Either use JB Quik as others mentioned or mix the JB weld & let it start to settup before applying to the area you want to patch. It’s an epoxy, so should cure faster with heat. Another trick is to embed a piece of window screen in the putty to hold it until it sets up.
Can you dry J-B Weld with heat?
Original J-B Weld can withstand a constant temperature of 500º F. The maximum temperature threshold is approximately 600º F for a short term (10 minutes).When fully cured, J-B Weld can only be removed by grinding or filing it off, or by directly heating the product above the 600º maximum temperature threshold.
What temperature does J-B Weld need to cure?
Original J-B Weld has been proven to keep its characteristics up to -67 degrees Fahrenheit. It may take a little longer to cure if you’re applying it in cold temperatures, so using a heater or giving it extra cure time is recommended.
How long does JB Weld high heat take to cure?
J-B Weld HighHeat is designed for DIY repairs on exhaust manifolds, tail pipes, mufflers, engine blocks, duct work and other various high temperature projects. CURE AND SET TIME: After kneading the two part formula together by hand, HighHeat takes 1 hour to set and cures in 8 hours.
How strong is JB Weld extreme heat?
2,400 degrees Fahrenheit
What JB Weld ExtremeHeat Can Fix. Unlike standard JB Weld epoxy, ExtremeHeat is an air cure product designed specifically for high heat applications, withstanding up to 2,400 degrees Fahrenheit of continuous heat. This mean that your repair will last even under extreme heat conditions.
How long does it take for J-B Weld to harden?
Mixed at a ratio of 1:1, it forms a permanent bond and can be shaped, tapped, filed, sanded and drilled after curing. At room temperature, J-B Weld™ sets in 4-6 hours to a dark grey color. A full cure is reached in 15-24 hours. J-B Weld™ has a tensile strength of 5020 PSI and sets to a hard bond overnight.
How long does JB quick take to dry?
4-6 hours
KwikWeld™ has a 1:1 mixing ratio, sets in 6 minutes and is fully cured in 4-6 hours. KwikWeld™ cures to a dark grey color, is rated at a tensile strength of 3127 PSI and will withstand temperatures up to 300ºF.
How do you make epoxy harden faster?
Just Use Heat
- It is actually possible to make epoxy resin dry faster, just by using heat.
- Increase the temperature to 75-85ºF / 24-30ºC in the room where your piece is curing.
- The resin reaches 95% of its full cure within 24 hours, and 100% of its cure within 72 hours.
How do you use J-B Weld high heat?
- Prepare. Remove dirt, debris or loose contaminants from surface. Use sand paper to roughen.
- Mix. Open J-B Weld® Extreme Heat™. Thoroughly mix product.
- Apply. Use product generously, working onto surface or into hole, crack, pit or seam.
- Dry. Test cure by pressing fingernail or thumbnail into repair material.
What is the strongest J-B Weld?
J-B Weld has a tensile strength of 3960 PSI and sets to a hard bond overnight. It can withstand temperatures up to 550ºF when fully cured.
How long does J-B Weld take to cure in 40 degree weather?
This was in about 40 degree weather though and it was good enough by next day (14 hour cure time) that I could go and use the combine and it held.
Is J-B Weld stronger than welding?
The Original Cold Weld, a two-component epoxy system that was first introduced as a substitute to traditional torch welding. This J-B Weld has a tensile strength of 3960 PSI and sets to a hard bond overnight.

Can you use J-B Weld inside a microwave?
J-B Weld can withstand a constant temperature of 500 °F (260 °C), and the maximum temperature threshold is approximately 600 °F (316 °C) for 10 minutes. J-B Weld can also be used inside a microwave oven, exposed to microwave radiation instead of infrared radiation (heat).
Is J-B Weld water resistant heat?
WaterWeld™ cures to an off-white color, is rated at a tensile strength of 1300 PSI and will withstand temperatures up to 300ºF.
Is JB Weld epoxy flammable?
Due to their complex composites, all J-B Weld products are non-flammable and can offer suitable protection for standard temperatures ranging up to 260°C (500°F). In cases of excessive heat, J-B Weld ExtremeHeat™ is a safer alternative.
Can you put J-B Weld on top of J-B Weld?
JB Weld can be applied in layers. Just clean the surface thoroughly, apply the JB welding, and wait at least 8 hours to re-apply. When applying additional layers, it’s important to wait to apply until the first application is fixed.
Is J-B Weld watertight?
WaterWeld cures to an off-white color, is rated at a tensile strength of 1300 PSI and will withstand temperatures up to 300ºF. WaterWeld can withstand continuous temperatures of 300oF/149oC and intermittent temperatures of 350°F/177°C. WaterWeld is waterproof, petroleum, chemical and acid resistant once fully cured!
Do you have to wait for J-B Weld to cure?
It looks like your JB Weld product is an epoxy resin adhesive. Typically these resins take about 24 hours to cure at room temperature, around 20°C.
Does temperature affect epoxy curing?
The warmer the temperature of curing epoxy, the faster it cures (Figure 1). Heat speeds up epoxy chemsitry or the chemical reaction of epoxy components.
Can you cure epoxy in the oven?
An epoxy curing oven may be employed, but should really only be used after the mixture has hardened via its inherent curing process.
Can you cure resin in the microwave?
Several studies have examined microwave radiation as a potential heat source to cure epoxy adhesives. They have shown that the mechanical properties of adhesives cured with microwaves are similar to those of adhesives cured via conventional heating methods.
