Pro Clima AEROSANA VISCONN FIBRE Liquid Airtight Sealant (Black)

A fibre-reinforced liquid airtight sealant from Pro Clima, brushed on to seal gaps of up to 20mm at junctions and between building components. A quick alternative to taping on awkward details.

Use it for

• Wall-to-ceiling and wall-to-floor junctions
• Gaps, cracks and missing mortar in brick and block walls
• Tolerance gaps around window and door reveals, instead of expanding foam

Suitable surfaces

Brick, block, concrete, timber, wood-based panels, sheathing boards and cement particle boards.

Key features

• Seals gaps up to 20mm wide (standard Visconn only covers up to 3mm)
• Applied by brush in a thick fibrous coat
• Goes on blue when wet and dries black, so you can see when it is ready
• Dries to a flexible, robust, vapour-retarding seal
• Pro Clima airtight tapes and grommets can be bonded to it once fully dry
• Up to 3 months UV resistance, so it can be used in sheltered external areas
• Part of the Pro Clima system, covered by the Pro Clima system warranty
