PC Products PC-Marine Moldable Epoxy Putty, White

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

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 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.

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.
