hariline crack in tile

[keenbutconfused]

I have a hairline crack in some tiles around my bath. The cracks don't appear to run through to the back of the tile but just in the shiny stuff on top.

I am concerned that these might get discoloured, is there a way of sealing it to avoid water/ mould getting in?

Frankly, the only long term solution is to cut the tile out and replace it.

However, it's not likely to let much into the gap. If you're concerned then you could do worse than to carefully paint the gap with something like nail repairing solution - it's sets really hard, is flexible, durable, and glossy. And cheap, and you can keep doing it however often you have to until you get fed up and cut the tile out and replace it...

How big is the tile ?, What colour are they ?, how do you know how far in it goes ?, How did they appear ? How Many are cracked ?
