Who mixes grout colours

[jonnyc]

I've been mixing ardex c2 coloured grouts together ,mixed dry by strict proportions for twenty odd years to give me multiple shades to match stones we fix.c2 beige is now being discontinued which scuppers me getting various good shades of colour.
never had a problem though and then been doing the same with ardex fs grouts without problem either provided that in case of fs I mix dry,add water and dry as fs dry mixed is not always same after mixed with water and dried.
but now doing more porcelain I am finding the fs takes too long to go off and more difficult to get a flush joint even double grouting.
so I've been thinking of mixing Mapei ultra colour grouts to get multiple shade variations but Mapei would not guarantee even colour whereas ardex could.
anyone mix Mapei colours or any other grout make that is fast set and guaranteed to be even in colour.

have you tested the mapei? I cant see why there would be a problem as surely as long as it is the exact type of grout just a different colour it would only be the pigment that is any different?

Cant remember who it was but they were mixing 2 shades of Mapei grey to get the shade they required. I dont remember them saying that they had any issues.

I've mixed colours, same brand, without any problems to get a bespoke colour, As long as they all have the same "C" classification on the same brand I don't see a problem.

Think you mean you dyed the grey grout black don't you not the adhesive.
what did you use for dye.
i have never trusted mortar colour dyes since I did a job many many years ago and ruined a quarry floor with black sand cement grout.

Doug I can't see the problem either Doug but the Mapei tech guy said he thought dodgy. Maybe just covering himself.

maybe he used to work at Topps, or never even grouted a tile in his time. Polymers are gonna be the same, and I'm sure pigment will be the same, in ratios.

Why dye grey adhesive black?
is this in case any squeezes through joint and you don't have to clean out if using black grout.
