Honestly, I’ve seen more “miracle” patch kits fail than succeed, especially in kitchens where water finds every possible escape route. That said, I totally get stretching the budget—sometimes you just need a fix that’ll hold until payday. I always tell folks: if you’re going DIY, prep is everything. Clean and dry like your life depends on it, and don’t rush the cure time. Still, if the crack starts growing or you spot mold, it’s time to call in backup. No shame in rolling the dice, just keep an eye out for leaks... and that wet dog smell.
I hear you on the “miracle” patch kits—some of those things promise the world and deliver, well, a mess. I’ve lost count of the number of times I’ve been called in after someone’s “quick fix” turned into a full-blown leak fiesta. Still, I get it—money’s tight and sometimes you just need the sink to survive until payday.
One thing that always cracks me up is when people slap a patch on without cleaning out the gunk first. Like, sure, that’ll hold... for about an hour. Prep is king, no matter what brand of kit you’re using. And yeah, that “wet dog” smell is a dead giveaway something’s gone sideways under there.
Here’s what I’m curious about: has anyone actually had one of those DIY kits last more than a few months? Or is it always a ticking time bomb? Just wondering if there’s a brand out there that actually does what it says—or if it’s all just creative marketing at this point.
I’ve tried a couple of those “miracle” kits—one was supposed to be waterproof epoxy, the other some kind of flexible tape. Both worked for a while, but honestly, neither lasted more than three months before the crack started leaking again. I think you nailed it with the prep thing. The first time, I didn’t really clean or dry the area well enough and it peeled right off. The second time I was super careful and it still failed eventually.
I get why people go for these kits—they’re cheap and seem easy—but in my experience, they’re more like a temporary band-aid than a real fix. Maybe if you’re just trying to make it through until you can afford a replacement, it makes sense. But long-term? I haven’t seen any brand that truly holds up.
That smell under the sink is the worst, by the way. It’s like a warning sign that things are about to get gross...

I get where you’re coming from, but I actually think those kits have their place—if you’re realistic about what they can do. Like you said, they’re “more like a temporary band-aid than a real fix,” and honestly, sometimes that’s all you need if you’re on a tight budget or waiting for a bigger reno. I’ve used the epoxy stuff before and yeah, it didn’t last forever, but it bought me a few months to save up for a proper replacement.
That said, I’m always a little paranoid about leaks turning into mold or water damage. The smell under the sink is definitely a red flag. Once you get that musty odor, it’s probably time to stop patching and start thinking about a real fix. I’d rather spend a bit more upfront than risk having to deal with rot or worse down the line. Sometimes cheap fixes end up costing more in the long run... especially if you miss something and it gets nasty behind the scenes.

Yeah, that smell under the sink is like nature’s way of saying “hey, you’ve pushed your luck.” I’ve had tenants try to “fix” a cracked bathroom sink with duct tape and wishful thinking—lasted about a week before water started pooling in the vanity. Honestly, those kits are fine if you just need to limp along until payday, but I’ve learned the hard way that water always finds a way out. Or worse, down. And once you’ve got water under cabinets, it’s not just a plumbing bill—you’re talking replacing particleboard, sometimes even subflooring.
I get the temptation to keep patching, especially when the budget’s tight. But if you catch it early, a real fix is usually less painful than dealing with the aftermath. Like they say, “pay now or pay later”—and later always seems to cost more.
