Blowerproof Airtightness Membrane - 10Kg - White

Spray or roll-on airtightness membrane by Blowerproof is an easy-to-use and durable airtightness solution and vapour control on entire walls, connections and service penetrations of a building. 

Airtightness membrane quickly adheres to most building surfaces like wood, mortar, PVC or even insulation. It perfectly covers any gaps, cracked or small holes on the building surface. It is also easy to apply to the corners or spaces that cannot be easily reached like those in the roof/wall or wall-floor connections.

Upon drying it forms a flexible, continuous and lasting membrane that protects your building from any water or air entry. It also acts as an intelligent vapour control layer. It protects your building from the harmful effects of radon rays. It is free of any VOC and harsh chemicals, so it is safe to use. Since it does not contain any organic- solvents, even the dried material can be discarded as non-hazardous waste.

Airtightness membrane by Blowerproof is very easy to use. Prepare the solution just when you are ready to use it. Simply apply it using a roll-on or spray it using an airless spray device onto the substrate. It is much better to use this liquid membrane than dealing with any paper-based vapour control layers where you have to tape or staple them whilst taking extra care to keep them from getting damaged.
