Where to use Blowerproof

Applications

Available in a brush or spray version this highly versatile product provides a secure and permanent airtight seal that is simple, quick and easy to apply. Blowerproof can be used on a wide variety of common building surfaces and even on damp substrates. With only one product for all applications coupled with super fast application rates this is a guaranteed and proven way to save you money and give long lasting secure airtight seal. Blowerproof is  designed to give ultimate peace of mind.

 

Wall/Ceiling connections are easily and quickly sealed with Blowerproof Liquid Brush or Spray even on different types of material such as brick, concrete or steel. Different materials react differently to changes in humidity and temperature, which can lead to small cracks in plaster or other finishes leading to air leaks. Applied in two coats second coat must only be applied when the first coat has turned completely black.

Window jambs are so simple and quick to seal, (Download the Airtightness Test for Windows), first fill larger gaps between the window frame and the wall with PU foam, then apply protection tape on the profiles at about 5mm from the side, next simply brush on Blowerproof Liquid Brush directly onto the wall and window surfaces (and over the hardened gap filling foam) remove the tape immediately after application, any spills can be easily cleaned with water.

Walls can be a problem to make fully and reliably airtight, not so with Blowerproof Liquid Spray. (Download the Airtightness Test for Walls). Spray application ensures complete and secure coverage in double quick time. Blowerproof Liquid can be directly applied over a wide range of substrates including brick, masonry, concrete, timber, plaster, render and even mineral wool insulation. Treated surfaces can be over-painted, plastered or rendered directly onto the Blowerproof Liquid, which is also available in white for use under a finish plaster.

Pipe penetration gaps are one of the main contributors to failing airtightness tests. Sealing is so simple with Blowerproof Liquid: first fill any gaps around the pipes with rapid setting cement or polyurethane foam and apply 2 layers of Blowerproof Liquid Brush with a flat paintbrush. Seals easily and quickly around any shape, especially useful for retrofit and difficult to access applications.

Floor/Wall connections are a vital area to seal in order to meet high levels of airtightness, (Download the Floor to Wall Airtightness Test), once a floor covering is in place it’s very difficult to rectify leaking connections. Apply Blowerproof Liquid to a dust free, solid surface, and fill cracks or gaps beforehand: large holes and joints > 5mm can be repaired with a fast setting cement based product or PU foam, small holes and joints 2-5mm can be sealed with Blowerproof Liquid Brush.
