Product Description

This Air Tightness Paint is Aerosana Visconn and comes in a 10 Litres can. Aerosana Visconn Air Tight Paint is a highly flexible liquid-applied air barrier. As a water-based acrylic dispersion sealant, it can be brushed, rolled or sprayed on as a liquid film.

Once dry it forms a seamless, elastic, airtight and humidity variable membrane for filling gaps up to 3mm. Larger gaps can be filled with Visconn Fibre.

Main purpose:

Easy-to-use liquid applied membrane to rapidly airtight seal substrates and areas that would be more difficult (and slower) to seal with tape or are unsuitable for tape.

Use it on:

Smooth or rough brick, blockwork, stone, concrete, timber, wood based sheathing boards and panels. Especially in large or small areas where tape/membrane is difficult, unsuitable or time consuming to apply. Any gaps and cracks must be no more than 3mm wide.


Typical coverage is approximately 8 to 12m2 per 10 litres.

Where to use it:

Primarily used indoors on brick and blockwork to seal porous surfaces and prevent air leakage. It is a viable lightweight alternative to the traditional means of airtightness on masonry buildings where a two coat plaster system would be used. Aerosana Visconn can be combined with vapour open racking boards such as Elka Strong Board in lightweight timber frame buildings to maintain the buildings vapour movement. It can also be used in conjunction with CLT buildings and used externally if in a sheltered location.

The 600ml foil cartridges are specifically designed for use with Pro Clima Aerofixx Applicator Gun. Although the cartridge will fit in a typical 600ml extrusion gun, the consistency is unsuitable for this type of applicator and its nozzle. We would recommend brush application of Aerosana Visconn if you are using 600ml cartridges without an Aerofixx Applicator Gun.

What it does:

Aerosana Visconn liquid membrane creates an airtight film to seal the porous air permeable substrate it is being applied to. Once dried it provides a robust, permanently elastic fully airtight layer while allowing for the movement of harmful levels of moisture with its humidity variable properties. It sticks to all standard construction materials, all Pro Clima membranes and membranes made from aluminium and paper.

How it works:

Aerosana Visconn airtight membrane is sprayed or brushed on in several coats in order to fully seal pores of the substrate to which it is being applied. Once dried Aerosana Visconn creates a film over the substrate it has been applied to and renders the areas airtight but still with a high degree of flexibility for future movement, something not achievable with the use of plaster or even airtight tapes and membranes.

Aerosana Visconn Black has a blue colour when wet and will turn black once it is dried. The white version is the same colour when wet or dry. Where gaps are greater than 3mm in width, it is recommended to use Aerosana Visconn Fibre; this can seal gaps of up to 20mm in width and is applied by brush.

The 600ml foil cartridges of Aerosana Visconn can be loaded into Pro Clima’s Aerofixx Applicator Gun. This applicator gun uses compressed air to spray apply Aerosana Visconn or apply it as a bead.

Why we love it:

The wide range of movements that are common in buildings especially during the drying out phase such as issues of cracked plasters can negatively affect the airtightness of buildings as they dry and settle. Due to Aerosana Visconn’s impressive elasticity, the flexibility of the dried material is of significant benefit and offers an impressive range of movement without compromising its robust airtight properties.

Aerosana Visconn is third party tested by the IFT Rosenheim as a suitable airtight weather resistant material for use in critical window and door junction areas and has been verified and certified by the renowned Passivhaus Institute. Aerosana Visconn White can be used when the sealed area will remain visible and/or needs to blend in with other lightly coloured painted surfaces.

Also useful in situations where light colours are a health and safety requirement (e.g. in a lift shaft).

  • Once dried it has excellent elasticity giving a robust, long term flexible airtightness layer that allows for movement.
  • It is an intelligent airtightness layer with a variable sd value, meaning it maintains vapour movement in the wall/roof.
  • Dries quickly and so allows for better sequencing and more efficient labour on site.
  • Reduces moisture levels on site in comparison to parge coats or a 2 coat wet plaster system on blockwork/ brickwork. ISO 16000 hazardous substance compliant.
