Stone creates a completely different kind of visual feast in ordinary engineering buildings, and as immediate users of roadside stones, you should pay special attention to their maintenance under normal circumstances. Normally, in the whole process of applying roadside stone, if you feel that it is very hard and not necessarily maintained, then your thoughts are ridiculously wrong. Everyone should also understand that the stone itself has a natural physical water (generally granite absorbs 0.1 - -0.2%). Many Wulianhong stones are very vulnerable to damage due to unscientific deposition, packaging, transportation, and external resources (such as water vapor, precipitation, crude oil, etc.). The maintenance processing process should be selected immediately before the reduction of the smoothness of the stone does not exceed the resilience of the maintenance measures. After the maintenance is carried out, the smoothness response base can achieve the original standard, so that the stone always remains as new for a long time, and is in a relatively ideal application situation.
