Four taboos of sandstone

Taboo 1: refuse to rinse directly with water

Like natural wood, natural stone is a kind of porous material that can breathe, so it is easy to absorb water or dissolve in water and invade pollution. If the stone absorbs too much water and pollution, it will inevitably cause various stone diseases, such as: cracking, weathering, shedding, floating, yellowing, water spots, rust spots, white flowers, foggy surface and other annoying problems. Therefore, the stone should be avoided to wash with water or wash the surface of the stone with an over-wet mop.

Taboo 2: Do not touch non-neutral items

All stones are afraid of acid and alkali. For example: acid often causes pyrite minerals in granite to oxidize and produce yellowing. Acid will decompose calcium carbonate contained in marble and cause surface erosion. Alkali will also erode granite feldspar and quartz silicification. The grain boundary of the material crystal causes the phenomenon of crystal grain peeling. Therefore, non-neutral items are the cause of damage to the stone mirror.

Taboo 3: You can't go to wax without reason

There are many kinds of wax on the market, including water-based wax, tactile wax, oily wax, acrylic wax and so on. These waxes basically contain acid and alkali substances. Not only will it block the pores of the stone's breathing, but it will also be stained with dust and form wax scale, causing yellowing on the surface of the stone. If wax must be applied to pedestrians and places with a high frequency of goods circulation, you must ask a professional maintenance company to guide wax use and maintenance.

Taboo 4: Do not use the cleaning agents on the market at will

For the quick cleaning effect, the general cleaning contains acid and alkali. Therefore, if the cleaning agent of unknown composition is used for a long time, the surface gloss of the stone will be lost, and the failure of cleaning due to the residue of the cleaning agent is also a cause of stone disease. German Sino cleaning agent will not burn the stone and can effectively clean the stains. For example, SINO-306 stone cleaning agent can directly apply the cleaning agent to the stone surface, which can be covered with plastic wrap. The severely stained area can be cleaned with a brush. The working time is about 5-40 minutes. After completion, rinse thoroughly with clean water. It is recommended to take a protection to prevent re-lesion.
