Product benefits

The text on this page was automatically translated. Minor translation errors are possible. In case of doubt, the original versions (Dutch and French) are correct.

  • Reliable air sealing - even for hard-to-reach details
  • Bridges joints, cracks, and gaps up to 20mm
  • Durable: remains elastic and firm after drying
  • For indoor and outdoor use - moisture-variable µd value
  • Excellent adhesion to common building materials

Installer benefits

  • Blue, turns black after drying
  • Spreadable with a brush
  • Sprayable with AEROFIXX air pressure gun - even on previously dusty surfaces
  • Easier work - also applicable as an airtight primer to improve the surface
  • Compatible - with pro clima adhesive tapes
  • Plasterable and paintable

Applications

Suitable for:

  • Airtight connection floor/wall and wall/ceiling 
  • Air sealing of unplastered building parts (base block, wall under the water barrier, wall behind hanging toilet, etc.) 
  • Air sealing of exposed masonry on the outside 
  • Also suitable for airtight connection of windows/doors with the construction 
  • Also suitable for fixing surfaces during renovations.

Installation steps

General installation steps

1. Prepare the subsurface; stir the product

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 AEROSANA FLEECE.

General installation steps

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.

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.

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.

2. Spray over birdsmouth joints

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.

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.

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

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.

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.
