Plastering Cost Per Sq Ft in India (2026)

₹14 to ₹22 per square foot. That is what a 12 mm internal cement plaster costs, all in, across most of India in 2026 — and it is the number that quietly governs the ₹30-per-square-foot paint and the ₹120-per-square-foot stone that go on top of it. Plaster is the base coat of the whole building: nobody admires it, everybody stands on its result. A wall plastered true and cured properly takes putty, paint and cladding cleanly; a wall plastered in a hurry telegraphs every hollow and undulation through whatever is laid over it, and no amount of expensive finish hides it.

Plastering is also the line item where owners are most easily confused, because the same wall can be quoted at ₹14 or ₹45 depending on whether the number is per square foot of plaster, per square foot of wall including both faces, which plaster, which thickness, and whether scaffolding, curing and surface prep are inside the rate. This guide puts honest 2026 ranges on the table, breaks one square foot of internal plaster into its cement, sand, labour and sundry parts so the number can be checked, and sets out what moves the price and how to save without buying a bad base. Rates are indicative October 2026 and vary by city, thickness and quantity — confirm locally before budgeting.

The headline ranges

There are three plasters an Indian home uses, and their prices are close enough that the choice is about the wall, not the budget. Cement (sand) plaster is the workhorse for internal and external masonry; gypsum plaster is a factory-bagged interior finish that is poured and levelled in one go, skipping the putty stage; and both price per square foot of plastered face. The table gives indicative 2026 ranges, with the drivers that push a job to the top or bottom of each band.

Two things explain the spread. First, external plaster costs more than internal of the same thickness because it is applied in two coats over a thicker build, usually carries a waterproofing admix, and needs scaffolding — the wall is simply harder and slower to reach and finish. Second, gypsum sits above cement plaster per square foot but can work out competitive on an interior wall, because it is laid in one levelled coat and removes the two-coat putty stage that a cement-plastered wall then needs before paint. It is an interior-only material, though: gypsum has no place on an external wall or a permanently wet one.

Read the bands as overlapping, not fixed lines. A simple internal wall in a tier-2 town with a continuous job can sit near the bottom of the ₹14-22 range; the same wall in a metro, above the third floor, with patch-work and surface prep, drifts to the top or past it. The gap between internal cement and gypsum is real but narrows once the putty stage is counted: a cement wall needs two coats of putty, a primer and paint before it looks finished, while a gypsum wall is taken straight to primer. On an interior wall where appearance matters, compare the finished-to-paint cost of each route rather than the plaster rate alone — that is the honest comparison, and it often brings the two much closer than the headline numbers suggest.

Where the ₹14-22 goes: one square foot, itemised

The best way to sanity-check a plastering quote is to build the number up from its parts. The table below breaks one square foot of 12 mm internal cement plaster, mixed about 1:5, into cement, sand, labour and sundries. The lines add to the ₹14-22 band, and the striking fact is how small the material is: cement and sand together are only ₹4-7, while the mason-and-helper labour is ₹8-12. Plaster is a labour product, which is why the rate tracks local wages far more than the price of a cement bag.

It is worth translating the per-square-foot rate into a whole-wall number, because that is where the money is felt. A single room of 10 × 12 ft with a 10 ft ceiling has roughly 440 sq ft of wall to plaster on its inside face; at ₹14-22 that is about ₹6,200-9,700 for the internal plaster alone, before putty and paint. Scale that across a 3BHK and plaster becomes a real line — ₹60,000-1,20,000 or more — yet it is still a fraction of the finishes it carries, which is exactly why cutting it to save a few thousand rupees is a false economy. The sensible instinct is to spend correctly on the base and save on the layers above, not the other way round, because a wall replastered after the paint is on costs several times what it saved.

What changes the price

The same plaster can be quoted ₹10 apart on two jobs in the same city, and the reasons are specific and checkable. Knowing them lets an owner read a quote instead of guessing at it.

• Plaster type and thickness — gypsum sits above cement; external 15-20 mm two-coat costs more than internal 12 mm single coat.
• Labour rate — the biggest line (₹8-15 per sq ft); it tracks local wages and skilled-mason availability more than material prices.
• Height and access — walls and ceilings above about 3600 mm need taller scaffolding and slower working, and the rate rises.
• Surface and substrate — rough, uneven or RCC surfaces need more material and dubbing-out; AAC blocks need the right mix and prep.
• Waterproofing and admixes — external and wet-area plaster carries admixes and sometimes a base coat, adding ₹2-5 per sq ft.
• City and season — metros price above tier-2 towns; sand availability and monsoon logistics move the number locally.
• Quantity and continuity — a whole house plastered in one mobilisation costs less per square foot than small patch jobs.

How to save without buying a bad base

Plaster is the wrong place to cut blindly, because a poor base costs more to hide later than it ever saves. But there is honest money to be found.

• Get the masonry built true — straight, plumb walls need less plaster to correct, which cuts both material and labour.
• Specify the right thickness, not extra — 12 mm internal is standard; paying for 15-18 mm inside is usually wasted mortar.
• Plaster the whole home in one go rather than in patches, to get the lower continuous rate.
• Choose gypsum only where it earns its premium — on interior walls where skipping putty genuinely offsets the higher rate.
• Insist on proper curing — it costs only water and time, and it is what stops cracks that are expensive to chase and repaint.
• Make the quote name the thickness, mix, coats, and whether scaffolding, curing and prep are included — exclusions are where cheap quotes hide.
• Keep gypsum out of wet and external zones — a cheap material in the wrong place fails and is re-done at full cost.

Frequently asked questions

How much does plastering cost per square foot in India in 2026?

Indicatively, about ₹14-22 per sq ft for 12 mm internal cement (sand) plaster, ₹20-32 for external cement plaster, and ₹22-35 for gypsum plaster on interior walls — all-in, including labour and material. Ceiling plaster runs about ₹18-28. Rates vary by city, thickness, height and quantity, and surface preparation adds ₹2-5; confirm locally before budgeting (indicative October 2026).

Is gypsum plaster cheaper than cement plaster?

Per square foot, gypsum is usually a little dearer (₹22-35 against ₹14-22 for internal cement). But gypsum is laid in one levelled coat and removes the separate putty stage a cement wall needs before paint, so on an interior wall the finished cost can be competitive. Gypsum is interior-only, though — never use it on external or permanently wet walls, where cement plaster is required.

Why is labour more than material in a plastering quote?

Because plaster is a labour product. For one square foot of 12 mm internal plaster, the cement and sand together are only about ₹4-7, while the skilled mason and helper time is ₹8-12. That is why plastering rates track local wages and mason availability far more than the price of a cement bag, and why the same material costs more in a metro than a smaller town.

Does the plastering rate include scaffolding and curing?

It should, but not every quote says so — which is where cheap-looking numbers come from. Always have the quote state the thickness, the mix, the number of coats, and whether scaffolding, curing and surface preparation are included. A rate that excludes scaffolding or curing is not cheaper, only incomplete, and skipped curing shows up later as cracks you pay again to repair and repaint.
