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 retrofits.
The water-based polymer is brush applied to create an uninterrupted air and vapour -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.
