    A: It is not necessary for the copper pipe to be dry, as this product is designed to set even under water. However, for the best results, ensure the application area is clean and sanded to help the epoxy adhere properly.

Q: Can you use this on automotive radiator

a year ago
1 Answer
  • A: Look to our 2120 Radiator kit for this. Be sure to have the included mat cut to size before you mix the epoxy. You will only have about 2-3 minutes to mix and apply the epoxy before it starts to set. Mix for no more than 1 minute. Apply before the mix starts to get warm in the packaging which means the epoxy is starting to cure. Contact us at jbweld.com for anymore help needed.

I had a pin hole leak on a copper pipe. I cut a piece, kneaded, and applied it to the leaking pipe using a hose clamp to keep in place. Within a few minutes the leak stopped. I dried the area and checked back 8 hours later and the area was still dry. It fixed the leak without having to cut the water off to replace the copper pipe.

Yes, I recommend this product.

The catch at the bottom of our washing machine became stripped and was spinning freely. Clothes not agitating at all. After I finally figured out this is why my fairly new thousand dollar machine wasn't getting the clothes clean I put JB WaterWeld around the spindle, placed the agitater back on and three years later it's still holding....Man do I look like a genius. Great product, Thank you.

Yes, I recommend this product.
