About Fosroc Nitoflor TF10000

Fosroc Nitoflor TF10000 is the heavy-duty member of the Nitoflor trowel-applied epoxy screed range, engineered for floors that take punishment ordinary concrete and thin coatings cannot survive. It is supplied as a three-component system: an epoxy resin base, a modified polyamine hardener, and a specially selected and graded silica aggregate of high crushing strength. The components arrive in pre-weighed units, so the applicator simply mixes the full kit on site and lays it — there is no batching or guesswork on the resin-to-aggregate ratio.

What distinguishes TF10000 from lighter screeds is the build thickness. It is trowel-applied from 5 mm for light-to-medium wear right up to 10 mm for the most aggressive industrial duty, where the extra mass absorbs impact, resists gouging from dragged loads, and bridges minor substrate irregularities. The cured floor is seamless and impervious, eliminating the joints and porous patches where chemicals, water and bacteria normally attack a floor. Because the polyamine curing agent and the inert silica aggregate are both chosen for chemical durability, the topping shrugs off the acids, alkalis, oils, solvents and salt solutions routinely spilled in process plants.

For Indian specifiers, TF10000 sits above products like Nitoflor TF5000 (a 3-6 mm screed) where the duty cycle is more severe and a thicker, tougher wearing course is justified. It is always laid as a system — primer plus screed — and can be over-sealed with a Nitoflor FC-range epoxy coating where a closed, ultra-hygienic or coloured finish is wanted. Space Arc Engineering supplies and applies TF10000 across Delhi NCR and Pan-India as an authorised Fosroc distributor and applicator, with substrate assessment, surface preparation and laying handled by trained crews so the system performs as designed.

The technical insight

The performance of TF10000 comes from three design choices working together. First, the modified polyamine (rather than a standard amine) hardener gives the cured matrix its broad chemical resistance — polyamine-cured epoxies tolerate dilute acids, alkalis, oils and solvents far better than general-purpose systems, which is why the floor survives in plating, battery and refinery environments. Second, the graded high-crushing-strength silica aggregate is what carries the mechanical load: the resin binds and protects, but it is the densely packed quartz that resists abrasion and point loading, giving a screed whose compressive and abrasion performance comfortably exceeds the concrete beneath it. Third, the system is solvent-free and trowel-compacted, so there is no solvent flash-off porosity and no shrinkage voids — the topping is genuinely impervious. The practical consequence for a contractor is that everything depends on the bond to the substrate and on compaction. The substrate must be sound, dry and mechanically prepared (grit-blasting or scabbling, not just acid etch) and primed with Nitoprime 30/31 while still tacky; the mortar must be tamped and trowelled to full compaction within its pot life. Get the preparation, priming window and compaction right and the floor is monolithic with the slab; get them wrong and even a premium screed will debond — which is why TF10000 is best treated as an applied system, not just a bagged product.

Where it is used

• Heavy engineering, fabrication and machine shops with hard-wheeled and forklift traffic
• Steelworks, foundries and metal-forming areas subject to impact and abrasion
• Chemical process, handling and storage areas exposed to acid, alkali and solvent spillage
• Oil refineries, petrochemical units and paint/solvent workshops
• Battery charging rooms and electroplating factories (acid and electrolyte exposure)
• Breweries, distilleries, dairies, sugar and food-processing plants needing impervious, washable floors
• Loading docks, ramps and dispatch bays carrying point loads and trolley traffic
• Areas of lighter duty where above-average durability and low maintenance justify a thick epoxy screed

Key advantages

• Extreme durability — withstands heavy loads and high abrasion, outperforming the concrete substrate
• Broad chemical resistance from the modified polyamine cure across acids, alkalis, oils, solvents and salts
• Thick 5-10 mm build absorbs impact and bridges minor substrate defects that thin coatings cannot
• Seamless and impervious, removing joints and porous zones where failure and contamination start
• Safe non-slip finish for both pedestrian and vehicular traffic
• Solvent-free and low odour — no harmful solvent vapours during laying, suited to enclosed plants
• Supplied in pre-weighed units for accurate, repeatable site mixing with no batching errors
• Can be over-sealed with Nitoflor FC-range coatings for hygienic, coloured or closed finishes

Limitations & considerations

• Trowel-applied screed requiring skilled applicators — not a DIY or roller-applied product
• Substrate must be sound, dry (concrete typically 28 days old, moisture below ~5%) and mechanically prepared; acid etching alone is usually inadequate
• Mandatory priming with Nitoprime 30/31 and application within the primer overlay window
• Limited working time once mixed — material must be placed and compacted within pot life or be discarded
• Epoxy resins and hardeners can sensitise skin; gloves, eye protection and ventilation are required
• Continuous high-temperature exposure is limiting — epoxy screeds soften at sustained elevated temperatures (for thermal-shock or steam-cleaned zones a polyurethane screed may be more suitable)
• Some strong oxidising acids cause discolouration or are only suited to occasional-spillage areas with good housekeeping
• Cost and labour are higher than thin-film coatings; justified by duty cycle, not chosen by default

How we position Fosroc Nitoflor TF10000

Within the Fosroc range, Nitoflor TF10000 is the top of the trowel-applied epoxy screed ladder: a step up in thickness and duty from Nitoflor TF5000 (3-6 mm), and well above thin-film systems such as the Nitoflor FC-range epoxy coatings (FC130/FC140/FC150) or self-levelling Nitoflor SL grades, which are better suited to lighter wear and decorative or hygienic finishes — and which can be used as a sealer coat over TF10000 itself. It pairs with Nitoprime 30/31 primer as a complete system. Where the real requirement is thermal-shock or steam-clean resistance, a polyurethane (PU) screed is the more appropriate Fosroc choice than this epoxy mortar. Against the wider Indian market, credible alternatives a specifier may evaluate include Sika’s heavy-duty epoxy mortar screeds (Sikafloor range), MYK Arment / MBS and STP (Shalimar/STP) epoxy flooring systems, and, for lighter or repair-oriented duty, Dr. Fixit (Pidilite) floor coatings — though Dr. Fixit’s strength is waterproofing rather than heavy industrial screeds. TF10000’s edge is its proven heavy-duty epoxy-mortar pedigree and the fact that, with Space Arc as authorised distributor and applicator, it is delivered as a prepared-and-laid system rather than a bag of product, which is what ultimately determines floor life.
