Grout colourant

[Rustytrowel]

Hi i have been asked twice recently about regrouting a bathroom, both in ok condition so was considering grout colourant.
A few questions:
How long does it to take to clean and do an average bathroom?
Also if their is cracked or missing grout to patch anywhere how long after patching the area till i could recolour.
Thanks

Use fast setting grout. Try fuga fresca grout re-colour , nice to use and extremely quick and easy to clean up. Done in a day easily.
