Fosroc Nitoflor Uremax
A two-component polyurethane floor coating that seals, protects and colours industrial concrete against traffic, chemicals and daily wash-downs.
What is it?
A two-component polyurethane (PU) floor coating from Fosroc’s Nitoflor range, applied as a thin protective and decorative film over prepared concrete.
Where is it used?
Warehouses, engineering workshops, food and beverage units, pharmaceutical areas, loading bays and vehicle service floors that need a clean, sealed, chemical-resistant surface.
Why use it?
It turns porous, dusting concrete into a hard-wearing, easy-to-clean and colour-coded floor without the cost or downtime of a full screed system.
How is it applied?
Roller, brush or notched squeegee applied over a shot-blasted or ground concrete substrate that has been primed, usually in one or two coats.
About Fosroc Nitoflor Uremax
Nitoflor Uremax sits in Fosroc’s Nitoflor family of industrial floor treatments, alongside the heavier PU-cement toppings and epoxy systems specifiers already know. It is a two-component polyurethane coating: a resin base and a hardener that are mixed on site and cure to form a tough, seamless film bonded to the concrete below. Rather than rebuilding the floor slab, it works on the top few tenths of a millimetre — sealing the surface, killing dust and giving the client a coloured, wipe-clean finish that holds up to forklift traffic, spills and routine washing. For a distributor-applicator like Space Arc, it is the go-to when a facility wants a clear performance upgrade over bare concrete but does not need the thickness of a trowelled screed.
Because it is a coating rather than a topping, Uremax is fast to lay and quick to return to service, which matters on live sites where a warehouse aisle or a process bay can only be closed for a weekend. The trade-off is that it protects the concrete rather than replacing worn concrete, so the condition and preparation of the existing slab largely decide how long the finish lasts. Applied over sound, properly prepared and primed concrete, it delivers a genuinely industrial floor; applied over weak or contaminated concrete, no coating in the market will perform. Space Arc supplies the product and, where required, applies it — so the specification, surface preparation and coating are handled as one accountable package across Delhi NCR and Pan-India.
The technical insight
The performance comes from the polyurethane chemistry. When the two components are mixed, the isocyanate hardener reacts with the resin’s hydroxyl groups to build a cross-linked polymer network. That network is what gives PU coatings their characteristic combination of hardness and flexibility — the film is tough enough to resist abrasion and point loads from wheels and pallets, yet elastic enough to absorb minor substrate movement and thermal cycling without cracking, where a more rigid coating might. The same dense, cross-linked film is what makes the surface chemically resistant and non-porous: liquids, oils and cleaning agents sit on top instead of soaking into the concrete, so the floor cleans down easily and does not harbour contamination. Polyurethanes also hold colour better than many epoxies under light exposure, which is why PU is often specified where a stable appearance matters. None of this can be bought at the mixing bucket, though — the coating only develops full strength and adhesion if it is applied to clean, dry, mechanically prepared concrete with the correct primer, because the bond to the substrate is the weakest link in any thin-film system.
Where it is used
- Warehouse and distribution floors carrying forklift and pallet-truck traffic
- Engineering and assembly workshops exposed to oils, coolants and dropped tools
- Food and beverage production and packing areas needing a sealed, wash-down surface
- Pharmaceutical and clean-room floors where dust-free, easily sanitised surfaces are essential
- Loading docks, dispatch bays and hardstand areas subject to constant wheeled loads
- Vehicle service and maintenance workshops exposed to fuels, greases and hydraulic fluids
- Colour-coded walkways and demarcated zones for safety and traffic management
- Sealing and refurbishing existing concrete floors that are dusting or losing surface
Key advantages
- Seamless, non-porous finish that resists dust, spills and bacterial harbourage
- Good chemical resistance to oils, fuels and many cleaning agents used in industry
- Combination of hardness and flexibility that resists abrasion while tolerating minor movement
- Colour stability and good appearance retention compared with many epoxy coatings
- Fast application by roller, brush or squeegee with relatively quick return to service
- Available in a range of colours for aesthetics and zone demarcation
- Lower installed cost and thickness than a full PU-cement or epoxy screed system
- Backed by Fosroc’s established Nitoflor range and Space Arc’s applicator support
Limitations & considerations
- A thin coating protects the concrete but cannot rebuild a worn, weak or heavily damaged slab — a topping or screed is needed for that
- Final performance and durability depend heavily on surface preparation and priming; it will fail on laitance, oil-contaminated or damp concrete
- Not a substitute for heavy-duty PU-cement systems where severe impact, thermal shock or steam cleaning is expected
- Requires application within defined temperature and humidity limits, and a suitably dry substrate, so timing on site matters
- Chemical resistance is broad but not universal — the specific chemicals and concentrations on site must be checked against the manufacturer’s resistance data
- Being a two-component product, it has a limited pot life once mixed and must be used promptly by trained applicators
Selection & best practice
Success with a thin-film PU coating is decided before the first coat goes down. Start by assessing the concrete: it must be sound, clean and dry, with surface laitance removed by shot-blasting or diamond grinding to expose a mechanically keyed profile. Check that the slab is genuinely dry — trapped moisture is the most common cause of coating failure — and confirm the substrate meets the moisture limits in the datasheet before proceeding. Repair spalls, cracks and low spots with a compatible Fosroc repair mortar first, then apply the recommended polyurethane-compatible primer to lock down the surface and promote adhesion. Mix each unit fully and in the correct ratio — never split kits by eye — and apply within the pot life, working to a wet edge to avoid lap marks. Respect the manufacturer’s temperature, humidity and overcoating windows, and protect the fresh floor from traffic and water until it has cured. On any critical or large project, involve Space Arc’s applicators early so the specification, preparation and application are aligned rather than corrected after the fact.

How we position Fosroc Nitoflor Uremax
Nitoflor Uremax is the entry point into Fosroc’s Nitoflor industrial-flooring range — the thin-film PU coating you specify when sound concrete needs sealing, colouring and chemical protection rather than rebuilding. When the floor itself is worn, or the environment involves heavy impact, thermal shock or steam cleaning, step up within the same family to Fosroc Nitoflor SL3000 U, the flow-applied PU-cement topping laid at 3-6 mm. For appearance-led or lighter-duty areas, an epoxy self-levelling system may be the more economical answer, and for surface repairs before coating we pair it with Fosroc’s Nitomortar/Renderoc repair mortars. Across other brands we stock, comparable industrial-floor coatings from MC-Bauchemie and Sika can be specified where a client has a standing preference; Space Arc’s role is to match the system to the substrate, traffic and budget rather than push a single product.
