Fosroc Nitoflor EPU3000
A 3 mm seamless epoxy-polyurethane self-smoothing topping for hard-wearing, hygienic, dust-free industrial and commercial floors.
What is it?
Nitoflor EPU3000 is a Fosroc self-smoothing floor topping that combines epoxy resins, curing agents and graded inert aggregates to lay a nominally 3 mm thick, seamless epoxy-polyurethane (EPU) resin floor. It cures to a hard, impervious, jointless surface that is easy to clean.
Where is it used?
Used inside factories, warehouses, workshops, engineering and assembly plants, food and beverage processing areas, pharmaceutical and packaging facilities, and similar industrial or commercial buildings where a tough, hygienic, dust-free floor is needed.
Why use it?
It is specified where a thin floor screed alone cannot deliver the abrasion resistance, chemical resistance and hygiene a working floor demands. The seamless, impervious finish eliminates dust traps and joints, withstands foot and vehicular traffic, and is straightforward to wash down.
How is it applied?
A trained applicator prepares the concrete (or screed) substrate by mechanical grinding or shot-blasting, primes it, then site-mixes the pre-weighed components and trowels/spreads the topping to a self-smoothing 3 mm finish, working it out to a level, seamless surface before it cures.
About Fosroc Nitoflor EPU3000
Nitoflor EPU3000 is part of Fosroc’s Nitoflor industrial flooring range and is listed in Fosroc’s India product catalogue. It is described by Fosroc as a special blend of selected epoxy resins, curing agents and graded inert aggregates which, when mixed, provides a 3 mm epoxy-polyurethane resin floor topping with self-smoothing laying properties. The result is a hard-wearing, attractive floor that is chemical resistant, impervious and extremely easy to clean.
The product sits in the epoxy self-smoothing topping family alongside other Nitoflor systems such as the Nitoflor SL self-levelling toppings. What distinguishes the EPU (epoxy-polyurethane) chemistry is the blending of epoxy and polyurethane characteristics in a single resin topping, which aims to deliver the toughness and chemical resistance associated with epoxy together with improved surface character. At a nominal 3 mm build, EPU3000 is a true topping rather than a thin film coating, so it bridges minor substrate imperfections and provides a meaningful wear layer rather than a sacrificial paint film.
For specifiers and contractors in India, the appeal is practical. A seamless, jointless monolithic surface removes the dirt-collecting joints and grout lines of tiled or screeded floors, supports wash-down hygiene routines, and stands up to the constant pedestrian and wheeled traffic of a live industrial environment. It is offered in a range of colours, allowing zoning, safety demarcation and a clean, professional appearance across production halls, stores and circulation areas.
As an authorised Fosroc distributor and applicator serving Delhi NCR and Pan-India, Space Arc Engineering supplies Nitoflor EPU3000 together with the matching Fosroc primer and ancillary products, and can advise on substrate suitability, coverage and the right system for a given duty. Because exact technical values and pack configurations are revised from time to time and can vary by region, we always quote against the current Fosroc India Technical Data Sheet for the specific batch and project.
The technical insight
The key technical point to understand about EPU3000 is that it is a self-smoothing topping at a nominal 3 mm build, not a thin protective coating. This matters because Fosroc’s Nitoflor EPU range spans very different products that share a name. Nitoflor EPU100, for example, is a flexible epoxy-polyurethane protective coating applied as a two-coat system at roughly 200 microns per coat for wall/floor protection and waterproofing duty. EPU3000, by contrast, is a heavier, aggregate-filled resin floor laid an order of magnitude thicker, engineered as a trafficked wearing surface. The two are not interchangeable, and figures published for one must never be assumed for the other.
The aggregate loading is what gives EPU3000 its abrasion resistance and load-bearing wear performance. The graded inert fillers carry the mechanical wear while the epoxy-polyurethane resin matrix binds the system, bonds it to the substrate and delivers the chemical and impervious barrier. Because the topping is self-smoothing, it flows out to a level seamless finish during placement, which is why surface preparation and substrate flatness are decisive: any contamination, laitance or unevenness telegraphs through and compromises bond. Sound, clean, dry concrete, mechanically prepared and primed with the recommended Fosroc primer, is the foundation of a durable EPU3000 floor.
Where it is used
- Factory and manufacturing floors subject to continuous foot and wheeled traffic
- Warehouses, stores and despatch areas needing a dust-free, easy-clean surface
- Engineering, assembly and machine shops requiring abrasion and impact resistance
- Food, beverage and dairy processing areas where hygiene and wash-down are critical
- Pharmaceutical, packaging and clean-environment facilities needing a seamless, impervious floor
- Commercial and institutional spaces where a hard-wearing, attractive resin floor is specified
- Areas exposed to occasional chemical spillage requiring a chemical-resistant topping
Key advantages
- Seamless, jointless monolithic finish that eliminates dirt-collecting joints and is easy to clean
- Self-smoothing application flows out to a level, attractive surface
- Hard-wearing with good abrasion resistance for foot and vehicular traffic
- Impervious and chemical resistant, suiting hygienic and wash-down environments
- Nominal 3 mm build provides a genuine wear layer, not just a thin film
- Available in a range of colours for zoning, demarcation and appearance
- Backed by Fosroc’s pan-India technical support and a matched primer/ancillary system
Limitations & considerations
- Requires thorough mechanical surface preparation (grinding/shot-blasting) and priming; bond fails on contaminated or weak substrates
- Concrete must be sound, dry and adequately cured (typically 28 days) with controlled moisture before application
- Best installed by trained resin-flooring applicators, not as a general-trades DIY product
- Like most epoxy-based resins, the surface can chalk or lose gloss under prolonged direct UV/sunlight, so it is primarily an interior product
- Not a structural repair or levelling layer; gross substrate falls or defects must be corrected first
- Cure and over-coating times are temperature dependent and slow in cold conditions; site temperature and humidity must be managed
- Exact performance values and chemical-resistance limits must be confirmed against the current Fosroc TDS for the intended exposure
Selection & best practice
Lay Nitoflor EPU3000 at its nominal 3 mm thickness over sound, clean, dry concrete that is fully cured (typically at least 28 days) with surface moisture within Fosroc’s limits. Remove laitance and contamination by mechanical grinding or shot-blasting to an SA 2.5 standard on steel or a sound mechanically-prepared profile on concrete, then prime with the Fosroc-recommended primer before placing the topping. Site-mix the pre-weighed components fully and respect the pot life, which shortens at the higher ambient temperatures common across India, so plan batch sizes and gang size to place each mix within working time. Maintain substrate and air temperature within the datasheet range, protect the fresh floor from dust, water and traffic until it has reached the specified cure, and confirm the project-specific coverage, pack quantity and chemical-resistance schedule against the current Fosroc India Technical Data Sheet before ordering.

How we position Fosroc Nitoflor EPU3000
Within Fosroc’s own range, Nitoflor EPU3000 sits in the epoxy self-smoothing topping family and is a close sibling to the Nitoflor SL self-levelling epoxy toppings (such as the Nitoflor SL series), which solve a similar 2-3 mm seamless-floor brief; the EPU chemistry is chosen where the epoxy-polyurethane blend is preferred. It should not be confused with thinner Nitoflor coatings like EPU100 or the Nitoflor FC floor coatings (100-500 micron films), nor with the heavier trowel-applied screeds such as Nitoflor TF for very aggressive chemical and mechanical duty. For environments with severe thermal shock, steam cleaning or aggressive chemical loading, a PU-cementitious system (Fosroc’s Nitoflor Floorcrete PU, or comparable PU screeds from other manufacturers) is usually the more appropriate choice than an epoxy-PU topping. Among credible alternatives from other brands, contractors commonly weigh Sika Sikafloor self-smoothing epoxy systems and MBCC/Master Builders Solutions MasterTop epoxy toppings for like-for-like duty, while Ucrete (the polyurethane-cementitious benchmark) is the reference where extreme thermal and chemical resistance is required. As an authorised Fosroc distributor and applicator in Delhi NCR and Pan-India, Space Arc Engineering recommends EPU3000 where a hard-wearing, hygienic, seamless 3 mm interior floor is the goal, and will steer specifiers to the right Nitoflor or alternative system when the exposure calls for it.
