White sand beige is deeply loved by architectural designers because of its simplicity and naturalness. But after put into use for a period of time, there will be weathering, black pinholes, pollution and other phenomena, which will affect the decorative effect and image of stone. The reason why this happens is mainly determined by the physical and chemical properties of Baisha beige.
White sand beige: the mineral composition is mainly timely and feldspar, mineral sedimentary rocks containing cuttings, and some slightly metamorphic clastic rocks. Physical properties: density: 2.36g/cm3, water absorption: 3.35%, hardness: 33. As can be seen from these data, white sand has low beige density and high water absorption, which is prone to the above situation. According to its physical and chemical properties, it is not suitable for outdoor use.
How to clean and maintain white sand and beige after these situations?
Firstly, the weathering and pollution on the stone surface are removed. If possible, the surface should be polished and renovated, and the weathering layer and aging layer on the surface should be removed by physical methods to expose a new stone surface.
If conditions do not permit, chemical cleaning method should be used to clean the black pinholes and pollution on the stone surface. Apply granite cleaning agent to the stone surface and let it stand for 8 hours to see the removal effect. If it is not completely cleaned, repeat the second operation until it is cleaned.
Second, in order to prevent the stone from being polluted and weathered again, the stone surface should be protected. When the stone surface is dry, it should be painted with a composite nano-protective agent. After the stone surface is completely absorbed and saturated, it should be painted with a sealed protective agent. After this treatment, the white sand beige stone will not have to worry about surface pollution for two years.
