If you want to repair cracks in a Terrazzo floor, you would have to dismantle the cracked portion but care has to be taken that the base coat should not be disturbed and only the cracked part should be dismantled. After doing that, clean the loose material and then fix the base coat and lay the flooring that best matches the floor. You would have to prepare a mixture using marble chips, water, coloring, mineral content and terrazzo cosmopolitan for placing over the crack.
You see further instructions on preparing the mixture and laying it.
