Blowerproof WHITE Liquid Brush is used for the discrete airtight sealing of boards, blockwork and masonry prior to the 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.

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.
