Tile edges showing after tiling- can anything be done?

[Amber1191]

Hello,

We recently had a family friend who is just about to finish his tiling apprenticeship tile out splashback (paid job).
Unfortunately we have noticed that the tile edges are showing in two areas. Are there any options to rectify this or will we need to pull tiles up and start again? We are happy with the rest of the tile. We wondered if we could add a trim over the top but read it can only be applied before tiling.

Take them off and re-do with trims. 👍

Or paint that tiles biscuit first. Only need tester pot for that small amount. Then if you aren't happy with them painted, pull off and re-do with a trim.
