Maintenance knowledge of marble and granite

By Andrew Smith

granite is an igneous rock, the main component is silica, which is characterized by tightly arranged pores and greater hardness. Granite is resistant to acid and alkali, weathering, and is generally used for outdoor exterior wall decoration. Because granite has a relatively high density, it has low water absorption, so you should use a protective agent with good permeability when protecting it. Usually, it is enough to protect it once. When cleaning and maintaining, use as little water as possible, but even water should be able to dry quickly.

       When granite is cured, it should be pre-treated with a penetrating protective agent. If it is under normal conditions, it can be cleaned with a neutral or weak acid cleaning agent. If there is no obvious dirt on the surface of the dark granite, it is necessary to use a cleaning agent to treat it properly, otherwise it will affect its color effect and cause the surface to become dull.

      The main components of marble are calcite and calcium carbonate, which are characterized by hardness, acid and alkali resistance, and weathering resistance is slightly worse than that of granite, but you must pay special attention to it when curing. Because its pore arrangement is larger than that of granite, its water absorption will be stronger. If the stagnant water stays on the stone surface for too long, it will absorb part of the water, but if it can’t dry out in time, it may cause lesions, so cleaning up will be more troublesome.

       If juice, coffee and other liquids with slight acidity and alkalinity can cause damage to the marble, if there is any spillage, you need to wipe it off immediately, and then rinse it with water. For example, some white marbles should be paid special attention. Try to use neutral detergent for daily cleaning.

      On the ground where people frequently walk, marble floor tiles need to be protected with protective agents. Before the marble is put into use, it is necessary to use a permeable waterproof and oil-proof protective agent for pre-protection, and it is best to protect it twice, so that the effect is better.

      If you encounter a dark Cartier gray marble with obvious scratches, the color of the scratches is white, and you need to be extra careful and careful to protect and maintain. If necessary, choose a professional stone maintenance company to polish.
