Traditional terrazzo is made of cement and marble with extra marble chips on the surface. The cement portion is porous and quickly absorbs stains. A more modern form, made with synthetic resins such as urethane or epoxy as the \"binder\", in place of cement do not stain as readily. A penetrating sealer should be applied to new terrazzo floors to seal the pores in the cement and thus retard stains absorption. Resealing may be needed occasionally.
