**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.
With its fibre reinforced polymer technology, Passive Purple Brush can bridge gaps of up to 5mm. Ideally, you want the structure to have as little gaps in as possible to save time and cost on materials. once all connections, joints, boards and penetrations are complete and located, simply use a firm paint brush to fill and seal over the gaps and joints. this alone will reduce air leakage an enormous amount leaving your final spray coat ”if required” the icing on the cake. With a filler style technique and putty like consistency, Passive Purple Brush is extremely easy and fast to apply with no surface or area a problem.
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.

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.
