This kind of wall plate, there is this phenomenon, with the method of protective treatment and filling glue, can not be cured.

Water-based, oily protective agent, can reduce the stone water absorption rate of more than 90%, but less than 100%.Even if done to protect, in a long-term wet environment, stone or water absorption ability.The dissolved salt also has a strong destructive effect on the molecular chain of the protective agent after curing.Therefore, the protection effect is always with the growth of time and gradually decreased.

The filling glue only patched up the surface pits, but did not have any effect on the change of internal salt content.Other places will continue to collapse, and the glue may fall off.
