Blowerproof is a new liquid air-tight membrane designed to provide a quick, easy and cost-effective way to ensure air-tightness in construction gaps. Simply brushed on, Blowerproof quickly forms a permanent, secure and continuous air-tight seal across a range of draught-prone points: wall/floor/ceiling connections, fenestrations, and pipe connections including water, electricity, gas and data.
When sealing construction gaps, one common option is to use a polyurethane-based spray foam filler, or a silicone or acrylic sealant to ensure air-tightness, but these bring acknowledged problems, with shrinkage and adhesion being the main disadvantages. Blowerproof on top of these materials provides an assured air-tight covering.
Applied as a blue, thick, liquid fibre reinforced ‘paint’, Blowerproof Liquid Brush quickly cures to form a black sealed membrane which is highly resistant to punctures.
