About Fosroc Nitoflor UR108

Fosroc Nitoflor UR108 is a two-component polyurethane floor coating that sits within Fosroc’s Nitoflor industrial-flooring family. It is supplied as a base and a hardener that are blended on site immediately before use; the cured film bonds to concrete and cementitious surfaces and converts a bare, dusting slab into a tougher, sealed and far more serviceable floor. The defining purpose of the product is durability – it raises the abrasion and wear resistance of the surface it protects, while also standing up to common automotive and workshop chemicals such as petrol, diesel and lubricating oils.

For Indian contractors, consultants and facility owners, UR108 belongs to the category of thin-film, two-pack floor coatings rather than thick self-levelling toppings. That distinction matters when specifying. A coating like this is the right answer where the concrete is structurally sound but needs sealing, dust-proofing, a wearing layer and chemical protection – not where you need to rebuild levels, bridge cracks structurally or resist heavy impact and thermal shock (those call for screed-grade epoxy or polyurethane-cement systems instead). Polyurethane chemistry, as opposed to standard epoxy, generally brings better flexibility, abrasion toughness and resistance to fuels and oils, which is exactly the profile Fosroc positions UR108 for.

Space Arc Engineering supplies and applies Nitoflor UR108 as an authorised Fosroc distributor and applicator across Delhi NCR and Pan-India. Because published India-specific datasheet figures (exact coverage, pack size and cure schedule) should be read from the current Fosroc TDS at the time of order, we always confirm the latest values with Fosroc before locking a specification or BOQ – the chemistry and intended use, however, are well established and summarised on this page.

The technical insight

UR108 is a reactive polyurethane: the base resin and the isocyanate-functional hardener crosslink on mixing to form a continuous, chemically cured film bonded to the concrete. That crosslinked PU network is what delivers the two headline properties Fosroc cites – high abrasion/wear strength and resistance to petrol, diesel and lubricating oils. The practical consequence is that the floor stops dusting, becomes washable and resists the rubbing and point-loading of light traffic far better than sealed or untreated concrete. As a thin-film coating it does not add meaningful build or correct level; performance is governed almost entirely by substrate soundness, moisture and surface preparation. Concrete must be at least 28 days old, sound, clean and dry, with laitance and contamination removed (mechanical preparation such as grinding or shot-blasting is standard), and the slab must have an effective damp-proof membrane – residual rising moisture is the most common cause of adhesion failure in any two-pack floor coating. A compatible Fosroc primer is normally used to seal the prepared concrete and promote adhesion before the UR108 coats are applied. Because exact figures vary by edition, always confirm coverage, film thickness, number of coats, pot life, overcoat window and full-cure time against the current Fosroc Nitoflor UR108 datasheet for the batch supplied.

Where it is used

• Sealing and dust-proofing of bare concrete floors in warehouses, godowns and storage areas
• Workshop, service-bay and garage floors exposed to petrol, diesel and lubricating oils
• Light-to-medium-duty industrial production and assembly floors with foot and light wheeled traffic
• Plant rooms, utility rooms and machine areas needing an easy-to-clean wearing surface
• Covered parking, basement and loading-dock floors requiring abrasion resistance and oil resistance
• Refurbishment of existing dusting or worn concrete where a thin protective coating is sufficient

Key advantages

• Two-component polyurethane chemistry gives a tough, durable wearing film
• High abrasion and wear resistance that hardens and protects the concrete surface
• Resists petrol, diesel and lubricating oils – well suited to workshop and vehicle areas
• Seals porous concrete, eliminating surface dusting and making floors washable
• Bonds to concrete and cementitious substrates as a thin, economical protective layer
• Supplied in pre-weighed packs, reducing on-site mixing error
• Roller/brush applied, allowing relatively fast turnaround on light-to-medium-duty floors
• Backed by Fosroc’s pan-India technical support and authorised applicator network

Limitations & considerations

• A thin-film coating – it does not build thickness, correct levels or bridge structural cracks
• Light-to-medium-duty by nature; heavy impact, gouging or steel-wheel traffic call for thicker epoxy or PU-cement screeds
• Not a thermal-shock or steam-clean floor; polyurethane-cement systems (e.g. Nitoflor floorcrete-type products) are the correct choice there
• Performance depends heavily on substrate preparation, soundness and dryness; rising damp causes adhesion failure
• Requires concrete cured 28 days minimum and an effective damp-proof membrane beneath the slab
• Pot life is limited once mixed; component ratios and working time must be followed exactly
• Like most two-pack PU coatings it needs ventilation and PPE during application and a controlled cure environment
• Aromatic polyurethanes can chalk/yellow under direct UV – confirm UV suitability with Fosroc for exposed external use

How we position Fosroc Nitoflor UR108

Within Fosroc’s own Nitoflor range, UR108 is a thin-film polyurethane wearing coat – a step up from sealing a slab but lighter than the thicker systems. If your floor needs a built-up self-levelling layer, look at Fosroc’s epoxy toppings such as the Nitoflor SL/FC series; for harsh thermal-shock or wet/steam-clean process areas, a polyurethane-cement screed like the Nitoflor Floorcrete PU family is the correct heavy-duty choice, and clear/decorative or light-duty needs may point to Nitoflor PUW100 or FC-series coatings. Against the wider Indian market, UR108 competes with two-pack PU and epoxy floor coatings from Sika (e.g. Sikafloor PU/epoxy coatings), MBCC/Master Builders Solutions (MasterTop coatings), Dr. Fixit (Pidilite’s flooring line) and STP. Those alternatives are all credible; the deciding factors are duty level, chemical exposure, substrate condition, lead time and applicator support. Space Arc’s role is to match the floor to the right product rather than default to one – we recommend UR108 where a durable, oil- and fuel-resistant, light-to-medium-duty PU coating is genuinely the best fit, and we will steer you to a heavier or more specialised Fosroc system (or honestly compare an equivalent Sika/MBS/Dr. Fixit/STP product) when your conditions demand it.
