My builder says epoxy grout too "inflexible"?!

I just Epoxy grouted the ensuite i have been doing. It was a custom colour so i dry mixed it all up first .Then did a wall a time . Yes ..Its hard work . And you need to be quick. But with all the right tools and plenty of buckets of water etc.I had it all done in a day and nicely cleaned off. No "Dust" residue etc . Looks lovely . Internal corners been "Colour matched " silicon tomorrow.

What epoxy was that then . I don't understand dry mixing it as I have only seen liquid epoxy

I meant I did small sample mixs and then dried them until i found the correct shade the client wanted !
