Customer Reviews for J-B Weld 2 oz. Waterweld Epoxy

Due to cheap a PVC fitting that developed a crack, Water Weld saves the day. Also used it on a PVC thread leak and it worked there as well. Not my first JB Weld experience but first time with Water Weld. This is your "oh poo" fix it solution.

I used this to try to repair a pinhole in a copper pipe. I prepped, cut a small amount, mixed until uniform color and applied. The material never fully hardened. I was able to cut it off with a knife. To test, I mixed a small batch, and just put it on a piece of paper. After an hour it was still rubbery. Maybe it was a bad batch. Very strange. Unfortunately I cannot recommend it for use in plumbing. In the photo, notice the score marks made with just my fingernail after an hour hardening.

I love this waterweld epoxy putty! I have two expensive pairs of headphones which broke like a cheap pair. One pair are Sony which used very cheap plastic which after about a year nearly shattered, and the other pair used thin aluminum for the frame. I thought for sure I was going to throw away my headphones, but I seen this putty in the store and tried it. Sure enough I was able to apply the putty around the break and wow it formed a rock hard repair that has lasted longer than the original materials! Thank you so much JB weld!

Last week, I noticed my basement ceiling was broken with water dripping. A 3" PVC drain pipe appeared to leak from the 90-degree elbow joint place. I called my handyman. Unfortunately, he was too busy to come. I decided to give it a try for a temporary fix. After researching and watching YouTube demos, I bought this 2 oz JB WaterWeld epoxy putty tube. Following the instructions, I fixed my leaking PVC pipe! It has been bone dry after one day. I will keep observing. There is another PVC drain pipe right next to this pipe, indicating that a conventional repair will be challenging and costly. JB WaterWeld epoxy putty solved my problem!

I applied this to a pinhole leak on 1/2 galvanized pipe. I put the whole tube and I'm still getting a slow drip leak. I routed a pex tube from the attic to above the sink to monitor the slow drip and it is still dripping a week and half after applying. I had such high hopes for this, even believing that it would eventually settle and cure even with the slow drip. I have to find another solution as a band aid.

Used this to repair several cracks in my preformed pond. Easy fix. Worked great.

Used this to try and stop a leak where a hose comes in to our portable hot water heater. Used the marine epoxy first, didn’t fix it, added 3 layers of the puddy, still leaks!!! So annoyed.

We cracked the top on a 11 thousand poly water tank. The tank looked ruined until we bought over 70 JB Waterwelds. Now the tank is back in service and holding water. Can not say enough positive about this product!

Followed waterweld instructions, mixed, cleaned ,roughed, applied 2 packs to PVC joint leak, waited 3 hrs to apply pressure -& still have leak at end of product applied at same volume.

Didn’t do what is suppose to do I will have to purchase other product to finish the expensive job now with the extra cost !

Just made a mess, doesn't work. Horrible product, I don't recommend, don't waste your money with this.

Did not stop even the tiniest pinhole in my pvc sprinkler pipe. Allowed 24 hrs before testing.

[This review was collected as part of a promotion.] I have used JB Weld products numerous times, this product worked very well. I used it to repair my sons manual go kart. The metal poles that make it up had cracks and holes and I used this product to mend them so my son could get more use out of his toy. Its super easy to use and works on a range of textures/surfaces. Its a quick and easy fix for a multitude of things!

If the product isn’t meant to work in water, and that warning or remove “water” from the product. Product instructions has three steps, and a note. No where in those is “make sure the area is completely dry”. Product says to use gloves (good recommendation as I tried once without). However, it should be noted that you can’t reuse the gloves, or use them for long. The epoxy begins hardening and sticking to the gloves more than the piping. All four joints still leaking.

[This review was collected as part of a promotion.] I used this product in a shower. It was easily to take out of the packaging. I formed the putty to fill in the area that was leaking. It’s important to use gloves. It sealed in an hour. It has been effective and waterproof. It’s a strong seal. Would recommend!

[This review was collected as part of a promotion.] This J-B weld waterweld epoxy worked well on a couple of outside decorations that needed some patch work, put some gloves on and some putty rolled it and put it where i needed and within 20 minutes it had hardened and now it can withstand the elements

[This review was collected as part of a promotion.] Received this product for free to test it out. This product worked as intended. I will recommend putting on some rubber/latex gloves before use. Just ripped off a piece and played with it until it was a solid color then pressed it up against the leaky part of anything such as pipe and it’ll worked like a champ.

[This review was collected as part of a promotion.] We needed to do a little spring upkeep on the gutters before the heavy rain season kicked off and this did the trick! There was a spot on the back patio that would always drip and was causing concrete discoloration. This patch has held through some pretty serious storms already.

It works great on several surfaces and it’s an easy fix and is quick and easy to use. I love this product and will always keep it around and to have for easy access.

[This review was collected as part of a promotion.] I had a leak under my bathroom sink and this works so great on it. I haven’t had any leaking since. Product works as stated and so far is water resistant. This is my first time using it. Has a slight fume to it, but it could be my sensitivity.

[This review was collected as part of a promotion.] This is a wonderful product it’s worked great for my house. I used this in my bathroom to cover up some water holes by my bathtub and it covered them Well . It was very easy to use . I would recommend using this to family and friends.

[This review was collected as part of a promotion.] This product is a hit or miss depending on what you are trying to fix. When trying to fix a hose it did not hold up. In my opinion it just does nkt hold up and stand to its word of working around and in water. I used on a bar of a gate and it is holding up just fine with no issues. Make sure you follow instructions and mix throughly.

[This review was collected as part of a promotion.] I love J-B weld. I’ve used this product many times before and it always works. For special projects or for general needs . Also works great for emergency situations or quick fixes around the house and outside

[This review was collected as part of a promotion.] I was in the middle of repairing my plumbing in my tub. I was not able to completely turn off the water during this repair. Thank Heavens a friend of mine told me about this waterweld epoxy! This was a complete lifesaver! I was able to apply it even underwater!

[This review was collected as part of a promotion.] I received this and hoped to use it to fix my banister in my hall that keeps breaking off. However i dont know if i used to much but it will not firm up and dry. I have waited 3 days to write this in hopes it would, unfortunately it has not. I am going to try it on another project because i really like the ease of use and no mess of the putty formula.

[This review was collected as part of a promotion.] Used this to fix a fiberglass fender flare on our truck. It worked great. We let it set for approximately 30 minutes and the cure time was about an hour. It was very easy to sand. I would recommend wearing gloves while you're working with the putty.

[This review was collected as part of a promotion.] I received this product to try it out on a leak that I had in my boat. Being let down so many times from other products like this I really didn't expect it to work but to my surprise it worked like a champ. Will definitely look for more and refer it to anyone who needs a repair.
