external grout paint?

[joeogorman47]

I've got grey grout on external tiles. Is there a grout paint that will allow me to change this from grey to black?

Mapei Fuga Fresca or Aquamix colourant...but not sure about outside use ?

I would have thought aqua mix would be ok for exterior use. Once its applied its pretty permanent.

Aqua mix grout colourant is fine for outside use..
