Hi @fergusonbj,
A warm welcome to the Bunnings Workshop community and thank you for your question.
Without seeing the chip in the floor tile it is hard to give you a definitive answer to your question. If you have a photo you can upload, this would certainly help. Let me know if you need a hand uploading images, I'm happy to help if required.
Have a look at the following discussions which offer a variety of solutions to similar issues.
If you have a spare tile, there is also How To Replace a Broken Floor Tile which is certainly worth a read.
Let me know if these discussions don't answer your questions. Once you've uploaded a photo or and added some further details, I'm happy to assist further.
Jacob
