For floors, walls, and steel surfaces in commercial and industrial settings, a finish that withstands relentless traffic, aggressive chemicals, and constant cleaning is non-negotiable. Megapoxy MC delivers a durable, decorative, hygienic, and dust-free surface. It is engineered for demanding applications, including areas exposed to foodstuffs and hydrogen sulphide environments. This 100% solids, high-build epoxy coating ensures long-term performance where lesser materials fail prematurely.
Megapoxy MC is a heavy-duty, two-component, 100% solids maintenance coating formulated to protect critical infrastructure. It provides exceptional resistance to chemical attack and heavy abrasion, making it ideal for high-traffic and corrosive environments. Its VOC-free composition allows for safe use in areas in contact with foodstuffs. Its specific resistance to hydrogen sulphide protects against degradation in sewage treatment facilities.
Megapoxy MC offers superior performance anchored by its physical properties. A Shore D hardness of 80 indicates significant resistance to heavy abrasion, crucial for areas with forklift traffic or consistent mechanical wear. With a tensile bond strength of 13 Mpa to steel and >3 Mpa to concrete, it forms an unbreakable layer, preventing delamination in high-stress applications. Its 100% solids, Nil VOC formulation means no shrinkage during cure. The applied thickness of 0.4-0.5 mm in a three-coat system translates directly to robust protection without harmful emissions.
Megapoxy MC comes in pre-metered kits for straightforward mixing. For the standard cure, combine Part A and Part B thoroughly for a minimum of 3 minutes with a mechanical stirrer. Ensure all material from the base and corners is incorporated. The mixed product offers a generous two-hour work time at 25°C, allowing ample time for application by brush, roller, squeegee, or airless spray. Recoat times are typically eight hours. If more than 24 hours elapse, the surface requires abrasion with 60-grit paper to ensure optimal intercoat adhesion.
For particularly porous concrete, priming with Megapoxy LVS Sealer is recommended. Megapoxy Thinners can be used to thin the first coat by up to 10% for easier workability. To achieve non-slip surfaces, fine aggregates can be broadcast over the wet first coat or mixed directly into the product. Tools clean up easily with Megapoxy Thinners.
Megapoxy MC excels in a range of demanding environments requiring resilient surface protection:
Megapoxy MC frequently serves as a crucial mid-layer in multi-coat protective systems. For instance, in Plant, Sprinkler, Lift Motor, and Hydrant Pump Rooms, it is typically applied as the second step. This often occurs over a repair mortar like Megapoxy H Epoxy Resin, providing the main protective and trafficable layer before a final sealant such as Adheseal S100 is applied. This layering approach ensures a robust, seamless, and long-wearing finish that withstands the heavy demands of these utility spaces.
Megapoxy MC stands out as a heavy-duty, 100% solids, high-build epoxy coating engineered for severe abrasion and chemical resistance across floors, walls, and steel. For applications requiring a different formulation within the Megapoxy family, Megapoxy CT5 Epoxy offers an alternative solution. For particularly porous surfaces that require priming before applying Megapoxy MC, consider Megapoxy LVS Sealer.
Yes, Megapoxy MC is suitable for structures in contact with foodstuffs. It is a 100% solids system and contains Nil VOCs, making it appropriate for hygienic environments like food and beverage facilities, including abattoirs.
Concrete surfaces require thorough mechanical abrasion like scabbling, grit blasting, or grinding to remove laitance and ensure maximum adhesion. Acid etching is an alternative if mechanical methods are not possible. The surface must be clean, free from grease and oil, and surface dry.
Yes, Megapoxy MC is formulated to be resistant to hydrogen sulphide. This makes it a suitable protective coating for concrete and steel structures in sewage treatment plants and pipes where H2S may be present.
Incorrect mixing or an inaccurate ratio of Part A and Part B will compromise the cured system. This can lead to lower physical properties, unsatisfactory curing, and potential discolouration over time. Always mix according to the specified ratios and times.
To create a non-slip surface, broadcast epoxy quality sand, glass beads, carborundum, or silicone oxide onto the freshly applied first coat. You can then leave it or recoat with Megapoxy MC to encapsulate the aggregate. Fine aggregates can also be mixed directly into the product before application.

Preparation is critical for performance. All substrates must be structurally sound, clean, dry, and free of all contaminants.
Mechanically grind or blast to remove all laitance and contaminants. Degrease as required. Ensure moisture content is within acceptable limits.
Grit blast to AS CK 9.4-1964 Class 3 finish. Degrease immediately after abrasion. Do not allow to flash rust.
For porous concrete, applying a primer seals the surface to prevent pinholes and blistering from substrate outgassing.
Apply one coat of Megapoxy LVS - Low Viscosity Sealer using a roller, brush, or spray.
Apply at a rate of 8-10m² per litre. Thinning is not recommended.
Precise mixing is essential for the coating to cure correctly and achieve its full strength. Do not guess the time.
Add Part B to Part A. Mix for 3 mins with a low-speed drill (200rpm max). Scrape all sides and base, then mix for 2 more mins. Total 5 mins.
Add Part B to Part A. Mix for 2 mins (200rpm max). Scrape sides and base, then mix for 1 more min. Total 3 mins.
Apply the mixed Megapoxy MC evenly to the prepared (and primed, if applicable) surface. For aggressive environments, a three-coat application is recommended.
Apply using a brush, roller, or airless spray. (Note: Squeegee is for MC2 only).
If required, the first coat can be thinned up to 10% with Megapoxy Thinners. Reduce to 5% for the second coat. Ensure all thinners have evaporated before recoating.
Both Megapoxy MC Part A (Warning) and Part B (Danger) are classified as hazardous chemicals and Dangerous Goods (S5 - Caution). Refer to the Safety Data Sheet (SDS) for full details. Effects may be delayed.
Wear safety shoes, gloves (nitrile rubber recommended), and safety glasses. If an inhalation risk exists, particularly with Part B, wear an appropriate respirator suitable for organic vapour/particulates.
For Part A, natural ventilation may be adequate under normal use. For Part B, ensure ventilation is sufficient to maintain air concentrations below exposure standards; use local exhaust ventilation or an appropriate respirator. Do not enter confined spaces where vapours may have collected.
Store in a cool, dry, well-ventilated place, out of direct sunlight, and away from foodstuffs, oxidising agents, and ignition sources. Keep containers upright and closed. Part B must be stored locked up. Dispose of material and containers in accordance with local, regional, national, and international regulations. If possible, recycle material and its container.
Proper surface preparation is critical for the long-term adhesion and performance of Megapoxy MC. Adhere to these guidelines to prevent coating failure.
Surface prep: Concrete must be free from grease, oil, and surface laitance. Mechanically abrade the surface using scabbling, grit blasting, or grinding. If mechanical abrasion is not feasible, acid etching with a 1:1 hydrochloric acid to water solution applied at 0.5 L/m² for 10 minutes is acceptable. Thoroughly wash and scrub the treated area to remove loose sand. Allow 24 hours to dry; the concrete must be surface dry for optimal adhesion. Remove existing paint by flame-cleaning, scutching, diamond grinding, or scabbling.
Primer: Optional. For particularly porous concrete surfaces, prime with Megapoxy LVS - Low Viscosity Sealer at a rate of 8-10 m²/L. Do not thin Megapoxy LVS. Recoat 8-24 hours after LVS application.
Surface prep: Grit blast to an AS CK 9.4 - 1964 Class 3 finish. If grit blasting is not possible, mechanically abrade the surface to a clean, bright metal finish. Degrease the surface thoroughly with an industrial-grade degreaser after abrasion. Wire brushing is not sufficient and will yield minimal adhesion. All existing paint and galvanising must be removed using quality paint stripper, followed by grit blasting or grinding.
Primer: Not required for prepared steel.
