Its not too hard tbh it all depends on where the crack / area of repair is the repair kits are pretty much straight forward there are some very helpful video's and tutorials on YouTube(ye it sounds stupid but YouTube is actually one of the best sites on the internet IMO) which is what i always refer to if I’m in need of emergency help at no cost just search Ceramic sink repair on YouTube comes up with many results. your local hardware store would be best place to go and acquire a kit the people in there could also point you in the right direction if YouTube is no help, sorry couldn’t be of any more assistance
