    • Application
      • By brush / mortar cover / trowel application
      • Application temperature: min. 5 °C max. 30 °C
      • Application requirements

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

      • Vertical surface waterproofing

        Apply the product in two layers on the previously prepared substrate in accordance with the applicable regulations.

        Horizontal surface waterproofing

        Apply the product in two layers on the previously prepared substrate in accordance with the applicable regulations.

        Apply the second layer once the first can no longer be damaged.

        After the waterproofing has dried thoroughly, place two layers of PE sheet over the waterproofing before the screed is laid.

        At the edges, the waterproofing layer is applied up to the upper edge of the floor or up to the horizontal barrier.

        Connection details/building element joints

        Bridge corner and connection joints with the Tape VF joint tape system.

        Apply MB 2K and work in the Tape VF so that it is crease-free.

         

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

        Mixing by hand and the mixing of partial quantities are not permitted.

        Apply waterproofing material to the side facing the water (positive water load).

        Rigid preliminary waterproofing is required in the case of moisture penetration from the rear.

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

        Protect the dry waterproofing material from mechanical damage.

        Add a further load-distributing layer if using the product for waterproofing under raised floor supports.

         

        Laying ceramic tiles

        Lay tiles once the waterproofing material can sustain foot traffic without being damaged.
