    • For use outdoors
    • Adhesive for insulation boards on mineral and bituminous substrates
    • Adhesive for bonding insulation boards to one another


    • Solvent-free
    • High adhesive strength
    • Resistant to bodies of water aggressive to concrete (DIN 4030 XA3)
    • Preparation
      • Substrate requirements

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

        Waterproofing layers must be completely dry.

        Prime absorbent mineral substrates with Kiesol MB.

    • Preparation
      • Combination container

        Break up the powder component before adding to the bitumen emulsion.

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

        Briefly stir the bitumen base material.

        Add the entire quantity of broken-up powder component to the bitumen emulsion.

        Mix for approx. 30 seconds, stop mixing and allow the air introduced during mixing to escape.

        Remove the powder adhering to the side.

        Resume mixing and continue for at least 2 minutes.

        Leave the anchor stirrer near the base throughout the mixing time.

        See mixing instructions.

      • Application requirements

        Temperature of the material, air and substrate: from min. +5 °C to max. +30 °C

      • Ground moisture/non-pressing water (W1-E)

        Apply 6-8 dots of adhesive to the insulation boards and bond to the building element.

        For the water impact class "ground moisture/non-pressing water", we also recommend bonding the insulation boards over their entire surface.


        Pressing water (W2-E)

        Using the material, bond the entire surface area of the insulation boards, including the edges, to the building element in accordance with the official specifications.

    • Application instructions
      • In the case of liquid-applied waterproofing materials, direct sunlight and/or wind exposure can cause accelerated skin formation and accompanying blistering.

        Insulation boards must be firmly fixed at the base point (e.g. projecting foundation) and laid in a bond without joints.

        Until the foundation pit has been filled in, secure the insulation boards so that they cannot slip or slide.

        Protect freshly bonded panels from rear moisture penetration.

    • Working tools / cleaning
      • Anchor stirrer, ladle, notched trowel, smoothing trowel

      • Clean tools with water immediately after use.

        Remove dried-on material using V 101 Thinner (0978).
