Gypsum plastering has increasingly become the preferred choice over sand cement plastering for interior walls across India. One of the key questions builders and homeowners ask is: what does gypsum plastering actually cost? This guide covers the full picture — material costs, application rates, and how gypsum compares to cement plastering overall.
Gypsum Plaster Cost Per Sq Ft (2024–25)
The applied cost of gypsum plastering typically ranges between ₹32 and ₹55 per sq ft, depending on location, substrate, thickness, and contractor.
| Cost Component | Gypsum Plaster | Sand Cement + PoP |
|---|---|---|
| Material (per sq ft) | ₹18–₹28 | ₹22–₹35 |
| Labour (per sq ft) | ₹12–₹20 | ₹18–₹28 |
| Putty (per sq ft) | Not required | ₹8–₹15 |
| Curing water cost | Nil | ₹2–₹4 |
| Total (approx) | ₹32–₹55 | ₹50–₹85 |
Why Gypsum Is More Cost-Effective
The cost advantage of gypsum plastering comes from multiple directions:
- No putty required: Gypsum produces a smooth enough finish for direct painting. Sand cement walls require an additional putty layer before paint, adding ₹8–15/sq ft.
- No water curing: Cement plaster requires 7 days of water curing after application. This adds labour cost and significantly increases water consumption.
- Faster completion: Gypsum is paint-ready in 3–4 days vs 15–21 days for cement. Faster completion means lower project overheads and earlier handover.
- Less labour intensity: Gypsum comes pre-mixed in bags — no sand measuring, mixing, or waste. This reduces on-site labour requirements.
- Reduced electricity: The faster setting and no-curing process reduces electricity consumption on site.
Our internal research shows gypsum plastering saves approximately ₹35 per sq ft in overall project cost compared to the sand cement + PoP combination when all factors are included.
Gypsum Plaster Bag Price
A 25 kg bag of gypsum plaster typically costs between ₹500 and ₹750 depending on brand and location. One bag covers approximately 50–60 sq ft at standard wall thickness (11mm). Material cost per sq ft therefore works out to approximately ₹9–₹15 for the plaster material alone — significantly cheaper than the combined cement + sand + putty equivalent.
Factors That Affect Gypsum Plastering Cost
- Substrate type — AAC blocks, hollow blocks, and brick behave differently. AAC blocks may require a bonding agent for first application, adding slight cost.
- Wall condition — New construction is straightforward. Renovation over existing plaster may require surface preparation, adding cost.
- Thickness required — Standard wall thickness is 11mm; ceilings 8mm. Uneven walls requiring thicker application will increase material cost.
- City and location — Labour rates vary significantly across cities. Rates in Chennai, Bangalore, and Coimbatore differ from tier-2 towns.
- Project scale — Large builder projects (50,000+ sq ft) typically get better rates than individual home projects.
