8277 WaterWeld Epoxy Putty, Underwater Repair, 2 Oz

This is junk. Did not hold at all.

Not happy with product

Product did not work. I followed all the instructions carefully and after 3 days it still had not hardened. The repair I was working on was to stop small drips in a pipe and the pressure had been shut off.

Patched copper downspout

Used it to patch a corroded elbow in a very old, but still serviceable, copper downspout. Used a piece of roll fiberglass mesh as a foundation, which worked like a charm. Waterweld hardened within a few hours. It rained that night and the patch did the job.

Don’t recommend for stated use

Did not work at all on copper piping wet or dry. The only good thing was it was very easy to get out of the tube and knead into usable application.

Works great

I used this to fill in gaps on my bulkhead and it worked great.

Solid bond, quick & application.

Easy to use. Sealed up tight quickly.

Great product. Works as advertised.

THE BEST?

I have used Waterweld on a few projects and with different metals. It is easy to use and does not set too fast. Because it will set under water, I found that using wet fingers/ hands prevents the epoxy from sticking to them when working it.

REAL STRONG

IVe used this for so many things...works great for those cords that are coming undone on laptop charging cords or phone cords...worked great for plugging holes on my vehicles muffler and its like the duct tape fix all

Problem Leak Stopped!

I purchased this product a couple of weeks back to address a PVC/PVC pipe leak. The original seal of the sump pump discharge had failed after 15 years. I used the JB Waterweld to seal the gap. I sanded the pipes to remove some growths and to rough-up the surface. Then I shut down the sump and after mixing the epoxy, I rolled it into a rope shape and applied it to the gap forcing it into the gap and smoothing it on to the sanded area. After 20 minutes I had to turn the pump on as the sump was full. The seal held throughout the night and in the morning was rock solid. I'm very impressed and will keep the second tube I bought for other emergencies.

Poor Performance in Water

I bought this to repair a pool ladder crack and it was useless.

A+ on aluminum boat

Worked fantastic on an aluminum boat, plugging leaky riveted seams.

Just what I was looking for

I had a couple maple sap buckets that had pin holes in the bottom. I was looking for something safe to use to plug them with out being harmful. This product is just what I needed.

Works just like it says!!!

I bought this product for a project I was working on. It worked just as it said. JB Weld mixed easy, applied easy, and was sable to sand and paint with no problems! Durable and I use it every time. This was used on fiberglass/resin
