Sprayable airtightness sealant with humidity-variable water vapour permeability, blue/black

Advantages

  • Time-saving and can be applied in versatile ways: spraying with an airless sprayer or AEROFIXX (compressed air), paint on.
  • Reliable structures thanks to excellent adhesive properties on all standard construction surfaces
  • Covers cracks and joints of up to 3 mm (1/8") width. Larger joints can also be covered in combination with AEROSANA FLEECE.
  • For robust building components: permanent elasticity and high durability once it has dried
  • Improves surfaces: forms a bonding course between subsurfaces and subsequent coatings
  • Can be plastered/painted over, pro clima adhesive tapes can be stuck onto it
  • Flexible use in indoor and protected outdoor areas thanks to its humidity-variable sd value
  • Excellent values in hazardous substance testing, has been tested according to the ISO 16000 evaluation scheme

Areas of application

For use as a humidity-variable vapour check and airtight layer that can be applied as a spray or using a brush on wall, ceiling and floor surfaces, such as non-plastered masonry or porous panel-form materials.

  • Also for the creation of joints to components such as windows, roofs, walls, ceilings and floors, and for panel joints on airtight wood-based panels (e.g. OSB).
  • Can also be used for strengthening subsurfaces in the case of renovation.
  • The humidity-variable diffusion resistance of this product means that it can be used on the interior and exterior of building components.
  • The sprayed-on liquid film forms a seamless, elastic air-retarding and vapour-checking protective layer once it has dried.
  • Forms a seamless, elastic airtight and vapour-checking protective layer once it has dried.
