Mapei Keracolor GG

[Qwerty]

I've soon to grout up a newly laid terracotta kitchen floor and was considering using Mapei Keracolor GG instead of Ultracolour plus which I usually use.
I'm going to phone tech support to enquire about use on a heated floor. Literature only mentions that the flexibility complies with requirements in a CG2 grout!?

Anybody else ever used Keracolor GG? If so, thoughts on it please

Cheers. Got that already. Doesn't tell you much to be honest unlike the Ultracolour plus PDF that says everything in detail.
