- Automotive Workshops and Garages: Resistant to oils, fuels, and chemicals typically found in automotive service environments.
- Food and Beverage Facilities: Suitable for areas requiring hygienic, durable, and seamless floors.
- Chemical Processing Units: Performs well in spaces exposed to mild chemical spills and corrosive agents.
- Pharmaceutical Plants: Ensures a smooth, non-dusting surface, reducing contamination risks.
- Power Plants and Utility Areas: Protects surfaces from mechanical and thermal stresses.
- Public Spaces and Parking Garages: Offers high durability for areas exposed to heavy vehicular traffic and pedestrian footfall.
- Cold Storage Areas: Performs well in environments with temperature fluctuations and low ambient temperatures.
- Educational and Commercial Buildings: Provides durable, easy-to-maintain surfaces in hallways, lobbies, and utility areas.
SURFACE PREPARATION
Surfaces should be free from grease, oil chemical, dust, laitance, loose concrete and should have minimum amounts of moisture. Appropriate surface preparation equipment such as shot blast, scarified or grinder must be used to obtain a sound surface. Substrates which show any traces of oil must be degreased with a chemical degreaser prior to any surface preparation or grit blasting. Cracks, pinholes, potholes should be repaired using Ressi EPO Crack Fill. Uneven concrete should be levelled to produce flat surfaces as much as possible. New concrete floors should be atleast 28 Days old prior to application and must not have moisture exceeding 2% using a standard moisture meter. Expansion, control and isolation joints should be carried through floors filled with suitable joint treatment. The concrete surface needs to be primed using an appropriate epoxy primer from the Ressichem Epoxy primer range.
PRIMING
Prepared surfaces should be primed using Ressi EPO Primer or any other suitable Primer recommended by Ressichem. The primer should be penetrated / coated onto the substrate using a stillbrush or roller and allowed to become tacky (10 – 20 mins before the application of Ressi EPO Mid Coat S – CR. The primer should be allowed to dry. If the primer has dried, additional coat of primer should be applied and allowed to become tacky.
MIXING
Stir the base and hardener component separately first. Add the Filler component into the base / Hardener material and stir it until the complete material is homogenous. A high-speed drill machine with high RPM levels can be used to homogenize both Part A (base / Resin) and Part C (Filler Material). Once Parts A and C are homogenized, part B should be added into the mix and homogenized accordingly. All Materials should be mixed for at least 3 to 7 minutes a low rpm (400 – 600 rpm) Speed until a uniform homogenized mix is achieved.
APPLICATION
Lay Ressi EPO Mid Coat S – CR over the prepared surface whilst the primer is still tacky. Spread out with a notched trowel to a uniform thickness between 2mm to 5mm. The minimum recommended thickness of Ressi EPO Mid Coat S – CR is 2mm. Level the material using appropriate trowels and tools to the desired level. A spiked roller should be used to achieve a uniform surface.
LIMITATION
At higher temperatures pot life will be reduced. For working on Low temperatures below 10°C, Ressi EPO Mid Coat S – CR may be placed over a hot water bath. The service temperature for the application of Ressi EPO Mid Coat S – CR is between 15°C and 35°C.
