Blowerproof Liquid ‘Brush’ is a VOC free, water based, flexible, fibre reinforced, polymer providing a unique and sustainable solution for the production of airtight building connections in both new build and retrofit.
The water based polymer is brush applied to create an uninterrupted air and vapour-tight seal around penetrations, and for floor / wall connections, wall / ceiling joints, and roof connections Blowerproof Liquid creates a seamless, continuous air and vapour-tight seal over cracks and gaps. Because the seal perfectly follows the contours of the substrate and in combination with the high flexibility and superior adhesion, the connections remain airtight over the long term. Blowerproof Liquid is the fast, flexible and durable solution for all airtight connections.
Ideal for sealing.
- Service penetrations, pipes, cable, ducting etc
- Floor to wall junctions
- Ceiling to wall junctions
- Window / door jambs
- Steel decks
Blowerproof Liquid Brush is supplied as a blue paste which turns black when cured (dependent on ambient temperature) after which time a second coat may be applied. Blowerproof Liquid Brush comes in a resealable 5kg or 2.5Kg tub. Allow up to 1kg per square metre on highly porous surfaces for non porous surfaces allow 750grams per square metre. Two coats are recommended at no more than 5mm per coat, on smooth or non porous surfaces one coat may be applied – see application guide (download link at the bottom of this page).
Overall coverage should not exceed 10mm Also available in WHITE used for the discrete airtight sealing of boards, block-work and masonry prior to the direct application of a plaster skim. This highly flexible liquid applied membrane is the perfect solution for sealing joints, corners and penetrations when using plaster as the principle airtight layer.Board junctions, edges and corners are more likely to suffer from movement cracks, using Blowerproof WHITE Liquid Brush eliminates leakage through movement or cracks due to plaster shrinkage. Quick and easy to apply by brush the membrane can be directly over-plastered, and being white remains invisible behind the plaster.
300g Cartridge (fits standard skeleton gun) use for precise and economic location of Blowerproof brush as a bead, especially useful around windows, doors, joist ends, penetrations and difficult to reach areas, simply brush to finish, can also be used to seal gaps and joint OSB boards.
Gap Filling Mortar: 5Kg rapid setting non shrink gap filling mortar, use to fill a wide range of construction gaps, excellent adhesion, does not shrink or bleed, no harmful VOC’s or chemicals, mix in the tub, for gaps >2mm to 50mm in a single application.
