*Grout falling out*

Asked by Perdi Hay from London:	In my shower the grout is falling out and behind it is black have re grouted it but same thing happens this problem is on the walls of the shower

TileProf says:	Hi perdi. Sounds like you need a flexible waterproof grout, you could try Mapei Ultra-colour http://www.tiledoctor.co.uk/Mapei-Grout-Shop.asp#Ultracolour, rake out all the bad stuff and apply this instead, if you have an uneven colour you can always Grout colour the whole lot so it all belnds in.
