Product Specifications
Applications
Liquid-applied air barrier for robust connections. For use as WRB, flashing for pitched windows sills, and other detailing. VISCONN® can be brushed, rolled, or sprayed as a liquid film and dries to form a seamless, elastic, airtight and vapor-variable membrane.
Coverage
2.5 Gallons (10 L)/ container
Coverage per container:
~125ft² when applied with brush
~170ft2 when applied with airless sprayer
[coverage dependent upon applied thickness]
Advantages
- Time-saving airsealing of difficult junction because of airless spray/brush application
- PHI-Certified airbarrier - for interior with vapor-variable properties
- IFT Rosenheim certification as airtight/waterproof joint sealing for insulated window frame rough opening gaps
- For use as WRB on exterior behind rainscreens when shielded from long term UV exposure
- Use appropriate safety protection when using airless sprayer
- Available in two color options: one that is blue when wet and dries black to confirm drying, one that is white when both wet or dry
Substrates
- Apply to walls, ceilings and floor surfaces, such as masonry, CMU, wood sheathing, fiberboard, joists or joist bays
- Reliably fills gaps of 1/8”; deeper joints or thick coats result in longer cure times
- Highly porous/uneven materials require 2 or more coats for reliable coverage/airsealing
- It may be necessary to apply more than one coat in the case of uneven or rough subsurfaces
- Can be plastered/painted over, Pro Clima® adhesive tapes can be bonded onto it (and can be sprayed over all TESCON/CONTEGA Pro Clima® tapes)
