Surface crack in bathroom sink
 

I discovered a surface crack in our bathroom sink, not leaking (yet), but I wonder if there is a surface-applied product that will seal the crack before it gets any worse. The sink is "white", so a clear product would probably work the best. Thanks in advance.

Might be a good idea to start looking at replacement sink. And while at it. Replacement faucet.

Is there some kind of Crazy Glue that will hold the sink together? Doubt it.

A picture would help.

Liquid silicone is a product I have used.

If you go into this knowing that a new sink is likely to be required soon then you have little to lose.

I assume you're talking about a ceramic type sink, maybe porcelain?
I'm pretty sure you can get ceramic crack repair kits at most hardware stores. I think they're basically an epoxy application.
Make sure it's really on the surface only and monitor it to see if it propagates.
Did it happen from an impact?

Cause? Prevention?
 

Any idea what caused the crack? Could it happen again whether you repair or replace?
I had an old "green" bathroom once and a company came in and spray coated all the fixtures. Looked brand new. I don't recall cost, but cheaper than a plumber replacing everything.
