Terrazzo consists of marble or granite chips set in a binder (typically Portland cement or epoxy) and ground smooth after curing. This premium flooring provides durability and aesthetic appeal. Base preparation must ensure level, stable substrate. Substrate cracks cause terrazzo cracks. Proper base design prevents movement. Metal divider strips (zinc, brass, or stainless steel) separate terrazzo sections controlling crack location. Strips are placed in straight patterns. Marble and stone chips are selected for color and size. Binder is selected for durability and performance. Portland cement terrazzo is economical and durable. Epoxy terrazzo provides better color consistency and performance. Polyester or polyurethane binders offer additional options. Mixing combines binder, chips, and pigments. Proper mixing ensures even color distribution. Installation is troweled and smoothed. Timing of grinding is critical; too early and chips pull out; too late and grinding is difficult. Grinding with progressively finer stones creates smooth finish. Polishing with diamond pads creates glossy finish. Sealing protects the surface. Terrazzo is porous and absorbs stains if unsealed. Sealers prevent staining and moisture absorption.
