Airtight Coatings HevadexApply Blowerproof Liquid on the concrete surface prior to the floor insulation and floor screed being installed, and prior to the inside wall finish being done. 

  • On ground level: trim back protruding DPC level. Remove standing water;
  • Fill gaps greater than 2mm with non-shrink gap filling mortar or non-shrink polyurethane foam. Do the same for joints, pipes, cables, ducting, joists and all other penetrations.
  • Apply over an area sufficient to overlap finish plaster or render by 50mm and in all cases a minimum of 50mm above DPC at ground level.
  • Ensure a minimum overlap of 500mm when connecting interior walls to outside walls.
  • Apply BLOWERPROOF LIQUID in two coats ensuring that the first coat is fully dry before applying the second coat.

  • Concrete bricks, no finish
  • Blowerproof Liquid for airtightness and vapour controll
  • Thermal insulation anchored and glued on Blowerproof Liquid
  • Facade finish such as facade bricks, render, etc.

WHAT DOES BLOWERPROOF DO?

BlowerProof 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 is the fast, flexible and durable solution for all airtight connections.
