Haha, silicone strikes again... reminds me of when I patched up a tenant's cracked porcelain sink with one of those DIY kits. Looked perfect at first, but within a month it was back to square one—hairline cracks everywhere. Ended up biting the bullet and replacing the whole thing. Curious if anyone's had better luck—anyone tried those fiberglass repair kits instead of epoxy? Heard mixed things, but never dared myself...
"Curious if anyone's had better luck—anyone tried those fiberglass repair kits instead of epoxy?"
Honestly, I've given fiberglass kits a shot before, and they're not much better in my experience. Sure, they hold up a bit longer than epoxy, but eventually the cracks creep back in. Porcelain sinks just don't seem to play nice with DIY fixes long-term. I'd say bite the bullet and go pro or replace it outright—saves you headaches down the road. Learned that lesson after patching the same sink twice in six months...
I've seen fiberglass kits hold up okay on tubs or showers, but sinks are a different beast. Porcelain just doesn't flex, and any slight movement or temp change seems to reopen cracks eventually.
"Porcelain sinks just don't seem to play nice with DIY fixes long-term."
Exactly this. Curious though, is your sink undermount or drop-in? I've noticed undermounts tend to crack again faster because of countertop stress...
Mine's an undermount, and you're spot on about countertop stress. Tried the fiberglass kit route myself—looked great for about two months, then the dreaded crack returned. Wonder if anyone's had luck reinforcing from underneath somehow...?
Had the same issue in a rental property last year. Reinforcing from underneath with epoxy and metal brackets worked pretty well—ugly as sin underneath, but tenants don't usually crawl under sinks to judge aesthetics... yet. Worth a shot if you're handy.
