Toilet floor tile gaps filling - What to use to fill them?

[CRV48 2]

Hi all,

 

My Bathroom toilet tiles are showing sign of gaps, the grout filling seems to have dropped. May I know what material should i use to fill it up with?

Went to DIY shop looking at Selley products and the assistance says that their products there(limited option) are not suitable...

Anyone can advice??? Would appreciate brand of products and where to get these products will help.

 

Many Thanks in advance....

You could try Davco Rejuvenation Grout, saw them selling at Selfix but i'm not sure how much it cost. Be sure to prep the surface well before applying.
