Wall Putty Formulation Guide (Complete Technical & Commercial Optimization Guide)
What is Wall Putty?
Wall putty is a cement-based surface finishing material applied before painting to create a smooth, durable, and uniform substrate. A high-performance wall putty formulation improves paint adhesion, reduces cracks, and enhances surface durability.
Standard Wall Putty Formulation (Reference Formula)
Typical White Cement Wall Putty Formula:
| Raw Material | Ratio (%) | Function |
|---|---|---|
| White Cement | 30–40 | Binder |
| Calcium Carbonate | 55–65 | Filler |
| HPMC | 0.3–0.5 | Water retention & workability |
| RDP Powder | 1–2 | Adhesion & flexibility |
| Additives | 0.2–0.5 | Performance enhancement |
Key Raw Materials & Functional Mechanisms
HPMC (Hydroxypropyl Methyl Cellulose)
- Controls water retention
- Improves workability and open time
- Prevents cracking due to rapid drying
