About Fosroc Nitoflor FC140

Nitoflor FC140 is Fosroc’s workhorse solvent-based epoxy floor coating, made for the many industrial floors that do not need a thick resin screed but do need protection the bare concrete cannot give on its own. It is a two-component system: a pigmented epoxy base and a hardener that are blended on site immediately before use. Once cured, the film locks out the moisture, oils and aggressive liquids that would otherwise soak into porous concrete, dust it up and slowly eat away the surface. Because the coating sits as a thin film rather than a heavy overlay, it is one of the more economical ways to turn a plain slab into a sealed, wipe-clean working floor.

Space Arc Engineering supplies and applies FC140 as an authorised Fosroc distributor and applicator across Delhi NCR and on projects Pan-India. In practice we see it specified where a plant wants a tidy, colour-coded, chemical-tolerant floor without the cost or downtime of a self-levelling build-up: food and beverage units, pharma support areas, engineering workshops and back-of-house commercial spaces. It also does double duty as the coating-and-sealer layer over Fosroc’s Cemtop cementitious flooring, tying the two systems together. What FC140 is not is a heavy-duty screed for forklift-battered warehouse aisles; for that traffic a thicker system is the right call, and we will say so rather than oversell the film.

The technical insight

The performance comes from the cured epoxy network itself. When the base and hardener are mixed in the correct ratio, the amine hardener cross-links the epoxy resin into a dense, tightly bonded film with very low porosity. That closed structure is what gives FC140 its chemistry: aggressive liquids sit on the surface instead of wicking into the concrete, so acids, alkalis, oils and many industrial chemicals are resisted rather than absorbed. The same low porosity is what makes the floor hygienic and easy to clean, because there are no open pores for grease, dyes or bacteria to lodge in. Being solvent-based, the resin carries in a solvent that flashes off as the film forms, which is why the coating lays down thin and even at around 90 microns over two coats and wets into the substrate well. That thin-film nature is a deliberate trade-off: it protects and seals the surface chemically and hygienically, but it relies entirely on a sound, correctly prepared concrete base to carry mechanical load, since the film has little thickness of its own to absorb heavy impact or gouging.

Where it is used

• Production and assembly areas where floors need a clean, sealed, chemical-tolerant surface
• Dairies, breweries and soft-drink bottling plants subject to frequent wet washdown
• Commercial kitchens and food-preparation areas requiring a hygienic, easily cleaned floor
• Plating shops, processing plants and dye works where chemical spillage is likely
• Engineering workshops and light industrial units needing dust-free, wipe-clean floors
• Showrooms and commercial spaces where an attractive coloured finish matters
• As a coating and sealer over Cemtop industrial and commercial cementitious flooring
• Colour-coded demarcation of gangways, bays and safety zones within a plant

Key advantages

• Hard-wearing film that lowers maintenance costs on floors that would otherwise dust and erode
• High resistance to a wide range of industrial chemicals, acids, alkalis and oils
• Impervious, low-porosity finish that stays hygienic and washes down easily
• Available in a range of colours to brighten the working environment and aid zoning
• Thin-film system, so it is economical compared with self-levelling epoxy build-ups
• Semi-gloss appearance that lifts the look of plant, showroom and back-of-house floors
• Doubles as the sealer coat for Fosroc Cemtop cementitious flooring systems
• Backed by Space Arc’s local supply and in-house application across Delhi NCR and Pan-India

Limitations & considerations

• A thin film at around 90 microns, so it is not a heavy-duty screed for constant forklift or steel-wheel traffic
• Solvent-based, so application areas must be well ventilated and kept away from ignition sources until cured
• Performance depends entirely on sound, correctly prepared and primed concrete; it will not bridge a weak or contaminated slab
• The substrate must be dry, as trapped moisture or a high water table can lift or blister the film
• Colour uniformity should be confirmed with a site trial area before full application, and coloured floors need consistent batching

How we position Fosroc Nitoflor FC140

Nitoflor FC140 sits in the light-to-medium duty end of Fosroc’s flooring range: a chemical-resistant, hygienic seal coat for existing concrete rather than a structural overlay. Where a floor needs mechanical hardness built into fresh concrete instead, Fosroc Nitoflor Hardtop is the natural companion, and for a moisture-barrier primer under sensitive finishes we pair it with Fosroc Nitocote VF. For genuinely heavy-duty or self-levelling requirements, or where a solvent-free build-up is mandated, we also carry thicker Fosroc epoxy flooring systems and, across our other brands, industrial flooring solutions from Sika and MC-Bauchemie. Space Arc can advise on the right specification for the traffic, chemistry and downtime your floor actually faces.
