    Why Choose Passive Purple External Brush – Facade Membrane?

    • Vapour open and watertight solution
    • Easy application, all you need is a paintbrush!
    • Fire-rated Class B
    • VOC-free and no nasty chemicals included
    • Fully flexible solution, so no bending or cracking

  • Uses

    For small projects, such as private houses, Passive Purple Brush, facade membrane can be used with a flat paintbrush. In this case, an airless spray device is not needed. If you don’t have an airless sprayer but would still wish to install Passive Purple yourself, don’t worry, we have a roller version for you. It may take a bit longer, but it gets the job done.

    • Wall/Ceiling Connections

    Wall/ceiling connections need to be made airtight, especially when the connections are made of two different types of construction materials such as red brick/concrete or steel/concrete. Different construction materials react differently to changes in humidity and temperature, moving at different rates, which can lead to small cracks in plaster or another type of finishing. That movement can create air leaks that cause your building’s energy performance to suffer and potentially open the gateway for damp and mould to appear.

    • Envelope Penetrations

    Service penetrations can be the downfall of any air tightness testing.  Passive Purple Brush facade membrane is applied around objects that penetrate any surface to the external envelope, sealing where most tapes and membranes fail. Before you apply Passive Purple Brush, first apply polyurethane foam around any penetrations. After hardening, remove the excess foam and apply a generous amount of Passive Purple with a flat paintbrush. In all cases, apply a sufficient, well-covering layer to guarantee airtightness.

    • Window/Door Reveals

    Passive Purple Brush can be applied (and is tested) on different construction materials such as concrete, brick, wood, PVC, aluminium and polyurethane foam. With a coat of Passive Purple External Brush, the whole window/door reveal can be made airtight.
