Maintenance factors:
1. After we analyze the roughened stone, the pores or micro cracks on the surface will become more obvious.
2. It is easier for the stone to absorb and adhere to foreign substances, so it is very easy to be contaminated and cause disease.
3. 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 bryophytes invade the inside of the stone and cause extrusion stress Or release biological acid to attack the stone.
Method of maintenance:
Only the curing agent can easily cause the rough surface of the stone to have the effect of darkening the color, so the actual use test should be carried out before use to prevent the adverse effect of the color change after curing.
Let's learn about it this time, and continue to learn more about it next time.
