Terrazzo floor with low cost, shape color controllable, convenient construction, etc., are widely used in public spaces and workshops, warehouses factories, classrooms, etc. However, due to the current construction techniques in use the old method of rough grinding, plus terrazzo kibble after coarse pores, easy to filth, susceptible to wear and a variety of water-based, oil-based stain penetration, resulting in surface weathering stripping, dusting, appear tiny holes and pollution. Regular cleaning wax can not fundamentally solve the problem. Must improve the quality of terrazzo fundamentally make routine maintenance easier. The best approach is to use a mirror finish with stone grinding machine and grinding material number of different numbers of terrazzo coarse, fine, fine three sanding, sealing tiny holes, strengthen internal structure, so that the surface of pharmaceutical compounds with terrazzo reaction to produce hard wearing, high-brightness, water pollution, easy to clean and maintain a dense protective layer of the crystal. Meanwhile highlight terrazzo surface mirror effect. Gloss polished terrazzo refurbished after crystallization, hardness, anti-fouling properties, water absorption can be comparable with marble.
