How are Terrazzo Floors Made? How are Terrazzo Floors Made?
People have been using terrazzo floors since the 16th century; artisans laid this flooring in Venetian villas. The name comes for the Italian word for terrace. Terrazzo is a perfect flooring choice because of its classic look, longevity, durability and low maintenance cost.
Terrazzo floors need 3 layers of materials. Terrazzo workers first create a concrete foundation that’s solid and level about 3 to 4 inches deep. Once the forms are taken out from the foundation, they add 1 inch layer of sandy. Before the layer sets, the workers partly set in metal divider strips on the concrete; this divides the area where there is to be a color change in the terrazzo; thus beautiful floor designs may be created.
For the last layer, mix and place a fine marble, granite or glass chips combination in cement; the cement may also be color-pigment for a particular panel created by the metal strips. Terrazzo workers use a variety of colors of chips into each panel while the mixture is still wet. To achieve a smooth and uniform surface, it needs to be hand-troweled. A lightweight roller is the used to smooth out the whole surface.
Once the terrazzo is completely dry, a terrazzo grinder is used to grind it. Slight dents caused by the grinding are filled with grout. The dry surface is then cleaned, polished and sealed for a shiny finish.
Terrazzo floors can be used indoors or outdoors because of its durability. It is even perfect for high traffic areas such as hallways and lobbies. If you want a reasonably-priced, durable substitute to stone or ceramic tiles, then terrazzo is your answer.
