in Pipe Deterioration

Hi, "epoxy" repair on a pipe dried off-white, matte, slightly soft and rubbery to the touch. At a distance, it looks exactly like cake icing. I'm not an expert, but it does not look like any "epoxy" I have ever used. It seems more like some kind of tough 'n' stretchy elastomer paste?

If you have any idea what this could be (brand/mfr/product name), please let me know. I am trying to match the repair.

    Hi, What's under that "epoxy"? Is it metal? Certainly there are better ways to fix it. 😇

    Yours, Larry

    Sounds like white silicon.

    iron pipe. someone else did this and I have to add to it/replicate now. hard to describe and I'd rather not post a photo.

    It's really in a whole other tougher realm than white silicone caulk, which I was just using today, for caulking siding.

    It seems like an incredibly tough rubbery paste, albeit, I have not tried to remove it. It was applied broadly to both sides of a crack. I suspect maybe it is JB Water Weld? But I have no experience with that yet. My only experience with epoxy is something that cures pretty hard to the touch and is usually shiny, not kind of soft and matte.

    Hi, Can I hazard a guess that this is a drain line? If so, A good fix would be to cut out the cracked part and use no-hubs to replace the pipe. Some Band-aids like stretchy silicon rubber tape can last a very long time, but are still considered a patch. As the cast iron loses integrity, other problems like sagging can crop up, which is a reason to go with the most durable fix. In the long run, this will save you time.

    Yours, Larry

    Thank you for the suggestion. It was not my idea to patch it like this. I am just trying to follow up.

    After a lot of research, I think odds are it was JB Water Weld epoxy "putty" that was not quite mixed in the right ratio. Several people on the interwebs mention it ending up rubbery to the touch, rather than hard, if the ratio is off. The rubbery texture is why I did not imagine it to be epoxy. I just figured it was something else entirely, some kind of elastomer or something.

    Thank you for the tip on potential sagging. I appreciate.

    some epoxies like plastic welder types are rubbery even when mixed in the right ratio. maybe it is plastidip.
