JB Weld vs. Pratley Steel Epoxy Putty: What’s The Difference?
The main difference between JB Weld vs. Pratley Steel Epoxy Putty is:
JB Weld has a longer working time but slower cure time compared to Pratley Steel which sets and cures much faster. Both can bond to metals and multiple substrates. JB Weld has higher specified strength properties while Pratley does not provide quantitative strength data.
📝 My Hands-on Test of Pratley Steel Quickset
Once the two putty colors became one, I continued kneading the mixture in my hands for about 8 minutes. The directions provided clear guidance on the consistency to look for, and I could feel the putty becoming hardened. While it doesn’t magically transform into steel, it does become remarkably strong over the course of two days.
My first test for the Pratley Steel Putty was to repair our mailbox, which had already been broken and repaired twice before using other products like JB Weld. Unfortunately, those previous attempts didn’t hold up against the direct sun or the test of time. However, this putty proved to be a game-changer. It was incredibly easy to work with, allowing me to mold it with my hands and shape it with tools. Once set, I even painted it, and the end result looked fantastic.
In addition to mailbox repairs, I also used the Pratley Steel Putty to connect and reinforce two aluminum tubes. I had previously tested a similar product from JB Weld, but I found the Pratley putty to be drier and stiffer during the mixing process. However, both products were set up in approximately the same amount of time and exhibited similar shear strength.
The versatility of this putty impressed me further when I used it to rebuild a handle for our stovetop griddle. Despite the heat and constant use, the putty held up exceptionally well. It proved to be durable and maintained its shape, even under the demanding conditions of a hot stovetop.
Another project where the Pratley Steel Putty exceeded my expectations was the repair of a broken piece of cast iron on an antique air rifle receiver. Once fully cured, the putty became incredibly hard and allowed for easy filing and shaping. After painting the hardened putty, it seamlessly blended in with the rest of the receiver, creating a visually pleasing result.
One thing I appreciated about the Pratley Steel Putty is that a little goes a long way. It’s important to mix a small amount at a time, as it sets hard within 8 hours and fully cures after 48 hours. For rusted steel surfaces, I found that grinding them clean before application yielded the best results.
While the majority of my experiences with the Pratley Steel Putty were positive, I did encounter a couple of instances where it didn’t perform as expected. For example, when I tried to repair a pit hole leak on a 3/4″ copper hot water pipe, the putty didn’t adhere even after several attempts. It’s worth noting that this particular application might not be suitable for the putty, especially in damp areas. In such cases, alternative solutions like clamps might be more effective. Based on my experience, I understand the frustration and the feeling of having wasted money.

📝 My Hands-on Test of JB Weld
One of the standout qualities of JB Weld is its versatility. It excels in fixing a wide range of issues, from sealing leaks in old car radiators to repairing carburetors and patching up small holes. I’ve personally used it for all of these tasks, and it truly works like magic!
But JB Weld isn’t limited to automotive repairs alone. It proves itself invaluable for various DIY projects as well. For instance, I used it on a Stake-Out stick type DIY anchor, and a single tube provided enough epoxy to construct three 12-foot anchors, complete with handles and stainless tips. Remarkably, I still had 1/3 of the tube left!
Ease of Use
The ease of use and durability of JB Weld are hard to beat. It’s a two-part epoxy that hardens to a steel-like consistency, ensuring rock-solid results. Just be sure to follow the surface preparation instructions diligently. Remove any traces of grease or oil, and roughen the surface with sandpaper for optimal adhesion.
In my experience, the original formula of JB Weld tends to be stronger and more reliable in terms of adhesion compared to the quick-setting version. If you can afford to wait a couple of days for it to cure fully, you’ll see even better results. I’ve used it extensively in my auto repair shop to secure window tabs, mirrors, and other components.
Value for Money
When it comes to value for money, JB Weld is unbeatable. It’s hands down the best cold steel adhesive I’ve come across. The fact that it’s a two-part epoxy ensures a strong and long-lasting bond. It’s definitely the top choice for any project that requires a reliable two-part epoxy adhesive.
However, there are a few considerations to keep in mind. While JB Weld is excellent for most applications, I would advise against using it to adhere magnets. The metal fibers in the epoxy can encapsulate the magnet and accumulate on its surface, diminishing its effectiveness.

Q: Can JB Weld be used to glue resin to cast metal?
A: I believe it can. Just make sure to roughen the surfaces for better adhesion.
Q: Can JB Weld be
used on tires?
A: No, it’s not suitable. Tires flex and generate heat during driving, and any epoxy would be too rigid to withstand those conditions. It’s not worth risking your safety and health.
Q: Can JB Weld be used in a high-pressure water tank?
A: JB Weld has excellent bonding capabilities, but it’s important to note that no adhesive can hold better than the paint on the tank. If the tank is painted, JB Weld may rip off the paint. Additionally, if the tank has a rusted seam, no glue can prevent further rusting and potential splitting. Real welding might repair the tank, but if it’s extensively rusted inside, it would be a waste of money. The pressure inside the tank could be dangerous if the seam fails later, and no glue can prevent that.
