Blowerproof Liquid Brush Membrane In Blue/Black – 5kg

Blowerproof Liquid Brush is a liquid membrane compatible with any substrate that creates a seamless airtight and vapour tight seal over gaps and cracks. The fibre-reinforced polymer uses its flexibility and high adhesion to follow the contours of the substrate and provide a long-lasting air tight seal. This sustainable product is VOC free and water-based so it can be used on any substrate on roofs, walls, floors, window jambs, pipe penetrations and more.

BBA-certified Blowerproof Liquid Brush is simple to apply and even simpler to maintain – you just clean it with water! The unique system can be painted and plastered over directly too so using Blowerproof Liquid Brush won’t delay or put up barriers for a project.

Substrates should be free from dust and any gaps bigger than 5mm should be filled with the Blowerproof Gap Filling Mortar, available in 5kg tubs as in the ‘Frequently Bought Together’ section to the right.

Blowerproof Liquid Brush is a viscous product that lends itself to thick layers, however each of the two layers should not be thicker than 7mm each and 14mm overall. The product is blue when painted on and when it cures it goes black, signaling that it’s dry. Once the first coat of blue/black Blowerproof Liquid Brush has turned black, paint another layer no thicker than 7mm over the top.
