Gorilla Glue: 5-10 min (open assembly), 10-15 min (closed assembly) at 20°C, 50% RH
🛠️Common Uses
JB Weld is an ideal solution for repairing leaks in various tanks, such as oil lamps or fuel containers; UV-Resistant Bonding: bond outdoor fixtures or items exposed to sunlight; JB Weld’s “ExtremeHeat” variant is designed to withstand extreme temperatures up to 2400 degrees Fahrenheit.
Gorilla Glue can be used to repair shoes made from rubber, leather, canvas, or vinyl-plastic, waders or heels, fill small gaps or holes, or use a layer on the softer parts of the shoes to protect them from early damage.
Technical Info
I just did a test on JB Weld several days ago for an analysis of JB Kwik Vs. JB Weld and part of the data in the following test have some reference to that experiment.
My Hands-on Test of JB Weld
✅Pros: JB Weld
Even without any additional reinforcements, it’s still holding up strong.
Attach a PVC Right-Angle Elbow
I had been struggling to attach a PVC right-angle elbow 
to a Corian sink overflow hole, which is located on the upper part of the sink. Despite multiple attempts with other glues, the elbow would always slide and eventually disconnect. However, after realizing that the surfaces might be too smooth, I sanded both the PVC elbow and the sinkhole to create a rougher texture. This time, when I glued them together using J.B. Weld, it worked like a charm!
Fix My Kitchenaid Planetary Head
Another usage experience that impressed me was when I used JB Weld to fix my Kitchenaid planetary head. I had a model that didn’t have a pin to hold the head to the rotating shaft, rendering it unusable for about two years. But with JB Weld, I saw a solution. I cleaned the grease off both parts, mixed a small amount of the epoxy, and carefully applied it with a q-tip, ensuring it only went where needed. After allowing it to cure for two days, I tried it out, and the result was perfect. The planetary head was securely attached to the shaft, and I could finally use my Kitchenaid mixer again. I even tugged on the head to test its strength, and it didn’t budge.
Jb Weld Oil Pan Repair
When fully cured, J-B Weld Original is waterproof and resistant to petroleum, chemical and acid. So you can use JB weld for oil pan.
Does JB Weld work on stainless steel?
Yes, JB Weld bonds different materials together. It can be used to attach stainless steel towel bars to stainless steel wall fasteners, bond copper sheets to wood, and glue resin to cast metal.
Jb Weld Mower Deck Bracket
This repair was on a lawn mower deck, a really nice and clean job to do. I cleaned the parts of rust, grime and JB weld (it just wasn’t enough to hold), repositioned the bracket, welded solid both sides (with internal weld) and applied flat black paint to protect from rust.
In this day and age, save your hard earned money!
❌Cons: JB Weld
Cure time: J.B. Weld requires a significant amount of time to fully cure and reach its maximum strength. The recommended cure time is 24 hours, which means you need to wait patiently before subjecting the repaired item to stress or load. This can be inconvenient if you’re looking for a quick fix.
What Will Jb Weld Not Stick To?
Broadly speaking, most J-B Weld products will not adhere or bond well to: Any flexible rubber surface. Canvas. Polypropylene plastic.
💬 FAQ of JB Weld Original
Q: Does this adhesive have UV resistance?
A: Yes, this particular two-part epoxy is resistant to UV rays. Its high concentration of metallic powder enhances its resistance. Additionally, you can paint over it for added protection.
Q: Will JB Weld hold a small piece of metal fuel port from a carburetor in a horizontal position until it sets? Or will gravity cause it to detach? It has a 4-6 hour set time.
A: If there is weight pulling on it, it might slip. I recommend using painter’s tape to hold it in place until it hardens. Avoid starting or operating the vehicle until the adhesive has fully set. However, if the piece will come into contact with fuel, this adhesive may not be suitable.
Q: I have a tiny nick in an injector seat. Could I use JB Weld to fill it?
A: It could work if you shape and sand it smooth. Your injector O-ring should seal it off, though.
Q: How much surface area can one pack of JB Weld cover? I need to attach a 2ft x 1ft aluminum sheet to wood.
A: One package might be sufficient, depending on the thickness and application method.
Q: Can I use JB Weld on silver? I have a silver candlestick with a broken bottom. A jeweler said it’s too big for him to repair.
A: This adhesive functions like welding material, but it won’t match the color of silver. I would recommend using it only if the repair won’t be visible, and be careful to prevent any excess adhesive from squeezing out the sides.
Q: I want to bond a piece of stainless steel to an Alumawood ceiling and hang a 3.65-pound light with magnets. Will JB Weld adhesive work?
A: Based on my personal experience, I successfully hung a heavy triple shampoo/body wash/conditioner wall dispenser on a vikrell tub/shower surround wall using this adhesive. It held up solidly, even with the weight. It’s stronger than typical glues like Gorilla Glue
. So, based on that experience, I believe it can easily support 4 pounds. I’ve also used it to fix and reattach a broken wheel on a cart, and it worked amazingly well. I highly recommend this adhesive!
Q: I’m attempting to reattach a wooden handle to a cast iron enamel Descoware frying pan (made in Belgium). Will JB Weld product work?
A: JB Weld’s “ExtremeHeat” variant is specifically designed for exhaust manifolds and tailpipes, withstanding temperatures up to 2400 degrees Fahrenheit.

My Hands-on Test of Gorilla Glue
✅Pros
I applied a dime-sized dollop on each corner of the painted cinderblock, deviating slightly from the recommended squiggly line application. I wanted to ensure easy removal of the screen frame in the future, so I opted for a more conservative amount.
Fixed Suitcase’s Handle
One example of my use so far was when the decorative silver strip on my suitcase’s pull-out handle was popping out. Before it broke off and caused either an injury to the hand or weakened the handle, I decided to apply the Gorilla Glue to reattach it permanently.
And by permanently, I mean it! This glue should hold that silver strip in place long after the rest of the suitcase is destroyed!
It is 2X Stronger than Gorilla Heavy Duty Construction Adhesive Ultimate 
.
Convenience
What impressed me further was the convenience of this glue. It comes in the perfect amount for small jobs, and its hold is excellent with a quick setting time. I appreciate that the tube has a screw cap, allowing me to close it up and save any remaining glue for later use. This adds to the overall value and longevity of the product.
❌Cons
However, there are some precautions to keep in mind when using this glue. For instance, I had to be careful while cleaning the nozzle after each use since moistening the nozzle with a towel can solidify the fresh gel almost instantly onto the nozzle. It is easier to let the gel dry a bit and break off the dried gel.
