Why epoxy flooring has grown so fast in India
A decade ago, most Indian factory floors were plain trowelled concrete or IPS with a hardener. Today, epoxy and PU floors are routinely specified in new plants. A few practical reasons drive this change:
- Dust control: Bare concrete keeps releasing fine dust under traffic. Pharma, electronics, food and auto component units cannot accept that dust on products.
- Audits and certifications: GMP, FSSAI, ISO and export customer audits look closely at floors that can be cleaned and kept hygienic.
- Warehousing growth: Large logistics parks need durable floors for pallet trucks and clear line marking.
- Safety: Anti-skid textures and marked walkways reduce slip accidents.
- Appearance: Clean, bright floors improve lighting and leave a good impression on visiting customers.
Indian climate and site conditions that affect epoxy floors
Much of the published guidance on resin floors is written for cooler, drier countries. India is different, and the specification has to reflect that.
| Condition | What happens | What to specify |
|---|---|---|
| Monsoon humidity | Moisture condenses on cool slabs; amine blush and poor bonding | Check dew point; work in daytime; use blush-resistant products |
| Ground water and no damp-proof membrane | Moisture rises through ground-bearing slabs and lifts the coating | Moisture test before work; moisture-tolerant primer where readings are high |
| High summer temperatures | Short pot life; material sets in the bucket; roller marks | Mix smaller batches; work in the cooler part of the day; store material in shade |
| Cold winter mornings (north and central India) | Slow cure; soft or tacky floors | Allow longer cure; avoid application below the TDS minimum |
| Strong sunlight near doors and in open sheds | Epoxy yellows and chalks | UV-stable PU top coat in sunlit zones |
| Coastal salt air | Corrosion of embedded steel and salts on surfaces | Thorough cleaning; check for salt contamination before coating |
The Indian slab problem: new construction and old floors
In new projects, the floor is often coated as soon as the civil contractor hands over, sometimes within one or two weeks of casting. Concrete still contains a lot of water at this stage. Coating it seals that water in, and it will try to escape later, often as blisters. Where the programme is tight, ask for a moisture-tolerant primer and test before work rather than hoping for the best.
Older Indian floors bring other issues: oil-soaked concrete in machine shops, IPS floors with weak top layers, Kota or tile floors in older buildings, and repeated layers of cheap floor paint. Each needs a different preparation method. Grinding is suitable for most sound floors; shot blasting is efficient for large open areas; heavily contaminated or weak surfaces may need scabbling or repair mortar first.
Which epoxy system suits which Indian industry
| Industry | Main demands | Common system |
|---|---|---|
| Pharma and API units | GMP hygiene, cleanability, no dust, chemicals | Self-levelling epoxy with coving; anti-static where solvents are handled |
| Food, dairy and beverage | Wet cleaning, hot water, acids from milk and fruit | Anti-skid epoxy or PU concrete in hot or wet zones; see food grade epoxy in India |
| Auto and engineering | Oil, coolant, trolleys, dropped parts | Heavy-duty coating or mortar; anti-skid near machines |
| Electronics and data centres | Static control, dust-free | Anti-static (ESD) epoxy with grounding |
| Warehouses and logistics | Pallet trucks, forklifts, line marking | Self-levelling or high-build epoxy with marking |
| Hospitals and labs | Infection control, chemical disinfectants | Self-levelling epoxy with coving |
| Commercial car parks | Tyre traffic, ramps, sunlight at entries | Anti-skid epoxy with PU top coat at exposed areas |
| Chemical and battery rooms | Acids, solvents, spills | Chemical-resistant (novolac type) epoxy |
How to write a proper epoxy floor specification
Many Indian tenders simply say "epoxy flooring, 2 mm". That is not enough to compare quotes or hold anyone accountable. A useful specification includes:
- Substrate requirements: minimum concrete age, maximum moisture reading, required surface strength.
- Preparation method: grinding or shot blasting, crack repair method, treatment of joints.
- System build-up: primer, body coat, top coat, with product names and coverage for each.
- Total thickness: stated in microns or mm, with how it will be checked on site.
- Finish: gloss, semi-gloss, anti-skid grade, colour reference.
- Details: coving height, edge terminations, drain detailing, line marking.
- Curing and handover: days before foot traffic, vehicles and chemicals.
- Documents: technical data sheets, material test certificates, batch numbers and a written application record.
Cost of epoxy flooring in India: what really drives it
Price per square foot varies widely across India because quotes cover very different scopes. Before comparing numbers, make sure every quote describes the same thing. The biggest drivers are:
- System and thickness: a roller coating and a 3 mm self-levelling floor are not comparable products.
- Preparation scope: removing old paint or oil can cost as much as the coating itself.
- Raw material content: solids content and filler level differ between products; a low price per litre can mean less resin per square foot.
- Location and logistics: remote sites, small areas and night work add cost.
- Specialities: ESD, chemical resistance, coving and marking.
A practical way to compare quotes is to ask each supplier for the kilograms of material per square metre for each layer. This exposes thin systems quickly.
Buying from a manufacturer vs a trader
In India, epoxy flooring is sold through manufacturers, distributors, traders and applicators, and the same product can pass through several hands. Buying directly from a manufacturer usually gives three advantages:
- Matched system: primer, body coat and top coat are designed to work together.
- Technical support: the people who formulate the product can advise on unusual sites and failures.
- Traceability: batch numbers and test certificates come from the source.
Whoever you buy from, ask for the technical data sheet, the safety data sheet, a sample or trial patch, and references from similar sites.
Pre-work checklist for Indian sites
- Concrete age and moisture recorded.
- Rain forecast checked; roof leaks and wall dampness fixed before flooring.
- Power supply for grinders, shot blasters and vacuum confirmed.
- Area isolated from other trades; no welding or painting above the fresh floor.
- Ventilation planned for solvent-based products; solvent-free systems preferred in occupied buildings.
- Material stored in a shaded, dry place, off the ground.
- Handover dates agreed with production so the floor gets its full cure.
Typical failures seen in India and their causes
| Failure | Likely cause |
|---|---|
| Blisters or bubbles weeks after work | Moisture rising from the slab; coating applied too soon after casting |
| Peeling in sheets | No grinding; laitance, curing compound or oil left on the surface |
| White, greasy film on surface | Amine blush from humidity or low temperature during curing |
| Yellowing near doors and windows | UV exposure on an epoxy top coat |
| Cracks following a straight line | Expansion or construction joint bridged with rigid epoxy |
| Fast wear paths | Coating too thin for the traffic; no grit control |
A worked example: specifying a floor for a mid-size Indian plant
Consider a typical new engineering plant in an Indian industrial estate: a 2,000 m² shed with an assembly line, a machining bay, a store and a small canteen. Rather than one system for the whole building, a sensible plan would split it by use:
- Assembly line: high-build epoxy coating or 1.5–2 mm self-levelling, with yellow walkway marking.
- Machining bay: epoxy mortar or a thick quartz-filled system with anti-skid texture, because coolant, chips and dropped parts are common.
- Store: a wear-resistant epoxy coating suited to pallet trucks.
- Canteen and wash area: anti-skid epoxy with coving and slope to drains.
- Doorways and loading bay: PU top coat where sunlight falls on the floor.
Zoning like this usually costs less than over-specifying the whole floor, and performs better than under-specifying it.
Safety during application
- Use gloves and eye protection; uncured epoxy can cause skin sensitisation.
- Ventilate enclosed areas, especially with solvent-based primers.
- Keep flames, welding and smoking away from solvent-based products.
- Barricade the area and post signs so nobody walks on uncured floors.
- Dispose of empty tins and waste as per local rules.

Kaam se pehle slab ki moisture check karo, grinding karwao, aur poora system ek hi manufacturer se lo. Quote compare karte waqt har layer ki thickness aur material likhwa ke lo.
Epoxy flooring in India: FAQs
Can epoxy flooring be done during the monsoon in India?
It can be done indoors if the slab moisture, humidity and dew point are within the product limits. Many failures happen when coating is done on damp slabs or during high-humidity evenings, so testing and timing are essential.
How long after casting concrete can epoxy flooring be applied?
The usual guideline is about 28 days so that most moisture can leave the slab. If the schedule does not allow this, a moisture-tolerant primer is used after testing.
Is epoxy flooring suitable for Indian homes?
It is used in garages, terraces under cover, utility areas and some designer interiors. For living areas, check slip resistance, sunlight exposure and the condition of the existing floor before choosing it.
Which is better in India, epoxy or PU flooring?
Epoxy is preferred for most dry and moderately wet indoor areas. PU concrete is preferred where hot water, thermal shock or heavy wet processing is involved. Many plants use both in different zones.
How do I compare two epoxy flooring quotes?
Ask both suppliers for the system build-up, products, material quantity per square metre for each layer, total thickness and preparation method. Compare these, not just the price per square foot.
Do you supply epoxy flooring outside Maharashtra?
Yes. Swaraj Polycoats manufactures in Nashik and supplies epoxy flooring systems and application support across India.
India mein epoxy flooring kab fail hoti hai?
Zyada tar geela slab, bina grinding ke kaam, ya jaldi traffic chalu karne se. Moisture test aur sahi preparation se yeh problem bachti hai.
