In general, the roughened stone has a large pore or micro-crack on the surface. In this way, the stone becomes more susceptible to foreign matter and is therefore more susceptible to contamination and lesions.
Due to the increased water absorption of the stone surface, the phenomenon of water accumulation inside and outside the stone is more common, such as: internal stress causing thermal expansion and contraction during climate change, or intrusion of mossy plants into the interior of the stone to cause crushing stress or release. Bio-acid attack on stone.
In comparison, rough stone should be cured, so as to maintain the beauty of the stone. However, when the coarse cloth stone is used for curing, the curing agent is very likely to cause the rough surface of the stone to have a deeper color effect. Therefore, the actual use test should be carried out before use, so as not to cause the adverse effect of the color change after curing.
