Is India's industrial capex boom creating a hidden opportunity in paints and coatings?

Quick summary: India's paint industry is almost always analysed through decorative demand, so the structural shift happening underneath it goes under-read. A multi-lakh-crore capex supercycle across infrastructure, oil and gas, power, nuclear, renewables, defence, railways and shipbuilding is feeding a much smaller but faster growing, higher margin pool of industrial, protective and marine coatings. The opportunity is real but narrow: it accrues to a handful of companies with certified, specification-locked product lines, led by JSW Dulux (International brand) and Berger Paints (Chugoku marine joint venture), while the two largest decorative names are largely bystanders. The actual prize is protective coatings, and the companies still trade on decorative.

Walk into any discussion of Indian paints and the frame is predictable. It is about home renovation, rural penetration, per-capita consumption of roughly 3.5 to 4.5 kg a year against a global 12 to 13 kg, and the price war that Birla Opus ignited in decorative paint. All of it is true. None of it is the whole story.

Sit in the same conversation and ask instead about the paint that goes on a refinery, a nuclear reactor, a railway coach, a wind-turbine blade, a bridge or the hull of a warship, and the answer changes shape. That paint is specified into the design years before tendering, approved by certification bodies and class societies, and rarely switched once it has been proven. It is steadier, higher margin and growing faster than decorative. And a national capex boom is feeding it from almost every direction at once.

This article is about that second conversation. It is an investigation into whether India's industrial capex boom is creating a hidden opportunity in paints and coatings, and why the way the market prices paint companies may not yet reflect it.

Why the decorative lens hides the industrial story

The paint market in India is roughly a ₹75,000 crore-a-year business, and decorative paint accounts for more than 70 percent of it. Because that is where the volume, the brands and the consumer mind share live, the sector is analysed through it. Every analyst note, every earnings call question, every price tracker focuses on the decorative price war.

Industrial and protective coatings, the roughly ₹22,000 to 25,000 crore pool underneath, behave completely differently. Demand is project-led, tied to capital expenditure rather than consumer sentiment. Orders are won through engineering specifications, not shelf presence. Pricing is more stable because it is protected by certification barriers. And right now it is growing high single digit, with protective coatings specifically growing at 8 to 10 percent a year.

The industrial pivot is not secret. Management teams and rating agencies talk about it openly. What is under-appreciated is the mechanics: which companies can actually win the work, how defensible their positions are, and the fact that these names are still valued as if decorative demand were the only thing that mattered.

Every capex stream spends on coatings

The unifying observation is that India is in a multi-year capex supercycle across almost every asset class that consumes protective coatings, and the streams compound rather than run in parallel. The same coating system that protects a refinery also protects a nuclear plant, a bridge, a railway coach and a coastal structure.

The detail that matters for coatings is the maintenance cycle. A ship dry-docks roughly every four years, and roughly a quarter of a fleet re-coats every year. This is the recurring, annuity-like half of the marine thesis, and it is the part least discussed.

The moat is the specification, not the brand

In decorative paint, the customer walks into a store and picks a shade. In industrial coatings, the customer rarely chooses anything. The coating is written into the project design at the engineering stage, before commercial tendering begins. The product must carry approvals from class societies, bodies like NSF, WRAS, API and BIS, and certification is a cumulative stack that a new entrant must replicate from zero.

Switching is hard for a reason. A coating system must be validated in the field, sometimes over years. One bridge system in the research was validated through a three-year sea study before it was accepted. Displacement is possible, but only through field-proven performance, never on price alone. The net effect is that a small group of domestic incumbents with the certification stack and the specification presence is structurally protected.

This is the part of the thesis that makes the cycle defensible rather than commodity-driven. Generic paint capacity cannot win this work, which is why the beneficiary set is so narrow.

The value-per-asset upgrade, not just volume

The second mechanism lifting the pool is that coatings are becoming more valuable per asset, not merely more numerous. Regulators and buyers are pushing toward low-VOC, biocide-free, longer-life, fire-resistant and antifouling formulations. Each shift raises the rupee value per litre, per vessel, per asset.

The proof is in the premiumization data. One major company grew decorative volume only low single digit while value grew high single digit, purely on price and mix. Backward integration into resins adds gross margin of 300 to 500 basis points in the affected categories. Longer warranties and higher specification products compound the effect. The pool can grow substantially even at flat physical volume.

JSW Dulux: the focused franchise, and the accounting noise

The clearest listed exposure sits in JSW Dulux, the entity created when JSW Paints acquired Akzo Nobel India for ₹8,926 crore, closing in December 2025 and renamed with the Dulux brand transferred in. It is the only listed Indian paint company where Marine and Protective is a named core franchise, carrying the International Paint brand.

The operating evidence is consistent. Marine and protective grew double digit through FY25, with the highest-ever monthly revenue recorded in March 2026 on strong order intake across oil and gas, infrastructure, wind-turbine blades and dry-dock work. There is a strategic partnership with the Indian Navy for high-specification anti-corrosive and antifouling coatings on naval vessels, and the business coats a large share of India's nuclear infrastructure. Industrial coatings grew above 25 percent in the first quarter of FY27. Management has stated a target of number one in Marine and Protective by 2031.

The single most important analytical step is separating this operating story from the transaction. The reported metrics make JSW Dulux look startlingly cheap, with a reported P/E of 7.2, EV/EBITDA of 5.7 and return on equity of 80 percent. Those figures are acquisition mechanics, not operating truth. The FY26 profit was inflated by roughly ₹1,846 crore of transaction exceptionals. A paint company with an 80 percent return on equity does not exist in operating terms. Even the cleaner like-to-like computation, around 4 times earnings on a retained basis, is a derived figure and should be read as such.

The more honest caution is cash conversion. Cash from operations is a tiny fraction of EBITDA, far below every listed peer. Whether that reflects real cash-generation weakness or transaction noise is unresolved, and it is the single most important question to answer before trusting the cheap-compounder framing.

The real prize is protective coatings

The largest and steadiest earnings pool over the next five to ten years is protective coatings, not marine. It is the cross-cutting segment that touches infrastructure, oil and gas, power, nuclear and railways all at once, grows at 8 to 10 percent a year, and carries the strongest specification moat.

Here Berger Paints is the incumbent to beat. Its Protecton brand is India's number one protective and infrastructure coating line, supplying refineries, power plants, bridges, airports and nuclear designs. Berger has real marine optionality through its Chugoku Marine Paints joint venture, aligned with the government's naval and maritime focus, though the marine numbers are not separately disclosed. It operates at high-teens margins and is the larger, steadier, already-proven operator.

The honest characterisation of the two leading names is a contrast in risk. JSW Dulux carries the deepest valuation discount and the highest percentage leverage to the industrial and marine mix, but it carries execution, cash-conversion and margin-compression risk that the most recent quarter made concrete. Berger is the higher-quality, higher-margin operator with the number-one protective position, but its valuation already reflects that quality. Neither company's marine slice alone is large enough to be decisive.

Who actually benefits, and who does not

The central correction this analysis makes is to the idea that a paint-sector read of the capex cycle is right. It is not. The marine and protective catalyst accrues to a narrow set.

Kansai Nerolac has the broadest general industrial and powder portfolio, and is the powder-coatings leader, but no marine ship-coating line was found in the research. Asian Paints, the largest name by far at a market cap of roughly ₹252,000 crore, is decorative-led with minimal protective or marine exposure; on this thesis it is effectively a bystander. Shalimar Paints is the most pure marine play, with a century-old line and a relationship with Cochin Shipyard, but it is loss-making with an accumulated-loss balance sheet that constrains its ability to fund a ramp.

The global marine majors, Jotun, Hempel, Chugoku, Nippon, Sherwin-Williams and PPG, hold more than 90 percent of the global marine market and can deploy into India directly or through partnerships. Berger via Chugoku is the most direct listed competitor to JSW Dulux.

The sceptical case

The bull case is well supported. But the sceptical case is not optional, and it is strong on several fronts.

First, the industrial pool sizing itself is built on inconsistent third-party figures. Estimates of the Indian industrial coatings market disagree by roughly three times depending on the source, so every number here is order-of-magnitude, not truth. Second, the protective-specific margin data and coating cost as a share of a large asset were not found in any retrieved source, so the premium-margin argument is partly inference. Third, raw materials are 58 to 60 percent of total cost, the input basket is up 22 to 23 percent versus pre-war levels, and crude derivatives are up 40 to 50 percent. Pricing power in coatings is real but reactive, protecting margins in a band rather than expanding them.

For JSW Dulux specifically, the last reported quarter was a sharp reality check. EBITDA margin fell to 11.93 percent and gross margin fell 533 basis points, with a GST show-cause notice outstanding. Management has guided margin back to 13 to 15 percent, but delivery is unproven, and the decorative price war plus crude and forex headwinds remain live risks.

The most important sceptical point is the size of the prize. Even at generous capture assumptions, the marine slice adds only single-digit percentage points to JSW Dulux's earnings. The thesis stands or falls on margin normalisation and cash conversion, not on ships.

What the market may be missing

The structural insight is not that industrial coatings are a secret. Management, analysts and rating agencies all discuss the pivot openly. What is genuinely under-appreciated is the concentration of the beneficiary set, the procurement and certification moat that protects it, and the fact that these names are still valued on decorative demand while a multi-lakh-crore capex cycle feeds the higher-margin industrial engine underneath.

The companies with meaningful exposure are JSW Dulux, with the only listed core marine and protective franchise, and Berger Paints, with the number-one protective position and real Chugoku marine optionality. Shalimar Paints is the purest marine play but financially constrained, and Kansai and Asian Paints are largely bystanders to the marine thesis.

The biggest uncertainties are not about the capex cycle, which is well funded and reported. They are about earnings conversion. Can JSW Dulux restore its margin and resolve its weak cash conversion? Does the decorative price war persist and drag margins across the sector? Do crude and raw-material costs keep rising? Will the marine catalyst deliver on its planned shipbuilding timeline, or slow and shrink the smallest slice of the thesis?

The specific developments that would determine whether the opportunity translates into sustained earnings are margin normalisation at JSW Dulux, a demonstration that its cash conversion returns to peer-like levels, and evidence that industrial and protective growth continues to outpace decorative across the majors while holding or improving margins. Those, far more than the ship order book, are the signals that would settle whether the market's decorative lens is hiding a real structural cycle or simply a well-flagged but modest pivot.
