    Product specifications

    The stated values represent typical product characteristics and are not to be construed as binding product specifications.

    Field of application

    • Primer, bonding layer, levelling layer
    • Producing compression-resistant mortars, flow coatings
    • Base layer for blinded covers


    • Can be subjected to mechanical loads
    • Can be subjected to chemical loads
    • Good penetration characteristics
    • Contains no plasticisers, nonylphenols or alkylphenols
    • Physiologically harmless once fully cured
    • Suitable for use as primer without broadcasting underneath Remmers PU and EU coatings
    • 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.

        Substrates must have reached their moisture balance and must also be protected against moisture penetration from the reverse side, including during use.

        Concretemax. 4 m% moisture

        Cement screedmax. 4 m% moisture

        Anhydrite screedmax. 0.3 m% moisture

        Magnesite screed2-4 m% moisture

        In the case of anhydrite and magnesite screeds, moisture cannot be permitted to penetrate from building elements or the ground.

        As a general principle, systems which permit the diffusion of water vapour are recommended for use with anhydrite and magnesite screeds.

      • 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.

    • Application
      • Application temperature: min. 8 °C max. 30 °C
      • By brush / By roller / Self-levelling coating / Apply standing
      • Pot life 25 min
      • Application requirements

        Temperature of material, environment and substrate: min. +8 °C up to max. +30 °C.

      • 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 blade, rubber slider, epoxy roller, spiked roller, mixing device, possibly compulsory 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 12 months
      • If stored unopened in its original container in a cool, dry place and protected against frost, the product will keep for at least 12 months.

    • Usage
      • See application examples

    • Application examples
      • Impregnation/strengthening

        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 binder (depending on substrate)

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

      • 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

      • Synthetic resin mortar

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

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

      • Base layer for blinded coatings

        Pour the material, filled with a ratio of up to 1 : 1.5 parts per weight on the previously prepared surface, distribute with a suitable trowel and, if needed, 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, excess material after hardening.

        At a layer thickness of 1.5 mm: approx. 1.0 kg/m² binder
        and 1.5 kg/m² Selectmix SBL

    • 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.

        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.

    • 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.
