J-B WELD FAQ
ANY PROJECT. ANY SURFACE. ANY TIME.
FREQUENTLY ASKED QUESTIONS:
GENERAL
WHERE CAN I SEE YOUR FULL PRODUCT CATALOGUE?
You can download our product catalogue here.
IS J-B WELD FOOD-SAFE?
When fully cured, J-B Weld is non-toxic. Our products are not rated food-safe, and we do not recommend consuming the product or using it on areas that directly touch food or beverage.
HOW CAN I REMOVE J-B WELD PRODUCTS FROM HANDS/SKIN OR SURFACES?
Acetone or acetone-based products will remove most J-B Weld from hands and most surfaces. In some instances, a light to moderate abrasive might be required.
When fully cured, some J-B Weld products can only be removed by grinding or filing it off, or by directly heating the product above the 315ºC maximum temperature threshold.
WILL J-B WELD CONDUCT ELECTRICITY?
No. J-B Weld is not considered to be a conductor. It is an insulator.
IS THERE ANYTHING THAT J-B WELD WON’T BOND TO?
Broadly speaking, most J-B Weld products will not adhere or bond well to:
Any flexible rubber surface
Canvas
Polypropylene plastic
Polyethylene plastic
Leather or Vinyl (use our LeatherWeld kit for these repairs)
WHAT CAN I USE AS A SURFACE CLEANER BEFORE USING J-B WELD? HOW ELSE SHOULD I PREPARE SURFACES?
We recommend roughing up surfaces using a light sandpaper or other abrasive cloth prior to application to ensure sufficient bond. To clean, we recommend using acetone or lacquer thinner. In the absence of these two, soap and water can be used. Just be sure that the surface is completely dry before applying J-B Weld. DO NOT use alcohol or any "cleaner" that will leave a petroleum residue.
