Is J-B Weld toxic?
No. When fully cured, J-B Weld is non-toxic. However, we do not recommend consuming the product.
Can JB Weld be used as a filler?
General Principles: Although JB WELD makes an excellent filler---and can even be used to cast small parts, it is not remotely as strong as real metal used this way. Whenever possible, use JB WELD as an adhesive---a very thin layer of JB WELD holding two pieces of metal together.
Did you J-B Weld a cracked cylinder head?
So, yeah, I totally J-B Welded a cracked cylinder head. Women love me, men now want to be me. But before you give me the badge of honor, let’s be clear: This was not a crack through the combustion chamber, a water passage, or anything else under pressure. It was at the very top of the head, not the bottom.
Is JB Weld stronger than kwikweld?
Because it is faster setting, KwikWeld has about two-thirds the strength of J-B Weld; however, they are both strong enough for most projects and repairs. Click to see full answer.
How long does it take for J-B Weld to harden?
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. It can withstand temperatures up to 550ºF when fully cured.
Will heat make J-B Weld dry faster?
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.
Will J-B Weld harden if wet?
J-B Weld's WaterWeld (pictured) is a specially formulated epoxy putty that can be applied to a wet, leaking or underwater surface. Once kneaded, it can be easily molded. It has a set time of 15 to 25 min. and will be fully cured, solid as steel, after 60 min.

Will J-B Weld harden in the cold?
For wet-surface or submerged water or gasoline repairs, try our SteelStik or WaterWeld. Will J-B Weld hold up to extremely cold temperatures? Original J-B Weld has proven to maintain its characteristics to temperatures as low as -67º F.
How long does it take for JB water Weld to cure?
WaterWeld™ has a set time of 15-25 minutes and sets hard in one hour. WaterWeld™ cures to an off-white color, is rated at a tensile strength of 4370 PSI and will withstand temperatures up to 300ºF.
Will J-B Weld stop a water leak?
J-B Weld WaterWeld is a specially-formulated epoxy putty that can be applied to a wet, leaking, or even underwater surface.
Is J-B Weld a permanent fix?
J-B Weld is The Original Cold Weld two-part epoxy system that provides strong, lasting repairs to metal and multiple surfaces. Mixed at a ratio of 1:1, it forms a permanent bond and can be shaped, tapped, filed, sanded and drilled after curing.
Is JB Weld strong as real weld?
J-B Weld, known as "The Original Cold Weld," was developed as an alternative to traditional torch welding. It's designed to be extremely effective in even the harshest environments. Because it's a two-component (or 2k) epoxy system, it uses reactive chemistry to create the strongest bond possible.
Which is stronger JB Weld or epoxy?
Weld was accualy better than epoxy. Not price wise, but its quality. JB Weld actually is stronger, but not enough to make it worth it. It's very hard to get smooth.
Should you clamp JB Weld?
If you can clamp it together, that is a good idea. If not, just hold it together. The epoxy will be fully set in four hours at room temperature. If it is below 40 degrees, it will take longer.
At what temperature can I apply J-B Weld?
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 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.

What tubes does Kwikweld come in?
John, you said you had the kwik version and then said you have red and black tubes. Kwikweld comes in black and yellow tubes. They do a syringe of teh Kwik that has a red/black lable but both the kwik ones are weaker and won't take the high temp or original JB Weld.
Is a large bulk at higher temp a thin film at reduced temp?
Large bulk at higher temp, not a thin film at reduced temp. They advertise the best result attainable. Think here of concrete dam building. In these very large structures the cement will generate so much heat during curing that cooling pipes have to be inserted to prevent thermal cracking.
