Traditional terrazzo has a huge market in China because of its unique advantages, such as low cost, free color matching and convenient construction. There are as many terrazzo floors as 10 trillion square meters used in various urban and rural buildings in China. However, the traditional construction technology causes the terrazzo floor to be very rough and dirty even before delivery, which brings serious obstacles to daily hygiene and cleaning. However, with the passage of time, we have encountered very prominent problems in practical use: terrazzo weathering, wear, stains and dullness. How to restore the weathered terrazzo to its original beauty is an increasingly urgent problem in the architectural decoration industry. Facing the weathering and abrasion of terrazzo, the only way at home and abroad is to clean the dirt on the stone surface and put a layer of wax on it. This method can protect the new terrazzo surface to a certain extent and delay the natural weathering and abrasion, but for the weathered terrazzo surface, its effect is no different from brushing a layer of varnish on the decayed wood surface, and it can't reproduce the mirror-like effect at all.
Moreover, the wax film formed in this way has poor durability and can only be stored for about a week, so it needs to be cleaned before waxing. Not only the construction is frequent, but also the cost is very high, and the cost of cleaning and waxing per square meter every year is as high as several hundred yuan. Cleaning and waxing is the only expedient measure that cleaning companies can't cope with customers at present, and it can't cure the symptoms, let alone the root cause. The reason why cleaning and waxing is not a real stone floor treatment is that the technical key of terrazzo treatment has not been really solved. The reason why terrazzo is as bright as a mirror and crystal clear is mainly because a glassy film is formed on the surface of terrazzo after mechanical processing. This kind of film not only has mirror luster, but also can transparently show the internal structure level of the stone, that is, the patterns observed by people, and the beautiful aesthetic feeling is here. In order to restore the beautiful beauty of weathered terrazzo, the key is to re-form a glassy film on the surface of terrazzo.
