Passive Purple Internal – 11.4kg XL

Passive Purple Liquid Airtight Vapour Control Membrane is an airtight coating that is applied with an airless spray device on all areas of an external envelope (warm side of the insulation) of a building. This includes those difficult connection areas to the floor, wall, roof and joist.When Passive Purple is used on the warm side of the insulation, it can be applied to either face of the external envelope. To install Passive Purple, you simply need to ensure the material or surface is 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 on with an airless machine, allowing you to apply up to 300 m2 per day with a single operator. For small projects, such as private houses, Passive Purple Brush can be used with a flat paintbrush. The wall and 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 and concrete or steel and 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. This can create air leaks that will cause the energy performance of your building to suffer and potentially opening the gateway for damp and mold to appear. Both airtight paints can be used for these wall to ceiling connections: Passive Purple spray-applied and Passive Purple brush. Note: 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 still gets the job done. Passive Purple Internal is a Passive House High-performance building material.

WHY USE US? THE PASSIVE LOW DOWN!
We know what you’re thinking. Is it a nasty chemical? Well, No!! Passive Purple is a VOC-free water-based product. It’s completely free of any nasty chemicals or fumes… What’s more, as a water-based product, cleaning your paintbrushes and airless spray device is a smooth, 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 while also being super effective against impact damage. Passive Purple eliminates the inevitable rips, tears, unstuck tapes, staple holes, and many repairs you would expect to find on the classic paper membranes.

We have eradicated the need for paper, tapes and staples through this product, which eliminates all the problems that came with it (labour time, large quantity of damage repairs and waste material).

Passive Purple saves you money and delivers well above your goals.

Envelope Areas

Passive Purple Liquid Airtight Vapour Control Membrane is an airtight coating that is spray applied with an airless spray device. It is designed to cover all areas of an external envelope (warm side of the insulation) of a building, including difficult connections in floors, walls, roofs 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 surface material where you apply Passive Purple needs to 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 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, 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.
