Intelligent Membranes have the next generation of Liquid applied products.

Passive Purple, the world's first Passivhaus Certified Airtight Liquid Vapour control that can be brush, sprayed or roll applied

Here at Intelligent Membranes, we offer liquid membranes for five star protection of windows and surfaces using biodegradable natural latex. Our liquid waterproofing membranes prevent the passage of water and other liquids through a building membrane. Intelligent Membrane’s coatings are used to protect a range of materials, not only in building construction, but also heritage buildings using sustainable and VOC-free building membranes.

Our Passive Purple liquid membranes are BBA and Passivhaus certified: the Passivhaus Trust (PHT) is an independent industry-leading organisation that promotes the reduction of a building’s ecological footprint.

Passive Purple External - Breathable weatherproof facade membrane that is Class B FIRE.

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 mould 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.

Waterproof Blue - Wet room waterproofing

Ideal for the waterproofing of concrete, bricks and cement based surfaces in showers, bathrooms, steam areas and wet rooms that need waterproofing prior to tiling.

Application

STEP 1 – Fill the joints between the surface, and the draining and tubes with a paintable waterproof sealant. When these joints are < 5mm, enlarge these
before applying the sealant.
STEP 2 – Apply the Waterproof Blue, waterproof paint membrane with a longhaired roller, paintbrush or airless paint spray machine in two coats. Coverage in 2 layers is minimal 800gr/m2, or 2 layers of approx. 400 gr/m2 depending on the roughness of the substrate. Second layer to be applied crosswise on the first layer, when the first layer has dried out. Make sure to check for complete coverage.
STEP 3 –When the second layer of Waterproof Blue, water proof paint membrane has dried out (24 to 48 hours after application), apply tiling as finishing. Suitable tiling glues include: cement glue class C2 or dispersion glue class D2TE, according EN12004
