Why Choose Passive Purple Brush

WINDOW/DOOR REVEALS

This is a common culprit for huge 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 usually used.

CONNECTIONS/JOINTS

Bridge the larger gaps in the wall connections/joints for a tough yet flexible seal which allows itself to work with building settlement before spraying over with Passive Purple Spray

WALL/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/walls with a perimeter application of Passive Purple Brush or Spray

SERVICE PENETRATIONS

service penetrations can be the down fall of any building. Passive Purple and Passive Purple Brush is 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. Passive Purple Brush can be applied with great speed and on damp surfaces, all of which tapes don’t do well on

Why use us? The Brush info

Passive Purple Liquid Brush, this 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, certainly 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, temperature and move at different rates which can lead to small cracks in plaster or another type of finishing, and so creating air leaks that will cause the energy performance of your building to suffer and potentially opening the gateway for damp and mould to appear.
For these wall/ceiling connections, both products can be used: Passive Purple which is sprayed with an airless paint spray device. or Passive Purple brush which is applied by brush, If you don’t have an airless sprayer but would still wish to install Passive Purple your self don’t worry we have a roller version for you, it may take a bit longer but it still gets the job done.

2. Envelope penetrations
service penetrations can be the down fall of any airtightness testing. Passive Purple and Passive Purple Brush is applied around objects that penetrate any surface to the external envelope sealing where most tapes and membranes fail.
Before you apply Passive Purple/Passive Purple Brush, first apply polyurethane foam around any penetrations; after hardening, remove the excessive foam, and apply generous amount of Passive Purple Brush with a flat paintbrush; in all cases, apply a sufficient, well covering layer to guarantee airtightness.

3. Window/Door reveals
Passive Purple can be applied (and is tested) on different construction materials such as concrete, brick, wood, PVC, aluminium, polyurethane foam and with a coat of Passive Purple, the whole window/door reveal can be made airtight.
Working method: cut off the excess of polyurethane foam, and apply Passive Purple Brush.
