3. Usage Guide and Application Notes

The quality of surface preparation directly impacts the performance and durability of the epoxy system.

3.1. Surface Preparation

Concrete Surfaces:

  • Must be sound, dimensionally stable, clean, and free from any laitance, paint, oil, grease, form-release agents, or curing compounds.

  • The concrete surface should be chipped to expose the coarse aggregate, ensuring the complete removal of laitance and loose surface material.

  • Fresh concrete should have a minimum compressive strength of 25 MPa; higher strength is preferred.

  • Important Note: The concrete surface must be completely clean and dry at the time of grouting.

  • Concrete areas to be grouted should not be primed or sealed.

Metal Surfaces:

  • Metal surfaces or components to be installed (such as base plates and rails) must be free of rust or flaking.

  • They should be cleaned just before grouting to achieve proper adhesion.

  • Use a primer only if a long delay between cleaning and grouting poses a risk of rust or contamination.

  • Surfaces you do not want the grout to adhere to (like formwork) should be protected with thick layers of wax.

3.2. Application Temperatures

  • ECOFLOW EP950 should not be applied when the temperature of the contact surfaces is below 10 °C.

  • If the ambient temperature is below 0 °C, artificial heating can be used.

  • In hot summer weather, protect the host concrete from direct sunlight.

  • The minimum product application temperature is 5 °C.

3.3. Mixing

  • Do not split packages or alter the ratio of resin components under any circumstances.

  • Mix using a low-speed drill with a mixing paddle.

  • Add the contents of the reactant container (Part B) to the base component (Part A) in a suitable mixing container. Ensure both resin components are fully transferred.

  • Mix for one minute, then slowly add the aggregate (Part C) and continue mixing until a pourable consistency is achieved.

  • Do not over-mix, as this can introduce air into the mixture.

3.4. Application Method

  • Formwork: ECOFLOW EP950 requires formwork, typically made of wood. Forms must be strong enough, braced or shored to withstand the pressure of the grout, and completely watertight. Lining forms with polyethylene ensures easy removal.

  • Pouring and Leveling: Immediately after mixing, pour the grout into the prepared area and use a steel trowel to level the surface.

  • Form Removal: Allow the grout to harden before removing the forms (usually after 6 hours).

  • Curing Time: The curing time of the mortar depends on the temperature of the base and foundation, not the ambient air temperature.

  • Pot Life: 40 to 50 minutes at 25 °C.

  • Full Cure: After 7 days at 25 °C.

3.5. Consumption Rate and Limitations

  • Consumption: Each 2.2 kg of ECOFLOW EP950 provides a layer with a thickness of 1 cm per square meter.

  • Minimum Thickness: A minimum thickness of 10 mm must be maintained to ensure all stated properties are achieved.

  • Limitations:

    • Do not apply at temperatures below 5 °C.

    • Do not dilute ECOFLOW EP950 with solvents; solvents prevent proper curing.

    • Do not apply a thickness of more than 150 mm in a single layer.

3.6. Cleanup and Maintenance

  • Tool Cleanup: Wash all equipment with a solvent or soap/water before the product hardens.

  • Hardened Material: Cured material can only be removed mechanically.

  • Storage:

    • Store at temperatures between 10 to 30 °C, away from direct sunlight, protected from extreme heat, and away from open flames.

    • Store in a dry condition and away from direct rain.

  • Shelf Life: 18 months from the date of manufacture in original, unopened packaging.

4. Technical Specifications and Relevant Standards

ECOFLOW EP950 is evaluated and produced based on reputable international standards:

  • Relevant Standards:

    • ASTM C579 (Standard Test Methods for Compressive Strength of Chemical-Resistant Mortars, Grouts, Monolithic Surfacings, and Polymer Concretes): This standard is used to determine the compressive strength of mortars, grouts, and polymer concretes.

    • ASTM C905 (Standard Test Method for Apparent Density of Preformed Block-Type Thermal Insulation): (Note: The specific standard for epoxy grout density is usually not ASTM C905 for thermal insulation. A more appropriate standard for the density of cementitious grout mixtures is ASTM C138, although the manufacturer may use a similar test method or a different standard.)

    • General Epoxy Resin Standards: Epoxy grouts are typically evaluated based on standards like ASTM C881 (Standard Specification for Epoxy-Resin-Base Bonding Systems for Concrete), which addresses properties such as bond, tensile, and compressive strength.

5. Safety and Health Considerations

ECOFLOW EP950 is formulated for industrial and professional use and must be kept out of reach of children. These products contain chemicals that may be flammable and potentially harmful to health if not stored and used correctly.
