The single most searched question about gypsum plastering in South India is: "What is the price per square foot?" The honest answer is that rates vary by city, project size, and site conditions — but the range is predictable, and we will give you the actual numbers.
Quick answer: Gypsum plastering in South India costs ₹35–48 per sq.ft of wall area (supply + apply, all inclusive). For a 1,000 sq.ft home, budget ₹1.2–1.6 lakhs.
Understanding "Square Foot" in Plastering
There is an important distinction. Plastering is quoted on wall area, not carpet or built-up area. For a typical home, wall area is roughly 3 to 3.5 times the carpet area.
- 1,000 sq.ft carpet area ≈ 3,000–3,500 sq.ft wall area
- 2,000 sq.ft carpet area ≈ 6,000–7,000 sq.ft wall area
- 50,000 sq.ft building ≈ 1,50,000–1,75,000 sq.ft wall area
This is why a proper site measurement is essential before quoting — floor area alone does not give an accurate wall area for pricing.

What Is Included in the Rate?
A professional gypsum plastering rate includes:
- Gypsum plaster material (from certified brands)
- Labour for application — screeding, plastering, finishing
- Surface preparation and cleaning
- All tools and equipment
- On-site material storage and logistics
It typically does not include: scaffolding for heights above 12 feet, waterproofing of wet walls, or hacking of existing plaster. These are quoted separately if needed.
What Affects the Final Price?
Project Size
Larger projects cost less per sq.ft. A 50,000 sq.ft apartment complex will get a lower rate than a single 1,200 sq.ft flat. This is because mobilisation, material procurement, and site logistics are shared across more area.
Wall Type
Standard brick masonry and RCC walls are base rate. AAC block walls need additional bonding agent. Old walls with existing plaster to be hacked carry additional charges.
Access and Height
Ground floor or slab-access work is simpler. Areas requiring scaffolding, lifts, or special access carry a premium.
Material Brand
Saint-Gobain Gyproc and USG Boral are premium-tier materials. Cheaper brands are available but may compromise finish quality and durability. Kanish Plasters uses only Gyproc-certified materials.
Cost Comparison: Gypsum Plaster vs Cement + Putty
| Item | Cement Plaster Route | Gypsum Plaster Route |
|---|---|---|
| Plastering (per sq.ft wall) | ₹22–28 | ₹35–45 |
| Water curing (28 days) | ₹8–12 | Nil |
| Putty coat (2 coats) | ₹18–24 | Nil |
| Timeline savings (per floor) | 21 days | 5 days |
| Total cost per sq.ft | ₹48–64 | ₹35–45 |
The saving of ₹15 per sq.ft on wall area on a 1,000 sq.ft home (3,500 sq.ft wall area) = ₹52,500 saved. For a builder with a 10,000 sq.ft building, savings run to ₹5.25 lakhs.

Frequently Asked Questions
Is gypsum plastering priced per sq.ft or per sq.m?
In India, plastering is quoted in sq.ft. For reference, 1 sq.m = 10.76 sq.ft. So ₹40/sq.ft = ₹430/sq.m.
Does the 25kg bag price matter?
Gyproc's 25kg bag covers approximately 1.2 sq.m at 11mm thickness. At ₹350–400 per bag, material cost alone is around ₹30–33 per sq.m or ₹2.8–3 per sq.ft. Labour, overhead, and profit make up the rest of the sq.ft rate.
Can I negotiate gypsum plastering rates?
For larger projects (1,000+ sq.ft wall area), there is usually room to negotiate. For smaller jobs, the mobilisation cost makes it difficult for contractors to reduce rate significantly.
