Ideal for household, automotive, plumbing, and marine applications, it’s the go-to solution for professionals and DIYers seeking lasting fixes. ## Description The simple, home-friendly process of 1:1 ratio combination of resin and hardener adhesives designed by JB-WeldTMmakes for a permanent paste ideal for all kinds of object repairs within a single day, on various types of surfaces. 1. Clean the surface to be repaired, removing all dirt, oil, grease, rust, and paint. 2. Squeeze equal parts of the resin and the hardener adhesive onto a disposable surface and mix them together. 3. Apply the mix with an appropriate tool over the clean surface. 4. Allow 4 to 6 hours for the adhesive to set, and 15 to 24 hours for it to cure completely. Broken tiles? Cracked table wood? Fractured concrete? This simple, yet long-lasting adhesive mixture is perfect for a sturdy home repair. 6 hours after application J-B WeldTM’s adhesive will have acquired a dark grey colour. After 15 to 24 hours, any object repaired will be fully cured ready for use. For best results, the surface to be repaired should first be cleaned with detergent or degreaser and then roughen with a file or coarse sandpaper. ## Features - Sets in 4-6 hours to a dark grey colour - Full cure within 15-24 hours - Tensile strength of 5020 PSI - Able to withstand temperatures up to 550ºF when fully cured - Great for household repairs, automotive, plumbing, marine, crafts & more - To use on automotive, brick, concrete, metal and more ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B014OVHAOY | | Best Sellers Rank | 9,916 in DIY & Tools (See Top 100 in DIY & Tools) 16 in Metal Filled Epoxies | | Brand | J-B Weld | | Colour | dark grey | | Compatible Material | Metal, Plastic & PVC, Wood, Concrete, Ceramic & Tile, Fiberglass | | Container Type | Tube | | Customer Reviews | 4.7 4.7 out of 5 stars (9,589) 4.7 out of 5 stars | | Full Cure Time | 24 Hours | | Global Trade Identification Number | 00043425082817 | | Item Form | Liquid | | Item Package Quantity | 1 | | Item Type Name | Plastic Weld | | Item Volume | 295.74 Millilitres | | Item Weight | 3.2 Ounces | | Manufacturer | JB WELD LTD | | Manufacturer Part Number | J-B Weld - 8281 | | Material | Epoxy Resin | | Model Number | 8281 | | Number Of Pieces | 1 | | Other Special Features Of The Product | High strength and temperature resistance | | Specific Uses For Product | Various: household repairs, automotive, plumbing, marine, crafts and more | | Tensile Strength | 5020 Pounds Per Square Inch | | Unit Count | 147.8 millilitre | | Upc | 043425082817 | | Viscosity Level | High | | Water Resistance Level | Waterproof | ## Product Details - **Brand:** J-B Weld - **Item form:** Liquid - **Material:** Epoxy Resin - **Special feature:** High strength and temperature resistance - **Specific uses for product:** Various: household repairs, automotive, plumbing, marine, crafts and more ## Images ![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 - Image 1](https://m.media-amazon.com/images/I/81i4FJ7OkNL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Does this work well as an adhesive between polystyrene and stainless steel when underwater?** A: I would say absolutely, this would work well providing the job is at least 750 meters down so that the co-efficient of expansion between the dissimilar materials is more closely aligned. This would be the case at the pressure at this depth such that the polystyrene is compressed to a much higher density. Best of luck with the joints holding. **Q: Will this glue fibreglass to wood?** A: I`m not quiet sure about fiber glass, but it sectinatly sticks all metal that I have used. Like S to a Blanket. **Q: The top of the black tube got glued shut (no thickener on it), opened it with pliers & it has a leak now. is it ok to store sealed in bag, keep using?** A: Probably not **Q: Stainless steel to stainless steel** A: I glued cast iron to cast iron because you really can't weld cast because extreme heat would fracture when it cools. So I used this with clamps set for around 3 days and it worked perfect. Regarding stainless Steel to stainless Steel you can get it welded by a good blacksmith and the welds sanded down. Yes you can use this bur you would have to clamp tight and leave for 2 to 3 days. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Is an excellent product *by on Reviewed in the United Kingdom 29 August 2026* I have to admit that I’m quite bias and like this product, it has multiple uses and is stable once hardened. 1 to 1 ratio makes mixing it easy and it bonds well to clean surfaces. I used it this time to bond 2 halves of a small bracket eaten by rust (the bracket was of a car and is not made anymore) Half of the bracket had virtually dissolved and you could see through it in places. I managed to get another bracket in similar condition ( the bracket is mirrored down a centreline ) dissolved the rust using another product cleaned them up and cut the worst one in half. I used the good half and bonded it to the better one and presto new bracket.I had to go this route as the brackets were too thin to weld.This JB Weld is such a good product to have around it gives an alternative when others won’t work. ### ⭐⭐⭐⭐⭐ Very messy but very effective *by on Reviewed in the United Kingdom 10 November 2023* 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) . ### ⭐⭐⭐⭐ Decent product, super strong but long cure time *by on Reviewed in the United Kingdom 12 April 2023* Bought this product to repair some things around the house.It's forms a much stronger bond than any of the other JB Weld products, at the cost of time. The Kqik Weld epoxies are decent, but I always find they pull clean off a surface given time or a sudden impact, even after roughing up the surface.This one on the other hand refuses to come off, works great for metal, plastic and wood, the only issue is it takes multiple hours to firm (6+) up and really does take a full 24 hours to fully cure.Use clamps to keep everything in place, don't mess with it for 24 hours and you'll be set for a really solid bond. ## Frequently Bought Together - J-B Weld 8281 Professional Size Steel Reinforced Epoxy - Hardener and Steel Pack - 10 oz - J-B Weld 8267 SteelStik Steel Reinforced Epoxy Putty Stick - 2 oz. - J-B Weld 8276 KwikWeld Quick Setting Steel Reinforced Epoxy - Dark Grey 2 oz --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/51951594-8281-original-cold-weld-epoxy-dark-grey-10-oz-steel](https://www.desertcart.com.ar/products/51951594-8281-original-cold-weld-epoxy-dark-grey-10-oz-steel) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-09-08*
