AIRTIGHT WHITE

Why use us? The Passive low down!

Now we know what you’re thinking, is it a nasty chemical? Well, No!! airtight white is a VOC FREE water based product. So it’s completely free of any nasty chemicals or fumes…also as a water based product, cleaning your paintbrushes and airless spray device is an easy, no mess task.

Airtight White adheres to any form of construction allowing you to achieve maximum results for your desired goal. Once dry Airtight White forms an extremely tough yet flexible polymer membrane allowing it to move with the building settlement, whilst at the same time being super effective against impact damage, also eliminating the inevitable rips, tears, unstuck tapes, staple holes and large number of repairs you would expect to find on the classic paper membranes. Intelligent Membranes have eradicated the need for paper, tapes and staples which eradicates all the problems that come with it i.e. labour time, large quantity of damage repairs and waste material, effectively saving you money aswell as achieving your goal without the worry of failure.

Envelope areas 
Airtight White Liquid Airtight Vapour Control Membrane is an airtight coating which is spray applied with an airless spray device on all areas of an external envelope of a building including them difficult connection floor, wall, roof and joist areas. As long as Airtight White is used on the warm side of the insulation Airtight White can be applied to either face of the external envelope.
The material to have Airtight White applied on must 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 a fast setting cement based products or polyurethane foam, small holes and joints (2-5mm) can be closed with Airtight White Liquid Brush, this is a much thicker (paintbrush applied version of Airtight White)
After these preparations, Airtight White 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, Airtight White 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, certainly 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, temperature and move at different rates which can lead to small cracks in plaster or another type of finishing, and so creating air leaks that will cause the energy performance of your building to suffer and potentially opening the gateway for damp and mould to appear.
For these wall/ceiling connections, both products can be used: Airtight White which is sprayed with an airless paint spray device. or Airtight White brush which is applied by brush, If you don’t have an airless sprayer but would still wish to install Airtight White your self don’t worry we have a roller version for you, it may take a bit longer but it still gets the job done.

2. Envelope penetrations
Pipe and wire penetrations can be the down fall of any airtightness testing. Airtight White and Airtight White Brush is applied around objects that penetrate any surface to the external envelope sealing where most tapes and membranes fail. 
Before you apply Airtight White/Airtight White Brush, first apply polyurethane foam around any penetrations; after hardening, remove the excessive foam, and apply generous amount of Airtight White Brush with a flat paintbrush; in all cases, apply a sufficient, well covering layer to guarantee airtightness.

3. Window/Door reveals 
Airtight White can be applied (and is tested) on different construction materials such as concrete, brick, wood, PVC, aluminium, polyurethane foam and with a coat of Airtight White, the whole window/door reveal can be made airtight.
Working method: cut off the excess of polyurethane foam, and apply Airtight White Brush.
