8281 Original Cold-Weld Epoxy, Dark Grey, 10 oz | Steel-Reinforced Original Two-Part Cold-Weld Epoxy for Metal, Plastic, Wood, Concrete and Fibreglass Repairs

I've used J-B Cold-Weld Epoxy on a variety of projects, and it has consistently delivered impressive results. This product is a go-to solution for strong, permanent repairs on a wide range of materials, including metal, wood, plastic, and more. The two-part formula is easy to use—just mix equal parts of the resin and hardener, apply it to the surface, and let it cure. One of the standout features of J-B Cold-Weld is its incredible bonding strength. Once cured, it forms a solid, durable bond that can withstand high stress and pressure. I’ve used it for both household repairs and automotive fixes, and it has held up exceptionally well under different conditions. Whether you need to patch a crack in a metal frame, fix a broken tool handle, or repair a household item, this epoxy won’t let you down. Another thing I appreciate is the versatility in finishing. After the epoxy has fully cured, it can be sanded, drilled, or painted, which is perfect for creating seamless repairs that look professional. The cure time is reasonable, giving you enough time to adjust the application before it starts setting, but it doesn’t take an excessive amount of time to fully harden either. Overall, J-B Cold-Weld Epoxy is a reliable and effective solution for both small and large repair projects. It’s affordable, easy to use, and delivers results that last. I highly recommend it to anyone who needs a tough, permanent fix for their repair needs.

I bought to repair 6mm bolt fixing points ABS plastic carrying handle and mud-guard on a mobility scooter. The bolts secure a heavy gearbox, steel chassis, real axle, wheels and motor at least 15Kg. This took 2 attempts. The first failed as I tried to minimise the visual appearance of the repair and didnt use sufiffient thickness. The second attempt was a minimum of 2 mm thick and has held now for over 6 months of regular use. The repair is very visible from the underside. As with any epoxy type 'glue' it is easy to get it everywhere. I would strongly recommend gloves and glasses, and I'm someone very used to getting glues and paints on my hands. It's very black and even with acetone is hard to clean off body parts, the dining table, furniture and places other family members may not appreciate it sticking to. But this is a good thing. It's glue. We don't want it to come off stuff! JB Weld is more effective than plain epoxy adhesive but not as subtle. It sticks to things that epoxy can't. It sets harder than epoxy. In fact it sets harder than pretty much anything that I've ever squeezed out of tube! When something carries the same health warning 4 times and uses words like "respirator" and "First Aid" you know it means business! It will sand down but it's hard going by hand and clogs abrasives, So as a means of sticking stuff together it's great, but at least when I use it, It sure ain't pretty! it says setting time is 4 hours, but working time is around 20 minutes. Setting time just means it is no longer liquid, in much the same way cake mix solidifies in the oven. At this point its about as strong as cake. Unlike cake, JB Weld takes 24 hours to get strength (I found out the hard way) .

Every house should have this. Solves lots of repair problems

This easy to use product solved the outstanding issue remaining on ensuring a shower door tile surface was level enough to allow the door sweep seal to function as designed. 100% effective.

Dries as quick as it promises, dries rock hard.

Excellent strong and durable heat resistant 2 pack Epoxy (Beats todays Araldite hands down, as that stuff really isn’t what it used to be since the good old Ciba Geigy days). Highly recommended.

Easy to mix. Sets slowly (over an hour's working time) and eventually (12+ hours) forms an extremely strong bond. I used it to fix a golf club shaft into a club head. It was ideal for this. It is liquid constituency so needs to fully supported whilst it sets.

I had a crack in my clay Chiminea, I cleaned the surface after then sanding and drying it, then applied this filler, hoping that the comments it was heat resistant would be correct. Well I coated it with VHT paint after, it has not changed after many hot fires, it really goes off hard, it takes longer than say plastic padding, but it really is the business. It really is heat resistant and very tough. I have used it on other metal joining applications and it really sticks well as long as the preparations are good too. Highly recommend the Filler.

Solutionne beaucoup de choses, parfait pour moi…

Yo empecé a revisar acerca de pegamentos y encotré este que parecía demasiado bueno para ser verdad... Una, verdadera joya! tiene un gris rata horrible y huele aún peor (antes de secarse, después es completamente inodoro), pero si se usa siguiendo las instrucciones y con la proporciones 50/50 es sólido como el acero. Lo he utilizado desde para pegar partes móviles de jugetes, hasta para sellar una tubería picada de cobre y reparar una de PVC, esto tiene cerca de seis meses y no hay ningún rastro de que se afloje o se diluya. Tengan en cuenta que es un pegamento epóxico, no instantaneo; una vez aplicado, toma como 4-6 H. que se empiece a solidificar (aqui todavia se puede ajustar o mover la pieza) a las 24 H. esta completamente solidificado y a las 36 está completamente curado.

This is the stuff that you need to glue anything! Goodness Gracious! Don't start a repair job without it. I glued metal to metal, silicone to metal with it perfectly. Because it doesn't set right away, I got time to adjust and clean up as much as I need to do a prefect job.
