4 Oz Epoxy Putty Stick - Easy, Fast, Permanent Repairs Even Underwater - Repair Boat Hulls, Decks, Pools, Spas, Hot Tubs, Leaking Gaskets, Tanks, Gutters & More

I recently had the pleasure of using the Epoxy Putty Stick to tackle a pesky plumbing leak, and it exceeded all my expectations. This product truly came to my rescue, and I couldn't be more impressed. First and foremost, the ease of use of this Epoxy Putty Stick was astounding. Dealing with plumbing issues can be stressful, but this product made the process so much simpler. The included instructions were clear, concise, and incredibly helpful. Even for someone like me, who doesn't have much DIY experience, it was a breeze to follow along. Within no time, I had successfully sealed the leak, and my worries were put to rest. One of the standout features of this product is its versatility. In addition to plumbing repairs, I also used it to mend some plastic garbage holes, and it worked like a charm. This saved me the hassle of dealing with messy epoxy mixing, which I've always found to be a tedious and frustrating task. The Epoxy Putty Stick provided a convenient and mess-free alternative. Overall, I cannot recommend the Epoxy Putty Stick enough. It's a reliable and user-friendly solution for various repair needs, from plumbing leaks to fixing plastic items. If you're like me and dislike the hassle of traditional epoxy mixing, this product is a game-changer. It's a must-have addition to any DIY toolkit. Give it a try, and you won't be disappointed!

Very easy to work into shapes needed for a given repair. Sets up nicely with a good bond to the item being repaired.

I had to relocate my sand filter and pool pump due to the fact where the previous owners put it, it was sinking in the ground. Only placed on step stones not on a proper pad but I unfortunately ended up having a leak at the inlet to the filter so until I could get to the hardware store to get a few more fittings I cut some of this epoxy off and mashed it around some and put it on the adapter smashing it into the joint & smoothed it out I couldn’t believe that it worked. It was probably two weeks before I finally replaced the bad adapter and that stuff was hard as a rock even with it being wet when I put it on. Stopped the leak no problem and it held up well.

This product is awesome. I used it to patch my boat and now my boat still leaks.

Found a Brondell Swash SE600 for $100 store return on eBay. As expected, it arrived with a few problems, minor except for an internal leak (doubtless why it was returned.) Turned out the heating element for the internal hot-water tank was seated against an uneven surface (looks like a random manufacturing flaw?) I'd never used this material (Star Brite epoxy) before, but the reviews seemed authentic. It's simple to prepare, like massaging cookie dough, and only takes a few minutes. Easy to apply as well, with just enough adhesion to stay where it needs to, at least on the dry plastic surfaces I was working with. I left it alone for 90 minutes...a bit longer than it claims is necessary...and now having just tested, reassembled, re-installed, and retested it...and it's perfectly water tight . Nice to find a water-handling epoxy that actually does what it claims. We'll see how it holds up over time, but so far, so good.

The best patch substance ever.

Funcionan bien 👍

Epoxy was easy to mix together but for some reason it wouldn't stick to the aluminum floats on my pontoon boat. Was able to cram some of the epoxy between two pieces of aluminum to try to hold them together the epoxy hardened but didn't stick to either surface of the aluminum. I don't know if maybe I got a bad batch or what, but if this is the norm for this product I would not buy it again because it didn't do what it was supposed to do.

I really like this product. Its fast cure time is a good feature. I quickly repaired an underwater crack/leak in the hull of my boat - from the inside - you can also fashion plastic parts with this stuff. Epoxy is one of the best glues because it expands very slightly as it cures which presses the glue on to the bonding surface - this explains epoxy's incredible adhesion. One caution though, when mixing this product in the palm of your hand is easy you should be concerned about the potential for harmful chemicals unintentionally leaching into your body - such as BPA (which may be present??).

This thing is amazing! It's super easy to use, super fast, and it holds up! I used this to repair chips in a ceramic bathtub and I couldn't believe how well it worked. My mom now keeps a stick in her fiberglass kayak for emergency repairs. If it's calm, you could literally patch something small without taking the boat out of the water!

I tried other products to repair a crack in the basin of a resin bird bath with horrible results. I read the reviews of this product and figured, well nothing to loose... I read the directions and as indicated in the instructions and as stated in several reviews you need to work VERY quick to get the product in place once you have the epoxy mixed. You REALLY need to keep your fingers wet to avoid having the "paste" stick to your fingers and it does smell.... I got the mixed clay into the crack and the hole and then VERY quickly smoothed as best I could with wet fingers the patch. It took a while to dry completely. I let it dry 24 hours and then I could use a mouse sander to smooth out the edges. So far it is holding the water fine, AND I did scrub the patch rigorously with a scrub brush before filling it with water. Will update if there is an issue as time goes on. It was an inexpensive fix compared to the other products that I tried and did not work.

I've looked at JB weld and other brands like them and found that they only give you like a little bit so with the stick here it gives you double amount and it just works as good it's waterproof like what else do you need. It sets fast and I am waiting on getting my boat painted.

I used this for one of it's cited applications - repairing small cracks in my hot tub. I sanded the area (and a bit more to be sure) after drilling out both ends of the crack (fracture mechanics - to slow/stop the crack) and cleaning up the edges. I mixed the putty as stated, pressed it hard into the cracks (~1mm wide x 2 cm long), spreading about a 3 mm thickness about 1 cm around the crack. It set up and stuck as stated. After the stated hour I noticed a small blemish over the crack (actually raised), but thought nothing of it. I filled the tub again and noticed cracking in the epoxy itself. I wrote the manufacturer to see if I could epoxy over epoxy, but they never replied. I went ahead and sanded the epoxy and repeated the repair (on top of the epoxy). I had to do this a third time and thought it was holding. Now the cracks have opened up through the epoxy again. My conclusion - very sticky epoxy for a non-tensile situation. I will use it again for other applications and for emergencies. However, it does not seem to be able to handle minor tensile forces - this should be stated somewhere. Perhaps it was obvious I needed fiberglass, but that's my bad. UPDATE - I finally had to remove this epoxy and replace it with something with tensile strength. I removed it with a hand chisel, carefully scraping so as not to damage the acrylic of the spa. It was sticking well to the acrylic, but I was able to chip it off the acrylic in small chalky chunks - clear why there is no tensile strength. For those interested, I opted for a more expensive epoxy recommended by a spa shop called PLAST-AID - which is available on Amazon or online with other vendors in Canada. This new material hardens to a very hard consistency without any cracking whatsoever, and can be put on thin or thick depending upon your need, and you can even add colour to it with acrylic paint (I used a drop of soap dye). It dries very fast, and you need to get it onto your surface when it is wet to get good adhesion, but you do get a short time to mold it with your fingers if you want as it sets up (apparently you can put it into molds too). It sets exothermically (gets hot) and does have a powerful odour when mixed (powder and liquid mix). So far this alternative material PLAST-AID seems to be holding on my spa repairs very well (no - they didn't give me a deal to mention their product ... I just found it difficult to find the right epoxy material and wanted to help out others in my situation).
