Fibre-Reinforced Brush-On Sealant with a Humidity-Variable sd Value, Blue (wet)/Black (dry)

Advantages

  • Excellent adhesive to most construction surfaces
  • Covers cracks and joints of up to 20mm width
  • Larger joints can be covered in combination with AEROSANA FLEECE
  • Can be used flexibly in all interior applications

Areas of application

AEROSANA® VISCONN FIBRE is a brush-on, elastic and humidity-variable vapour control layer. VISCONN FIBRE creates an airtightness layer for sealing porous surfaces, penetrations and joints. Use as a bonding course between sub-surfaces and subsequent coatings on internal building construction. Thanks to the fibre reinforcement, joints and cracks of up to 20mm can be covered. Use AEROSANA® fleece for larger joints.
