Grout

[Guest2006]

Some of the grout between the tiles at the end of my bath and inbetween the wall tiles around the shower has 'diasappeared' - ie is no longer flush with the tiel surface

Can I just grout over the gap or do I need to remove the remaining grout and start all over ?

are the tiles loose or the backing moving?

if yes you need to fix this fault 1st then regrout with a part flex water resistant grout

as far as i can tel the tiles aren't moving..... they lay flat and used to have a couple of shampoo bottles stood on them - but not had this for about a year now.
not all the grout areas have 'reduced' just some
