SpectraLOCK grout Question for the pros

[axa]

I have :
Laticrete SpectraLOCK PRO Premium Epoxy Grout Full Unit Part A & B

But I only have access to the 'regular' SpectraLOCK part C mini grout powder from the local lowes... this is apparently NOT the PRO stuff, or even PREMIUM as far as i read on the package, it just says "SpectraLOCK StainPROOF Grout" in a brown/white quart paper milk carton....

Simple Question, can I use these together in the proper ratios 4 mini to 1 full??
Thanks for the info

The C part is all the same, never changed. The A&B parts are new and improved. Yes, 4 mini's = 1 full
