Different stones have different maintenance priorities. The natural stone building materials on the market are roughly divided into two series, marble and granite. Although from the geological formation conditions and chemical organization point of view, this classification method is slightly inappropriate and can not really match the characteristics of the stone, but in the stone maintenance, the basic properties considered can still be considered in accordance with this classification The preliminary basis for the applicability of its maintenance method. For different stone properties, different maintenance methods and maintenance frequencies should be properly selected. All in all, the main considerations for stone care should be to understand the properties of the stone from all possible sources of information and to list the factors that the installation site may infringe on this vulnerability and to look for possible maintenance methods to strengthen the resistance of the stone. Sex or reduce the possibility of rapid deterioration in order to achieve the desired effect of stone maintenance.
