AEROSANA® VISCONN
Sprayable Airtightness Sealant with a Humidity-Variable sd Value, Blue (wet)/Black (dry)
Item number: 1AR01106 | GTIN: 4026639211064
Advantages
- Sprayable airtightness sealant with a humidity-variable MVTR
- Can be plastered/painted over
- Suitable for application in indoor and protected outdoor areas, thanks to its humidity-variable MVTR
- Lowest VOC rating in hazardous substance test.
Areas of application
For use as a humidity-variable vapour control and airtight layer that can be applied as a spray or with a brush. It is suitable for wall, ceiling, and floor surface applications, such as non-plastered masonry or porous panel-form materials. AEROSANA® VISCONN can also be used for creating joints to components such as windows, roofs, walls, ceilings, and floors. Use on the interior and exterior of building structures due to the product's humidity-variable diffusion resistance. Once dried, the sprayed-on liquid film forms a seamless, elastic, airtight, and vapour-controlling protective layer. It sticks to all standard construction materials, pro clima membranes and membranes made from aluminium and paper. Sprays on blue, dries black.
General installation steps
1. Prepare the subsurface; stir the product
Subsurfaces should be cleaned. An even subsurface is a prerequisite for the use of AEROSANA VISCONN spray film. Fill any breakages, joints or holes before applying it.
Before application from the bucket: stir thoroughly.
2a. Cover over defects
Breakages, joints and holes can be covered over with a suitable filler or with CONTEGA SOLIDO SL before AEROSANA VISCONN is sprayed on.
If defects are detected during spraying, these can be covered over with pro clima AEROSANA FLEECE.
2b. Cover over defects
To do this, paint AEROSANA VISCONN onto a piece of fleece, apply the fleece to the defect and spray over it.
3. Apply a spray film (airless spray process)
Apply AEROSANA VISCONN in at least two layers.
Apply the spray film in an even and overlapping manner.
Additional layers may be necessary, depending on the condition of the subsurface.
In the case of a layer thickness of greater than 1 mm, first allow AEROSANA VISCONN to become touch dry and then proceed to add further layers.
Layers of liquid film that are too thick can run off.
Setting of airless sprayer
Pressure: Approx. 150 - 200 bar
Nozzles: 210, 317, 519
4. Use as a primer
Rough or dusty subsurfaces can be prepared for sticking pro clima adhesive tapes to them by using AEROSANA VISCONN.
To do this, apply a seamless layer of spray film.
Note:
The colour of AEROSANA VISCONN changes from blue to black during drying.
5. Stick joints
Once the spray has dried, apply the adhesive tape and gradually stick it in place.
When plastering, please observe the recommendations of the plaster manufacturer for non-absorbent subsurfaces.
A bonding course may be necessary.
