Fibre reinforced liquid airtight sealant for sealing where the gaps, at critical between building components, are up to 20mm wide.
Fibre-reinforced sealant with a humidity-variable SD value for sealing cracks in walls, floor and ceiling joints and around windows.
This is black when fully dry.
Where is this used?
Aerosana Visconn Fibre from Pro Clima is used as an Air Tightness, Wind Tightness or Retarder layer on floor and ceiling joints, windows and walls and can be either brushed on or sprayed using the spray gun.
It is designed to seal sub surfaces that are not airtight or wind tight and any penetrations such as foamed window joints.
It can be used both indoors and in protected outdoor areas and also used as a bonding course between subsurfaces and subsequent coatings or adhesion.
As it is reinforced by fibre, you can cover and seal cracks and joints that are up to 20mm (3/4").
Use it on brickwork, blockwork, concrete, timber, wood based panels (including wood-wool boards), sheathing and cement particle boards.
This can be used to seal below surface LCF block and around windows and doors along with any other service penetrations.
Benefits of using Pro Clima Aerosana Visconn Fibre
- It comes ready to use so saves you time
- The excellent adhesive properties are suitable for all standard construction surfaces and feature reliable structures within the product
