Gluing steel to polyethylene?
I bought a 55 gal polyethylene drum to use as part of a swim platform. It
has two screw in plugs. One is poly and fits tightly. The other is steel, and the thread doesn't even resemble the thread on the opening it was in; though it is a very snug fit. I doubt I will get a good seal on it. Since I will never open it, I would like to glue it in. I know nothing sticks well to poly, but I am thinking JB Weld will fill in the thread spaces, and lock the two together. But maybe silicone caulk would be a better bet. Any thoughts on the best way to seal the metal plug in? It is about 3" diameter and 1/2" of thread. I bought it at an auction as part of a large lot with all kinds of other good stuff for a dollar, and immediately sold stuff out of the lot for $3, so it was a good buy even with the wrong plug. |

It's a lot less trouble in the long run to do it right, ONCE. -- Regards, Doug Miller (alphageek at milmac dot com) It's time to throw all their damned tea in the harbor again. |

Polyethylene is almost impossible to glue. Check around, best bet would be to find somebody with the proper plug, assuming you have not fudged up the treads on the barrel too badly. If all else fails I may have one laying around. Greg |

You already know the answer. Get the right plug or weld a PE patch over the hole. It can be heat welded. |

I have found the only thing that glues polyethylene sheeting is Liquid
Nails: Projects and Construction. It should work on other Poly stuff as well. But I really thing you would be better off finding a plug that fits properly, and using teflon tape to mage it seal. Stretch |
