White Airtight Vapour Control Paint (5kg) – Brush

Price Not Available In Your Country, Please Contact Us

Airtight White brush vapour control membrane is a much thicker airtight vapour control paint. It is the paintbrush applied version of Passive Purple Edition – Airtight White.

**FREE DELIVERY**

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.

For small projects, such as private houses, Airtight White brush can be used with a flat paintbrush. In this case, an airless spray device is not needed. A spray applied version is available however, if you don’t have an airless sprayer but would still wish to install Airtight White yourself, don’t worry, we have a roller version for you. It may take a bit longer, but it gets the job done.

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. This is where Airtight White comes into play and can be used for wall/ceiling connections.

  • Key Details

    Why Choose Passive Purple Airtight White Vapour Control Membrane?

    • Window And Door Reveals – Windows and door reveals are a common culprit for allowing significant air leakage. With its fibre reinforced make-up, Airtight White Brush will completely seal and dry into a tough airtight vapour control membrane that will not peel or become unstuck like your classic silicones and tapes
    • Connection Joints – Bridge the larger gaps in the wall connections and joints for a tough yet flexible seal which allows itself to work with building settlement before spraying over with Airtight White Spray
    • Walls And Ceilings – Completely seal the wall to ceiling connections with a perimeter application of Airtight White Brush vapour control membrane or airtight membrane Spray
    • Slab Connections – Completely seal the slabs to panels and walls with a perimeter application of Airtight White Brush or Spray
    • Service Penetrations – Service penetrations can be the downfall of any building. Airtight White and Airtight White Brush are 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. Unlike traditional tapes, Airtight White Brush can be applied with great speed and on damp surfaces

    Envelope Penetrations

    Service penetrations can be the downfall of any air tightness or flexible membrane testing. Airtight White and Airtight White Brush vapour control paint are applied around objects that penetrate any surface to the external envelope, sealing where most tapes and membranes fail.

    Before you apply Airtight White or Airtight White Brush, first apply polyurethane foam around any penetrations. After hardening, remove the excess foam and apply a generous amount of Airtight White Brush with a flat paintbrush. In all cases, apply a sufficient, well-covering layer for reliable airtightness and a guaranteed airtight membrane.

    Window/Door Reveals

    Airtight White vapour control membrane can be applied (and is tested) on different construction materials such as concrete, brick, wood, PVC, aluminium and polyurethane foam. With a coat of Airtight White, the whole window/door reveal can be made airtight.

    Working method: cut off the excess polyurethane foam, and apply Airtight White Brush.
