  • 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.

      Concretemax. 6 m% moisture

      Cement screedmax. 6 m% moisture

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

      Weakly absorbing substrates must be tested with regard to their suitability for coating, if necessary a trial surface must be set up.

      If the product is used on green concrete (water–cement ratio < 0,45) the substrate must be suitable for blasting or grinding.

    • 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 PCC systems or Remmers EP mortars.

  • Preparation
    • Mixing ratio comp. A 71 : comp. B 29
    • 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. 5 °C max. 25 °C
    • By brush / By roller / Self-levelling coating / Apply standing
    • Pot life 25 min
    • Application requirements

      Temperature of material, surroundings and substrate: min. +5 °C - max. +25 °C.

    • Setting may be accelerated by adding ACC H. The associated directions for use are available upon request.

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

  • Working tools / cleaning
    • By brush / By roller / Self-levelling coating / Apply standing
    • Smoothing trowel, toothed trowel, toothed squeegee, rubber scraper, epoxy roller, spiked roller, mixing equipment, if necessary a positive mixer

    • More detailed information can be found in the Remmers Tool Programme.

      Clean tools, equipment and splashed material immediately while fresh with V 101 Thinner.

      Take suitable protective and waste disposal measures when cleaning.

  • Storage / shelf life
    • Store frost-free
    • 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
    • Leveling layer / Roughness compensation

      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 thickness of the base layer: approx. 0.85 kg/m² of binder and 0.85 kg/m² of Selectmix 01/03

    • Epoxy mortar

      The filled material (up to 1 : 10 parts by weight) is distributed with a smoothing trowel and smoothed.

      Per mm thickness : approx. 0.2 kg/m² of binder and 2.0 kg/m² of Selectmix 25

    • Impregnation / Solidification

      The mixed resin is diluted with up to 20% by mass of Remmers V 101 Thinner and applied to the surface until saturation, using a suitable tool, e.g. rubber blade, and then worked into the substrate with an epoxy roller.

      It may be necessary to apply several layers.

      Approx. 0.30 - 0.50 kg/m² of binder (depending on the substrate)

    • Primer

      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. 0.30 - 0.50 kg/m² of binder (depending on the substrate)

    • Base layer for blinding layer

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

      Then liberally broadcast fire-dried quartz sand over the base layer while it is still fresh.

      Remove any loose, surplus sand after hardening.

      Per mm thickness of the base layer: approx. 0.85 kg/m² of binder and 0.85 kg/m² of 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). 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.

      As mineral substrates have different absorption capacities, impregnated surfaces have a spotted appearance. Not suitable for high-visibility surfaces.

      When coating continuous surfaces, only use materials with the same batch number as slight differences in colour, gloss and texture may occur.

      Abrasive mechanical loads leave traces of wear.

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

      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.
