1. The contamination should be removed immediately

所有人造砂巖均具有天然毛細孔，污染源(油、茶水、咖啡、可樂、醬油、墨汁等)會很容易順著毛細孔滲透到人造砂巖內部，形成令人討厭的污漬。因此一定要選擇優良品質的石材專用防護劑施作在石材上，防止污染源污染石材。要知道所有防護劑均不可能百分百長期阻絕污染，所以一旦有污染源倒在石材上一定要立即清楚，以防止滲入百材毛細孔內。

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、要常保持通風干燥

2. Always keep ventilated and dry

石材怕環境濕度太大。水氣會對石材產生水化，水解及碳酸作用，產生水斑，白化、風化、剝蝕、銹黃等各種病變，摧殘石材。因此石材安裝出口處要常保持通風干燥。

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、要定期施作防護處理

3. Protective treatment shall be carried out regularly

要長保石材壽命，阻絕水和污染源的滲透，一定要定期(視石材種類及防護劑品質較好是1-3年做1-2次處理)施作防護處理。防護劑的品質一定要特別注意。施作后一定要能維持石材的透氣性及防水性、防污性。決不可使用來路不明的防護劑，以免不但達不到防護效果，反而增加了石材保養的困擾。

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.、不可接觸非中性物品

4. Do not touch non neutral articles

所有人造砂巖石材均怕酸堿。例如：酸常造成花崗石中硫鐵礦物氧化而產生吐黃現象，酸會分解大理石中所含的碳酸鈣，造成表面被侵蝕狀況，堿也會侵蝕花崗石中長石及石英矽化物結晶之晶界造成晶粒剝離的現象。因此非中性物品乃破壞石材鏡面之原因。

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、不可隨意上臘

5. Do not wax at will

市場上的臘種類凡多，有水性臘、感觸脂酸臘、油性臘、亞克力臘等等。這些臘基本上都含酸堿物質。不但會堵塞人造砂巖石材呼吸的毛細孔，還會沾上污塵形成臘垢，造成石材表面產生黃化現象。倘若行人及貨物流通頻率極高的場所必須上臘時，則必須請都保養公司指導用臘及保養。

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.
