About Fosroc Nitoflor EPW100

Fosroc Nitoflor EPW100 is a water-dispersed epoxy floor coating and sealer engineered for environments where a hard-wearing, hygienic and dust-free floor matters but where the smell and solvent content of conventional epoxies would be a problem. It is supplied as a three-component pre-packed kit — a base resin, a hardener and a pigmented colour paste — that are blended on site immediately before use, so the contractor gets a consistent, factory-controlled ratio every time without site batching errors. Once mixed and applied, the system cures to a tough, flexible, matt film that bonds tightly to concrete and other cementitious surfaces, locking down surface dust and giving a continuous, easily cleaned seal. Because it is water-based rather than solvent-borne, EPW100 is effectively zero-VOC and odour-free, which is why it is so often specified for occupied buildings, food zones and healthcare areas where solvent fumes are unacceptable. For Indian contractors, consultants and facility managers, EPW100 sits at the value end of the Fosroc Nitoflor flooring range: it is not a high-build self-levelling screed, it is a protective and decorative seal coat that upgrades an existing or new concrete floor at modest cost. Typical Indian trade pricing runs around ₹1,190 per kg, supplied in convenient 4-litre pre-packed kits. The result is a floor that looks clean, sheds dust, resists splashes of common acids, alkalis, oils and detergents, and resists fungal attack — all delivered with a low-odour, environmentally friendlier product that can be brought into service relatively quickly.

The technical insight

The defining feature of EPW100 is that it is a water-dispersed (not solvent-based) epoxy. In a water-based epoxy the resin and hardener are emulsified in water; as the water evaporates and the epoxy-amine reaction proceeds, the particles coalesce into a continuous film. This chemistry is what delivers the zero-VOC, odour-free profile — but it also explains the product’s limits. Water-based epoxies are more sensitive to ambient conditions: Fosroc specifies a minimum application temperature of about 20°C, and curing slows or can be compromised in cold or very humid conditions because the water has to leave the film. The data-sheet build is around 100 microns dry film thickness (about 180 microns wet) applied in two coats, giving roughly 20–22 m² of coverage per 4-litre pack per coat at that thickness. Pot life is short once mixed — on the order of two hours at 20°C and about an hour at 30°C — so contractors should mix only what can be laid in that window. The recoat window is within roughly 24 hours at 20°C (16 hours at 30°C), initial hardness develops in about 24–30 hours, and full chemical cure is reached at around 21 days. Surface preparation is decisive: the concrete must be properly cured, sound, and free of laitance, oil, curing compounds and dust, which is why a Fosroc primer is normally used and why mechanical preparation (grinding or shot-blasting) is recommended for a durable bond. Treat the figures here as the published data-sheet starting point — always confirm against the current Fosroc India TDS for the project’s specification.

Where it is used

• Sealing and dustproofing new or existing concrete floors in light-to-medium duty areas
• Food and beverage facilities — dairies, breweries, bottling halls, commercial and institutional kitchens, food processing plants
• Pharmaceutical, healthcare, hospital and laboratory floors requiring a hygienic, washable, antifungal surface
• Light engineering workshops, assembly areas and packaging halls
• Warehouses, storage and distribution areas needing a clean, dust-free walking and light-traffic surface
• Occupied or sensitive buildings where low odour and zero-VOC application is required
• Decorative colour coating of plant rooms, corridors and back-of-house service areas

Key advantages

• Water-based and effectively zero-VOC — odour-free, so it can be applied in occupied, food and healthcare environments
• Hygienic, impervious matt finish that is easy to wash down and keep clean
• Antifungal — resists mould and fungal growth in damp, humid Indian conditions
• Seals and consolidates dusting concrete, giving a continuous, low-maintenance surface
• Improves floor resistance to many common industrial chemicals, oils, greases and detergents
• Pre-packed three-component kits eliminate site batching errors and give consistent results
• Economical seal-coat solution; available in a range of colours for zoning and aesthetics
• Environmentally friendlier than solvent-borne epoxy coatings

Limitations & considerations

• It is a thin-film seal coat (around 100 microns DFT), not a high-build screed — it will not bridge cracks, level uneven floors or take heavy forklift/impact abuse like a self-levelling or trowel-applied system
• Requires a minimum application temperature of about 20°C and is sensitive to low temperature and high humidity during cure because it is water-based
• Short pot life once mixed (roughly 1–2 hours depending on temperature) demands disciplined batch-by-batch mixing
• Needs sound, properly cured, fully prepared and primed concrete; it will not perform over laitance, oil, damp or weak substrates
• Not a chemical-immersion lining — it resists splashes and spillage of common chemicals, not continuous contact or aggressive concentrated acids
• Full chemical cure takes around 21 days, so heavy chemical exposure should be deferred until cure is complete
• Matt water-based epoxies offer less gloss and chemical resistance than premium solvent-free systems such as Nitoflor SL or polyurethane toppings

Industry use cases

How we position Fosroc Nitoflor EPW100

Within Fosroc’s Nitoflor industrial-flooring range, EPW100 is the entry-level, water-based seal coat — the zero-VOC, odour-free choice when the priority is a clean, dust-free, hygienic floor rather than heavy mechanical or chemical duty. Step up within the same family when the loading demands it: Nitoflor solvent-free self-levelling epoxies (the Nitoflor SL / FC series) give a thicker, harder, glossier high-build floor for production areas, while Nitoflor polyurethane and PU-concrete screeds handle thermal shock, wet processing and aggressive food acids that a thin water-based seal cannot. EPW100 pairs naturally with a Fosroc primer and, where moisture or strength is marginal, with Nitoflor underlayments. Against the wider Indian market, its closest competitors are Sika’s water-based Sikafloor epoxy seal coats (e.g. the Sikafloor-2530/Garage-style water-based systems), MBCC/Master Builders Solutions’ MasterTop water-borne epoxy floor coatings, Dr. Fixit’s epoxy floor coating range from Pidilite, and STP/BASF-legacy and Asian Paints (Apcolite/SmartCare) industrial epoxy systems. Most of these brands offer a comparable low-odour, water-based seal coat, so selection often comes down to local technical support, applicator approval and supply reliability. As an authorised Fosroc distributor and applicator serving Delhi NCR and pan-India, Space Arc Engineering supplies genuine EPW100, advises on the right system tier for your loading, and can recommend the matching primer, preparation and topcoat so the specification holds up in service.
