JB Waterweld

Hey guys - has anyone had any luck with waterweld inside a cooler mashtun?

Anyone ruin a beer or get sick from it?

 

Hey guys sorry to bump this but does anyone have a success story with waterweld in a plastic MLT?

 

There are lots of different types of epoxy resins out there. You would have to look at the MSDS, manufacturer recommendations and if it's food safe.

Also consider how you are trying to use it...would silicone, or another adhesive, work instead.

What are you trying to do?

 

they say it can be used on potable water tanks and withstands 300 degrees

so it might be ok

MSDS only talks about when it is a putty not when it is cured

all the best

I'm trying to fix a leaky mash tun. The hole where the fittings go is stretched out and has a dimple at the bottom that seems to be impossible to fix with more o-rings or flat washers.

 

I have used it to fix a bung fitting in my smaller mash tun with no ill effects but i only use the small tun 1-2 times a year

 

I've had exactly the opposite - an utter failure with JB waterweld (which IS food safe). It simply flaked up after a couple uses on the high-stress opening of a cooler. It simply does not adhere much (if at all) to HDPE - as is the case for most fixes.

After much research, I came across what I considered to be probably the most effective and longterm fix. It was "welding" in some HDPE into the cracks inside the cooler. I was almost about to try it until I decided, "screw it", and bought a new cooler for ~$20.

 

Yeah, epoxy can get wonky on plastics...not sure why, which is why I thought about silicon, since it bonds well to plastic and you can get food grade as well.

Possibly this product may work as well: http://www.acehardware.com/product/index.jsp?productId=3506527

Granted JB Water weld says it can adhere to plastic, and I have had very good luck with their other products...

 

Yeah...I'm thinking I'll try it on my next brew day (Monday) and if I get any leaking, i'll just pick up a new cooler.

Thanks guys.
