Terrazzo is also a construction method, including two other variations – pebble wash and graveling.
Terrazzo is often used as a floor finish. First, the bronze strips are laid on the ground. The mix of crushed and powdered stones with cement and water is poured over the ground. After drying, the cement surface is sanded with or without water until the stones are exposed, and then waxed and polished.
Graveling involves the use of natural or manmade stones. They are mixed evenly with cement and used as floor or wall finishes. The cement is wiped with a sponge before it is completely dry to expose the stones.
Pebble wash is a wall finish that consists of a mix of cement with powdered and finely crushed stones. After drying for a period of time, the wall finish is sprayed with water to wash off parts of the cement and expose the thick and coarse stone surface.
The Construction Material
Raw materials for terrazzo include crushed and powdered stones, white cement, bronze strips and cement coloring. Some bronze strips come in precast designs such as cranes and butterflies.
The cement coloring includes 7 colors – black, charcoal gray, red, orange, yellow, green and blue.
Geometric designs were often used as a floor finish under arcades or for traditional houses in Taiwan.
