1. The contamination should be removed immediately

所有人造砂岩均具有天然毛细孔，污染源(油、茶水、咖啡、可乐、酱油、墨汁等)会很容易顺着毛细孔渗透到人造砂岩内部，形成令人讨厌的污渍。因此一定要选择优良品质的石材专用防护剂施作在石材上，防止污染源污染石材。要知道所有防护剂均不可能百分百长期阻绝污染，所以一旦有污染源倒在石材上一定要立即清楚，以防止渗入百材毛细孔内。

All artificial sandstones have natural pores, and pollution sources (oil, tea, coffee, coke, soy sauce, ink, etc.) will easily penetrate into the artificial sandstone along the pores to form annoying stains. Therefore, we must choose high-quality stone special protective agent to be applied on the stone to prevent the pollution source from polluting the stone. We should know that all protective agents can not prevent pollution 100% for a long time, so once a pollution source falls on the stone, we must be clear immediately to prevent it from penetrating into the pores of 100 materials.

2、要常保持通风干燥

2. Always keep ventilated and dry

石材怕环境湿度太大。水气会对石材产生水化，水解及碳酸作用，产生水斑，白化、风化、剥蚀、锈黄等各种病变，摧残石材。因此石材安装出口处要常保持通风干燥。

Stone is afraid of too much environmental humidity. Water vapor will hydrate, hydrolyze and carbonate the stone, produce water spots, albinism, weathering, denudation, rust yellow and other diseases, and destroy the stone. Therefore, the stone installation outlet should always be ventilated and dry.

3、要定期施作防护处理

3. Protective treatment shall be carried out regularly

要长保石材寿命，阻绝水和污染源的渗透，一定要定期(视石材种类及防护剂品质较好是1-3年做1-2次处理)施作防护处理。防护剂的品质一定要特别注意。施作后一定要能维持石材的透气性及防水性、防污性。决不可使用来路不明的防护剂，以免不但达不到防护效果，反而增加了石材保养的困扰。

In order to prolong the service life of stone and prevent the penetration of water and pollution sources, protective treatment must be carried out regularly (1-2 times in 1-3 years depending on the type of stone and the quality of protective agent). Special attention must be paid to the quality of protective agents. After construction, the permeability, waterproof and antifouling of stone must be maintained. Never use the protective agent with unknown origin, so as not to achieve the protective effect, but increase the trouble of stone maintenance.

4.、不可接触非中性物品

4. Do not touch non neutral articles

所有人造砂岩石材均怕酸碱。例如：酸常造成花岗石中硫铁矿物氧化而产生吐黄现象，酸会分解大理石中所含的碳酸钙，造成表面被侵蚀状况，碱也会侵蚀花岗石中长石及石英矽化物结晶之晶界造成晶粒剥离的现象。因此非中性物品乃破坏石材镜面之原因。

All artificial sandstone stones are afraid of acid and alkali. For example, acid often causes the oxidation of sulfur and iron minerals in granite to produce yellowing. Acid will decompose the calcium carbonate contained in marble, resulting in surface erosion. Alkali will also erode the grain boundaries of feldspar and quartz silicide crystals in granite, resulting in grain peeling. Therefore, non neutral objects are the reason for destroying the stone mirror.

5、不可随意上腊

5. Do not wax at will

市场上的腊种类凡多，有水性腊、感触脂酸腊、油性腊、亚克力腊等等。这些腊基本上都含酸碱物质。不但会堵塞人造砂岩石材呼吸的毛细孔，还会沾上污尘形成腊垢，造成石材表面产生黄化现象。倘若行人及货物流通频率极高的场所必须上腊时，则必须请都保养公司指导用腊及保养。

There are many kinds of wax on the market, including water-based wax, touch fatty acid wax, oily wax, acrylic wax and so on. These waxes basically contain acid and alkali substances. It will not only block the pores of artificial sandstone stone breathing, but also be stained with dirt to form wax scale, resulting in yellowing on the stone surface. If waxing is necessary in places with high frequency of pedestrian and goods circulation, professional maintenance companies must be invited to guide the use and maintenance of waxing.
