Product details
Installation steps
Application using brush or scraper
1. Stir the product
Before application from the tin: stir thoroughly.
2. Clean the subsurface
Clean loose material and coarse dirt from the subsurface using a brush, for example.
3. Determine the crack width
AEROSANA VISCONN FIBRE bridges cracks of up to 20 mm in width.
4. Painting over cracks up to 8 mm in width
Cracks of up to a maximum of 8 mm in width can be simply painted over. Guide the brush flat across the crack so that the gap becomes completely filled.
5. Filling cracks up to 20 mm in width
For cracks of 8 - 20 mm in width, apply AEROSANA VISCONN FIBRE deep into the crack.
To do so, the gap must be filled with sealant to a depth of at least half the width of the gap.
6. Closing up holes
Holes of up to a maximum of 70 mm in diameter at their widest point can be closed using AEROSANA FLEECE and AEROSANA VISCONN FIBRE.
7. Paint the subsurface
Apply AEROSANA VISCONN FIBRE with a thickness of at least 1 mm around the hole.
8. Apply the fleece
Cut AEROSANA FLEECE to shape and apply this onto the liquid sealant.
Avoid cavities. The bridging fleece must be in contact with the masonry over a width of at least 40 mm around the hole.
9. Paint over the fleece
Paint over the entire area of the bridging fleece with AEROSANA VISCONN FIBRE.
11. Sealing around penetrations
When creating joints to penetrations, clean loose material and coarse dirt from the subsurface with a brush, for example.
12. Determine the fleece strip length
Determining the strip length of AEROSANA FLEECE: the bridging fleece must be in contact with the masonry and the pipe to be bonded over at least 40 mm for each.
13. Cut the fleece strip
Cut a strip of AEROSANA FLEECE in such a way that its width is slightly greater than half the pipe diameter. The strip can then be worked onto the pipe more easily.
14. Paint the subsurface
Apply AEROSANA VISCONN FIBRE with a thickness of at least 1 mm around the hole and pipe.
15. Apply the first fleece layer
Apply the fleece pieces onto the liquid AEROSANA VISCONN FIBRE. Ensure that the valleys formed are free of tension.
16. Paint over the fleece
Then apply AEROSANA VISCONN FIBRE to the fleece strips, the masonry and the pipe.
17. Apply the second fleece layer
Apply additional fleece strips so that the gap is completely closed. Avoid hollows (valleys).
18. Paint over the fleece
To finish, paint over the joint generously with AEROSANA VISCONN FIBRE.
20. Awkward detail features
AEROSANA VISCONN FIBRE can be used to achieve airtightness for geometrically challenging joints (e.g. on renovation projects) in a simple and reliable manner.
21. Paint the subsurface
Paint AEROSANA VISCONN FIBRE with a thickness of at least 1 mm onto the subsurfaces to be sealed.
In the case of changes of material or close to corners, the brush-on sealant must be applied onto at least 40 mm of the subsurfaces.
22. Apply the first fleece layer
Cut pieces of AEROSANA FLEECE into shape and apply them onto the wet AEROSANA VISCONN FIBRE.
23. Paint over the fleece
Paint the brush-on sealant onto AEROSANA FLEECE in the area around overlaps to ensure they stick to one another. Once all fleece pieces have been fitted, paint all of the joint with AEROSANA VISCONN FIBRE.
24. Protection against moisture
The drying time for the joint created is around 4 - 24 hours depending on the absorbency of the subsurfaces and the climate conditions. During this time, the joint must be protected against moisture.
25. Colour change after drying
The colour changes to black during drying.
If gaps are noticed after application, these can be closed subsequently with AEROSANA VISCONN FIBRE.
Eave refurbishment with AEROFIXX
1. Preparation
Brush off subsurfaces; if necessary, clean with a vacuum cleaner and wipe down.
2. Spray over birdsmouth joints
In the area around the birdsmouth joints, spray over the joints between rafters and the wallplate with a generous amount of sealant so that any movement of components that occurs can be accommodated.
3. Continue along the rest of the eave
Also apply a generous amount of AEROSANA VISCONN / FIBRE below the rafters in the area around the birdsmouth joints.
4. Seal wide joints
Switch the AIRFIXX to line application and completely fill the gap (in this case, between the wallplate and the knee wall) with AEROSANA VISCONN / FIBRE.
5. Spray over the joint
Set the AEROFIXX to spray application and spray over the joint in a generous manner. Apply the sealant to a width of at least 30 mm on the surfaces to be sealed. The layer thickness is sufficient when a textured surface (‘orange peel’) is recognisable.
6. Use as a primer
If required, apply AEROSANA VISCONN /FIBRE as a primer onto timber that the refurbishment vapour control membrane (e.g. DASATOP) will be bonded to subsequently.
7. Stick the joint
After the sealant has fully dried, seal the refurbishment vapour control membrane in an airtight manner using TESCON VANA, for example.
Joints at double collar ties with AEROFIXX
1. Initial situation
2. Preparation
Brush off subsurfaces; if necessary, clean with a vacuum cleaner and wipe down.
3. Check the joint width
Gaps of up to 3 mm can be filled using AEROSANA VISCONN. Use AEROSANA VISCONN FIBRE for wide gaps of up to 20 mm. In this case, the gap must be filled with sealant to a depth of at least half the width of the gap.
4. Set the device
Set the AEROFIXX to line application.
5. Fill the joint
Fill the joint with a sufficient amount of AEROSANA VISCONN / FIBRE.
6. Spray over the joint
Set the AEROFIXX to spray application and spray over the joint in a generous manner. Apply the sealant to a width of at least 30 mm on the surfaces to be sealed. The layer thickness is sufficient when a textured surface ('orange peel') is recognisable.
7. Work on detail features
Areas that are difficult to access can also be sealed conveniently using the spray method.
8. Check the joint
If necessary, seal any gaps with a brush and AEROSANA VISCONN / FIBRE.

Window joint with AEROFIXX
1. Initial situation
Window is installed, window joint has been filled with insulation material.
2. Preparation
Brush off subsurfaces; if necessary, clean with a vacuum cleaner and wipe down.
3. Cut away any excess insulation material
If necessary, cut away any protruding insulation.
4. Apply masking tape to the window frame
When doing this, leave a strip with a width of at least 6 mm free on the frame for subsequent sealing using AEROSANA VISCONN / FIBRE.
Alternatively, remove the joint insulation to a sufficient extent to create a clean surface for a lateral bond to the side of the window frame.
5. Spray on the sealant
Spray a sufficient amount of AEROSANA VISCONN / FIBRE onto the window frame, the joint insulation and the adjacent masonry. Apply the sealant evenly. Cracks and pores must be closed by flooding them. The layer thickness is sufficient when a textured surface (‘orange peel’) is recognisable.
6. Continue around the rest of the window
Bond all four sides of the frame to the masonry using AEROSANA VISCONN / FIBRE.
7. Check the joint
If necessary, seal any gaps with a brush and AEROSANA VISCONN / FIBRE.
8. Interior and exterior use
AEROSANA VISCONN / FIBRE can be used for interior and exterior window joints. The installation method is identical in both cases.
9. Remove the masking tape
Remove the protective masking tape immediately after the window joint is sealed.
Remove any traces of AEROSANA VISCONN / FIBRE from the window frame immediately using a damp cloth.

Sealing wall-to-floor joints with AEROFIXX
1. Preparation
Brush off subsurfaces; if necessary, clean with a vacuum cleaner and wipe down.
2. Preparation of taped joints between boards, if required
If the gaps between adjacent wood-based panels have been taped using TESCON RAPIC to create airtight seals, this tape should be covered over with short lengths of TESCON VANA in the area close to the floor where a liquid sealant will be applied. The edges of the TESCON VANA must adhere directly onto the wood-based panel here.
3. Spray setting
Set the AEROFIXX to spray application.
4. Spray over the base joint
Spray the wall-to-floor joint area. Apply the sealant to a width of at least 30 mm on the surfaces to be sealed.
The layer thickness is sufficient when a textured surface (‘orange peel’) is recognisable.
General conditions
Openings in the subsurface, e.g. cracks, may have a maximum width of 20 mm. Cracks of up to a maximum of 8 mm in width can be simply covered by applying sealant with a brush or spray gun.
For cracks of 8-20 mm in width, apply AEROSANA VISCONN FIBRE deep into the crack. To do so, the gap must be filled with sealant to a depth of at least half the width of the gap.
In the case of larger joint or crack widths, use AEROSANA FLEECE or an adhesive tape (e.g. TESCON VANA).
Alternatively, the opening can be filled using suitable plaster or mortar.
AEROSANA VISCONN FIBRE changes colour from blue to black when it dries. AEROSANA VISCONN FIBRE white does not change colour.
The film is to be protected against moisture (e.g. rain) during drying.
Protective equipment
The air pressure raises airborne dust. For this reason, it is recommended that installers should wear personal protective equipment consisting of a mask, protective glasses and gloves, even in well-ventilated locations.
AEROFIXX application
The AEROFIXX device is connected to a compressor with a suction flow rate of >300 l/min. The pressure should be set to 6 bar. All AEROSANA VISCONN variants in 600 ml foil cartridges can be applied using the AEROFIXX device. You can easily switch between line (bead) application and spray application by turning the spray head.
Application with a brush
All AEROSANA VISCONN variants can be applied using a brush. To ensure efficient working, the width of the brush should be ≥ 50 mm. Check the minimum layer thickness of 500 μm using a measuring gauge.
Storage
If this product has been in storage for a longer period, water (~5%) can be mixed into it to achieve a consistency that is suitable for spraying. Do not dilute the sealant material too much (risk of excessive flow and poor coverage of cracks). Closing the container in an airtight manner and covering it with a thin sheet will help to prevent drying out.
