Consider the scenario where a couple moving into a resale 2BHK are given three painting quotes over a weekend. The first says ₹28,000, the second ₹46,000 and the third ₹61,000. The weirdly humorous part is that the painter behind those looks mildly offended when asked why. They are not lying or trying to mislead in any way.
A painting quote is a stack of small decisions with only the total handed to you. This is why the cost of painting a 2BHK flat can feel like a “coin toss” when you’re simply comparing paper. There’s more to it: arithmetic with hidden inputs that you need to know to justify the quote.
To bring them to you, we’ve leaned on the one source that prices them in the open. The Central Public Works Department publishes the Delhi Schedule of Rates. It’s a line-by-line price book that government engineers use to estimate everything from putty to the final coat.
It’s public, and it’s itemised. Nobody is trying to sell you a package.
Later in the article, we also use the Delhi numbers to realistically estimate for Mumbai, Bengaluru, Pune, Chennai, Hyderabad and Kolkata.
Start with the area
Most of the confusion begins before any paint is opened. The carpet area in your sale agreement is one number. The paintable area includes every wall and ceiling surface a roller will touch. That is an entirely different number.
Let’s say one of your bedrooms is 12 ft by 10 ft, with a 9 ft ceiling. The four walls come to 396 sq ft. Of course, a door of about 21 sq ft and a window of about 16 sq ft come off the total, leaving 359 sq ft. The ceiling adds 120.
That’s roughly 480 sq ft of paint surface over 120 sq ft of floor. This is four times the carpet area figure.
But tiled bathrooms and kitchen splashbacks don’t take emulsion. The rule of thumb contractors use for a full flat usually lands between 2.5 and 3.5 times carpet area. So, if you take an 850 sq ft flat: at 2.5 you’re painting about 2,125 sq ft. At 3.5 it’s nearly 2,975, a 40 per cent difference.
Also, the Bureau of Indian Standards method of measurement for painting of building surfaces, IS 1200 (Part 13), works in square metres. It makes no deduction for openings up to 0.5 sq m each, which is about 5.4 sq ft. This means small windows and ventilators stay in the measured area. Openings between 0.5 and 3 sq m are deducted.
The standard also says the number of coats must be stated for every item. Ask your painter which convention the quote follows.
What a government price book puts on a square metre of wall
The CPWD’s Delhi Schedule of Rates 2023 lists painting under its finishing chapter (sub-head 13.0). Each item bundles material, labour, and the contractor’s margin. Rates are per square metre, and one square metre is 10.76 sq ft.
For interior walls on new plaster, three items do most of the work:
- White cement-based wall putty: About 1 mm thick. ₹156.05 per sq m, or roughly ₹14.50 per sq ft.
- Water-thinnable cement primer: ₹73.95 per sq m or about ₹6.87 per sq ft.
- Acrylic emulsion, two coats: ₹137.45 per sq m or about ₹12.77 per sq ft. The premium interior grade is listed at ₹142.80.
If you stack putty, primer and two coats of standard emulsion, you get ₹367.45 per sq m, close to ₹34.14 per sq ft. For the premium grade, it’s ₹372.80, about ₹34.63.
These are reference rates for government work. Market painters repainting walls often skip putty, buy paint at dealer rates and run thinner margins.
Treat the schedule as a benchmark for a full new-work specification, but not a price you’re owed.
2BHK painting cost, worked from the schedule
Take the 850 sq ft flat again and price it two ways, using the DSR 2023 rates.
First, for a repaint on sound walls with no putty. This would just have primer and two coats of standard emulsion, putting the schedule at ₹211.40 per sq m.
Second, the full build-up with putty at ₹367.45.
At 2.5 times carpet area, about 197 sq m of surface:
- You get roughly ₹41,700 without putty
- You get roughly ₹72,500 with putty
At 3.5 times, the number is about 276 sq m. You get:
- You get roughly ₹58,400 without putty
- You get roughly ₹1,01,600 with putty
With GST, you add 18 per cent on top of the quote. The 2.5 times cells in a table then read about ₹49,200 and ₹85,600.
3BHK painting cost (why it isn’t 2BHK plus one)
At the same multiplier, the 3BHK painting cost in the schedule scales almost one for one with area. This is because a price book bills by the square metre and has no bulk discount built in.
A 3BHK with 1,200 sq ft of carpet area, at 2.5 times, comes to about 279 sq m. That’s roughly ₹58,900 without putty and ₹1,02,400 with it. This is about 1.4 times the 2BHK.
Contractors often quote a lower rate per foot on larger jobs. The reason is that masking, set-up and crew movement get spread across more wall. That’s not something the schedule records; ask for it instead of assuming it.
There’s also a trade-off worth admitting here.
Bigger flats usually mean:
- More bathrooms
- A storeroom
- A utility balcony
Each of those has its own damp and stain issues. A 3BHK quote that looks cheap per foot may have forgotten to consider those rooms. This possibility makes it prudent to read the room list, along with the total.
Fresh work versus repainting
The schedule prices new work and old work separately. The gap is large.
Smooth exterior acrylic on new work, applied over a primer, is ₹160.60 per sq m. The same paint on old work, two or more coats, is ₹120.75. This is about 25 per cent lower. For one coat on old work, the price drops to ₹80.65.
Waterproofing cement paint follows the same pattern: ₹116.90 for new work and ₹75.80 for old. There is a 35 per cent difference here.
All of these are listed in the finishing chapter of DSR 2023.
The logic here isn’t really mysterious. Good and previously painted walls don’t need the full preparation that raw plaster does, so fewer items go into the rate calculation. That’s the honest reason a repaint costs less. It’s also the test for a repaint quote that looks too good to be true.
If the walls are chalky, patchy or damp, the cheaper old-work rate stops being meaningful. Ask the contractor to look at the walls in daylight before agreeing to it.
Preparing a Quote for Delhi
The CPWD schedule is responsible for pricing in Delhi. That makes Delhi NCR the one market in this article with an official, line-by-line number behind it. Outside Delhi, government estimators work from state and city schedules: the Karnataka PWD common schedule of rates for Bengaluru, the Tamil Nadu PWD and Highways schedule for Chennai, the Telangana common schedule for Hyderabad, the Maharashtra PWD and Mumbai municipal schedules for Mumbai and Pune, and the West Bengal PWD and Kolkata Municipal Corporation schedules for Kolkata. Most state schedules also allow the CPWD Delhi schedule as a fallback for items they don’t list.
We’ve used a rate-analysis tool, InfraLens, which works out the cost of putty, primer and two coats of interior emulsion per square metre in each city from current market prices. We use only the percentage gap between each city and Delhi, not InfraLens’s rupee figures, which rest on a different putty specification than the CPWD schedule.
The gaps are applied to the Delhi figures above.
850 sq ft flat (2BHK)
| City | Cost compared with Delhi | Repaint, no putty | Full build-up with putty |
|---|---|---|---|
| Delhi (CPWD DSR 2023) | – | ₹41,700 | ₹72,500 |
| Mumbai | about 3% higher | ₹43,100 | ₹74,900 |
| Bengaluru | about 1% higher | ₹42,200 | ₹73,400 |
| Pune | about the same | ₹41,700 | ₹72,500 |
| Chennai | about 3% lower | ₹40,600 | ₹70,600 |
| Hyderabad | about 5% lower | ₹39,800 | ₹69,100 |
| Kolkata | about 5% lower | ₹39,600 | ₹68,900 |
Indicative cost (estimate) for an 850 sq ft flat (2BHK), 2.5 times carpet area, before GST. The rupee amounts in those columns are not InfraLens figures. Each one is calculated from the CPWD Delhi rates, multiplied by the paintable area, and then adjusted by the city’s percentage gap. For example, Mumbai’s ₹43,100 is Delhi’s ₹41,734 × 1.032.
A breakdown of the Delhi cost calculation
Step 1: Area to paint
850 sq ft × 2.5 = 2,125 sq ft. The CPWD rates are per square metre, and 1 sq m is 10.764 sq ft, so 2,125 ÷ 10.764 = 197.4 sq m.
Step 2: Delhi rate per sq m
- Without putty: primer ₹73.95 + two coats of emulsion ₹137.45 = ₹211.40
- With putty: those two plus putty ₹156.05 = ₹367.45
- (CPWD 2023, page 223)
Step 3: Multiply
- 197.4 × ₹211.40 = ₹41,734, which rounds to ₹41,700
- 197.4 × ₹367.45 = ₹72,545, which rounds to ₹72,500
The two figures are for the same job, with and without putty. The difference between them (about ₹30,800) is the cost of putty over 197.4 sq m.
1,200 sq ft flat (3BHK)
| City | Repaint, no putty | Full build-up with putty |
|---|---|---|
| Delhi (CPWD DSR 2023) | ₹58,900 | ₹1,02,400 |
| Mumbai | ₹60,800 | ₹1,05,700 |
| Bengaluru | ₹59,600 | ₹1,03,600 |
| Pune | ₹58,900 | ₹1,02,400 |
| Chennai | ₹57,400 | ₹99,700 |
| Hyderabad | ₹56,100 | ₹97,600 |
| Kolkata | ₹56,000 | ₹97,300 |
Indicative cost, 1,200 sq ft flat (3BHK), 2.5 times carpet area, before GST. The process behind the calculation has already been mentioned below the previous table.
Treat these as a sanity check, not a quote. The city gaps come from a modelled estimate that, by its own description of the method, is not a substitute for an official schedule of rates.
Reading a quote line by line
Going back to the beginning, which of those three weekend quotes was wrong? The answer is: probably none. That is, until you line them up on the same terms.
Put them side by side and check these items:
- Area basis, and the measured figure it was applied to
- Putty – how many coats, and whether crack repairs are priced separately
- Primer – by product name
- Emulsion brand, product line and number of coats
- Ceilings, wood, metal grilles and bathrooms – in or out
- Furniture shifting, masking and debris removal
- GST, payment schedule and handover date
On GST, painting where the contractor supplies both paint and labour is treated as a work contract under heading 9954 (construction services) of the GST rate notification. This is normally billed at 18 per cent, made up of 9 per cent central tax and an equal state share. The same source notes that a labour-only job for a residential homeowner can be exempt. So ask how your quote is structured.
For instance, on a ₹45,000 job, 18 per cent is ₹8,100 you’d rather not meet at the end; ask whether the figure is before or after tax.
Once the quotes match on those lines, compare the totals. The cheapest is often scrapped because it assumes a single coat of putty and no primer. The most expensive might include repairs the other quotes never mention.
What quietly inflates the bill
Surface condition can be why your bill goes up. Damp patches near bathrooms and on external walls need their source treated before paint goes on. This means hairline cracks need filling and powdering old distemper has to be scraped back.
Each adds a day or two of labour and some material. None of it appears in a per-foot rate quoted over the phone.
The schedule shows what separate damp-proofing costs. Waterproofing cement paint on new work is listed at ₹116.90 per sq m, about ₹10.86 per sq ft. That’s on top of whatever finish coat follows. The shade you choose adds cost as well; going from deep green to off-white often needs an extra coat and sometimes a tinted primer.
At Colour Valley Paints, we make interior wall paints along with wall putty and primers. The arithmetic is plain. The money saved by dropping a primer coat is little next to the cost of repainting a wall that peels.
Choosing a paint tier without overspending
The schedule’s own numbers are a useful brake on upselling. Inside, the premium interior emulsion is listed about ₹5.35 per sq m above the standard one for two coats in DSR 2023. This is across 197 sq m of wall, which is roughly ₹1,050. Outside, the gap widens.
Smooth exterior acrylic for new work is ₹160.60 per sq m, the silicone-enhanced premium grade ₹171.10, and the top premium exterior grade ₹181.25 (about 13 per cent above the base one).
Where a better emulsion pays off
It’s great for living rooms, children’s rooms and the stretch of wall just inside the front door. Those surfaces are exposed to hands, bags and school shoes. A washable finish there can mean wiping a mark off instead of repainting a wall.
Where it doesn’t
It’s not suitable for ceilings in rooms you rarely look up in. Or the guest room or the storeroom. Plain white ceiling emulsion is cheap for a reason. You’re unlikely to miss the difference in a spare bedroom.
What to do before you sign
The cost of painting a 2BHK flat in 2026 sits inside a wide band. It’s wide for reasons you can mostly see once you look. This includes area basis, whether putty is included, how much preparation the walls need, which paint goes on top and the city you live in.
A 3BHK stretches the same logic across more rooms and a bigger bill.
You must measure the paintable area yourself. Get every quote itemised, with brand and coats on paper. Ask about GST.
The risk was always paying for a finish that peels, stains or fades inside a year. Worse, you then find out that the cheaper quote you chose had left out the step that would have prevented it.
A wall repainted twice costs more than a wall painted properly once. Colour Valley Paints is open to a discussion if you’d like to see what the product side of that conversation looks like.
