    • Preparation
      • Substrate requirements

        The substrate must be clean, dry, flat and capable of bearing a load, and free of dust, oil, grease and release agents.

        Roughen non-mineral and pore-free substrates.

        Absorbent mineral substrates, not self-compacting concrete (SCC), may be slightly damp.

      • Preparations

        Remove projecting seams and mortar remains.

        Break off or chamfer corners and edges.

        Produce the sealing cove with a suitable mortar.

        Use a suitable mortar to seal construction joints in concrete basements.

        Use a suitable mineral mortar or MB TX 2K mixed with suitable quartz sand (1:1 to 1:3 by mass) to close up cavities of more than 5 mm.

        Large-pored substrates can be sealed beforehand with a scratch coat of MB TX 2K mixed with sand (Remmers Quartz Sand F 36).

        Roughen the surface of plastic pipes with sandpaper; clean and, if necessary, sand metal pipes.

        If necessary, provide damp proofing.

        Prime absorbent mineral substrates with Kiesol MB.

        Apply a scratch coat of the product as a contact layer and to prevent bubbles (approx. 500 g MB 2K TX/m²).

    • Preparation
      • Mixing ratio comp. A 1 : comp. B 1
      • Mixing time 3 min
      • Combination container

        Stir the liquid component with a suitable mixing tool.

        Loosen the powder component and add it in full to the liquid component.

        Mix for approx. 1 minute before suspending the mixing process to allow the air that has been stirred in to escape.

        Remove the powder adhering to the side.

        Mix again for approx. 2 minutes.

        Keep the mixing tool near the bottom of the bucket while mixing.

    • Application
      • Application by filling knife / Trowel application
      • Surface waterproofing

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

        Pipes passing through walls

        W1-E: seal pipe penetrations by using the product to form a cove around them.

        W2.1-E: use an adhesive flange or a suitable loose/fixed flange to integrate pipe penetrations into the waterproofing material.

        Connection details/building element joints

        Corners and connection joints should be bridged with Tape VF.

        Apply the product, embed Tape VF over the entire surface, ensuring that there are no bubbles or creases.

        Use Tape VF to connect to rising building elements (e.g. basement shafts).

        Subsequent coatings

        After 4 hours, work can be continued with adhesive mortar, filling
        mortar or reinforcement mortar.

    • Application instructions
      • During application, the surface temperature of the substrate must be > 3 kelvin above the dew point temperature of the surrounding air.

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

        Do not use in direct sunlight.

        Do not use on untreated aluminium.

        The scratch layer does not as a rule count as a waterproofing layer.

        The maximum total wet film thickness must not exceed 8 mm.

        Moving the material (e.g. by stirring) in the mixing bucket can prevent premature skin formation.

        Mortar that has already set cannot be made workable again by adding
        water or fresh mortar.

        Protect the fresh waterproofing layer from rain, direct sunlight, frost and condensation water.

        Once dry, protect from mechanical damage.

    • Working tools / cleaning
      • Application by filling knife / Trowel application
      • Mixing tool, scoop, layer thickness trowel

        Clean tools with water while the material is still fresh.

        Any material that has already begun to dry can only be removed mechanically.

    • Storage / shelf life
      • Store frost-free and cool / protect for moisture / close containers
      • Shelf-life 9 months
      • If stored unopened in its original container in a cool, dry place and protected against frost, the product will keep for at least 9 months.

    • Usage
      • Approx. 1.05 kg/m²/mm dry layer thickness
        Approx. 4.2 kg/m² at 4 mm dry layer thickness

      • Apply to a large enough trial area to determine the precise amount required.
