Fibre-reinforced brush-on sealant with a humidity-variable sd value (g value, permeance)
Advantages
- Time-saving: Ready-to-use brush-on sealant
- Reliable structures thanks to excellent adhesive properties on all standard construction surfaces
- Covers cracks and joints of up to 20 mm (0.8") width. Larger joints can also be covered in combination with AEROSANA FLEECE.
- Can be plastered, painted and stuck over with all pro clima adhesive tapes
- Can be used flexibly both in interior and protected outdoor areas thanks to its humidity-variable sd value
- Excellent values in the hazardous substance test, has been tested according to the ISO 16000 evaluation
Application
For use as an elastic, humidity-variable vapour retarder, airtightness or windtightness layer for wall, ceiling and floor joints, to seal penetrations and non-airtight or non-windtight subsurfaces, e.g. on foamed window joints.
Also for use as a bonding course between subsurfaces and subsequent coatings or adhesion. Can be applied both in interior and protected outdoor areas.
Thanks to fibre reinforcement, joints and cracks of up to 20 mm (0.8") can be covered and sealed. Apply AEROSANA FLEECE to larger joints.
