Inconsistent grout colour

[Dave]

This will be polymers from washing down , dirty water clings to the joints when washing down and not changing water sufficiently.... It happens more so when washing down to early and not letting the grout firm up...

Thanks for all your replies. Is there a cleaner to remove the polymers or should i just go straight to the stain. thinking of using the Mapei version as it will match the Silicon.

grout stain from trade tiler is a gr8 product, used once and had good results

maybe im just lucky , but iv'e never had probs with grouts drying diff colour . and cant think why it should , i mix the grout the way i like it ,

Same here. Ardex FS is excellent stuff too.
