Sandstone in stone conservation
May 12, 2021
1. Do not use non-neutral detergent indiscriminately
In order to seek quick cleaning effect, general cleaning contains acid and alkali, so if the use of unknown ingredients for a long time cleaning agent, will make the stone surface gloss lost, and because of non-neutral agent residue is the main cause of stone lesions in the future.Sandstone with its own characteristics in stone conservation five 'not'.
2. Do not cover carpets and sundries for a long time
In order to keep the stone breathing smoothly, we should avoid covering the carpet and debris on the stone surface for a long time, otherwise the moisture under the stone can not volatilize through the stone pores.Stone material can because moisture is overweight, water content heighten and produce annoying stone material pathological change problem if you must lay carpet, pile buy sundry, do not forget to want to often change to want to maintain clean clean thoroughly please.
3. Do not flush directly with water
Natural stone, like natural wood, is a kind of porous material that can breathe, so it is easy to absorb water or invade pollution through water dissolution.Stone if absorb too much water and pollution, will inevitably cause a variety of stone lesions, such as: crack, weathering, falling off, floating, spit yellow, water spots, rust spots, Bai Hua, fog surface and other annoying problems.Therefore, stone should avoid washing with water or washing the surface of stone with a wet mop.
4. Do not touch non-neutral objects
All stones are afraid of acid and alkali.For example: acid often caused in granite pyrite oxidation and spit yellow phenomenon, acid will decompose the calcium carbonate contained in the marble, resulting in surface erosion, alkali will also erode granite feldspar and quartz silicide crystallization of the grain boundary caused by the phenomenon of grain stripping.Therefore non - neutral articles are the cause of the destruction of the stone mirror.
5. Do not use wax at will
Wax types on the market, there are waterborne wax, touch fatty acid wax, oily wax, acrylic wax and so on.These waxes basically contain acid and base substances.It will not only block the pores of stone breathing, but also be stained with dirt and dust to form wax scale, resulting in yellowing phenomenon on the stone surface.If wax is needed in places with high frequency of pedestrians and goods circulation, you must consult a professional maintenance company to instruct you to use wax and maintain.
