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

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!

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.

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.

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.

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.

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.

Got a tip off Garden Rescue programme to use this to block up a hole to make a waterfeature - and it worked! I had a very ancient butler style sink in the garden - I did use a yoghurt pot lid in the whole to give the putty something to ‘sit on’ - I really didn’t expect it to be watertight and upped the water level gradually over a few days - still no leaks! - now planted up with a solar fountain in it. Very pleased.

My lashing strap rubbed a hole in my sea kayak (apparently it was too loose!). This product says its suitable for the sea hence why I chose it. Its nice and easy to use, sets solid and sands easily. The proof will be when I next get it out on the water. But it seems a good solid fix. Of course I will come back and change my review if it doesn't hold up! Remember to wear gloves for combining and handling the product as it will irritate your skin.

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

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 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)
