Fuga Fresca grout colourant

[On one]

Unfortunately I going to most likely use the above on a wall grouting job that has gone patchy.
(I know I did nowt wrong with the grouting,but it has gone ***s up and it is going to be up to me to sort it out)
Has anyone used Fuga Fresca before.....just looking for any hints or tips....... what dwell time do you give it?......can staining on adjoining surfaces be a problem?
I only ask as the Technical Dept has been as helpful as their local rep in being helpful.....NOT!

Try a light sanding, this happened to me with Mapei UCP grey and worked well.

Unfortunately we are past that stage.....tried it and it didn't work.

Obviously not just on the surface then?

It did work on some small areas but not all.

I used it on some ceramic tiles. Dark grey worked a treat. Very uniform finish. Was a couple of years back now never heard from the customer again.

I used a fresh escape a couple of times
fast if the tiles are not rough,
otherwise the work becomes a bit slower.
in any case, he does his job well.

I’m sure @Mapei UK Marketing can help, if not I think @MissTiler has used it

I think Mr Friday aka @Andy Allen used it a little while ago.

I used it a few times. Works a treat, but you may have to do several coats.
