JB Kwik Vs. JB Weld
Overview of JB Weld KwikWeld
JB Weld KwikWeld is a quick setting version of the original JB Weld epoxy cold weld system that delivers strong, lasting repairs to metal. The product sets in just 6 minutes and reaches full strength (fully cured) in 4-6 hours, making it ideal for repairing cracks, leaks, wood, fiberglass, ceramics, and other materials. With a tensile strength of 3127 PSI, JB Weld KwikWeld will withstand temperatures up to 300ºF and cure to a dark gray color. Mixing and using this product is simple, and it can be sanded, drilled, and painted once fully cured.
Overview of JB Weld (Original Cold Weld)
A two-part epoxy adhesive, JB Weld Original is intended for repairs that require a lot of strength. A variety of surfaces and structures can be repaired with this product, including aluminum, brass, copper, stainless steel, and fiberglass. This material is made of metallic compounds that have a strong bond when mixed together. It can be drilled, sanded, and painted. It takes 4-6 hours for JB Weld Original to set and it reaches its full strength in 15 to 24 hours.

Which One Is The Best? JB Weld KwikWeld or JB Weld (Original Cold Weld)?
Both JB Weld KwikWeld and JB Weld Original have strengths and weaknesses when it comes to repairing metal surfaces and structures. You can choose the one that can meet your requirements.
JB Weld KwikWeld is actually a quick setting version of Original JB Weld. So, The setting and curing time of JB Weld KwikWeld is much smaller than JB Weld Original. JB KwikWeld sets in 6 minutes and cures in 4-6 hours, while original JB Weld sets in 4-6 hours and cures in 15-24 hours.
In terms of the tensile strength of the bond, JB Weld Original is the clear winner with a tensile strength of 5020 PSI. On the other hand, JB Weld KwikWeld has a tensile strength of 3127 PSI.
Also, JB Weld Original can withstand higher temperatures than JB Weld KwikWeld. JB Weld Original cold weld will withstand temperatures up to 287ºC or 550ºF. On the other hand, JB Weld KwikWeld can only withstand temperatures up to 110ºC or 300ºF.
So, if you are doing heavy-duty repairs that need a stronger bond and high-temperature withstanding capability, then JB Weld Original cold weld is the best option for you. And when you require quick and small repairs, then JB Weld KwikWeld is the perfect product for you.

Is JB Weld Stronger Than JB Kwik?
Compared to the original JB Weld, JB Kwik has a much faster curing time, which allows for quick repairs to be made. However, this fast curing time also means that JB Kwik is not as strong or heat-resistant as JB Weld. While JB Kwik does retain its adhesion after curing, it is not as durable as JB Weld, making it more suitable for lighter applications where strength is not a primary concern. Additionally, when JB Kwik hardens, it does not shrink like JB Weld, which can make it more suitable for some projects.
Is JB KwikWeld Waterproof?
Yes, JB KwikWeld is waterproof once it has fully cured. It forms a permanent bond and seals against moisture, making it ideal for use in damp or wet environments. However, it is important to note that while JB KwikWeld is resistant to water, it may not be completely impervious to it. In extremely wet or submerged conditions, it is best to use a product specifically designed for those conditions.
Can JB Kwik Be Used On Plastic?
Yes, JB Kwik can be used on plastic. JB Kwik is a fast-setting epoxy that can be used to bond a variety of surfaces, including plastic. However, it is important to note that the bond strength may vary depending on the type of plastic and the conditions in which it will be used. Before using JB Kwik on plastic, it is recommended to test a small area to ensure compatibility and proper adhesion.
Is JB Weld Original Waterproof?
Yes, JB Weld Original is waterproof once it has fully cured. It forms a permanent bond and seals against moisture, making it ideal for use in damp or wet environments.
Last Opinion
Heavy-duty repairs should be handled with JB Weld Original. Small, quick repairs should be handled with JB Weld KwikWeld. The decision to repair lies entirely in the hands of the individual, based on the nature of the repair and their personal preferences. By taking into consideration the factors outlined in the article about jb kwik vs. jb weld, you can now make an informed choice.
