Description
Floors, walls and steel in mechanical workshops, plant rooms and food and beverage facilities need a hard-wearing coating, and Megapoxy MC is the manufacturer’s heavy duty maintenance coating for them. The TDS describes a two-component, 100% solids, high build, highly chemical resistant coating for commercial and industrial floor, wall and steel protection, with a decorative, hygienic, dust free finish.
The TDS describes it as volatile organic compounds free (Nil V.O.C.) and suitable for coating and protecting structures in contact with foodstuffs. Figures below are for the standard version, not the rapid setting MC2.

Where to Use
The TDS lists these recommended applications:
- Food and beverage facilities, including abattoirs
- Factory and warehouse floors
- Mechanical workshops and plant rooms
- Car parks and ramps, including forklift areas
- Chemical storage tanks and bunds
- Protective coatings for concrete and steel, and sewage treatment plants
How to Apply
- Prepare the surface: concrete must be free of grease and oil, with laitance removed by scabbling, grit blasting or grinding, and surface dry for maximum adhesion. Grit blast and degrease metals. Remove existing coatings.
- Prime if needed: the TDS recommends Megapoxy LVS Low Viscosity Sealer on particularly porous surfaces.
- Mix: add all of Part B to the Part A tin and mix for a minimum of 3 minutes, by hand or with a mechanical stirrer at 200 rpm or lower, scraping the base and corners, then scrape the sides and mix 2 minutes more.
- Apply: apply by brush, roller or airless spray. Megapoxy MC can be thinned with Megapoxy Thinners: a maximum of 10% on the first coat and 5% on the second. All thinners must have evaporated before the next coat is applied.
- Re-coat: re-coat after 8 hours at 25 degrees C. If more than 24 hours elapses, abrade the surface to a uniform dull finish with 60 grit paper first.
Important Notes
- Inaccurate ratios or poor mixing lower the physical properties of the cured system and may leave it uncured or discoloured on ageing.
- Wear disposable rubber gloves and refer to the Safety Data Sheet for hazard and handling information. Figures are from the TDS, Revision 4, 5 March 2024.
