Grout Enhancing floor tile grout

[Italy]

Was just going to post about the same scenario, I've got about 80 metres to do and was hoping not to have to re grout, presumably the mapei only works with mapei grout, as this was done with ardex fresh snowdrop, any other recommendations out there, cheers matt

mapei fugafresca, it works with all grout, cement-based.

Me too. I'd take the old stuff out with a multi tool and re-grout then seal.

Can't think of a worse job in tiling then of course there is risk to chipping edge of tile .
