How to Fix White Stains on Exterior Tiles of Self-Built Houses (Part 2)? ✨

🏠 If the exterior tiles of your self-built house are showing "white stains," it’s not just an eyesore but also a potential safety hazard! Upon investigation, we found that this issue often arises due to poor drainage on the rooftop or insufficient waterproofing measures, which leads to water seeping into the walls. The water carries alkaline substances (calcium hydroxide) from the cement. When exposed to carbon dioxide in the air, it forms hardened calcium carbonate, commonly known as "efflorescence" or "white stains."

Consequences of White Stains:
1️⃣ Aesthetic Issues: The white streaks on the wall surface are highly noticeable and ruin the overall appearance of the building.
2️⃣ Safety Risks: Prolonged water seepage can cause hollowing, increasing the likelihood of tiles falling off ⚠️.

Solutions:
✅ Remove Existing Efflorescence: Use an oxalic acid solution to clean the white stains on the wall and restore its clean appearance.
✅ Redo Rooftop Waterproofing: Strengthen the drainage system to prevent water accumulation and thoroughly address waterproofing to eliminate the root cause.
✅ Use Hanshi 130 Anti-Efflorescence Additive: During tile reinstallation, follow the manufacturer’s standard procedure to prepare the cement-sand mixture. Hanshi 130 effectively locks in alkaline substances in the cement, preventing white stains (efflorescence) from reappearing and avoiding hollowing issues. This ensures a durable, long-lasting exterior! 🌟

✨ Pro Tip: Focus on construction details and choose the right waterproofing and tiling materials to solve the problem at its root, enhancing the durability and safety of your building!

Takeaway:
Don’t overlook the issue of white stains on exterior walls. With the right solutions, your self-built house can look refreshed and safe for years to come!
