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 (3/4") in width.
4. Painting over cracks up to 8 mm (5/16") in width
Cracks of up to a maximum of 8 mm (5/16") in width can be simply painted over.
When doing so, guide the brush flat across the crack so that the gap becomes completely filled.
5. Filling cracks up to 20 mm (3/4") in width
For cracks of 8 - 20 mm (5/16"- 3/4") 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 (2 3/4") 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 (40 mils) 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 (1 5/8") around the hole.
9. Paint over the fleece
Paint over the entire area of the bridging fleece with AEROSANA VISCONN FIBRE.
11. Joints to 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 (1 5/8") 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 (40 mils) 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 (40 mils) 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 (1 5/8") of the adjacent surfaces.
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.
