W/o seeing the floor - no guarantees, YMMV, all caveats apply, and all that crap. Probably work fine, but I haven't done so. I would take into consideration the condition and age of the tile, incl. the subfloor condition (under the mortar) and whether it is wood or slab.
The epoxy rock flooring has gotten somewhat popular on the west coast for interior floors but remember, it's not maintenance free. It has to be cleaned regularly and should be done once a year by a rug cleaning outfit as it's somewhat porous and attracts dirt and believe it or not, particles of dead skin from those who go barefoot much, which gives the place a gymnasium smell.
