Why Does Efflorescence Start from the Edges?

🌟 Reasons Efflorescence Begins at the Edges:

1. 💧 Pathways for Moisture Infiltration
   The edges of stone or tiles are in direct contact with cement mortar, and gaps or pores provide entry points for moisture. This moisture dissolves the alkaline components in the cement, forming a saline solution. As the moisture evaporates, salts crystallize at the edges, causing efflorescence.

2. 🍃 Differences in Air Circulation
   The edges allow for better air circulation, leading to faster moisture evaporation. This makes salts more likely to crystallize along the edges. In contrast, the center of the stone or tile retains moisture longer, delaying efflorescence.

3. 🌡 Impact of Temperature Changes
   The edges of the stone have a larger surface area exposed to air, making them more affected by temperature fluctuations. This leads to faster thermal expansion and contraction, which drives moisture and salts toward the edges, causing efflorescence.

✨ Special Reminder: The Role of Hanshi 130 Anti-Efflorescence Additive
Hanshi 130 Anti-Efflorescence Additive can lock the alkaline substances in cement and tile adhesive, effectively preventing efflorescence. When using Hanshi 130 Anti-Efflorescence Additive, it is essential to seal the gaps between stones or tiles with a paste-like mixture, ensuring that the cement alkalinity beneath the leveling layer does not escape. This approach addresses efflorescence from critical areas and ensures optimal performance of Hanshi 130 Anti-Efflorescence Additive.
