Why use us? The Passive low down!

Now we know what you’re thinking, is it a nasty chemical? Well, No!! passive purple is a VOC FREE water based product. So it’s completely free of any nasty chemicals or fumes…also as a water based product, cleaning your paintbrushes and airless spray device is an easy, no mess task.

Passive Purple adheres to any form of construction allowing you to achieve maximum results for your desired goal. Once dry Passive Purple forms an extremely tough yet flexible polymer membrane allowing it to move with the building settlement, whilst at the same time being super effective against impact damage, also eliminating the inevitable rips, tears, unstuck tapes, staple holes and large number of repairs you would expect to find on the classic paper membranes. Intelligent Membranes have eradicated the need for paper, tapes and staples which eradicates all the problems that come with it i.e. labour time, large quantity of damage repairs and waste material, effectively saving you money aswell as achieving your goal without the worry of failure.

Envelope Areas 

Passive Purple Liquid Airtight Vapour Control Membrane is an airtight coating which is spray applied with an airless spray device on all areas of an external envelope (warm side of the insulation) of a building including them difficult connection floor, wall, roof and joist areas. As long as Passive Purple is used on the warm side of the insulation Passive Purple can be applied to either face of the external envelope.
The material to have Passive purple applied on must be dust free, solid and closed before starting the application. A closed surface implies that holes and joints need to be closed beforehand: large holes and joints (> 5mm) can be closed with a fast setting cement based products or polyurethane foam, small holes and joints (2-5mm) can be closed with Passive Purple Liquid Brush, this is a much thicker (paintbrush applied version of Passive Purple)
After these preparations, Passive Purple can be sprayed with an airless paint spray device; this fast application method allows a single operative to apply up to 300 m2 per day.
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.
