AEROSANA® VISCONN
Sprayable Airtightness Sealant with a Humidity-Variable sd Value
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 components 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.
Window-sealing, airless
1. Cut away protruding foam
Insert the insulating material (loose wool, loose hemp) into the window joint in such a way that is flush with the window frame.
Cut away protruding foam after it has hardened.
2. Clean the subsurface
3. Protect the window with sheeting
Protect the panes of glass and visible parts of the frame against soiling by using masking tape.
4. Spray the lintel and reveals
Apply the required layer thickness of AEROSANA VISCONN in one or two spraying steps.
5. Check the layer thickness
Check the required wet layer thickness of 500 μm using a suitable gauge.
6. Pre-spray the sub-sill flashing
AEROSANA VISCONN is also suitable for use in forming sub-sill flashing.
To do this, first spray the insulation angle fillet in a generous manner.
7. Install the AEROSANA FLEECE sub-sill flashing
Insert the AEROSANA FLEECE into the still-wet AEROSANA VISCONN spray film, ensuring there are no folds or creases.
Carefully finish any corners or raised edges.
8. Spray over AEROSANA FLEECE
The AEROSANA FLEECE is embedded in place by spraying again with AEROSANA VISCONN.
9. Remove the protective sheeting
Remove the stuck-on protective sheeting before AEROSANA VISCONN dries.
