About Fosroc Nitoflor EPU2000

Fosroc Nitoflor EPU2000 is a self-smoothing epoxy-polyurethane floor topping from Fosroc’s high-technology Nitoflor flooring range. It is a factory-blended system of selected epoxy resins, curing agents and graded inert fillers that, once mixed and poured, flow out to form a continuous resin floor at roughly 1.6 to 2 mm thickness. Because the material levels under its own weight, it produces a smooth, jointless surface without the trowel marks and texture variation associated with hand-applied screeds.

The product sits in the flow-applied (“self-levelling”) family of the Nitoflor portfolio, alongside the purely epoxy Nitoflor SL series. What distinguishes EPU2000 is the polyurethane component blended with the epoxy, which gives the cured floor a tougher, slightly more forgiving film while retaining the clean, glossy aesthetic facilities managers expect from a resin floor. The system is designed as a complete build-up: the prepared concrete is first sealed with Nitoprime 25, a two-part epoxy primer supplied in matching pre-weighed packs, and the EPU2000 topping is then laid over it.

For Indian facilities, EPU2000 is positioned as a mid-build, premium-finish floor for areas that need to be visibly clean and genuinely hygienic rather than simply hard-wearing. It is widely specified in pharmaceutical manufacturing, food and beverage processing, hospital and laboratory clean rooms, electronics assembly and similar controlled environments where a dust-free, seamless, easily sanitised floor is a regulatory and operational requirement. Space Arc Engineering supplies and applies EPU2000 as an authorised Fosroc distributor and applicator, covering Delhi NCR and Pan-India projects.

The technical insight

The “EPU” designation reflects the hybrid chemistry: an epoxy backbone modified with polyurethane. Pure epoxy self-levellers are hard and chemically robust but can be brittle and prone to a slightly yellowed, glassy film; adding a PU component improves toughness and impact tolerance and keeps the finish cleaner-looking over time. This makes EPU2000 a sensible step up from a basic epoxy SL floor where the client wants both hygiene and a degree of resilience, but does not need the extreme thermal-shock and steam resistance of a heavy-duty PU-cement screed such as Nitoflor TF120 UB. Two specification details matter most in practice. First, the build is thin (nominally 2 mm), so it is a topping, not a screed — it follows and relies on the substrate beneath it, and the concrete base should have adequate strength (Fosroc’s flooring guidance recommends a substrate compressive strength of at least 25 MPa for resin floor treatments) and be properly prepared. Second, it is part-of-a-system: the Nitoprime 25 epoxy primer is integral to adhesion, and skipping or under-applying the primer is the single most common cause of debonding on site.

Where it is used

• Pharmaceutical manufacturing and packaging halls requiring GMP-grade hygienic floors
• Food and beverage processing, dairy and confectionery dry-process areas
• Hospital clean rooms, operation-theatre support areas and laboratories
• Electronics and switchgear assembly plants and instrument rooms
• Showrooms, display areas and light-industrial production floors
• Corridors, gowning rooms and finished-goods storage in controlled facilities

Key advantages

• Self-smoothing formulation flows to a seamless, level finish with minimal applicator effort
• Jointless, pore-free surface is dust-free and very easy to clean and sanitise
• Good resistance to abrasion from foot and light vehicular (trolley/pallet-truck) traffic
• Very good resistance to many industrial chemicals encountered in pharma and food plants
• Supplied in pre-weighed packs, reducing on-site mixing errors and speeding application
• Available in a wide range of colours for zoning, branding and a clean appearance
• Fast, neat installation lowers labour cost and downtime versus hand-trowelled screeds

Limitations & considerations

• A 2 mm topping, not a heavy screed — unsuitable for heavy forklift loads, point impact or thermal-shock duty (use a PU-cement screed instead)
• Performance depends on the substrate; concrete must be sound, dry and adequately strong (around 25 MPa minimum) before laying
• Must not be applied when temperature is below 10C or expected to fall below 10C within 24 hours
• Substrate moisture should typically be below 75% relative humidity; damp slabs need a moisture-tolerant primer or remediation
• Requires the Nitoprime 25 epoxy primer as part of the system — omitting it risks debonding
• Epoxy-based topping can gradually yellow or chalk under strong direct UV, so it is intended for interior use
• Self-levelling resin floors are smooth by nature; a slip-resistant aggregate broadcast should be specified for wet or sloped areas

How we position Fosroc Nitoflor EPU2000

Within the Fosroc Nitoflor range, EPU2000 occupies the middle ground of flow-applied resin floors: more resilient than a basic epoxy self-leveller such as Nitoflor SL2000/SL3000, but lighter-duty than heavy PU-cement screeds like Nitoflor SL3000 UT or Nitoflor TF120 UB, which are the right choice for forklift-heavy, wet-process, steam-cleaned or thermal-shock environments. Where a thicker, more abrasion-resistant epoxy screed is needed, Nitoflor TF5000 is the natural step up, and conductive areas would move to the Nitoflor SL Conductive/Dissipative system. Against competitor products, EPU2000 is comparable to self-smoothing epoxy/PU toppings in the Sika Sikafloor range (for example the Sikafloor self-levelling epoxy systems) and the MBCC/Master Builders Solutions MasterTop epoxy floors, while genuinely heavy-duty hygienic duty is the domain of PU-cement systems such as Ucrete. For most pharma, food and clean-room interiors that need a seamless, hygienic, good-looking floor without extreme mechanical or thermal demands, EPU2000 is a well-matched, cost-effective specification — and as an authorised Fosroc distributor and applicator, Space Arc Engineering can advise honestly on when a heavier screed is the better long-term investment.
