PC-Products 025567 PC-Marine Underwater Repair Mouldable Putty Epoxy, 2 Ounce, Off White

I've had a leak from my shower hose to the wall connection and you name it I've tried it but nothing worked it would still leak and i couldn't have a shower until i brought this, I used half of the tube and followd the instructions and put all around the leaks and left it overnight although you don't have to, in the morning with baited breath i turned on the shower stepping back so not to get wet but absolutely nothing leaked and even on high was brilliant so I'm like over the moon with this product.

I dropped the shampoo bottle and the bottle top cracked the bath in an almost perfect circle about the size of a 10p. Not wearing my glasses in the shower I didn't notice and the kitchen ceiling below was soaked. Panicking that the bath was going to have to be replaced and would be out of use until then I googled how to repair and found marine putty. I broke a chunk of and mixed it in my hand, with gloves on because it starts out dk green, I pushed some into the hole from above and pushed some up from below. I used some water on my finger to try to smooth it as much as possible. I waited 24 hours just to be safe and so far it has done the job perfectly. It dried light grey and does show on the white bath but has saved a lot of money and hassle so I will live with it. I still have plenty left if anything else happens but feel confident with the repair. Edit. Still fine in 2025

Great for leaks where water pressure is holding it in place, eg wall of swimming pool. Not so good for dripping, pressurised ABS pipes that can't be turned off or taped with self-amalgamating tape - it cures well when wet, but the leak does tend to find a way through, albeit reduced. I also tried JC Water Weld which didn't work at all.

So far this has held up nicely. I used it to repair a water butt, the tap had come loose at the the thread end and there was no other way to repair it... One cannot reach it from the inside and a new tap was no good as the barrel part had been stripped. I know that patching from the outside is iffy due to adhesion forces required to keep water in is immense and whether it would stick to both the barrel and tap due to the plastic types was a gamble, but it seems too have paid off. Although I've not had a full barrel of water to test it under true pressure, it hasn't leaked at around 1/4 full. It has yet to go through the test of winter frost etc but has held up the last few months. Being solid is a problem as it can't flex with the expansion of the material it's bonded to, so consider that, but it's holding well in this application so far.

Purchased this epoxy putty 2 years go to fix a chip on the fiberglass of my caravan. it's easy to work with and gets the job done fast. The repair also appears to be holding up really well over time. It also amazes me how it hasn't solidified in the tube even after all this time!

My galvanised watering can had deveoped a leak where the spout joined the can. Not particularly serious, but when I used it water dribbled on my shoes. I chose this product because of the can carries 9 litres, and the site of the leak would be regularly in water. It is easy to use, no noxious smells, and it can be cleaned up before left to harden. And harden it does, so within 2 hours, the repair was water proof, and water went on the plants, not me. I cannot speak for major repairs, but my problem was resolved quickly and efficiently. Recommended product.

This product is fantastic. Long work time, very sticky but not to your hands. Cures quickly. Patched up quite a large hole on a GRP Drascombe hull below the water line and it was a great success.

I bought this to try to repair a small chip in my white sink, but this epoxy is a bit on the grey side. As soon as I noticed this greyish colour I removed the epoxy from my sink because I thought it would be more noticeable than the chip. But this is great epoxy otherwise! It's very soft, so it's easy to mix. Very easy! Other brands I've used are much stiffer and contain little solid chunks that are difficult to mix, but this one is the best I've ever used. The 'workable' time is also a bit longer than other brands so you have more time to reshape. If you want this epoxy to dry smooth, just wet your finger and rub the epoxy smooth immediately after you place the mixed epoxy where you need it.

Great for sealing caches of silver, gold and cold crypto wallets for debt collectors in the most remote places that has a seal that survives extreme temps. Durable for the freezing ground temps of Mayfield OH and the varying temps of AK/UT/NV/AZ burial of silver/gold/crypto cold wallets. Amazing product for the quick drying and durability in the most stressful environmental temps for storing assets for debt collectors in remote places.

Worked great

Used for above ground pool that had a few holes and it works amazing! It is a little hard to mold into place under water but not too difficult just have to play with it for a few minutes to mold it and get it flat. I used patch kits and nothing worked so glad i bought this because i really did not want to empty the whole pool just to patch the holes. Also worked on the pump hose that sprung a hole. It is very hot where I live 120 degrees in the summer and upwards so its nice to have when the heat burns holes. Make sure to mix until both layers are like a whitish grey takes about 2 minutes just using my fingers.

Worked to repair a crack in a pool wall underwater. Decent stuff.
