    • Preparation
      • Substrate requirements

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

        Matt damp surfaces are permitted.

    • Application
      • Application temperature: min. 5 °C max. 30 °C
      • By brush / By roller / Airless/airmix spraying
      • Ready to use, straight from the container.

        Apply several layers of the material on to the prepared substrate.

        Dilute with water if necessary.

        Add mineral mortar products to the mixing water if necessary.

        When using as a primer under bituminous waterproofing materials (PMBCs), dilute with water in a mixing ratio of 1:10.

        In case of sedimentation of the bitumen solid, stir the material with a suitable mixing tool.

    • Application instructions
      • When using liquid-applied materials, direct sunlight and/or wind can cause accelerated skin formation and associated blistering. This effect is amplified on surfaces with a large number of cavities.

        Do not apply any further 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.

    • Working tools / cleaning
      • By brush / By roller / Airless/airmix spraying
      • Flat brush, slurry brush, suitable spraying equipment

        Clean tools immediately after use with water.

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