Why Choose Passive Purple Brush
WINDOW AND DOOR REVEALS
Windows and door reveals are a common culprit for allowing significant air leakage. With its fibre reinforced make-up, Passive Purple Brush will completely seal and dry into a tough airtight membrane that will not peel or become unstuck like your classic silicones and tapes
CONNECTIONS AND JOINTS
Bridge the larger gaps in the wall connections and joints for a tough yet flexible seal which allows itself to work with building settlement before spraying over with Passive Purple Spray
WALL AND CEILING
Completely seal the wall to ceiling connections with a perimeter application of Passive Purple Brush or Spray
SLAB CONNECTIONS
Completely seal the slabs to panels and walls with a perimeter application of Passive Purple Brush or Spray
SERVICE PENETRATIONS
Service penetrations can be the downfall of any building. Passive Purple and Passive Purple Brush are applied around objects that penetrate any surface of the external envelope sealing where most tapes and membranes fail and are too awkward to apply
COST EFFECTIVE
Don’t risk tapes and membranes peeling away or becoming unstuck, leaving your house open for air leakage, costing you labour, energy and stress. Unlike traditional tapes, Passive Purple Brush can be applied with great speed and on damp surfaces

Why use us? The Brush info
Passive Purple Liquid Brush is a much thicker (paintbrush applied version of Passive Purple).
For small projects, such as private houses, Passive Purple Brush can be used with a flat paintbrush. In this case, an airless spray device is not needed.
The wall/ceiling connections also 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.
Both products can be used for these wall/ceiling connections: Passive Purple can be applied with an airless paint spray device. Or Passive Purple Brush can be applied by brush. 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.
Envelope Penetrations
Service penetrations can be the downfall of any air tightness testing. Passive Purple and Passive Purple Brush are applied around objects that penetrate any surface to the external envelope, sealing where most tapes and membranes fail.
Before you apply Passive Purple or Passive Purple Brush, first apply polyurethane foam around any penetrations. After hardening, remove the excess foam and apply a generous amount of Passive Purple Brush with a flat paintbrush. In all cases, apply a sufficient, well-covering layer to guarantee airtightness.
Window/Door Reveals
Passive Purple 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, the whole window/door reveal can be made airtight.
Working method: cut off the excess polyurethane foam, and apply Passive Purple Brush.
