IPCS wall putty formula covers white cement putty, acrylic putty and polymer-modified putty — all with complete batch SOP, raw material specifications and QC parameters. See wall putty machine page for machine recommendation.
White Cement Putty
40–55% white cement + 30–45% CaCO3 + 5–10% additives (RDP, HPMC, anti-crack). Most common grade. Works in ribbon blender.
Acrylic Putty
Polymer binder base. More flexible, better crack resistance. Higher cost but premium market positioning.
Polymer-Modified
White cement + RDP (Redispersible Polymer Powder). Balance of cement strength and polymer flexibility.
| Ingredient | Function | % Range |
|---|---|---|
| White Cement | Binder, strength | 40–55% |
| Calcium Carbonate (GCC) | Filler, smooth finish | 30–45% |
| RDP (Redispersible Polymer Powder) | Flexibility, adhesion | 2–5% |
| HPMC / Cellulose Ether | Workability, open time | 0.2–0.5% |
| Anti-crack agent | Crack resistance | 0.5–1% |
White Cement Putty & Waterproof Wall Putty
White Cement Putty
The standard interior putty grade — 40-55% white cement, 30-45% calcium carbonate filler, polymer and HPMC additives. Most widely manufactured putty product globally.
Waterproof Wall Putty
Enhanced polymer loading (4-6% RDP vs 2-3% standard) and added hydrophobic additive for exterior and damp-prone interior wall applications where moisture resistance is critical.
Cement Based Wall Putty
The broader category encompassing both standard and waterproof grades — distinguished from gypsum-based putty by superior moisture and alkali resistance on masonry substrates.
Frequently Asked Questions
What is the formula for white cement wall putty?
White cement (40–55%), calcium carbonate filler (30–45%), RDP redispersible polymer powder (2–5%), HPMC cellulose ether (0.2–0.5%), anti-crack agent (0.5–1%). IPCS provides exact percentages calibrated for your raw material grades.
What machine is needed to make wall putty?
Ribbon Blender (horizontal double helix) for standard dry powder putty — batch size 100–2000 kg. Twin Shaft Mixer for polymer-modified putty with higher RDP content. IPCS recommends based on your formula and output.
What is RDP and why is it used in wall putty?
RDP (Redispersible Polymer Powder) is a VAE or acrylic co-polymer in dry powder form. When mixed with water, it re-emulsifies to provide polymer film formation — improving adhesion, flexibility and crack resistance of the putty.
What is HPMC and why is it used in wall putty?
HPMC (Hydroxypropyl Methylcellulose) is a cellulose ether that provides water retention, workability and open time for the wet putty application. Without HPMC, the putty dries too fast and shows application lines.
What is the pot life of wall putty after mixing with water?
Standard white cement putty has a pot life of 30–60 minutes after mixing with water, depending on HPMC grade and ambient temperature. IPCS formula specifies the correct HPMC grade for your target pot life.
What coverage does wall putty provide?
Standard white cement putty covers 10–16 sq ft per kg (single coat, 1mm thickness). IPCS formula targets 12–14 sq ft/kg as a QC parameter.
What is the difference between acrylic putty and white cement putty?
White cement putty is economical, alkaline (good compatibility with emulsion paint) and requires curing before painting. Acrylic putty (polymer binder base) is more flexible, crack-resistant and can be painted over sooner, but costs more.
Where to source white cement for wall putty in India?
White cement from ACC (Ultratech White Cement), Birla White distributors nationwide. 52.5 grade recommended. IPCS provides grade specification and vendor contacts as part of formula support.
Can I produce wall putty and emulsion in the same factory?
Yes — the same HSD, SS tanks and filling machine serve both products. A Ribbon Blender is additionally required for the putty. IPCS designs factory layout to accommodate both product lines efficiently.
What is the market demand for wall putty?
Wall putty demand in India is growing at 8–12% annually driven by residential construction in Tier 2 and Tier 3 cities. It is one of the most stable-demand, high-margin products in the paint-adjacent category.
