Even 20-Year Experts Get This Wrong: It’s Not the Cement
Created on 04.02
On many job sites, when cracking appears,
the first reaction is:
“Is there something wrong with the cement?”
But based on real project analysis,
over 90% of cracking issues are caused by formulation instability — not the cement itself.
⚠️ What’s the real problem?
Self-leveling is not just about flowability —
it is a system highly sensitive to structure formation and hydration dynamics.
Cracking usually comes from three key imbalances:
1️⃣ Water imbalance
If water evaporates too fast or retention is insufficient,
cement hydration becomes incomplete.
👉 The structure hasn’t formed yet, but shrinkage already starts.
2️⃣ Shrinkage stress failure
Shrinkage is inevitable during curing.
If the system lacks flexibility or stress-relief capability,
👉 the only way to release stress is cracking.
3️⃣ Conflict between flow and structure
Many formulations push for better flow
at the cost of structural integrity.
👉 The result: easy application, poor long-term performance.
⚠️ Why do some projects perform well with the same materials?
Because stability doesn’t come from a single component —
it comes from system compatibility.
Temperature, humidity, and substrate absorption
all affect moisture movement.
Without adaptability,
even good materials can fail.
👉 Failure is not random — it’s a lack of system tolerance.
✅ How to actually reduce cracking?
Crack control is not about improving one parameter —
it requires system-level optimization:
✔ Improve water retention to ensure proper hydration
✔ Balance flowability and structural integrity
✔ Introduce flexibility to absorb shrinkage stress
✔ Enhance adaptability to varying site conditions
👉 The goal is not “stronger” — but more stable.
🤝 Our approach
We focus on long-term system stability rather than single performance metrics.
By controlling hydration behavior, rheology, and structure development,
we help customers achieve consistent results across different environments.
Because in the end —
performance differences come from formulation design.
