Post-cleaning Conservation Of Natural Stone
May 21, 2018

After the deep processing, mining, transportation and environmental factors caused by the pollution of natural stone will produce a lot of lesions, need to be cleaned and polished to restore its value and appearance.

       1, can not contact strong acidic and alkalinity materials

       For example, acid often causes oxidation of the pyritic mineral in granite and yellowing occurs (iron is oxidized to trivalent iron). Acid breaks down the calcium carbonate contained in the marble and converts it into calcium bicarbonate, causing the surface to be Erosion state; alkali can also erode the feldspar in granite and the grain boundary of quartz telluride crystals cause grain exfoliation. Therefore, acid and alkali materials are the original fierce damage to the stone mirror.

2, can not be waxed

       There are a wide variety of waxes on the market, including aqueous wax, stearic acid wax, oily wax, acrylic wax, and the like. These waxes are based on acid and alkali materials. Not only will it block the capillary pores that the stone breathes, but it will also be stained with dirt to form wax scales, causing yellowing on the surface of the stone. However, if it is necessary to wax wax on occasions where the frequency of pedestrians and goods is extremely high, it is necessary to consult professional support companies for waxing and maintenance.

3, can not use non-neutral clean agent

       For the sake of quickness and cleanliness, the general cleansing agent contains acidity and alkalinity. Therefore, if the cleansing agent with unknown ingredients is applied for a long time, the glossiness of the stone surface will be lost, and the non-neutral agent residue is also the main cause of the stone disease in the future.

4, can not be long covered carpet, debris

       In order to adhere to smooth breathing of the stone, it is necessary to avoid covering the carpet and sundries on the surface of the stone for a long time. Otherwise, moisture under the stone cannot be evaporated through the capillary pores of the stone. Stones will suffer from an annoying stone disease due to excessive humidity and increased water content. If you must lay carpets and pile up debris, please do not forget to change them.
