Fosroc Nitoflor Sol
The dedicated cleaning solvent that keeps Fosroc Nitoflor epoxy and polyurethane flooring applications running clean – for tools, rollers, mixers and spillages.
What is it?
Nitoflor Sol is a flammable solvent / thinner-grade cleaning agent from Fosroc, not a floor topping itself. It is the companion product specified across the Nitoflor flooring range for cleaning tools and equipment immediately after applying solvented epoxy and PU systems.
Where is it used?
On every Fosroc Nitoflor flooring site – warehouses, factories, pharma and food plants, workshops and car parks – wherever solvented epoxy/PU coatings such as Nitoflor EU5, FC150 or FC140 are being applied and equipment must be cleaned before resin cures.
Why use it?
Cured epoxy and PU resins cannot be removed once hardened. Nitoflor Sol dissolves uncured resin from rollers, squeegees, trowels and mixing paddles so expensive tools are reused and spillages are controlled, protecting both the applicator and the finish.
How is it applied?
Wipe or wash tools and equipment with Nitoflor Sol immediately after use; absorb spillages with sand or sawdust. It is a cleaner/thinner – never a wearing surface – and is handled with gloves, goggles and ventilation away from naked flame.
About Fosroc Nitoflor Sol
Nitoflor Sol is one of the most frequently specified yet least understood items in the Fosroc Nitoflor flooring family. It is not an industrial floor topping, screed or coating – it is the ancillary cleaning solvent that Fosroc names throughout its Nitoflor technical data sheets as the approved means of cleaning tools and equipment after a solvented epoxy or polyurethane floor coating has been applied. On a real flooring site it sits in the corner next to the resin packs, and the quality of the finished floor often depends on whether the crew used it correctly. Space Arc Engineering, as an authorised Fosroc distributor and applicator across Delhi NCR and Pan-India, supplies Nitoflor Sol alongside the flooring systems it serves so that contractors are never caught short mid-pour. Because two-part epoxy and PU resins have a finite pot life and become permanently insoluble once they cure, every roller, squeegee, notched trowel, spiked roller, mixing paddle and drill-mounted stirrer used in the application must be cleaned within minutes of finishing a batch – and that window is exactly what Nitoflor Sol is formulated for. Fosroc’s TDS instruction is consistent and unambiguous: All tools and equipment should be cleaned immediately after use with Nitoflor Sol. The same documents specify it for absorbing and managing spillages of uncured product. Understanding its true role matters commercially as well as technically. Contractors who treat Nitoflor Sol as an afterthought routinely lose costly application kit to hardened resin, or worse, attempt to thin the flooring resin with it – which Fosroc explicitly prohibits on its solvent-free systems (the FC150 datasheet states Do not add solvent thinners at any time). Procurement teams in India often buy the flooring resin and primer but forget the cleaning solvent, then improvise with random thinners that leave residues and compromise inter-coat adhesion on the next bay. Specifying genuine Nitoflor Sol removes that risk, keeps the system within Fosroc’s warranted method statement, and is a small line item that protects a large flooring contract. For architects, consultants and facility owners, the presence of Nitoflor Sol in the bill of quantities is a quiet signal that the applicator intends to follow Fosroc’s method correctly rather than cut corners on housekeeping.
The technical insight
Nitoflor Sol is a low-flash organic solvent blend (flash point 33C, classifying it as a flammable liquid) engineered to dissolve uncured epoxy and polyurethane resins. Its chemistry is matched to the Nitoflor binder systems so it cuts wet resin film fast without leaving a greasy residue that would interfere with subsequent coats. The critical technical distinction every applicator must hold is that Nitoflor Sol is a cleaning solvent and not a thinner for the flooring resin itself – Fosroc’s solvent-free Nitoflor coatings (FC150, FC150 HP, EU5 and similar) are formulated at a fixed mix ratio and pot life, and adding any solvent to the mix changes viscosity, cure profile, film build and chemical resistance. The correct workflow is: mix and apply the resin neat, then immediately decant unused product, scrape containers clean, and flush tools with Nitoflor Sol before the resin gels. Because of its 33C flash point it must never be used near naked flame, sparks or hot work, containers must be resealed when not in use, and adequate ventilation or breathing apparatus is required in enclosed bays. Spillages should be absorbed with sand or sawdust and disposed of per local waste regulations rather than flushed to drains. Skin contact is washed off immediately with soap and water. None of these are optional best-practices – they are lifted directly from Fosroc’s published health, safety and fire guidance for the product.
Where it is used
- Cleaning rollers, brushes, squeegees and pile applicators immediately after applying Nitoflor epoxy and PU floor coatings
- Cleaning notched trowels, spiked/spreader tools and screeding rakes used to lay self-levelling and screed systems
- Flushing drill-mounted paddle mixers and mixing vessels between resin batches before the resin gels
- Absorbing and controlling spillages of uncured resin during application (with sand or sawdust)
- Degreasing and removing wet resin smears from adjacent surfaces, edges and skirting before they cure
- Site housekeeping and tool maintenance on multi-day industrial flooring projects where the same kit is reused daily
Key advantages
- Purpose-matched to Fosroc Nitoflor resins, so it cleans wet epoxy/PU film quickly and cleanly without leaving adhesion-killing residue
- Keeps the application within Fosroc’s warranted method statement – genuine Nitoflor Sol is the named cleaner in the TDS, protecting system guarantees
- Saves expensive application tools (spiked rollers, notched trowels, paddle mixers) from being lost to permanently hardened resin
- Readily available in practical 5 and 20 litre cans to suit small fit-outs or large multi-bay industrial floors
- Simple, predictable solvent with no mixing – one product covers cleaning across the whole solvented Nitoflor range
- Supplied by Space Arc alongside the flooring system, so crews are never forced to improvise with unsuitable local thinners
Limitations & considerations
- It is NOT a floor topping, coating, sealer or hardener – it provides no wearing surface and is never applied to the finished floor
- Flammable (flash point 33C) – cannot be used near naked flame, sparks, hot work or while smoking, and needs good ventilation
- Must NOT be added to solvent-free Nitoflor resins as a thinner; doing so voids cure and chemical-resistance performance
- Solvent vapours require ventilation or breathing apparatus in enclosed areas; some users are sensitive to solvents
- Requires careful flammable-liquid storage (resealed containers, cool dry place away from ignition) and compliant disposal of spillage waste
- Effective only on uncured resin – once epoxy/PU has hardened on tools it must be removed mechanically, not with Nitoflor Sol
Selection & best practice
Clean tools with Nitoflor Sol immediately after each batch – never wait until the end of the day, because epoxy and PU gel within the pot life and become impossible to remove once cured. Keep a dedicated, clearly labelled flammable-liquids zone on site with the cans resealed when not in use, well away from any naked flame, grinding or hot work, and ensure cross-ventilation in enclosed bays. Decant only what is needed for cleaning into a separate vessel rather than dipping dirty tools into the main can, which keeps the bulk solvent clean for longer. Absorb any spillage of uncured resin with sand or sawdust, transfer to a sealed vessel, and dispose of per local regulations – do not pour to drains. Crucially, brief the crew that Nitoflor Sol is a cleaner only: it must never be tipped into the flooring resin to make it flow, as Fosroc prohibits thinning its solvent-free systems. Always order Nitoflor Sol on the same purchase order as the flooring resin and primer so housekeeping is never the bottleneck on day one of the pour.

Industry use cases
Warehousing & Logistics
On large warehouse floor coating projects with Nitoflor FC150 or EU5, crews reuse the same spiked rollers and squeegees across hundreds of square metres daily – Nitoflor Sol keeps that kit serviceable between bays and shifts.
Pharmaceutical & Food Processing
Hygienic epoxy/PU coatings demand spotless, residue-free application; Nitoflor Sol cleans tools so no cured resin debris or solvent film contaminates the next coat in GMP-critical areas.
Automotive & Heavy Engineering Workshops
Workshop floors coated with chemical-resistant Nitoflor systems involve repeated batch mixing – paddle mixers and vessels are flushed with Nitoflor Sol between batches to prevent resin build-up.
Car Parks & Commercial Decks
Multi-level deck coatings applied over several days rely on the same application equipment each day; Nitoflor Sol is the housekeeping product that makes daily tool reuse practical and economical.
General Industrial Fit-out
Any factory or plant floor receiving a solvented Nitoflor coating includes Nitoflor Sol in the BOQ as the approved cleaner, keeping the install within Fosroc’s warranted method statement.

How we position Fosroc Nitoflor Sol
Nitoflor Sol should be understood as a system-support product rather than a flooring product in its own right – it earns its place in the bill of quantities because it protects the performance and economics of the Fosroc flooring systems it accompanies, such as Nitoflor EU5, Nitoflor FC150 / FC150 HP, Nitoflor FC140 and Nitoflor Hardtop S, alongside the Nitoprime 25 primer used with them. There is no genuine substitute that keeps you inside Fosroc’s warranted method statement, but in the wider Indian market applicators sometimes reach for generic epoxy cleaning solvents and thinners from suppliers such as Sika (e.g. Sika Colma cleaner-type solvents used with Sikafloor systems), or general-purpose industrial thinners. These may cut wet resin, but they are not matched to the Nitoflor binders, can leave adhesion-affecting residues, and fall outside the system guarantee. Indian-origin players better known for waterproofing and repair – Dr. Fixit (Pidilite), STP Limited and MBCC/MBS-lineage products – largely compete on the flooring and waterproofing resins themselves rather than on a like-for-like branded cleaning solvent. For that reason, when a project is specified on Fosroc Nitoflor, the honest recommendation is to pair it with genuine Nitoflor Sol; switching only the cleaning solvent to save a few rupees per litre is a false economy that risks the very floor finish it is meant to protect. Space Arc Engineering supplies Nitoflor Sol as part of a complete, method-compliant Fosroc flooring package across Delhi NCR and Pan-India.
