Product Overview

I recently had the pleasure of trying out J B Weld Original Cold Weld Steel Reinforced Epoxy for a project I was working on. This product is an alternative to traditional welding and provides a strong, lasting repair to multiple surfaces. It was perfect for my DIY needs and I can confidently say that it exceeded my expectations.

The product comes in a two part tube, which must be mixed together at a 1:1 ratio before use. After mixing, it took about 4 6 hours to set and 15 24 hours to fully cure. When cured, the epoxy has a dark grey color and is waterproof, resistant to petroleum, chemical and acid. It also has a tensile strength of 5020 PSI and can withstand temperatures up to 550 degrees Fahrenheit 287 degrees Celsius .

One of the best features of this product is its versatility it can be used on metal, plastic PVC, wood, concrete, ceramic tile and fiberglass. In addition, once cured it can be tapped, filled, sanded, molded and drilled. It s also incredibly easy to use all you need to do is mix the two tubes together and apply the epoxy with any appropriate tool like a brush or spatula.
