Weld (Original Cold Weld) provide the world’s strongest bond, as well as deliver superior performance, quality, and results. Both of them are two part epoxy adhesive that are used to create strong, lasting repairs to multiple surfaces.
They are basically the same product from the same company with some differences. JB Weld MarineWeld is specially designed to work with marine and watercraft repairs. On the other hand, JB Weld (Original Cold Weld) is designed to offer durable repairs to metal and other surfaces. Both of them may work on some similar surfaces, but JB Weld MarineWeld is the winner if those surfaces have any contact with water.
JB Weld MarineWeld is made of rubber based solution so that it can work well on water related surfaces. On the other hand, JB Weld (Original Cold Weld) is made of polymer which may work well in metal and other surfaces. MarineWeld is basically a more powerful solution to water contact surfaces than Cold Weld.
You may use JB Weld (Original Cold Weld) in water contacted surfaces as it is waterproof too. But for better results you should use JB Weld MarineWeld in any project that requires strong bonds underwater.
