J-B Weld Original Cold-Weld Formula Steel Reinforced Epoxy

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. 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 3960 PSI and sets to a hard bond overnight. It can withstand temperatures up to 550ºF when fully cured.

Use on:
  • Automotive
  • Brick
  • Concrete
  • Epoxy and Adhesives
  • Fiberglass
  • Metal
  • And more

  • Instructions

    1. Prepare: Clean surface area of dirt, grease, oil, paint, or loose debris. For best results use a detergent or degreaser to first clean the surface, then roughen surface with file or coarse sandpaper to provide the best repair.
    2. Mix: Squeeze equal parts from each tube onto a disposable surface and mix thoroughly.
    3. Apply: Apply with appropriate tool in an even coat, weld bead or extruded shape as needed.
    4. Dry: Sets in 4-6 hours. Cures in 15-24 hours. Allow 4-6 hours before handling and 15 hours (minimum) before putting object back in use.

    and this is great stuff. some pointers
    Epoxy glues have a limited shelf life. Buy yours at a small store where the merchandise doesn't move quickly, or keep it 5 years on the shelf and it won't work as well. Don't apply it at temperatures below 60 degrees. Spend at least 2 or 3 minutes mixing it. I use a timer to be sure. Surface preparation is the key. It must be completely grease free. I use naptha (lighter fluid) if the part is very greasy, then alcohol, and acetone in that order. Or better yet, brake cleaner or Gun Scrubber, neither of which appear to leave any trace. Whatever, clean surfaces as much as you think , then some more.

    The surface MUST be rough. I use a file,very rough (#40 or #60) sandpaper or a sharp Exacto blade to make multiple cross hatch cuts- this will even work on most steels . Roughness and cuts increase the surface area, if the cuts are done right at an angle , undercut, they can also make the glue hold better.Don't touch the cleaned area after cleaning with bare fingers Mix a bit more than you need , larger quantities are easier to mix 50-50.
    Apply the mix carefully, put the pieces together so they don't move for at least 8 hours. You can speed up setting by placing the part in the sun on a warm day. I use an oven set at 100 degrees F for small parts. It is best to wait for initial l tackiness before doing this. J B Weld is very slow drying.
    Do all that and the bond is very strong

    . Re shelf - the makers of epoxy say it has a long (years) shelf life, but only if unopened. I prefer fresh stuff , why take chances on critical jobs . If it's nor important feel free to try/

    When you need a strong rigid workable (e.g. sandable and/or paintable surface) adhesive, particularly for use on metal or hard plastic, epoxy is usually the best choice. Most epoxies dry with little running or shrinkage, and so are good for filling gaps. The major drawback to epoxies is that they consist of two parts (resin and hardener) which must be mixed in small batches, and then applied with your own applicator (e.g., a toothpick or popsicle stick). Some are packaged in a dual-syringe--but that is not an adequate solution, because the components must still be manually mixed in order harden to maximum strength.

    JB-Weld is a very strong epoxy cement. JB-Weld is the cement/glue of choice when joining metal parts or filling holes in metals. Otherwise, ordinary epoxy cement or other types of cements/glues are usually better choices. Some other reviewers have complained that the descriptive name "weld" is inappropriate---to some extent that's true. JB Weld can do some jobs welding can't. Conversely some simple welding jobs like joining two thin metal rods at right angles are difficult with JB Weld.

    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. Always reinforce with metal pieces when possible. For example, rather than building up a massive flange with JB Weld, you might be able to use scrap peice of metal to form most of the flange, held in place with JB Weld. The greater the relative surface area of contact, the strong the bond will be.

    I've been using J-B Weld for 36 years. For a DIY'er with a house, workshop, vehicles, tractors and mowers, the uses are endless. I keep a supply of both the industrial size as well as the smaller size on hand. However, there is one BIG secret:


    If the joining surface of the material to be fused is not prepared correctly, it will NOT work.

    First, the surfaces must be roughed up a bit. On steel, iron, aluminum or any metal, I use a course grinding wheel if possible. A file works fine if you have a supply of elbow grease. My favorite method on small surfaces is using a tungsten carbide cutter bit with a Dremel.

    Second, clean the surface thoroughly with acetone. Do not use alcohol.

    Acetone evaporates in a very few seconds.

    Once the surface is dry, apply J-B Weld and allow it to cure. Repairing cracks is a breeze. If I have a broken item in two parts, I rig some sort of jig to keep pressure on the joint while it cures.

    With J-B Weld, Liquid Nails, Acetone and fiberglass cloth, there are not too many things that can't be repaired.

    I had a concrete fountain bowl that weighed over 200 pounds in the front yard. Weather extremes and age caused it to break in half on the pedestal. My failure to keep the drainage holes clean in winter might have had something to do with it. I cleaned it up, propped up one half on its side, covered both halves thoroughly and liberally J-B Weld and placed the halves together. I allowed them to sit there and cure for a week. I then covered both sides with a thick layer of exterior construction Liquid Nails and allowed it to dry another week before placing the heavy bowl back on the pedestal. That was over a year ago.
