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.

This 300 gram cartridge is designed for precise application of the product to door jambs, window jambs and other hard-to-reach locations. For sealing between boards or perimeter joints, the depth should not exceed 10mm. Blowerproof Liquid Brush 300 gram cartridge is to be applied as a single or double bead and then brushed to finish.
