    • High area output, very high-yielding
    • Fast drying times
    • Exceptional price/performance ratio
    • 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

        If necessary, a contact layer of MB PUReactive TX can be applied to absorbent substrates at an application rate of approx. 500 g/m².

        Fill depressions > 3 mm using a suitable filler.

    • 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. 60 seconds.

        Remove the powder adhering to the side.

        Mix again for approx. 2 minutes.

    • Application
      • Application temperature: min. 5 °C max. 40 °C
      • Follow-up work and coverings

        Surface waterproofing + Detail waterproofing

        Apply MB PUReactive TX to the prepared substrate using a suitable tool. Embed non-woven fabric of the MB PUReactive F-series correctly so that it is free of air pockets, and cover with the product (overall application rate min. 3.0 kg/m²).

        Embed MB PUReactive F-series fleece overlapping at least 5 cm.

         

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

        The adhesion to the substrate must be tested on a case-by-case basis.

        The maximum wet layer thickness should not exceed 3 mm.

        Protect fresh waterproofing from rain, frost and condensation.

        Direct sunlight and/or wind can cause accelerated skin formation on liquid-applied waterproofing materials.

        The minimum dry layer thickness is 2.1 mm.

        Please contact Remmers Technical Service (phone +49 5432 83900) before applying with machine processing.

    • Working tools / cleaning
      • Mixing tool, flat brush, roller, smoothing trowel
