Intelligent airtight vapour control membrane (AVCM) with fibre reinforced polymer emulsion. Brush-applied vapour control.
A full BBA-certified polymer-based paste which is applied with a paintbrush and dries to an airtight vapour control membrane (AVCM) with good adhesion on different substrates.
BBA Certified, brush-applied Vapour Control Membrane for Connections and Service Penetrations. Use on multiple surfaces.
For small projects, such as private houses, the Passive Purple Home Pack 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.
