    Field of application

    • For use on floors/walls indoors
    • Waterproofing of new and old buildings with ground contact
    • Waterproofing in load cases 4, 5 and 6 according to DIN 18195 (withdrawn as of July 2017)
    • Water effect classes W1.1-E, W1.2-E, W2.1-E, W3-E and W4-E according to DIN 18533
    • Retrofit waterproofing of buildings according to WTA Code of Practice 4-6
    • Waterproofing of plinths and base points


    • Water-based
    • Solvent-free
    • Water pressure tight
    • Highly flexible, elastic and crack-bridging
    • Radon-tight (verified through testing)
    • Preparation
      • Substrate requirements

        Even-surfaced, mineral substrate.

        Clean, dust-free and capable of supporting a load.

        Matt damp surfaces are permitted.

        If necessary, provide damp proofing.

      • Preparations

        Remove projecting seams and mortar remains.

        Break off or slope corners and edges.

        Smooth out coves using a suitable mineral mortar.

        Close indentations > 5 mm using a suitable mineral material.

        Prime mineral substrates with Kiesol (1:1 in water) or Protective Coating (1:10 in water).

        If the substrate requires reinforcement (restoration), prime using Kiesol (1:1 with water).

        A scratch coat should be applied to weakly absorbent substrates using the product in order to prevent blisters.

    • Application
      • Airless/airmix spraying / trowel application
      • Application temperature: min. 5 °C max. 35 °C
      • Application requirements

        Temperature of the material, air and substrate: from min. +5 °C to max. +35 °C

      • Ready to use, straight from the container.

        Remove any dried material adhering to the edge of the bucket.

        Apply the material in two layers on the previously prepared substrate.

        If a reinforcement fabric is required, embed into the first waterproofing layer.

    • Application instructions
      • Do not apply any further sealing layers until the previous layer has hardened sufficiently.

        Protect freshly coated surfaces from rain, direct sunlight, frost and condensation.

        Protect dry sealant from mechanical damage and UV radiation.

        Please contact Remmers Technical Service (phone +49 5432 83-153) before applying with machine processing.

    • Working tools / cleaning
      • Airless/airmix spraying / trowel application
      • Scoop (4103), smoothing trowel (4004), float (4000), suitable spraying equipment
