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

Excellent values in the hazardous substance test, has been tested according to the AgBB evaluation scheme / ISO 16000

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)
