I totally get your hesitation about durability—I felt exactly the same way before trying a DIY kit on my kitchen sink last year. Honestly, it held up better than I expected, but I'd be lying if I said it's perfect. My kitchen sees heavy traffic (kids banging dishes around, pots and pans clanking), and after about a year, there were a couple of small cracks reappearing. Nothing major, but noticeable enough to bug me.
On the other hand, my cousin did hers in a guest bathroom using basically the same kit, and it's still looking pretty pristine after two years. So yeah, I'd say daily wear and tear definitely matters. If you're talking about a main bathroom or kitchen sink that gets constant use, you might wanna consider biting the bullet and going pro. But if it's less frequently used or you're okay with occasional touch-ups down the line... DIY could still be worth a shot. Either way, good luck—sink issues are always annoyingly tricky to sort out.
"My kitchen sees heavy traffic (kids banging dishes around, pots and pans clanking), and after about a year, there were a couple of small cracks reappearing."
Yeah, this matches my experience too. I've managed a few properties over the years, and for sinks or fixtures in high-traffic areas, DIY fixes rarely hold up long-term. Small cracks might not seem like a big deal at first, but they can lead to leaks or bigger issues down the road—definitely something you wanna avoid.
If it's your main sink getting daily abuse, I'd play it safe and get a professional repair or replacement. DIY kits are alright for quick cosmetic fixes in low-usage spots, but in kitchens or busy bathrooms, I've learned the hard way that durability matters more than saving a few bucks upfront.
I tried one of those DIY kits on my bathroom sink last year—thought I'd save myself some cash. At first, it looked pretty decent, and I was feeling pretty proud of myself. But after about six months, tiny cracks started creeping back in, especially around the drain area. I guess sinks just take more abuse than we realize, especially with kids around (mine seem to think dishes are basketballs sometimes...).
Anyway, I ended up having a plumber friend take a look, and he explained that DIY kits are mostly cosmetic—they don't really reinforce the sink structurally. He recommended either a professional resurfacing or just replacing the sink altogether. I went with replacement, and honestly, it's been worth it. No more worrying about leaks or cracks getting worse.
Maybe your situation's different, but from what I've seen, DIY fixes are usually temporary at best for high-traffic areas. Might be worth biting the bullet and getting it done properly.
I had a similar experience with a DIY bathtub refinishing kit. At first, I felt like a home improvement wizard—it looked shiny, spotless, and brand new. But after a few months, reality set in: the finish started peeling off in patches, making the tub look worse than before. My kids didn't help either, dropping shampoo bottles and toys like they were testing gravity (spoiler alert: gravity always wins).
Ended up calling in a pro to fix my mess, and he basically echoed what your plumber friend said—DIY kits are mostly cosmetic and don't hold up well under daily wear and tear. He resurfaced it properly, and it's been smooth sailing ever since.
Makes me wonder though, has anyone actually had long-term success with these DIY resurfacing kits? Maybe it's just user error on my part... wouldn't be the first time!
"Makes me wonder though, has anyone actually had long-term success with these DIY resurfacing kits?"
Honestly, I think it depends heavily on prep work and expectations. My brother refinished his sink with a DIY kit about two years ago, and surprisingly, it's still holding up pretty well. Granted, he's meticulous—spent hours sanding, cleaning, and applying thin coats. But yeah, if you've got kids dropping stuff constantly, maybe DIY isn't the best route...
