It is critical to restrict the entry of moisture and close any gaps or cracks in the building fabric for lasting structural stability and to truly achieve energy efficiency. This airtightness paint by Blowerproof lets you do just that.
This easy-to-apply liquid-based vapour control layer by Blowerproof dries to form a flexible, durable, airtightness membrane. Since it adheres very quickly to different building surfaces like bricks, wood, concrete etc, it forms a seamless and continuous membrane that protects your home from moisture and air by sealing all gaps and cracks.
The best part is that it perfectly sticks to the contours of the surface, even the toughest of spots and completely seals any gaps or spaces. Airtightness membrane is a quicker, more durable and lasting solution for all airtight connections in a building including steel decks, walls, pipes, service penetrations, ducting, roofs, floors etc. It can be applied to even damp surfaces and once dried you can paint, plaster or render it
It is free of any VOCs or hazardous chemicals and the dried materials can also be discarded as non-hazardous waste. It also protects your home from the harmful effects of radon. The brush and other tools, if used, can be easily cleaned after the application as well. It is BBA approved and is certified by the Passive House Institute.
