Fosroc Chemical Degreaser
Solvent-based industrial degreaser for stripping oil, grease and resinous contamination off concrete, metal and timber before floor coatings go down.
What is it?
A ready-to-use, solvent-based chemical degreaser from Fosroc that penetrates and lifts oil, grease and many resinous contaminants from concrete, metal and timber surfaces.
Where is it used?
Factory and warehouse floors, garages, workshops, machine bases, plant rooms, and as a surface-prep step before Nitoflor floor coatings, screeds and toppings are applied; also for cleaning moulds and formwork.
Why use it?
Contamination left on a floor is the single most common cause of coating delamination. The degreaser strips the oil film so the subsequent epoxy or PU system actually bonds, without needing specialised equipment.
How is it applied?
Brush or mop the degreaser onto the contaminated area, allow it to penetrate and lift the soiling, then agitate and rinse/remove the dissolved residue before the surface is dried and coated.
About Fosroc Chemical Degreaser
Fosroc Chemical Degreaser is a single-component, solvent-based industrial cleaning product designed for the easy removal of oil, grease and many other types of contamination from floors and machinery in factories, garages, workshops, warehouses and similar industrial facilities. Within the Fosroc range it sits as a surface-preparation product rather than a finished floor system: its main job is to get a concrete (or metal, or timber) substrate genuinely clean so that a high-performance coating can be laid over it with confidence. The product is formulated to a tropical grade, which makes it well suited to the high ambient temperatures of Indian sites across Delhi NCR, Gujarat, Maharashtra and the southern states. In a typical Indian industrial-flooring sequence, the floor is first degreased with this product, then mechanically prepared and primed, before a Nitoflor epoxy or polyurethane screed, self-levelling topping or coating is applied. Fosroc specifically lists pre-treatment of contaminated floors prior to Nitoflor coatings, screeds and toppings, and the cleaning of moulds and formwork before shutter-paint and release-agent application, as the two principal uses. Because it relies on a penetrating solvent action rather than mechanical abrasion alone, it reaches into the surface pores of old, oil-soaked concrete where heavy machinery, vehicles or hydraulic equipment have leaked over years of service. Space Arc Engineering supplies Fosroc Chemical Degreaser as an authorised Fosroc distributor, alongside the full Nitoflor flooring range, so a contractor can source the prep chemistry and the finish coat from a single technically-backed supply chain. Buyers should always confirm pack size, exact coverage and the current safety data against the region-specific Technical Data Sheet, since Fosroc gates these figures by country.
The technical insight
The performance logic of Fosroc Chemical Degreaser is bond-failure prevention, not cosmetics. Mineral oils, greases and form-release agents leave a hydrophobic film on concrete that epoxy and PU resins cannot wet out or chemically key into. A solvent-based degreaser works by dissolving that film into a liquid phase so it can be physically lifted and removed, rather than merely smearing it across a wider area as a water-only wash would. The product is described as safe for use on concrete, wood and metal, which is important on sites where the same contamination crosses a concrete floor, a steel plinth and timber formwork. The critical technical caveat is that because it is solvent-based, it is flammable and gives off vapour, so it must be used with adequate ventilation, away from ignition sources, and operatives must wear appropriate PPE. Equally important for the coating contractor: the dissolved oil and the solvent itself must be fully removed and the surface allowed to dry before priming. Any solvent or oil residue trapped at the interface will compromise the very bond the degreasing step was meant to protect. For deeply ingrained or aged contamination, degreasing alone is rarely sufficient; it is normally followed by mechanical preparation such as grinding, captive-blast or scabbling, and on some substrates an additional check (for example a water-break test) is used to confirm the surface is genuinely clean before the Nitoflor system is applied.
Where it is used
- Pre-treatment of oil- and grease-contaminated concrete floors before Nitoflor epoxy or PU coatings, screeds and toppings
- Degreasing of factory, warehouse and workshop floors as part of routine maintenance
- Cleaning of machine bases, plinths and plant equipment soiled with oil or grease
- Cleaning of moulds and formwork before application of shutter paint and release agent
- Removal of resinous and oily contamination from metal surfaces prior to further treatment
- Spot-cleaning of localised oil leaks and spills in garages and service bays
Key advantages
- Penetrating solvent action that rapidly lifts oil, grease and many resinous contaminants from porous substrates
- Effective on concrete, wood and metal, so one product covers mixed substrates on a single job
- Tropical-grade formulation suited to high Indian ambient temperatures
- Requires no specialised application equipment – brush or mop application
- Prepares the surface so subsequent Nitoflor coatings and screeds bond reliably
- Supplied ready to use as part of a complete, single-source Fosroc flooring system from Space Arc
Limitations & considerations
- Solvent-based and flammable – must be used with ventilation, away from ignition sources, with appropriate PPE
- A surface-prep aid, not a stand-alone finished floor system – it must be followed by a coating or topping
- Dissolved oil and solvent residue must be fully removed and the surface dried before priming, or bond can still fail
- Deeply ingrained or aged contamination usually needs mechanical preparation (grinding/blasting) in addition to degreasing
- Numeric specs (specific gravity, flash point, coverage, pack size) are region-specific and must be read from the current country TDS
- Not intended for use as a general-purpose, water-based or low-odour eco cleaner – Fosroc Cleaner C suits that role
Selection & best practice
Treat degreasing as the first step of a defined preparation sequence, never the only step. Remove gross oil and debris first, then apply Fosroc Chemical Degreaser by brush or mop to the contaminated area, allow it to penetrate and lift the contamination, agitate, and then remove the dissolved residue completely – do not let it dry back into the surface. Follow with mechanical preparation (grinding, scabbling or captive-shot blasting) where contamination is heavy or aged, then verify the substrate is clean and dry before priming. Always work with adequate ventilation, keep away from naked flames, sparks and hot work, provide fire extinguishers, and equip operatives with solvent-resistant gloves, eye protection and respiratory protection as the Safety Data Sheet requires. On large industrial floors, trial a small representative area first to confirm the degreasing-plus-preparation regime achieves a coatable surface, and only then proceed across the full bay. Always obtain and follow the current region-specific Fosroc Technical Data Sheet and SDS for the exact product supplied.

How we position Fosroc Chemical Degreaser
Fosroc Chemical Degreaser is positioned as a surface-preparation product, not a finished floor – its value is in protecting the bond of the coating that follows. Within Fosroc’s own range it pairs directly with the Nitoflor epoxy and PU flooring systems, and contractors often use it alongside Fosroc Reebol form-release products on the formwork side. Where a flammable solvent is undesirable, Fosroc’s own Cleaner C offers a water-based, biodegradable, light-alkaline alternative for general industrial degreasing. Against competitor lines, comparable surface-prep and degreasing/cleaning chemistry is offered by Sika (Sika cleaners and Sikafloor surface-prep products), MBCC/Master Builders Solutions (Mastertop floor systems with their own preparation regimes), and STP Limited’s industrial range; Dr. Fixit is strong in waterproofing but is less focused on industrial epoxy-floor surface prep. The honest case for choosing the Fosroc route is single-source compatibility: when the degreaser, the primer and the Nitoflor topping all come from one manufacturer’s tested system – supplied and technically supported by Space Arc Engineering – the risk of an incompatible prep step is removed and any warranty conversation is simpler.
