More cellulose ether does NOT always mean better mortar performance.
Common formulation mistakes:
❌ Excessive dosage
❌ Overly high viscosity
❌ Poor dispersion
❌ Ignoring substrate and temperature conditions
may cause:
Sticky mortar
Poor workability
Cracking
Reduced bonding strength
Lower compressive strength
The right balance of dosage, viscosity, formulation design, and construction conditions is the key to stable dry-mix mortar performance.
✔ Better water retention
✔ Improved anti-sagging
✔ Smoother application
✔ More reliable strength development
