Methods to Prevent White Efflorescence on Wulian Stone

Five Lotus Stone, due to its absorbent nature, is prone to the formation of efflorescence, which can affect the aesthetic appeal of the stone. Excessive water and alkaline metal ions are the primary causes of efflorescence. Therefore, preventing the accumulation of excessive water and alkaline metal ions can help prevent the formation of efflorescence. Next, let's explore the methods for preventing efflorescence in Five Lotus Stone.

Five-Lotus marble should undergo a protective treatment before installation to prevent excessive moisture absorption. This measure is to stop water from penetrating the marble from the front or seeping into the cement mortar beneath the marble from groundwater sources, thereby avoiding the infiltration of alkaline metal ions from the mortar into the marble, which can cause efflorescence.

2. Selecting the appropriate grout material for the Wuhualian stone and applying it using the correct construction methods ensures high-quality grouting and prevents the occurrence of efflorescence at the grout joints.

When mixing cement mortar, using water-cement ratio or adding water-reducing agent to reduce excessive water can prevent the occurrence of white efflorescence.

Adding a waterproofing agent to cement mortar can prevent the dissolution and leaching of metal ions from the surface of the five lotus stone, thus avoiding the formation of white efflorescence.

5. Choose non-polluted sand, such as avoiding sea sand with high levels of calcium, magnesium, and sodium ions, and avoid using groundwater rich in minerals as mixing water to reduce the source of metal ions and minimize the occurrence of efflorescence.
