How do I epoxy a crack leak in a toilet bowl?

To fix it take a little sand paper to and around the crack before applying. You could actually go to hardware store and get some clear waterproof epoxy to use.

Best advise I could give you is to change the toilet. There is no real fix to cracks in toilets. Even if you put epoxy on it, it will eventually peel off in no time.

Best advise I could give you is to change the toilet And that's the same advice I would give. As I told a asker with the same problem' "China's very brittle and little cracks can grow into big cracks."
My advice? Replace the bowl. Good luck, Tom

Agree with Libran and Tom 100%: cracked china means broken toilet. It may disintegrate under you at any moment. For your safety: don't repair. Replace it.

If you don't have money or time to replace it ASAP, use mighty bond. Make sure the surface is dry first and just put a very thin or tiny drop.

Bottom line! You repair cracked china at your own risk! Good luck, Tom

Save the price of that glue, it won't work. Did you ever try to glue a broken plate, how that work for you?
