    Field of application

    • Priming and levelling


    • Can be subjected to mechanical loads
    • Excellent adhesion on concrete and cement screed
    • Tested against rear moisture penetration
    • Suitable for substrates containing residual moisture
    • Physiologically harmless once fully cured
    • Preparation
      • Substrate requirements

        The substrate must be firm, dimensionally stable, capable of bearing loads and free of loose constituents, dust, oil, grease, rubber marks and other substances that could interfere with adhesion.

        The tensile strength of the surface of the substrate must be at least 1.5 N/mm² on average (smallest individual value of at least 1.0 N/mm²), and the compressive strength must be at least 25 N/mm².

        The substrate can be slightly moist but without liquid film on the surface and should not be exposed to major temperature swings (vapour pressure). In this case the primer must always be applied twice.

        The substrate must be protected from exposure to moisture from underneath during utilisation.

        Concretemax. 6 m% moisture

        Cement screedmax. 6 m% moisture

      • Preparations

        Prepare the substrate by suitable means, e.g. steel ball jetting or diamond grinding, so that it meets the requirements specified above.

        Broken-out or missing areas in the substrate should be filled flush with the surface using Remmers RM systems (RM = Repair Mortar) or Remmers EP mortars.

    • Preparation
      • Mixing time 3 min
      • Combination container

        Add the entire quantity of the hardener (component B) to the base compound (component A).

        Mix thoroughly with a slow-speed electric mixer
        (approx. 300 - 400 rpm).

        Pour the mixture into a separate container and mix again thoroughly.

        Mix for at least 3 minutes.

        Insufficient mixing is indicated by streaks forming.

    • Application
      • Application temperature: min. 10 °C max. 30 °C
      • Pot life 20 min
      • Application requirements

        Temperature of the material, air and substrate: min. +10 °C to max. +30 °C

      • As a general principle, higher temperatures will reduce and lower temperatures will increase the times stated.

    • Storage / shelf life
      • Shelf-life 24 months
      • If stored unopened in its original container in a cool, dry place and protected against frost, the product will keep for at least 24 months.

    • Usage
      • See application examples

    • Application examples
      • Priming

        Apply the mixed resin generously to the surface. Distribute with a suitable tool, e.g. rubber blade, and work into the substrate with an epoxy roller so that pores in the surface of the substrate are completely filled.

        It may be necessary to apply several layers.

        approx. 0.3 - 0.5 kg/m²

      • Levelling layer/scratch coat

        The filled material (up to 1 : 1 parts by weight) is applied to the primed surface and distributed with a suitable trowel. If necessary, roll over with a spiked roller.

        Per mm layer thickness: approx. 0.85 kg/m² binder
        and 0.85 kg/m² Selectmix 01/03

    • General information
      • Unless otherwise specified, all of the values and application rates given above have been determined under laboratory conditions (20 °C) using standard colours. Slight deviations from these values may arise if the product is worked with on site.

        Primers must always be applied so that all pores are filled; it may therefore be necessary to increase the application rate or to apply a second coat.

        Epoxy resins are generally not colourfast when exposed to UV light or weather.

        Abrasive mechanical loads leave traces of wear.

        Refer to the applicable test certificate for the Remmers Deck OS 10 EP pro system.

        Further notes on working, system construction and maintenance of the listed products can be found in the latest Technical Data Sheets and the Remmers system recommendations.

    • Disposal instructions
      • Larger quantities of leftover product should be disposed of in the original containers in accordance with the applicable regulations. Completely empty, clean containers should be recycled. Do not dispose of together with household waste. Do not allow to enter the sewage system. Do not empty into drains.
