Stone Care: Effective Prevention of Efflorescence and Water Seepage

The widespread use of stone in many squares and public spaces brings dual advantages of aesthetics and durability. However, the maintenance issues of stone also come with it, especially the phenomena of efflorescence and water seepage, which not only affect the appearance but may also shorten the service life of the stone. This article will explore how to effectively prevent these common problems through correct installation and care measures.

Six-Side Protection of Stone: Protecting the stone on all six sides before installation is the first step in preventing efflorescence and water seepage. This process involves sealing all surfaces of the stone to reduce the intrusion of moisture and pollutants. When using oil-based protective agents, it is particularly necessary to apply a waterproof back glue on the back of the stone, which helps to enhance the adhesion between the stone and the cement, preventing issues related to loose adhesion.

Choosing the Right Cement: When laying stone, it is best to choose low-alkali cement. Low-alkali cement contains fewer alkaline substances, which helps reduce the risk of efflorescence by minimizing the alkaline substances that react with the stone. In addition, low-alkali cement usually has better durability and stability, which is crucial for maintaining the stone's appearance and performance over the long term.

Post-Installation Care: After the installation is complete, it is not advisable to rush to clean the joints. The correct approach is to wait for a few days to allow the moisture in the cement to evaporate from the gaps. This step is crucial for preventing water seepage, as the evaporation of moisture reduces the internal humidity of the stone. After the moisture has evaporated, fill the joints with fine sand and dry cement powder, which not only provides an additional layer of protection but also enhances the overall aesthetics of the stone.

In summary, by taking appropriate preventive measures, such as six-side protection, choosing the right cement, and proper post-installation care, the risk of efflorescence and water seepage in stone can be significantly reduced. These simple steps not only improve the appearance of the stone but also extend its service life, ensuring the lasting beauty of squares and other public spaces.
