The Maintenance of Terrazzo

Although durable, terrazzo can be a bit complicated to maintain when compared to other hard floor options. Make sure you know how to clean and burnish these floors before you take on the job of caring for one.

The reason why terrazzo is as bright as a mirror and crystal clear is mainly because a layer of glassy film is formed on the surface of the terrazzo after mechanical processing. This film not only has a mirror luster, but also can transparently show the internal structure of the stone, which is the pattern that people observe.

To restore the beauty of weathered and abraded terrazzo, the key is to reform a vitreous film on the surface of the terrazzo. The weathered and abraded aging layer on the surface of the terrazzo is shaved to expose the fresh layer, and then a special mechanical method produces an extremely complex effect on the surface of the terrazzo to form a new vitreous film, thereby restoring the natural and beautiful decorative effect of the terrazzo. The whole process includes multiple procedures without the use of chemical.

Make the rough and dirty terrazzo become smooth and bright and achieve a mirror effect. This process has a low cost of refurbishment. No pollution, no dust, no muddy water splashing or noise during construction, such as shopping malls, hotels construction can be carried out while operating. It can also change the traditional floor construction technology, for example, the floor can be paved with a rough board or squeezed and then polished. Not only can the cost be reduced, but also the splicing joints in the construction can be eliminated.
