Maintenance Skills Of Rough Stone Surface

Generally speaking, the pores or micro cracks on the surface of the roughened stone will become more obvious. In this situation, the absorption and adhesion of foreign substances will be easier for the stone, so it is easy to be contaminated and cause disease. In addition, due to the increased water absorption of the stone surface, the phenomenon of moisture accumulation inside and outside the stone is more common, such as: internal stress caused by thermal expansion and contraction during climate change, or the breeding of bryophytes to invade the stone and cause extrusion stress Or release biological acid to attack the stone. Based on the above, we know that the rough surface stone should be cured. Only the curing agent can easily cause the rough surface stone to have the effect of deepening the color. Therefore, the actual use test should be performed before use to prevent the color change after curing. effect.
