Epoxy can definitely do the trick if you're patient, but honestly, sometimes it's just a temporary fix. Had a similar issue with an old porcelain sink—patched it up nicely, but after a few months of daily use, the crack slowly came back. Ended up replacing it with a reclaimed sink from a salvage yard. Looks great and feels good knowing it's eco-friendly too. Ever considered going the reclaimed route if your epoxy fix doesn't hold up?
"Had a similar issue with an old porcelain sink—patched it up nicely, but after a few months of daily use, the crack slowly came back."
I had a similar experience with epoxy fixes. Patched a hairline crack on my bathroom sink, and it looked solid at first. But after about six months, the crack resurfaced, probably due to temperature changes and daily use. Eventually, I bit the bullet and replaced it with a reclaimed sink as well—found a vintage cast iron one at a salvage yard. Surprisingly affordable, and it's held up great for years now. Epoxy can be handy for quick fixes, but for long-term reliability, especially with something used daily, replacement might be the way to go.
Epoxy can be hit or miss, but honestly, a lot depends on prep and application. I've had epoxy repairs last years by thoroughly sanding, cleaning, and applying multiple thin layers. Replacement's solid advice, but don't totally rule out epoxy if you're meticulous about it.
I've had mixed luck with epoxy myself. Patched up a hairline crack in our bathroom sink about three years ago—did it carefully, multiple thin coats, sanding between each. Still holding up great. But tried the same method on my kitchen sink... didn't last six months. Prep seems key, but sometimes it's just luck of the draw.
"Prep seems key, but sometimes it's just luck of the draw."
Hmm... I'd say prep is definitely important, but sink material might be a bigger factor than luck. Bathroom sinks are usually porcelain or ceramic, which bond pretty well with epoxy. Kitchen sinks, especially stainless steel or composite materials, can flex slightly under weight or temperature changes, causing epoxy repairs to fail quicker.
Have you considered trying a fiberglass repair kit instead? I've had better luck with fiberglass patches on sinks that see heavier use. They're a bit trickier to apply neatly, but once cured, they're more flexible and durable. Might be worth a shot if you're not ready to call in a pro yet.
Also curious—did you notice if the kitchen sink crack got worse gradually or just suddenly gave out? Could be a clue about what's going on underneath...
