I SAW A TREATMENT FOR A CONCRETE GARAGE FLOOR ON ONE OF THE HOME IMPROVEMENT SHOWS. SORRY, I DON'T REMEMBER IF IT WAS THIS ONE OR NOT. AN ADHESIVE WAS ROLLED ON AND THEN MULIT COLORED FINE GRAVEL WAS SPREAD OVER THE FLOOR. AFTER IT HAD SET, IT WAS VACUUMED AND THEN POLISHED. DOES ANY ONE KNOW ABOUT THIS PROCESS? I HAVE A GLAZED TERRA COTTA TILE FLOOR IN THE LOBBY OF AN APARTMENT BUILDING, THAT I WOULD LIKE TO DO SOMETHING WITH. I DON'T WANT TO TEAR IT OUT. I WAS THINKING OF SOMETHING LIKE THIS. ANY OTHER SUGGESTIONS?
