Hi,
I found some slight cracking in some of the wall tiles (not near shower - up by window) which i suspect is due to movement - tiles are still firm. Pictures attached although these are magnified.
Following advice from local DIY shop i attempted to fill in the cracks and re-cover with new bathroom anti mould tile grout (pictured).
Is this the best way of doing this going forward as i suspect years down the line movement will happen again. Is there a better filler.
Thanks
