I have just put a new basin in my en-suite. Then I dropped something in it and now it has a very fine crack on the inside. Can I repaire with sealant? Would it work?
If you Vee the crack out on underside all way around with stone cutting disc and seal with silicone, it would probably work .. but it could get worse and show as dirt gets in it .. then leak. Best to get another and careful of the tap spanner next time!
