PC-Marine Epoxy Putty, 4oz Stick, White (45565) (Pack of 1)

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.

This is epoxy rated for wet use, even underwater. Have used both this and 'water weld'. The water weld is a thick paste, so it stays put where you apply it. This is like thick honey, it will slowly ooze downhill. However, in my opinion, this 'sticks' better than water weld. If you have a situation where it will stay in place, or if you can put on more layers to build up where it oozes thin, I prefer this to the Water Weld. It adheres better, and leaves a smoother surface, so you don't have to sand as much if at all to smoothen it.

Works very well and is inexpensive.

Worked like a charm. Soft and pliable to apply, hardens to concrete strength. I didn't time it, but it was easily cured by the next day. Used UNDERWATER to seal inground pool gap. Was a little tricky to get it from floating off of the concrete surface I was working on, but it did stay after a patient minute. Strongly advise you wear gloves or apply with a tool, because it will take a while to remove the white residue from your bare hands if you opt not to. Regular soap and even garage goop didn't work, (although other compounds might have worked better)

I used this product to repair my watering can’s cracked screw on sprinkle cap (very old Rubbermaid watering can so no replacement cap is available). I was able to mold the putty around the outside of the damaged cap and once it hardened, sanded it smooth and re-drill the holes which allow the water to sprinkle out. You’d never know it wasn’t original and I now have a fully functional watering can!

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!
