J-B Weld FiberWeld 1" Pipe Repair Cast

You must pay attention to the videos that demonstrate the application... However, they are all poorly done.. often leaving out important parts (It's all in the details) .. The 2-part epoxy must be thoroughly kneaded .. the next step is to add water to the rolled up tape in the sealed bag... it's sealed because it contains quite a bit of slimy yellowish goop (quite runny) which permeates the roll of tape. you agg the water for only a few seconds just to trigger the goo to harden. You have plenty if time to wrap the tape around the pipe/leak as shown.. but because of the slimy goo, the tape can slip... it takes some talent to hold the ta[pe in place as you wrap always smoothing out the wrinkles and bubbles... the tape can easily loosen, unless you are careful at tightening each wrap .. THE TAPE IS NOT STICKY yet... that's why you have to unwind the small black flexible tape (same used for bandages, but black) this tape is sticky, and stretches.. it will secure and compress the yellowish gooey tape that you first wrapped over the epoxy and pipe. Interestingly, that black tape is supposed to be removed after 5 minutes... WHY? nothing is said about that. perhaps, it's because it will help the goo solidify, now that's it's been exposed to water and air? I left it on because I wasn't convinced that the goo had hardened, and didn't want to disturb the the tape it was holding... DUH! There are many variables here... temperature will effect the cure time. Letting the black compression tape stay attached, is like keeping a wood clamp attached.... you just don't want to remove it 'till the goop is hard. Obviously, if you try and remove after the goop is hard.. you might harm the seal.. The product is fine, the instructions are very poor, a lot can go wrong when you don't get important details ... oh, the videos are helpful, but like most YouTube videos, limited

At first it appeared that it didn't stop the leak. Twenty-four hours later...no water leaking from the pipe. It's a bit messy, so you may want to have an extra pair of gloves available, but it's worth the mess.

Solved a rather big hole in pvc that had been punched out by a water freeze this winter. Easy to use and sealed like it was a new pipe 💪

I purchased this FiberWeld pipe repair cast to fix a small leak and stabilize a damaged section of pipe. I needed something quick and easy that didn’t require special tools. The instructions were clear, and the application process was straightforward. Once activated and wrapped, the material hardened as expected and formed a strong, secure seal. It adhered well and provided immediate reinforcement to the pipe, which helped stop the leak and prevent further damage. One thing to keep in mind is that this works best as a temporary or emergency repair. It’s very effective for stabilizing the issue, but it’s not a replacement for a full pipe repair or professional fix. Overall, this is a reliable solution to keep on hand for quick fixes or emergencies. It’s easy to use, works as intended, and provides peace of mind until a permanent repair can be made.

When using this adhesive if your pipe is not in an open and free area this item can be very difficult and messy to use. The pipe I wanted to repair was too close to the wall and I could not rap the adhesive around the pipe and the mess it created was terrible. The cleanup took most of the time and nothing was accomplished. The product will work but in an open space free from walls and other obstacle.

I had a small hole in the connector pipe between the inside pipe and the pipe to the hose spigot outside. I discovered it after receiving a 200 water bill. I bought this along with a couple of other things to repair the hole, since I didn't know how they would work. I decided to start with this item and guess what? I didn't need the other things I ordered! This stuff totally fixed my problem, and it wasn't complicated at all. The only mistake I made was I thought the black bandage included was the strip that you submerge to activate. It's not, you want the one in the silver bag. It's not labeled, it just has the cautions on it. Basically, I kneaded the putty and placed it over the hole. Then I activated the fiber tape, be careful, it is messy! I wrapped it around the epoxy putty and then covered it with the black bandage and left it to cure. The only problem I ran into is that you are supposed to leave the bandage on for a few minutes and then remove it. I must have left it to long because it fused to the fiber tape and I couldn't remove it. It cures in about an hour, but I waited 24 before turning on the water. I watered my yard and garden the next day and it held just fine. I saved my cheap landlord a healthy chunk of change on a plumber in about 10 minutes. If you have a small repair like I had, this stuff works wonders. Application was easy but messy due to the fiber tape, but they include gloves. The price point wasn't painful either. Definitely cheaper than a plumber!

I used this for the first time, after using the powerwrap brand for 30 years, and must say it didnt perform like the original. It took much longer to adhere, harden, and dry. The original gets hot, sets up quickly, and sheds water, dries in 20 minutes. This time, it took 30 minutes to set. It wanted to keep unraveling. Then it took an hour to harden. And no heat to signal that it was working. Then it leaked ever so slightly, requiring a 2nd application. The powerwrap, all I ever had to do, instead of dunking it in water, was to wrap a layer, spray it with a spray bottle, then wrap it completely, and spray with water. It gets hot, and solidofies in 10 minutes to a very nice seal. Idk if i got a bad apple, but it just didnt work like the original.

But these kits are actually awesome and totally effective on copper pipes. It’s a bit messy and awkward the first one, so far I’ve done three and they got easier as I went. The black “sock” that fits over the top you are apparently supposed to remove as the product dries…don’t bother, just leave it on there. If you wait a few seconds too long you won’t have a choice anyway, this is extremely strong fast drying resin stuff, that literally does harden to strong molded fiberglass, practically porcelain or something. Essentially a five step process, first shut off water mains and drain out the pipes completely, next there’s thick two tone putty, that you press and fold between your finger to mix to one grey color (gloves included for this are required it’s sticky stuff). You then apply this putty over the leak, wrapping around the area. Next there’s the goopy mess part: a roll of moist fiber tape is soaked briefly in water. You then unroll this and wrap it as tightly as possible around the putty area, good idea to go at least a couple inches on either side of this. Gloves are essential, I got a little on my land and it took about three days to get it all off. This is really goopy mess work, but once you get it, it’s sort of goof proof to get a good thick layer where you want it. Last there is a roll of sticky black sock like material you wrap over the top to secure it all in place. I’ve noticed the sticky fiber tape is bubbling a bit as you apply this. Let dry for about an hour before turning water back on. Done. This combination hardens to extremely strong hard tough sealant material. I’ve now done three leaks, all totally successful and have been totally dry for over a month. I’d believe these will last for years, possibly many years. Great stuff for the cheap relatively easy fix!
