However, water stains may not disappear under high water temperature conditions. Long-term storage, each stained material (except liquid) itself does not It will have an effect on the stone. Only when the material meets the water, the chemical change dyeing will be formed immediately. Therefore, it can be concluded that the water is the biggest enemy of the stone, and only the pores of the stone can be blocked to solve the problem.

When the crystal gradually becomes larger, the surface of the stone will pop open and crystals will be precipitated, such as golden flower beige, Taiwan green. , gold wire beige, Egyptian beige and so on.
Stone protection is to "prevent the infiltration of water and allow the water to exhale." “Prevention is better than cureâ€, this famous saying is most suitable for stone. The stone protectant provides comprehensive protection for the stone against different characteristics, resisting penetration such as moisture, stains and oil stains, and also preventing minerals. The salt is taken out of the stone, and white rust or rust stains are produced.
