Two-Trowels

We have just finished a 23m floor done in 300x300 grey rocktop porcelain from Johnsons Kerastar 517 Granite Rocktop 297x297x8.3mm and we had a terrible time with the grouting with it being a right bugger to clean off but we did manage to clean them up eventually with a lot of hard work.
The grout (supplied by main contractor) was Dunlop flexible floor and wall tile grout in charcoal, it's a CG2 grout and was like wet sand mixed with molasses that seemed to weld itself to the tile as soon as it was applied - we had used the same in white for the walls on ceramics and that seemed ok.
Should the tiles have been sealed or something first or was it most likely the sticky grout that caused the problem?
